By simon Leave a Comment Last Modified: January 10, 2021 · Published on: December 