List of recent Galaxy S20 guides
Here is a list of recent Galaxy S20 guides. For a complete list of Galaxy S10 guides, please check the Galaxy S20 guides.
Enhanced processing is one of the prominent new features in Galaxy S20 Android 11 update.
This Galaxy S20 guide explains what the enhanced processing is, how to enable it from Settings and quick settings panel and how to use enhanced processing on Galaxy S20 with Android 11 update.
The enhanced processing option is available after you upgraded Galaxy S20 (and Galaxy S10, Galaxy Note 10, and Galaxy Note 20) to Android 11. If your Galaxy S20 is still running Android 10, please check this guide on how to use and customise the power mode.
What is enhanced processing on Galaxy S20 with Android 11 update?
But Samsung hasn’t offered a detailed explanation of this feature, except stating:
Get faster data processing for all apps except games. use more battery.
There are some wrong inceptions on this feature on the internet. Some mistakenly thought the enhanced processing is simply the old high-performance mode.
So, what is enhanced processing?
First, the enhanced processing, once enabled, can unleash the full CPU (and GPU) power so that the app can run faster.
Second, the enhanced processing works with power saving mode. In other words, you can use this feature even in the power saving mode.
It sounds confusing. But it makes sense.
Apparently, the enhanced processing actually unleash the CPU power on demand. When you are using an app in the power saving mode, in the past, the CPU speed is capped. Now, with the enhanced processing, the limit can be removed on demand with other restrictions (e.g., brightness) in place. Of course, it does not affect background apps.
Third, enhanced processing is a standalone feature.
Galaxy S20 Android 11 update simplified the power modes to 2 modes only: default mode and power saving mode. The enhanced processing adds the option to speed up the CPU speed on demand for active (foreground) apps. This addressed the battery consumption issue in the old performance mode.
At the same time, there are many complaints about the old medium power saving mode, which slows down the apps noticeably. Some owners question the rationale of limiting the speed for the foreground apps. The enhanced processing addressed this … Read the rest

This Galaxy S20 guide explains the changes in using and customizing widgets on Galaxy S20 lock screen and always-on display (AOD) screen, shows you how to use gestures to access widgets on Galaxy S20 lock screen and AOD screen.
Please note, widgets screen on Galaxy S20 is a feature of One UI 3.0, not an Android 11 feature. So, this guide applies to other Samsung Galaxy phones with Android 11, e.g., Galaxy S10, Galaxy Note 10, and Galaxy Note 20.
What are the changes for using widgets on Galaxy S20 lock screen and AOD screen with Android 11 update for Galaxy S20?

This Galaxy S20 guide explains why you should update Galaxy S20 regularly, when and how to update Galaxy S20 to Android 11 (and One UI 3.0), and how to enable and play the Android 11 Easter egg game (Neko Cat) on Galaxy S20.
Android 11 (with One UI 3.0) update has been rolled out to a few Samsung Galaxy devices including Galaxy Note 20, Galaxy S10, and Galaxy Note 10, in addition to Galaxy S20. This guide applies to all these phone models.
Why should you update Galaxy S20 regularly?
Many Galaxy S20 owners may be scared by updates, possibly due to poor user experiences in the past, for example, losing personal data or customisation. Therefore, some owners may refuse to update Galaxy S20.
This is dangerous.
First, Android monthly security update (patch) is essential.
You may be unaware that there are many prying eyes (through apps) on Galaxy S20. Some bad guys may use some exploits or bugs to gain unauthorised access to your personal or sensitive data on the device.
Android monthly security update patches and fixes some exploits and bugs to keep your Galaxy S20 relatively safer.
Of course, the update cannot stop apps from collecting data because you granted permission. But it can prevent unauthorised data collection.
In some regions, Samsung issued the update monthly. In other areas, the update may be delivered quarterly depending on your region. Samsung has a good record of updating Galaxy S phones for about 3 years.
Second, Android updating is matured.
In the past, some users might encounter some issues after the update. Some data went missing mystically. Some customisations were lost under your nose.
Sometimes, the update might break your favourite apps.
These issues have become rarer in recent years, thanks to the improved and matured Android update system.
New versions of Android brings new life for Galaxy S20.
Each version of Android adds some new features and improvements. In recent releases, privacy, security, and data protection are the focus of Android core update.
At the same time, Samsung uses the Android version update to bring new versions of the One UI, which improves the usability and adds some new features as well.
This Galaxy S20 guide explains what Galaxy S20 lockdown mode is, when to use it, how to enable and exit the lockdown mode.
The lockdown mode is available in all Samsung Galaxy phones with Android Pie (Android 9), Android 10, or Android 11. So, this guide applies to not only Galaxy S20 phones but also Galaxy phones with Android 9 and later versions including Galaxy S8, Galaxy S9, Galaxy S10, Galaxy Note 8, Galaxy Note 9, Galaxy Note 10, and Galaxy Note 20.
What is Galaxy S20 lockdown mode?
Galaxy S20 lockdown mode, once activated, blocks all biometric security (face unlock and fingerprint) and smart lock. In the lockdown mode, the only way to unlock your Galaxy S20 is using the primary PIN, Pattern or Password.
Voice recognition (Bixby and Google Assistant) will also not work when the lockdown mode is activated.
Besides, all notifications that would usually be displayed on the Galaxy S20 lock screen will be hidden, and you can only read them after you unlock the phone.
In a nutshell, Galaxy S20 lockdown mode:
- Force you to use PIN, Pattern or Password to unlock Galaxy S20.
- Hide all notifications from the lock screen regardless of the notification settings for the lock screen.
Therefore, it is a security feature, not a convenience feature.
Please note, Galaxy S20 lockdown mode is a one-time feature. It means it will return to normal once you unlock Galaxy S20 with PIN, pattern or password. If you need the mode again, you have to activate it again.
If you want to use the lockdown mode permanently, you may set the phone in this way:
- Delete the registered facial features and fingerprints
- Reset the smart lock and remove any trusted devices and locations.
- Choose not to show any notification on the lock screen.
- Disable Bixby and Google Assistant on the lock screen.
Anyway, this would cause some inconveniences.
When to use Galaxy S20 lockdown mode?
Samsung officially released Galaxy S20 Android 11 update in early December 2020 globally. Galaxy S20 owners in most regions will get the Android 11 update (One UI 3.0) by the end of 2020.
Of course, in a few regions, owners have to wait and will get the update in January or February 2021.
Galaxy S20 Android 11 update brings a refreshed One UI 3.0 with most (not all) Android 11 features. This Galaxy S20 guide explains the top 11 new features in the Galaxy S20 Android 11 update to help you jumpstart with the new UI and new features.
This guide applies to all Galaxy S20 models (Galaxy S20, Galaxy S20 FE, Galaxy S20+, and Galaxy S20 Ultra) because the new features and the new UI are almost identical on all these phones.
Please follow this guide to update Galaxy S20 to Android 11.
One UI 3.0 with a refreshed visual design
Samsung now updates One UI with each Android update. With Galaxy S20 Android 11 update, One UI was updated to version 3.0 with a refreshed visual design.
You will find One UI 3.0 offers generous space (empty region). But there are fewer wasted spaces compared to One UI 2 and One UI 2.5. So, most users will feel more relaxed when using the phone.
One UI 3.0 also introduced a few new visual effects to help you quickly focus on what matters most.
But they are controversial. Some owners probably will not like some of them. For example, the blurred effect for notifications may irritate some users depending on the wallpaper used. Unfortunately, Samsung did not offer the options to turn them off, at least, up to now.
Overall, aesthetic improvements in One UI 3.0 are obvious. They make the UI modern and stylish.
Please note, Samsung removed the feature of customising the app icon shapes in this Android 11 update.
Some major improvements and new features in Android 11 are notification related. They make notifications very convenient to use, intuitive and interactive.
Samsung implemented almost all of them and added a few of their own.
Sometimes, you may want to re-read a few notifications that were dismissed inadvertently. Or you may just want to check whether you missed any important notifications.
Android 11 introduced notification history, which allows you to check all notifications (of course including dismissed and silent notifications) in the … Read the rest
This Galaxy S20 guide explains what Galaxy S20 recovery mode is, when you need to use it, how to reboot into the recovery mode, and how to navigate and exit the recovery mode.
The Galaxy S20 recovery mode is identical on all 4 Galaxy S20 modes: Galaxy S20, S20+, S20 FE, and S20 Ultra. So this guide applies to all these phones.
What is Galaxy S20 recovery mode?
All Android phones and tablets come with a recovery mode. Galaxy S20 is not an exception. Android vendors may add or remove some features in the recovery mode.
On Galaxy S20, you can use the recovery mode to (as shown in the picture below):
- Wipe cache partition. This would wipe the cache partition to refresh apps without affecting your data on Galaxy S20.
- Reset (factory data reset) Galaxy S20. Some geeks may refer this to “wipe” the phone. You can erase all your data and return the phone to factory state. But it does not rollback the Android version or any updates.
- Update Galaxy S20 from ADB. If you want to sideload the update from your PC, you can do it using ADB. For example, you may manually update Galaxy S20 to Android 11 if you want
- Update Galaxy S20 from the micro SD card. You can also apply updates saved in the micro SD card.
- Reboot into bootloader (download mode). It allows you to enter download mode. For example, you want to install third-party recovery.
- Mount /system partition. It is supposed to let you edit and correct some errors in the system partition without rooting. But it seems it is not working.
- Run graphics test. It simply shows how the graphics (UI) like when the phone in different states, e.g., erasing, updating, optimizing apps. It has nothing to do with GPU or display.
- View recovery logs.
- Run locale test. Check the locale on the phone.
- Repair apps. This allows you to manually optimise apps (rebuild app cache and data cache).

This Galaxy S20 guide explains the 5 different shooting methods for Galaxy S20 and shows you how and when to use them.
As Samsung updates the Camera app with the Android OS (and One UI), you can find the Samsung Camera app on Galaxy phones with identical Android (and One UI) version is almost identical. Therefore, this guide applies to most Samsung Galaxy phones with Android 10 (and One UI 2.5), for example, Galaxy S10, Galaxy Note 10, and Galaxy Note 20.
Why do you need to consider shooting methods other than the shutter button for Galaxy S20 camera?
But occasionally, you may find it is not convenient to use the shutter button when taking selfies, especially when you want to include more people or the background and therefore you have to stretch your arm out.
For owners who get used to a point-and-shoot camera or DSLRs, a physical shutter button is always preferred. Unfortunately, all Android phone manufacturers are trying to minimize the number of physical buttons (and ports).
The good news is Samsung has maintained alternative shooting methods in their Galaxy phones. Therefore you can use volume keys, voice control, floating button, and palm to take photos and record videos.
What are the 5 different shooting methods for Galaxy S20 camera?
In the Galaxy S20 Camera app, you can use at least the following 5 shooting methods:
- Use the shutter button (default).
- Use the volume key.
- Use voice control.
- Use a floating shutter button.
- Show your palm (for selfies only).
We will explore them later (read on). By default, voice control and floating button are disabled on Galaxy S20.
When and how to use different shooting methods for Galaxy S20 camera?
As mentioned, two of the additional methods (voice control and floating shutter button) are not enabled by default; therefore, you need to enable them before you can use them.
Enable/disable different shooting methods for Galaxy S20 camera
You can manage, enable, and disable individual shooting methods in Galaxy S20 camera settings.
You can use various … Read the rest
You can use Galaxy S20 power mode to balance the performance and battery life based on your needs and habit.
This Galaxy S20 guide explains the importance of using the proper power modes on Galaxy S20, what are the 4 power modes on Galaxy S20, when and how to use each of these four power modes. The guide also shows you how to manage, customize, and limit battery usage (and background activities) for individual apps from app power management and application managers.
Samsung adopted almost identical power modes (power-saving modes) on all Galaxy Phones with Android 10. So, in addition to Galaxy S20, Galaxy S20+, Galaxy S20 Ultra, and Galaxy S20 FE, this guide also applies to most of the recent Galaxy phones, including all variants of Galaxy S10, Galaxy Note 20, and Galaxy Note 10.
Why is Galaxy S20 power mode important to balance performance and battery life?
Most of Galaxy S20 owners expect the phone worked when they want to use it. Running out of battery can be very disturbing nowadays, especially if you pay more than $1000 for the gadget.
Unfortunately, current Li-ion battery technologies still pose a hard limit on the battery capacity given the limited available space in the phone and possible and safety considerations.
So, one way to extend battery life so that you have enough battery before you can access a charger is to “save ” battery, i.e., reducing or optimizing the usage of the battery.
Basically, it is not necessary to let the Galaxy S20 run at its peak performance. For more than 90% of owners of Galaxy S20, the phone offers more processing power than what you need.
Even for heavy gamers, the high processing power is only needed when you play some large games. You do not need to keep the phone running in its peak state all the time.
Power mode in Galaxy S20 lets you balance the performance and battery life.
What are the 4 power modes on Galaxy S20?
On Samsung Galaxy S20, there are 4 power modes:
- Optimized (default).
- High performance.
- Medium power saving (aka, power saving)
This Galaxy S20 guide explains what Galaxy S20 Assistant Menu is, what it can do, how to enable, use and customize it, and how to use Assistant Plus to get even more from the Assistant Menu on Galaxy S20.
As Assistant Menu is more or less universal on all Samsung Galaxy phones, this guide applies to other Samsung Galaxy phones as well.
What is Galaxy S20 Assistant Menu?
Samsung Galaxy S20 Assistant Menu, a semi-transparent floating button overlayed on the phone screen, was initially designed for owners who need assistance for motor control and other physical impairments.
But it has been used by many seasoned Samsung phone owners to get faster access to some functions and features.
You may find the Assistant Menu very handy if you get used to it. It is more than an accessibility feature: it is also a productivity feature.
What can Samsung Galaxy S20 Assistant Menu do?
With Galaxy S20 Assistant Menu, you can:
- Access navigation buttons regardless of the navigation method (navigation gestures or navigation buttons) you are using.
- Access power button option (power menu). You can power off or restart the phone without using the power button (side key). You can also invoke emergency mode or lockdown mode for Galaxy S20. You may use it to power off the phone, then boot into Galaxy S20 safe mode or Galaxy S20 recovery mode. Please refer to this guide on how to enable and activate Galaxy S20 lockdown mode.

This Galaxy S20 guide explains why you should manage location services on Galaxy S20, how to turn on and turn off location services, how to manage location services for individual apps, and how to hide or remove location info when sharing photos through Google Photos or Samsung Gallery app.
As privacy settings (including location services) are almost identical on all Galaxy phones with Android 10, this guide applies to not only Galaxy S20 phones (including Galaxy S20, S20+, S20 Ultra, and S20 FE) but also Galaxy S10, Galaxy Note 10, Galaxy Note 20, Galaxy S9, and Galaxy Note 9.
Why is it important to manage location services on your phone?
For most phone owners, the location info is part of the critical private data. It reveals your whereabouts. It reveals your movement path and history. Smart guys or some AI apps can even figure out what you were doing based on the location information.
Of course, you do not want spammers, scammers, and bad guys to get such information.
Even for close friends or family members, occasionally, you may be reluctant to share such sensitive information.
But you cannot just turn off location services on Galaxy S20. Many apps need the info to function properly.
For example, most banking apps require location info for any transactions. Some shopping apps may also demand such info to reduce fraud. Of course, location-based apps or games, like Pokemon Go, Google Maps, or the weather widget on Galaxy S20 Home screen, rely on your location info to provide functions or services.
So, it is important to manage location services on Galaxy S20 so that only apps that genuinely require location info get the access. Other apps will be limited for accessing such info.
How to turn on and turn off location services on Galaxy S20?
You can categorically turn off location services on Galaxy S20 in Settings — Location, as shown in the screenshot below (marked as 1).
In this case, some apps, for example, the camera app, will remind you that the location is not available and ask you to enable it.
Please note once you turn off the location service, no apps can get the location info … Read the rest

What are home screen panels on Galaxy S20?
Each page of the Galaxy S20 Home screen is usually called a panel. So, home screen panels are just “pages” of your Galaxy S20 Home screen.
By default, when you unlock Galaxy S20, you will go to the home panel (read on) of Galaxy S20 Home screen (or last opened app).
Among all Galaxy S20 home screen panels, the following items are identical on all pages:
- Status bar.
- Favourite tray.
- Edge screen handle.
- Home screen panel indicator.
- Navigation buttons (if you are using buttons, instead of navigation gestures)
You need to use multiple home screen panels to accommodate:
When you put the apps on the Galaxy S20 Home screen, you can access them quickly without navigating to the Apps screen.
For widgets, you can only use them on the home screen.
Besides, on Galaxy S20, Samsung Daily (Bixby Home) always occupies the leftmost panel. You may follow this guide to hide or disable Samsung Daily (Bixby Home) on Galaxy S20. Please note, there is no way to remove it unless you root the phone or use other launchers.
What is the “home” panel of Galaxy S20 Home screen?
Because there are multiple home screen panels on Galaxy S20, you need to designate one as the “home” of the Galaxy S20 Home screen.
By default, the panel next to Samsung Daily (Bixby Home) is assigned as the “home” of Galaxy S20 Home screen. Of course, you can assign any panels (pages) as the home of the home screen panels.
The role of this panel is to represent the end … Read the rest
This Galaxy S20 guide explains what Do Not Disturb (DND) on Samsung Galaxy S20 is, how to enable and disable it on-the-fly, or based on predefined schedules, how to customize Do Not Disturb on Samsung Galaxy S20 so that you can allow specific contacts to reach you and certain apps to alert you.
The DND feature is common on most Galaxy phones. So this guide applies to not only Galaxy S20 but also other Samsung Galaxy phones with Android 10, for example, Galaxy S10, Galaxy Note 20, Galaxy Note 10, Galaxy S9, and Galaxy Note 9.
What is Do Not Disturb?
Android Marshmallow (Android 6) introduced the Do Not Disturb to help users limit interruptions from the phone and therefore improve productivity.
Over the last a few Android releases, Google fine-tuned this feature to make it easy to understand and easy to use.
Basically, on Samsung Galaxy S20, Do Not Disturb mode allows you to filter interruptions so that:
- Only some contacts can ring you.
- Most notifications are silenced.
- You can choose to hide specific or even all notifications.
- You can manage an exception list.
Please note, Samsung removed some Do Not Disturb features found in the stock Android, for example,
- You cannot trigger DND automatically based on calendar events. In most other Android phones, you can add event-based rules to turn on DND automatically.
- You cannot allow apps to overwrite DND.
So, do not assume Do Not Disturb on Samsung Galaxy S20 is identical to many non-Samsung Android phones.
How to enable and disable Do Not Disturb on Samsung Galaxy S20 on-the-fly?
In addition to turning on/off Do Not Disturb automatically (read on), there are a few different ways to enable or disable Do Not Disturb on Samsung Galaxy S20 on-the-fly.

This Galaxy S20 accessories guide explains how Sandisk Ultra Dual Drive USB work on Galaxy S20 and computers, when you may need this thumb drive, how to mount, unmount and access Sandisk Ultra Dual Drive USB Type-C on Galaxy S20, S10, S9 and S8, and when you should use the companion Memory Zone app and when not.
This is a continuation of this post which shows how to use the external USB drive on Galaxy S8, S9, S10, and S20 and explains the limitations and caveats of using a USB thumb drive. In this post, we focus on a specific product: Sandisk Ultra Dual Drive USB Type-C. It is one of the most reliable dual USB thumb drives that work on both PC and smartphones.
A brief review of using thumb drives and portable drives on smartphones
Traditionally, a USB device can be a master (host) or a salve (peripheral). When using a smartphone as a USB device, traditionally, the smartphone will be a slave device. For example, when you connect Galaxy S6 to the PC, it will be shown as a storage device. You cannot access the PC storage from the phone.
USB OTG (USB On-The-Go) standard allows a device to perform both master and slave roles.
To use USB accessories or peripherals (for example, USB Ethernet, USB MIDI) on the smartphone (which becomes a USB host), you need to meet two requirements:
- The smartphone must support USB OTG. Most Android phones, including Galaxy phones, support USB OTG.
- You need to use a USB OTG cable (or a USB OTG adapter). Some USB peripherals may have proper connector already. In this case, you do not need a cable or an adapter.
So, it is a bit complicated to use a thumb drive on the phone with a micro USB port. If the phone does not support USB OTG, then you cannot use it at all.
USB-C (USB Type C) dramatically simplifies it.
In USB -C specifications, the smartphone just needs to support the dual-role port (DRP). Then all USB accessories with a USB-C connector/port can be paired to the phone as a slave device. So, you can use the USB … Read the rest
This Galaxy S20 guide explains how to set and customize Galaxy S20 ringtones for each SIM card (if you are using two SIM cards) without installing any third-party apps, and how to customize ringtone for individual contacts so that you can “hear” who is calling when the phone rings.
This guide works on not only all Galaxy S20 (Galaxy S20, 20+, and S20 Ultra), but also all Galaxy phones with Android 10, including Galaxy S10, Galaxy Note10, Galaxy Note 20, Galaxy S9, and Galaxy Note 9.
When do you need to change the ringtone on Galaxy S20?
The default Galaxy S20 ringtone can cause confusion when there are a couple of Samsung phone users in the same room because most Galaxy phones use the same default ringtone.
So, in this case, it is wise to change the default ringtone to something else.
Sometimes, you may want to know who is calling without looking at the phone. Especially, you don’t want to miss some calls from a few important contacts. A customized ringtone for individual contact can solve your problem.
Some owners of the dual SIM versions of Galaxy S20 may use the two SIM cards (including eSIM) for different purposes. Of course, you may want to set a memorable ringtone for each SIM card so that you can hear which SIM card is called.
In short, you may consider to change or customize Galaxy S20 ringtone:
- To distinguish your phone calls from others in the room.
- To know who is calling you, just from the ringtone.
- To know which SIM card is called without looking at the phone.
Galaxy S20 allows you to choose from many pre-installed ringtones, or select your own music or audio files.
How to set Galaxy S20 ringtone for each SIM card?
You may follow these steps to change Galaxy S20 ringtone for individual SIM card.
Step 1: Open Galaxy S20 Settings
You can open Galaxy S20 setting in many different ways, for example:
- Tap the Settings app icon on Galaxy S20 Home screen or apps screen.

This Galaxy S20 camera guide explains how to access different Galaxy S20 camera modes, how to add frequently used camera modes to the preview screen so that you can access them quickly. A detailed explanation of all Galaxy S20 camera modes and their usages concludes this guide.
Although the three models of Galaxy S20 phones differ significantly in camera specs, the camera modes on Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra are actually identical. So this guide applies to all these three Galaxy S20 models.
How to access Galaxy S20 camera modes?
By default, when you open the camera app (including using Galaxy S20 camera quick launch), you are in the Photo mode (aka auto mode). This is the default Galaxy S20 camera mode.
Please note, if you open the camera again shortly after you closed it, or from the Recents screen, it may start with the last used camera mode depending on whether the process is stopped completely or not.
By default, there are four buttons. Three of them are for single-take camera mode, Photo mode, and video mode, respectively. The last one is the More button.
You can tap the More button to reveal all other available Galaxy S20 camera modes.
To access or use any of the Galaxy S20 camera modes, you simply tap on the mode. Galaxy S20 camera will change the camera mode to the tapped one instantly.
You can then take photos using that camera mode.
Please some Galaxy S20 camera modes are for the rear camera only. If you choose that mode, Galaxy S20 will switch to the rear camera immediately without warning if you are using the front-facing camera. Unlike that in previous Galaxy phones, Galaxy S20 does not grey out inapplicable camera modes for the front camera.
List of Galaxy S20 camera modes
By default, as shown in the screenshot above, there are 13 Galaxy S20 camera modes (excluding the burst mode):
- Photo mode (auto mode).
- Single-take mode.
- Video mode.
- Pro Mode (rear
You may also want to use one of the three Galaxy S20 sound modes in different scenarios to allow or mute all ringtones and notifications.
This Galaxy S20 guide explains the volume slider and how to use it to adjust volume for media, ringtones, notification tones, alarms, and system sound, how to use Galaxy S20 Settings to set sound modes, adjust the volume, and turn on /off some system sound.
Use Galaxy S20 volume slider to adjust volume for media, ringtones, notifications tones, and system sound
We all know we can use the volume keys to adjust the volume for media when playing music or video.
But when you are not playing any media, what happens if you press the volume key (volume up or volume down) on Galaxy S20?
It actually shows the volume slider. By default, it adjusts the volume for the ringtone. Of course, you can change this behaviour (read on)
On most of other Android 9 and 10 phones, the volume keys always adjust the media volume. Google removed the volume slider on the Android Pie (Android 9) in stock Android. But Samsung has kept the similar volume slider on all Galaxy phones for many years (since Android 4.0).
So, this guide only applies to Samsung phones, not other Android phones.
Galaxy S20 volume slider
As shown in the screenshot below, you will see the volume slider once you press volume down or volume up key.
Tap the down arrow to expand it.
In the expanded Galaxy S20 volume slider, you can control and adjust the volume for:
- Notifications (notification tone).
- System sound.
- Bixby voice.
Please note, you cannot adjust alarm volume in the volume slider. The volume for each alarm needs to be set up individually in the Clock app.
Adjust volume and mute Galaxy S20
You can drag the slider to the right side to increase the volume and left to decrease. If you drag the slider all the way to the left, you are essentially mute that sound.
You may also tap the icon on the left side to mute that sound quickly. For example, you can tap the ringtone icon to immediately mute ringtone. If you tap it again, the volume will be reset … Read the rest
Because the in-display ultrasound fingerprint reader on Galaxy S20 ( and S10) is hard to use and is slow, many Galaxy S20 owners have to use face recognition to unlock the phone and find that face recognition (face unlock) is faster than the fingerprint.
This Galaxy S20 guide explains what Galaxy S20 face recognition is, how to use and manage face recognition to unlock Galaxy S20, how to register your facial features for face unlock, and limitations of Galaxy S20 face recognition.
Galaxy S20 face recognition (face unlock) works identically on Galaxy S20, S20+, and S20 Ultra. So this guide applies to all of these three models.
What is Galaxy S20 face recognition (face unlock)?
In addition to using a PIN or password, you can use your biometrics to unlock Galaxy S20 (and other Android phones as well).
Galaxy S20 implements two biometrics features:
- Facial recognition.
Please note, Samsung stopped using (the most promising) iris scanner since Galaxy S10. You can find the iris scanner on Galaxy S8, S9, Note 8 and Note 9.
So, you can use your fingerprint and face to unlock Galaxy S20 if you want. By default, both fingerprint and facial recognition is not enabled.
Android included face unlock since Android 4.0 (Icecream Sandwich). Of course, it is less accurate than a fingerprint reader. Prior to Android Nougat (Android 7.0), it is easy to fool the phone with a photo.
In recent releases, Android has greatly improved facial recognition. It is fast enough so that you do not need to wait too long. It is accurate enough so that you cannot cheat it with a photo.
Of course, the face unlock on all Android phones is still considered as “less” secure than the fingerprint.
When Samsung ditched the iris scanner (and the intelligent scan), Samsung did NOT add an IR camera. So, on Galaxy S20, face unlock purely relies on the selfie camera. It is NOT comparable to Apple Face ID.
You may consider the Galaxy S20 facial recognition if you need an alternative to the inferior in-display fingerprint scanner.
Why is Galaxy S20 face recognition (face unlock) important?
As mentioned, in most Android phones, the traditional fingerprint reader works very well. You just put your finger on the reader, and it can wake … Read the rest
This Galaxy S20 guide explains what Galaxy S20 dark mode is, how to use and customize the dark mode on Galaxy S20, and how to force all apps to use dark mode on Galaxy S20.
Galaxy S20 dark mode works identically on Galaxy S20, S20+, and S20 Ultra. So this guide applies to all these three Galaxy S20 phones.
What is Galaxy S20 dark mode?
Galaxy S20 dark mode turns on a dark theme at the system level to alleviate eye strain, especially under low-light conditions. In the past, it was called night mode sometimes.
So, essentially, Galaxy S20 dark mode is the dark theme in other Android phones noticeable improvements.
The dark theme will try to use dark (black or grey) background and white text. This usually makes your eyes more comfortable when staring at the screen, especially when the light condition is not good.
Individual app developers may choose to implement the Android dark theme, or ignore it, or implement their own dark theme. So, by default, some apps may ignore the dark mode. In Android 10, you can force all apps to use the Galaxy S20 dark mode (read on).
One beneficial side-effect of applying Galaxy S20 dark mode is noticeable power saving (without changing Galaxy S20 power mode). Because Galaxy S20 uses super AMOLED. The black pixels consume almost no power. So, when you switch to the dark background, the screen will utilize less power. For most owners, power saving is noticeable, and it is helpful to extend the battery lifespan slightly.
For most Galaxy S20 owners, there are three benefits of turning on the dark mode on Galaxy S20:
- Alleviate eye strain.
- Save battery.
- Aesthetic (depending on individual owners). Some users prefer a white (light) background, and others may prefer the black (dark) background.
You can enable or disable Galaxy S20 dark mode at any time manually, or use it automatically based on your schedule.
How to enable and disable the Galaxy S20 dark mode?
By default, the dark mode is not enabled on Galaxy S20. There are at least … Read the rest
This Galaxy S20 guide explains what Galaxy S20 safe mode is, how to enter the Galaxy S20 safe mode, use the safe mode, and exit the safe mode on Galaxy S20.
Because the safe mode is one of the standard Android features, this guide applies to not only Galaxy S20 models (Galaxy S20, S20+, S20FE, and S20 Ultra) but also other Android phones including Galaxy S10, Galaxy Note 10, Galaxy S9, and many others.
What is Galaxy S20 safe mode?
Galaxy S20 safe mode is a special mode with all third-party (non-preinstalled) apps and services suspended temporally. All system settings and pre-installed app settings and data can be used normally.
So, safe mode does not reset your Galaxy S20 to the factory state. And therefore, it is “safe” for your data.
Of course, the real meaning of “safe” is that your Galaxy S20 is shielded from any third-party apps and services.
Under Galaxy S20 safe mode, you can figure out whether some weird issues are caused by any third-party apps, or pre-installed apps (and system settings). Normally, you should try safe mode before trying to wiping the cache partition in the Galaxy S20 recovery mode.
Safe mode is a built-in feature of Android. You can actually find it in almost all Android devices. And it works almost identically on all Android devices.
In a nutshell, Galaxy S20 safe mode allows you to check whether a problem is caused by third-party apps or services installed by you, or caused by system and pre-installed apps.
How to boot into Galaxy S20 safe mode?
There are at least two ways to boot the phone into Galaxy S20 safe mode.
Method 1: Use the Power Button menu (safe method)
This method works if your Galaxy S20 can still boot up to at least the lock screen.
Step 1: Hold the side key to access the Power-off menu
After the phone is booted to Galaxy S20 lock screen, or to Home screen, you can hold the side key (as illustrated below) for about 2-3 seconds, to call out the power-off menu (aka power menu, power button options).
But many Galaxy S20 owners are a bit confused on choosing the correct camera lens and set the proper zoom levels.
This Galaxy S20 guide explains the differences among the three main (rear) cameras, the link between zoom and camera lenses, how to choose different camera lenses, and how to zoom in and zoom out properly.
In this guide, we mainly use the Galaxy S20 Ultra rear cameras as an example. When there are any differences, we will highlight whether the feature is for Galaxy S20 Ultra, or Galaxy S20 (and S20+). All camera software features on three Galaxy S20 models are identical, although Galaxy S20 Ultra has better hardware specs for the primary wide-angle camera and the telephoto camera.
What are the different camera lenses on Galaxy S20?
Besides the depth sensor camera on Galaxy 20+ and S20 Ultra, on all three models of Galaxy S20 phones, there are three camera lenses for different purposes:
- Wide-angle camera.
- Ultra-wide-angle camera.
- Telephoto camera.
Galaxy S20, Galaxy S20 FE, and Galaxy S20+ share the identical hardware of these three camera lenses. Galaxy S20 Ultra has an upgraded camera system. But the camera app is identical on all these phones. You can also use different shooting methods as well on all of these phones.
The 12MP (or 108MP on Galaxy S20 Ultra) wide-angle camera is the primary shooter. By default, you will take photos and record videos (except 8K videos) with this camera lens. Of course, you can choose other lenses if you want (read on).
On Galaxy S20 Ultra, you can choose to save the pictures as 12MP (at the aspect ratio of 4:3) after combining pixels, or as 108MP (which take s far more storage). Usually, you should save the photo as normal 12MP in indoor or low-light conditions. You may consider the108MP option when lighting is excellent (e.g., outdoor in sunny days).
The 12MP ultra-wide-angle camera is identical on all three Galaxy S20 models.
Many Galaxy S20 owners customize Galaxy S20 wallpapers once they migrate the data from the old phone and finish the initial setup.
But most owners may not be aware that Galaxy S20 wallpapers are not just a few pictures. You can also use videos, random photos, or Samsung curated photo packs as Galaxy S20 wallpapers.
This Galaxy S20 guide explains the differences between Galaxy S20 Home screen wallpapers and lock screen wallpapers, the advanced features of Galaxy S20 wallpapers (multi-pack, live wallpapers, video wallpapers, dynamic lock screen, Samsung Global Goals), and how to customize Galaxy S20 wallpapers with these advanced features.
The difference between Galaxy S20 lock screen wallpapers and home screen wallpapers
Samsung made some changes on the wallpapers on the home screen and lock screen on Galaxy S20. Other Samsung Galaxy phones with Android 10 (e.g., Galaxy S10, Galaxy Note 10) also have identical wallpaper settings.
The major differences between Galaxy S20 lock screen wallpapers and home screen wallpapers include:
- Live wallpaper is NOT supported on Galaxy S20 Home screen. The infinity effect (and motion effect) of wallpapers does not work on Galaxy S20 Home screen either.
- Multi-pack is NOT supported on Galaxy S20 Home screen.
- Random photos (photo slideshow) works on Galaxy S20 lock screen only.
- Videos can be assigned for wallpapers on the lock screen only.
- The Dynamic Lock is for Galaxy S20 lock screen only.
In a nutshell, without using a third-party app, you can only use one static image for the Galaxy S20 Home screen wallpaper. For the lock screen, you have many options.
If you just migrated from an old Galaxy phone, you may find the live wallpapers are missing from the Galaxy S20 Home screen.
5 advanced features of Galaxy S20 wallpapers on the lock screen and home screen
Samsung tried hard to improve the wallpapers on the lock screen. But at the same time, they keep removing features from the home screen wallpapers. It is a very confusing move.
Most of the advanced features of the Galaxy S20 wallpapers discussed here are mainly for the Galaxy S20 lock screen. Only the dark mode for wallpapers is for both the Home screen and lock screen.
Here are the five (5) noteworthy advanced features of Galaxy S20 wallpapers.
#1. Dark mode for Galaxy S20 wallpapers
Galaxy S20 dark mode is excellent. It may significantly reduce your eye … Read the rest
This guide shows you how to change the app icon shape on Galaxy S20, the available shapes, the limitations and caveats for the new icon shapes.
Samsung added the icon shape customization feature in all Galaxy phones with Android 10. So, this feature is also available on other Galaxy phones including Galaxy S10, Galaxy Note 10, Galaxy Note 9, Galaxy S9, and a few other models.
Update: In Android 11 update (with One UI 3.0), Samsung removed the option of customizing icon shape. You have to use third-party themes or launcher if you do not like the squircle icons.
The limitations and caveats of changing icon shape on Galaxy S20
Before starting to change the icon shape on Galaxy S20, you should be aware of the following 5 caveats and limitations.
#1. The icon shape change is limited to app icons.
The icons in the quick settings panel, or other system UI, will not be affected.
#2. Most of Samsung apps do not change icon shape.
Almost all Samsung apps (e.g., Phone, Messages, Gallery, Camera) were shipped with only one icon shape: squircle.
So, the icon shape will NEVER change for these apps on Galaxy S20.
#3. Some third-party apps may not change the icon shape for some shapes.
Except for apps from Google, some third-party apps may not support some icon shapes.
For example, a lot of third-party apps do not support the teardrop shape.
Please note, whether an app icon shape is supported or not is defined in the app (by the app developer).
#4. You need to enable developer options to change the icon shape on Samsung phones.
On Samsung Galaxy phones with Android 10, app icon shape customization is hidden in the theming section of Galaxy S20 developer options.
So, you need to enable the developer options before you can customize the icon shape.
#5. You need to reboot the phone to see the new icon shape.
Although most owners do not need to change mobile networks settings on Galaxy S20, it is crucial to understand the options for the mobile networks so that you can solve some mobile network related issues when it happens suddenly.
This Galaxy S20 guide explains the mobile networks settings on Galaxy S20, shows you when and how to use them, and illustrates how to check the mobile network status and SIM card status on Galaxy S20.
Most of the mobile networks settings on all three Galaxy S20 models are almost identical. So, this guide applies to all Galaxy S20 phones (Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra).
When do you need to change the mobile networks settings on Galaxy S20?
The default mobile networks settings on Galaxy S20 are usually sufficient for most owners. They may never touch the mobile network settings at all.
But from time to time, due to some carrier’s configurations, or some software glitches, you may have to change or check the mobile networks settings on Galaxy S20.
Here are a few example scenarios when you need to head to the mobile networks settings on Galaxy S20
#1. Enable/disable data roaming
Data roaming can be costly if you do not have a particular roaming plan with your carrier.
By default, data roaming is disabled. But once you enabled, it will be on until you disable it. When your phone is roaming, you should see the roaming icon (R added to the signal strength), as explained in here.
#2. Add or edit APN settings
APN (Access Point Name) is essential for mobile data connections. In addition to internet access, MMS also replies on correct APN settings.
If you need to edit or add APN settings, you need to access Galaxy S20 mobile networks settings. Read on.
#3. Select a network operator (especially when roaming)
If your SIM card can use more than one mobile network, you can manually choose one. This also has to be done under mobile networks settings on Galaxy S20.
When your Galaxy S20 is roaming, your carrier may have multiple local roaming partners. Some may offer better coverage. Some may offer a better connection. Some may offer a lower roaming price.
Understand mobile networks settings on Galaxy S20
You can access Galaxy S20 mobile networks settings from Galaxy S20 Settings.
This Galaxy S20 guide explains how the app shortcuts on Galaxy S20 lock screen work, how to manage, customize and use the app shortcuts on the lock screen, how to use the floating button for app shortcuts.
App shortcuts are available on all Galaxy S20 models: Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra. So, this guide applies to all these three Galaxy S20 models.
How do app shortcuts on Galaxy S20 lock screen work?
As explained in this guide, on Galaxy S20 lock screen, by default, there are two app shortcuts (Phone app and Camera app, by default) on the two bottom corners.
There are no security issues with the app shortcuts on the Galaxy S20 lock screen.
Most apps will work only after you unlock Galaxy S20. Only selected apps will work without accessing your data and without unlocking Galaxy S20.
Your data are always safe. They can only be accessed after you unlock the phone. There is no exception.
So, the app shortcuts on Galaxy S20 lock screen work in different ways depending on the app shortcuts you put there:
- Without restrictions. For apps that do not access any data, they can work normally. For example, you can use Flashlight or Do Not Disturb without any restriction on the lock screen.
- With restrictions. For selected apps, including Phone app, Camera app, they can run in a restricted mode. For example, the Phone app on the lock screen can only be used for emergency calls. The camera app can only be used to take photos or record videos, and it can only access photos or videos taken in that session. Of course, you can use all Galaxy S20 camera modes and change some camera settings.
- Unlocking the phone is required. For most apps, you need to unlock the phone to continue the app.
This Galaxy S20 camera guide shows you why you get the mirrored photo by default, how to change the default setting to avoid mirrored selfies on Galaxy S20, and how to edit (flip) the existing mirrored photos on Galaxy S20 with the Gallery app.
Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra share the identical front camera settings, so, this guide applies to all these 3 Galaxy S20 models although we only use S20 in the text.
Why do I get mirrored photos (selfies) on Galaxy S20?
When using the Galaxy S20 front camera, on the preview screen, you will see yourself (and everything) like using a mirror.
All smartphone cameras are designed and coded to work in this way. It is not by a random mistake.
It is actually related to the visual perception of seeing ourselves. Most of the time, we see ourselves through mirrors. Therefore, our brains train us to recognize such images. When we are in a video call, we will perceive our “flipped” video as natural and usual.
If you give a flipped and non-flipped selfie of a person to himself, very likely, he will tell you the flipped one is “more” natural until he notices the reversed (and therefore strange) text.
When Kyocera Visual Phone VP-210 first introduce the front-facing camera in 1999, it was mainly designed for video calls, although it can take photos as well.
But if you look at the mirrored photos carefully, you will notice it is hard to read the text, whose direction is reversed. It is similar to the text in an ambulance car. The text in the ambulance car is mirrored so that drivers can read it correctly from the rearview mirror and give way to it.
Anyway, it is a standard implementation in the industry to flip front-camera photos.
Of course, as the photos or selfies are just mirrored (flipped), you can easily flip them back.
And most smartphones offer the option for you to flip back the mirrored photos when saving them.
How to avoid mirrored photos (selfies) on Galaxy S20?
As mentioned, you can flip the mirrored photos on Galaxy S20 (read on). But sometimes, many users may want to avoid the flipped photos when tapping the shutter button.
Please note, there is NO way … Read the rest
This Galaxy S20 guide explains when you need to enable developer options, how to enable and use the options, and a complete list of Galaxy S20 developer options. Examples of using Galaxy S20 developer options to add developer tiles to the quick settings panel, and to customise the default USB configurations are also included.
Please note, in this guide, Galaxy S20 refers to all three Galaxy S20 models: Galaxy S20, S20+, and S20 Ultra, because the developer options on these three phones are identical.
What are Galaxy S20 developer options?
Traditionally, Android hides with some special additional features for developers so that they can test their apps on any supported Android devices while normal users may never notice such features.
Some beta, experimental, and even legacy features were also hidden in Andriod devices. Google has to make sure that such features are visible only to users who are aware of such features,
Developer options in Android devices is a collection of these features. Some Android vendors may add or remove a few entries on their devices.
Galaxy S20 developer options are very similar to those in stock Android 10. Only a few new entries were added by Samsung.
When do you need to enable and access Galaxy S20 developer options
If you are an Android developer, surely, you can use the developer options to test apps on Galaxy S20, instead of the virtual machines of Pixel or Nexus devices.
Samsung is the largest Android vendor. So, it is necessary to test apps on the latest Galaxy phones.
Besides developers, many Android enthusiasts may also try some experimental or beta features of Android 10 on Galaxy S20.
For typical Galaxy S20 owners, you may still occasionally need to enable and use the developer options to access certain features. For example:
- You want to force all apps to be resizable so that you can use it in both pop-up view and split-screen view.
- You want to force all apps (except system apps and pre-installed apps) to use the micro SD card. As explained in this guide, many app developers
This Galaxy S20 guide explains when you need to lock the Galaxy S20 Home screen layout, how to do it, and the side effects of locking the layout of Galaxy S20 Home screen.
Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra share the same launched and the identical home screen settings. So this guide applies to all Galaxy S20 phones, although we use Galaxy S20 in the guide.
Besides, because locking the home screen layout is a feature of Samsung’s One UI launcher, you can find and use this feature on all other Galaxy phones with One UI, including, Galaxy S8, S9, S10, Note 8, Note 9, and Note 10, as well.
When do you need to lock the Galaxy S20 Home screen layout?
Although Galaxy S20 makes the curved part of the screen less obvious, it is still a big distraction and a big waste (of usable screen space).
So, it is not uncommon that you may get surprised at the “new” Galaxy S20 Home screen: some app icons disappear, some app icons moved.
In the worst scenario, you may uninstall some apps inadvertently from the Galaxy S20 home screen when the phone is in your pocket or bag.
You can minimize such accidental modifications by locking the home screen layout.
How to lock the Galaxy S20 Home screen layout?
By default, the layout of the Galaxy S20 Home screen is not locked.
For example, when you install new apps on Galaxy S20, the app icon (a shortcut to the app) will be added to the Galaxy S20 Home screen.
To lock the Galaxy S20 Home screen, you may follow the following steps.
Step 1: Enter the edit mode for Galaxy S20 Home screen
The quickest way to access Galaxy S20 Home screens settings is through the edit mode.
But the support of the micro SD card on Galaxy S20 is different from that in stock Android.
This Galaxy S20 guide explains the supported micro SD card features on Galaxy S20, the requirements of using a micro SD card, how to add and manage the SD card, how to move apps to the micro SD card and how to mount and unmount the SD card on Galaxy S20, and how to choose an SD card for Galaxy S20.
In this guide, Galaxy S20 refers to Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra.
Does Galaxy S20 support adoptable storage so that I can use the micro SD card as internal storage?
No, Galaxy S20 does not support the adoptable storage. But Galaxy S20 does support moving apps to the micro SD card.
Since Android Marshmallow (Android 6), Google introduced the adoptable storage to let you use the micro SD card as internal storage. It essentially increases the internal storage capacity at a far lower price.
Of course, due to performance limitations of the micro SD card, most flagship Android phones do not support the adoptable storage. Some, for example, Google Pixel phones, do not have a micro SD card slot at all. The adoptable storage support can be found in many middle-range and budget Android phones.
The other option is to use the micro SD card as portable storage, where you can save your own files, for example, your music or media collections. Apps can also request to access the portable storage to download and save large files. The “flagship” (usually means expensive and overpriced) Android phones with a micro SD card support, often only support the portable storage.
Unlike other Android vendors, Samsung chose a proprietory way to support micro SD card. It is somewhere between adoptable storage and portable storage.
- You cannot format the micro SD card as the internal storage on Galaxy S20.
- But you can move most apps to the micro SD card if you want.
Actually, this is a better implementation than the adoptable or portable storage, because
- The micro SD card is portable. You can share the media files on the SD card on any
This Galaxy S20 how-to guide explains what Samsung Galaxy S20 Home screen edit mode is, how to access this mode with two different gestures, and what you can do in the Galaxy S20 Home screen edit mode to customize Galaxy S20 Home screen.
The Galaxy S20 Home screen edit mode is identical on all three models of Galaxy S20. So this guide applies to Galaxy S20, S20+, and S20 Ultra.
What is Galaxy S20 Home screen edit mode?
The quickest way to customize the Galaxy S20 Home screen is to use the edit (customization ) mode.
Sometimes the home screen edit mode may be referred to the Home screen customization or settings page. But on Galaxy S20, Samsung added a dedicated Home screen settings page. In the Galaxy S20 Home screen edit mode, there is a shortcut to this home screen settings page.
Besides, after Android 5.0 removed the Widgets tab in the Apps screen, the only way to manually add widgets to the Galaxy S20 Home screen is through the Galaxy S20 Home screen edit mode.
You can imagine the Galaxy S20 home screen edit mode is a special page hiding behind the Home screen. You can quickly access it to customize the Galaxy S20 Home screen and change the home screen settings.
How to access Galaxy S20 Home screen edit mode?
You can access the edit mode of Galaxy S20 Home screen with two different gestures, as illustrated in the screenshot below.
Gesture A: Tap and hold (long tap) on the blank area
The gap between any two app icons is also a blank area.
Gesture B: Pinch on the Home screen
You can pinch over the home screen to enter the edit mode.
How to customize Galaxy S20 Home screen in the edit mode?
The purpose of the Galaxy S20 Home screen edit mode is for you to quickly customize the Home screen. For example, you can quickly disable (hide) the Samsung Daily on the Galaxy S20 home screen, or customize the … Read the rest
This Galaxy S20 guide explains the role of the display refresh rate on Galaxy S20, how to change the refresh rate on Galaxy S20, the limitations of the 120Hz refresh rate on Galaxy S20. Some questions you may have on this feature are also addressed.
The display refresh rate feature on three Galaxy S20 phones are identical. So, S20 in this refers to Galaxy S20, S20+, and S20 Ultra.
What are the 60Hz and 120Hz display refresh rate on Galaxy S20?
The display refresh rate measures the number of times per second the display can redraw the whole screen. So, the unit of the refresh rate is Hertz (Hz, 1/s).
For most smartphones, the display refresh rate is 60Hz. And it is good enough for most users.
Most videos have a frame rate of 24~30 fps (frames per second). Loosely, you can think one frame means one static image on the screen.
So, as long as the refresh rate is higher than the fps of the video, we say the display can handle the video. You can watch the video on such a display.
In reality, the 60Hz display refresh rate allows you to watch the video smoothly.
But some users, mainly gamers, may prefer a higher refresh rate to enjoy more realistic gaming experiences.
The hardware and the software on Galaxy S20 are capable of generating graphic output at very high speed, far higher than 60fps even at the full WQHD resolution.
So, some games can benefit from the high fps if the display can handle the output smoothly.
Galaxy S20 answers such demands with the 120Hz refresh rate display.
As mentioned, the 120Hz refresh rate is not for everyone. You will see the difference if:
- You are playing 60fps (or higher) videos.
- You are playing a few games that can handle/generate output at a rate higher than 60fps. Most games do NOT benefit from a high frame rate.
Anyway, as a new feature of Galaxy S20, the 120Hz refresh rate display (motion smoothness) may improve your experiences with a few games and videos.
How to set the Galaxy S20 display refresh rate?
By default, the Galaxy S20 display refresh rate is et at 60Hz. You can change it to 120Hz in the motion smoothness settings.
Please note, the 120Hz refresh rate is not … Read the rest
This Galaxy S20 guide explains what the faceWidgets are, how to customize the faceWidgets on Galaxy S20-, and how to access and use these widgets on Galaxy S20 lock screen and always-on display (AOD) screen.
As faceWidges are also available on other Galaxy phones with Android Nougat (7.0) or later, this guide applies not only to Galaxy S20 (S20, S20+, and S20 Ultra), but also other Galaxy phones including Galaxy Note 10, Galaxy S10, Galaxy S9, Galaxy Note 9, Galaxy S8, and Galaxy Note 8.
Update: Android 11 update for Galaxy S20 revamped the faceWidgets and renamed them as widgets. If you have updated your Galaxy S20 to Android 11, you may check this guide on how to access, use, and customise widgets on Galaxy S20 lock screen and AOD screen. This guide applies to Galaxy S20 with Android 10.
What is faceWidgets on Galaxy S20?
The FaceWidgets lets you get quick access to useful information on the lock screen and always-display screen without unlocking the phone.
Surely, Galaxy S20 faceWidgets is not a new feature. Samsung introduced faceWidgets on Galaxy S8.
Over the years, Samsung added Bixby routine and weather info the faceWidgets.
The purpose of faceWidgets is for you to quickly get some useful info from the Galaxy S20 lock screen (without unlocking the phone) and from the Galaxy S20 always-on display (AOD) screen (without waking up the screen).
On Galaxy S20, you can use the following five widgets on both the lock screen and AOD screen:
- Today’s schedule.
- Next Alarm.
- Bixby Routines.
- Digital wellbeing (only after your Galaxy S20 was updated to Android 11).
You can customize them by enabling/disable them individually or recording them.
But you cannot add your own widgets to the faceWidgets
How to customize faceWidgets on Galaxy S20?
On all supported Galaxy phones, faceWidgets is under the lock screen settings.
Enable and disable individual widgets
As shown in the screenshot below, in the Galaxy S20 Settings, tap Lock screen first.
In the Galaxy S20 lock screen settings page, as shown above, you can find the FaceWidgets entry.

Samsung debuted the single take camera mode with the release of Galaxy S20. It helps you take several photos and videos automatically to capture important moments.
This Galaxy S20 camera guide explains how Galaxy S20 single take camera mode works, the limitations of the single take camera mode on Galaxy S20, how to use this camera mode to take single take photos and videos, and how to manage photos taken in the Galaxy S20 single take camera mode.
Because Samsung has backported the single take camera mode to Galaxy S10 and Galaxy Note 10 in One UI 2.1 update, you can use this camera mode not only on Galaxy S20 (S20, S20+, and S20 Ultra), but also Galaxy S10 (S10, S10e, and S10+) and Galaxy Note 10 (Note 10, Note 10+).
In this guide, Galaxy S20 is used as an example. You can use the single take camera mode on all support phones.
How does the single take camera mode on Galaxy S20 work?
Galaxy S20 single take camera mode uses artificial intelligence (AI) to analysis the scene and takes up to 10 photos and up to 4 videos automatically for you in 3-10 seconds.
You can simplify the single take camera mode into the following three stages.
- It uses all available camera lens/sensors to take many photos and record a few videos with various settings based on the scene detected.
- It analyses all photos and videos taken.
- It outputs the best photos and videos (including GIF animations if appropriate).
In stage 1, Galaxy S20 camera uses scene recognition and optimization to get the “optimal” settings first. The primary camera, ultra-wide camera and telephoto camera are all used to take some snapshots.
In stage 3, the photos or video generated are usually not the “original” one. Some original photos may be merged and cropped to form a “final” photo. Panorama photos and GIF animations may also be created if Galaxy S20 thinks they are relevant to the scene. A few camera effects may also be applied to the output photos.
Anyway, the Galaxy S20 single take camera mode was designed to help you capture the important moments automatically with the optimal settings.
Can I use the single take camera mode on other phones (e.g., Galaxy S10 and Galaxy Note 10)?

Although it is usually a simple task to turn on or turn off Galaxy S20, it can be frustrating, especially when the phone hangs and you need to use Galaxy S20 urgently.
This Galaxy S20 guide shows you how to power on (turn on), power off (turn off), and restart (reboot) Galaxy S20, even when the phone hangs (non-responsive).
The guide applies to all three models of Galaxy S20: Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra.
Power on Galaxy S20 (turn on, power up)
When the phone is off, you can hold the Side key (see Galaxy S20 layout) to power on (turn on) Galaxy S20 normally.
Please note, Samsung combined the old Power key with the unpopular Bixby key as the Galaxy S20 Side key.
As shown in the Galaxy S20 layout, the Side key is located on the right side of the phone, below the volume key. There is no physical keys or buttons on the left side any more.
Please note, if you hold volume buttons and the Side key, then you may:
- Boot into Galaxy S20 recovery mode if you hold volume up button and the Side key.
- Boot into Galaxy S20 download mode if you hold volume down and the Side Key.
- Boot into Galaxy S20 safe mode if you hold the side Key, release the Side key and hold volume down key when you see Samsung logo.
Power off Galaxy S20 (turn off)
There is no hardware button (key) to power off Galaxy S20. If you hold the Side key, Galaxy S20 will reboot (restart), instead of powering off the phone. But sometimes, you need to power off Galaxy S20, e.g., when you enter a restricted area, or when you want to boot into Galaxy S20 recovery mode.
To power off Galaxy S20 gracefully, you need to use the software Power off button, which can be accessed in various locations on Galaxy S20.
Please note, if you power off Galaxy S20, you cannot receive calls from the phone. Text messages (SMS) will be saved by your carrier and delivered to the phone after you power on the phone and connect to the mobile network. You may check this guide on how to use SIM cards on Galaxy S20.

This Galaxy S20 how-to guide explains the requirements for you to unlock Galaxy S20 without a password or PIN, steps to unlock Galaxy S20 if you forget the password or PIN using Samsung FGind My Mobile, and how to remotely lock and secure your phone with Samsung Find My Mobile services.
In most regions, you can unlock Samsung Galaxy phones if you forget the password or PIN using Samsung Find My Mobile service. So, this guide applies to most Samsung Galaxy phones, including Galaxy S20, S10, Note 10, S9, Note 9, S8, Note 8, and other popular Samsung Galaxy phones.
Can I reset the password (unlock Galaxy S20) on Google Find My Device (Android Device Manager) if I forget the password or PIN on Galaxy S20?
No, Google removed the remote unlock and password reset features from Android Device Manager (now, Find My Device) in 2016.
So, if you forget the password or PIN on Galaxy S20, Google Find My Device can only help you erase (reset) the phone, i.e., factory data reset (FDR), or lock up the phone.
Google Find My Device will never unlock Galaxy S20, or reset the password/PIN. It can lock the phone (if it is unlocked) remotely. Some users confuse the “lock” and “unlock” feature in Google Find My Device.
Please note, the factory data reset will erase all of your data and settings. This is only useful if your phone is lost or stolen. You can reset Galaxy S20 in the recovery mode as well.
If your Galaxy S20 is still in your hands and you only forget the password or PIN for the lock screen, then probably it is not necessary to reset the phone.
Currently, for Galaxy S20 and other Samsung Galaxy phones, only Samsung Find My Mobile can unlock Galaxy S20 without a password or PIN.
The requirements to unlock Galaxy S20 when you forget the password or PIN
If you need to unlock Galaxy S20 and you forget the password or PIN, you need to meet the following requirements:
- The phone is online.
- You added your Samsung account to the phone.
- You enabled Find My Mobile on the phone. By default, it is
This Galaxy S20 guide explains what Galaxy S20 always-on display (AOD) is, the differences between AOD and lock screen, how to enable and customize AOD on Galaxy S20, and how to use AOD with Galaxy S20 clear view cover.
The always-on display (AOD) feature on all three Galaxy S20 models (Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra) is identical. This guide works identically on these three phones although Galaxy S20 is used in the guide.
What is Galaxy S20 always-on display (AOD)?
Galaxy S20 always-on display allows you to customize Galaxy S20 screen to show time, date, battery status, notifications, screen savers, faceWidgets, pinned image, today’s schedule after the screen times out.
Always-on display (AOD) is not new. But Samsung did remove some features from the Galaxy S20 always-on display (AOD).
For example, you cannot pin a note, or a memo, or a reminder, or a future calendar event on Galaxy S20 AOD screen, if you migrated to Galaxy S20 from older Galaxy phones.
Anyway, the Galaxy S20 always-on display was designed to show some useful info when it seats on the desk. You can quickly peek the time, notifications, or battery status on the screen without stopping your work.
By default, when the screen times out (no activity on the screen), the display will be turned off automatically to save battery and maximize the lifespan of the screen. For this reason, the maximum screen timeout on Galaxy S20 is 10 minutes.
The Galaxy S20 always-on display (AOD), if enabled, will turn on the screen without waking up the phone after the screen is turned off.
Because the AOD does not wake up Galaxy S20, it will not consume battery excessively. The added battery consumption is mainly for lighting up part of the screen. For Galaxy S20, the AMOLED display is very power efficient and does not consume power for black pixels.
So, Galaxy S20 AOD will only slightly affect battery life (screen-on time) on Galaxy S20.
The differences between Galaxy S20 always-on display (AOD) and the lock screen?

Why you may need to hide password on Galaxy S20 when typing it?
By default, the password or PIN field on Galaxy S20 will display *s or dots, instead of the actual characters, to protect your password or PIN from prying eyes.
But when you type the password or PIN on Galaxy S20, the last typed character will show briefly on the screen.
It was designed for you to check the typed the password or PIN.
But this could be a big concern when you need to type password or PIN in the crowded public places. For example, in the crowded subway, it is hard to prevent others from seeing your screen.
So, you may want to hide password on Galaxy S20 even when typing, i.e., make the password invisible when typing.
Please note, if you use a PIN to unlock the phone, you can hide the PIN and confirm PIN without tapping OK on Galaxy S20. But for the password, you can only hide it when typing, and you have to tap OK or enter to confirm.
How to hide password on Galaxy S20 when typing it?
As mentioned, by default, the last typed character of the password or PIN is visible on the screen briefly.
You can follow these steps to hide password on Galaxy S20 when typing.

The built-in Galaxy S20 screenshot toolbar can also further help you take screenshots for elongated pages automatically, edit, and share the captured screenshots efficiently.
This Galaxy S20 guide shows you the 4 easy ways to take a screenshot on Galaxy S20 without using any third-party apps and explains how to use the screenshot toolbar to take a screenshot for scrollable pages, edit, share, and add tags to the captured screenshot.
This guide applies to Galaxy S20, Galaxy S20+, and S20 Ultra, although we use Galaxy S20 in the text.
4 easy ways to take a screenshot on Galaxy S20
Taking screenshots on Galaxy S20 is not only easy but also fun. There are a few different ways to take a screenshot on Galaxy S20 without using any third-party apps.
In this guide, I will show you the four easiest ways to take screenshots on Galaxy S20, S20+, and S20 Ultra.
Hardware key method (Side key + volume down key)
In all Android devices, the built-in method of taking a screenshot is holding the power key and volume down key simultaneously.
On Galaxy S20, the Side key replaces the traditional power key.
So, the corresponding method of taking a screenshot on Galaxy S20 is to hold the Side key and volume down key simultaneously, as illustrated below (you may check Galaxy S20 layout on the location of the side key and volume key).
The only requirement is to hold the two keys simultaneously. It needs some practice if you are new to this method:
- If you get the volume adjustment bar (aka volume slider), it means you press the Side key too late.
- If you get the power button option (power-off menu), then it means you press the volume down button too late.
Anyway, you may try to hold the Side key slightly earlier than the volume down key.
Palm Swipe to capture
The funniest way to take a screenshot on Galaxy S20 is to swipe your palm over the screen, as illustrated below.
This method is a bit tricky. Your palm should “slightly” touch the screen.
When you unlock Galaxy S20 with a PIN, you can confirm PIN without tapping OK to unlock the phone directly to Galaxy S20 Home screen.
This Galaxy S20 guide explains why you may need to confirm PIN without tapping OK, then shows you how to enable and disable this feature. Some FAQs related to conforming PIN without tapping OK on Galaxy S20 are answered.
This feature is available in most Samsung Galaxy phones including all 3 models of Galaxy S20 (Galaxy S20, S20+, and S20 Ultra), Galaxy S10, Galaxy Note 10, Galaxy S9 and many others.
Please also note, this feature works only for screen lock type as a PIN. If you set the screen lock type as password, you always have to manually confirm the password.
Why do you need to confirm PIN without tapping OK on Galaxy S20?
By default, when you unlock Galaxy S20 with a PIN, you have to type the PIN, then tap OK on the keypad to confirm.
Many owners think this is “natural” because they have done this from day one of using a smartphone.
If you want to unlock the phone more quickly without tapping the OK to confirm the typed PIN, then the solution exists on Samsung Galaxy S20 and many other Galaxy phones.
In other words, you can just type the PIN and unlock the phone instantly. When typing, if the typed PIN matches the lock screen PIN, then Galaxy S20 will be unlocked automatically.
Obviously, this is a more efficient way to unlock the phone with a PIN.
Unfortunately, this feature is not enabled by default. You can enable it when setting up the phone, or you can enable and disable it at any time. Read on.
Of course, this feature is not for everyone. But it can be beneficial if you can confirm PIN without tapping OK for many Galaxy S20 owners.
If you need to unlock the phone faster.
Without tapping OK not only save you one tap but also save the time for you to switch from tapping to mentally confirm the PIN.
If you use a similar PIN on different devices, you can just use a PIN with different length.
It is a bad practice to use the identical PIN on all devices.
But if you use totally different PINs, it is a pain to remember all … Read the rest
This Galaxy S20 accessories guide explains the Galaxy S20 LED back cover unique features including mood lighting. LED icons, the camera LED icon, and camera timer countdown, and how to use and customize these features. Galaxy Friends features for Galaxy S20 LED cover are explained. A concise review of Galaxy S20 LED back cover is also included in this guide to help you decide whether you should get this cover or not.
The features of the LED cover on Galaxy S20, S20+, and S20 Ultra are identical, although the physical dimensions of the case for these 3 phones are different. So, in this guide, Galaxy S20 refers to Galaxy S20, S20+, and S20 Ultra.
What are the unique features of the Galaxy S20 LED back cover?
Samsung introduced the first generation of LED back cover with Galaxy S10. It was slightly changed for Galaxy Note 10 (and Note 10+).
So, Galaxy S20 LED back cover (aka Galaxy S20 LED cover in some regions) is actually the second generation of this cover with dramatic changes in materials.
Please do not confuse LED back cover with Galaxy S20 LED View (wallet) cover. The later is a flip cover with a pocket inside for a card. While Galaxy S20 LED back cover (or Galaxy S20 LED cover) is a one-piece back cover.
The unique features of the Galaxy S20 LED back cover includes:
- Light up when facedown. The back cover can light up when you put the phone face down.
- Customizable lighting style: mood lighting or LED icon. When Galaxy S20 is facing downwards, You can customize the lighting as mood lighting or a LED icon.
- LED notification icons for message apps and incoming calls. You will see the notification icons on the back when a notification from any message apps comes or when there is an incoming call. Please note, the notification LED icon is only available for messages apps including Messages, WhatsApp, Telegram, WeChat, Facebook Messenger and a few others. The notification LED icon cannot be customized (this is different from the Galaxy S20 LED View Wallet Cover).
- Camera timer countdown. If the timer for the rear camera is turned on, the countdown will be shown on both the screen and the cover.
- LED icons
This Galaxy S20 guide first covers the differences between status icons and notification icons on Galaxy S20, then explains the meaning of Galaxy S20 status icons and notification icons in Galaxy S20, S20+, and S20 Ultra.
Because Samsung uses slightly different icons in different regions or for some carriers, you may get the notification icons or status icons that are different from shown in this guide. It is normal. If you cannot figure out the meaning of those icons, you may share the screenshot on our FaceBook page so that others can help you identify them.
What is the difference between status icons and notification icons on Galaxy S20?
All Android phones including Galaxy S20 use the top part of the screen as the status bar to display some icons indicating the system status, alerting you possible issues and notifying you about incoming notifications.
Traditionally, a status icon refers to the icons telling you the phone status (e.g., mobile network status, WiFi status, battery percentage, or battery charging status), They are typically displayed on the right side of the status bar and aligned to the right side of the screen.
The status icons on the Galaxy S20 are always shown on the left side of the status bar, as shown below. These notification icons include notifications from all apps(system apps and normal apps).
Since Android 9, Google has moved the time to the left side of the status bar. The notch or hole-punch for the front camera usually are located in the status bar. So, the space for notification icons becomes very limited.
To avoid the overcrowded notification icons, Galaxy S20 allows you to customize how the notifications are shown (all notification icons, the 3 most recent icons, or just the number of notification icons) as explained in this guide.
The differences between status icons and notification icons on Galaxy S20 include:
- Status icons are always related to the system; while notification icons are usually linked to specific apps (including a few system apps and third-party apps).
- Status icons are shown on the right side of the status bar; while Galaxy notification icons always appear on the left side of the status bar.
- Status icons are more or less universal
Galaxy S20 Recents screen (aka overview screen, recent task list, or recents apps in the stock Android) lets you switch back to recently used apps quickly, or launch apps in the multiwindow mode (pop-up view or split-screen view) on Galaxy S20 easily.
This Galaxy S20 guide explains everything you need to know about the Galaxy S20 Recents screen, shows you how to access, navigate, and customize the Recents screen on Galaxy S20, and demonstrates how to use Galaxy S20 Recents screen to launch apps in the multi-window mode.
The Overview screen (Recents screen) on Galaxy S20, S20+, and S20 Ultra is identical. So, this guide applies to all these 3 models of Galaxy S20, although we use S20 in the text.
What is the Galaxy S20 Recents screen? Why is it important?
Like in other Android phones, Galaxy S20 Recents screen is a system-level UI component that lists recently accessed apps on Galaxy S20. It does not depend on individual apps or third-party launchers.
In other words, unless you root the phone, the Recents screen is always there. You cannot hide or disable it.
App developers cannot exclude their apps in the Recents screen. Instead, they can register some tasks of their apps as individual “apps” in the Recents screen. For example, if you open two documents in Google Docs, then you can find two entries in the Galaxy S20 Recents screen.
The Recents screen is designed for productivity. It is intended to help you switch among apps quickly.
Since Android Nougat (Android 7.0), Google finally introduced multi-window (split-screen view) into the stock Android. You have to launch apps in the split-screen view from the Overview screen in the stock Android.
Samsung added the multi-window feature since Android Ice Cream Sandwich (Android 4.0) with different ways to launch the app in the pop-up view or the split-screen view. But since Android Oreo, Samsung gradually streamlined the multi-window feature into the Recents screen.
So, the second common usage of Galaxy S20 Recents screen is to launch apps in the multi-window mode (split-screen view or the pop-up view).
Of course, you can also quickly manage the apps from the Galaxy S20 Recents screen.
How to access Galaxy S20 Recents screen?
Of course, you can use Galaxy S20 without a SIM card (you can use WiFi/Bluetooth/USB for connections). But it does not make sense to buy a Galaxy S20 if you plan to use it without a SIM card. You can get a WiFi-only tablet at a far cheaper price.
This Galaxy S20 guide explains the size of the SIM card on Gallaxy S20, possible configuration for the SIM card tray, how to use the SIM card on Galaxy S20 with or without a micro SD card, and how to use two SIM cards and eSIM on Galaxy S20.
The detailed explanation of eSIM support on Galaxy S20 can be found here.
What is the SIM card size on Galaxy S20?
Like most other phones released in recent years, Galaxy S20, S20+, and S20 Ultra all use nano-SIM cards only.
A nano-SIM card is the smallest one among the 4 possible SIM card sizes for mobile phones:
Most carriers now issue 3-in-1 SIM cards (as shown below). In this case, you can detach the largest part as a mini-SIM. Then you can get a micro-SIM card from the mini-SIM. A nano-SIM card can be detached from the micro SIM card.
You should keep the “waste” because they can be used as an adapter for micro-SIM (from nano-SIM card), or mini-SIM adapter (from micro-SIM). Some old tablets and MiFi (mobile router) may still require a larger SIM card.
If you are using a phone bought within the last 10 years, very likely, the phone is using a micro SIM card or a nano-SIM card.
It is possible (and simple) to trim a nano-SIM card from a micro-SIM card. But it is recommended to do it in the handphone shop using a properly-sized clipper. Do not use scissors.
Here is a list of some popular phones that use nano-SIM card already. If you want to migrate to Galaxy S20 from these phones, you can keep using the existing SIM card.
- Samsung Galaxy S6, S7, S8, S9, S10 and all their variants (e.g., S10, S10+, S10e, S9, S9+, S8, S8+, S7, S7 Edge, S6, S6 Edge, and S6 Edge+).
- Samsung Galaxy Note 5, Note 7 FE, Note 8, Note 9, Note 10, Note 10+,
This Galaxy S20 guide explains the differences between Galaxy S20 navigation buttons and Galaxy S20 navigation gestures, the two types of navigation gestures on Galaxy S20, and how to switch between navigation buttons and Galaxy S20 navigation gestures.
The navigation buttons or gestures are identical on Galaxy S20, S20+, and S20 Ultra. This guide applies to all of these three Galaxy S20 models.
What are the differences between Galaxy S20 navigation buttons and Galaxy S20 navigation gestures?
Traditionally, Android phones used hardware navigation buttons (3 buttons), then switched to software navigation buttons until Android Oreo (Android 8). In Android 9 (Android Pie), Google partially introduced navigation gestures (2-button navigation) and removed the Back button.
Samsung adopted different navigation gestures in Galaxy phones with Android Pie (Android 9) since Galaxy S10. It was ported to all Galaxy phones with Android 9 (e.g., Galaxy S9 and Note 9)
In Galaxy S20, Samsung still uses the navigation buttons as the default setting. You can switch to Galaxy S20 navigation gestures at any time.
As explained in this guide, Galaxy S20 navigation buttons include Home, Back, and Recents buttons. You need to tap one of the buttons to navigate among pages.
If you switch to Galaxy S20 navigation gestures, there will be no buttons. You will have to use gestures to return to the previous screen (Back), to jump to the Home screen, or access the Recents screen.
The differences between using Galaxy S20 navigation gestures and navigation buttons are substantial, for example:
- Navigation buttons and navigation gestures are mutually exclusive. You can only choose one.
- If you choose to use Galaxy S20 navigation gestures, then you have the option of using Samsung -style (Android 9)navigation gestures, or Google-style (Android 10) navigation gestures. (Read on)
- Some gestures may require some practice.
- Galaxy S20 navigation gestures can be more efficient only after you get familiar with them.

By default, when you set up the new Galaxy S20, you need to choose lock screen security type as one of the following:
- Swipe. There is no security. Anyone can swipe to unlock Galaxy S20. If you skip it during the initial setup, this method will be used. It is NOT recommended.
- None. This option actually turns off Galaxy S20 lock screen. So, it is NOT recommended.
Normally, the PIN is recommended. It offers moderate security for the phone. You can also choose to confirm PIN without tapping OK button. You can also hide PIN or password on Galaxy S20 when typing them.
If you set the lock screen type as pattern, PIN, or password, then you can use secondary biometrics to unlock Galaxy S20:
- Face. Face recognition is usually fast. But it requires good light conditions.

This Galaxy S20 guide explains the three navigation systems on Galaxy S20 (navigation buttons, Android 10 full-screen navigation gesture, and Samsung navigation gestures) and the functions and usage of Galaxy S20 navigation buttons (Recents, Back, and Home). It also shows you how to customize the layout (order) of Galaxy S20 navigation buttons
The navigation buttons are identical on Galaxy S20, S20+, and S20 Ultra, although we used Galaxy S20 in the guide.
What are the three navigation systems on Galaxy S20?
When you interact with Galaxy S20, you can use one of the following 3 navigation systems to navigate through different apps, or within an app, or through pages of Home screen, Apps screen, and lock screen:
- Galaxy S20 navigation buttons (the default).
- Android 10 full-screen navigation gestures.
- Samsung’s full-screen navigation gestures.
The full-screen navigation gestures remove all buttons (including the Home button). This guide explains these gestures and illustrates how to use them on Galaxy S20.
On the contrary, Galaxy S20 navigation buttons keep and use the traditional 3 navigation buttons.
Although navigation buttons look old-fashioned, they can be more efficient for many Galaxy S20 owners. This is the main reason why Samsung keeps Galaxy S20 navigation buttons as the default option when you set up Galaxy S20.
Please note, since Galaxy S8, Samsung ditched the hardware capacitive navigation buttons and adopted the software-based navigation buttons.
In other words, Galaxy S20 navigation buttons are NOT physical buttons (see Galaxy S20 layout). They are generated by the Android system when needed. And therefore, it is possible to disable/hide them and switch to full-screen navigation gestures without using any of these buttons.

Why is the Galaxy S20 lock screen so important?
Like in all other Android phones, Galaxy S20 lock screen is an essential part to secure your phone.
Basically, it is a door to your contents and private data. You are holding the key. And the key is your lock screen PIN/password/pattern.
So, Galaxy S20 lock screen protects your data from unauthorized access.

For Galaxy S20, if you forget the password or PIN, you can only unlock the phone with Samsung Find My Mobile as explained in this guide.

By default, when you unlock the lock screen, there is unlock sound. You can disable it in Settings — Sounds and vibrations — system sound/vibration control — screen lock/unlock, as explained in this guide.
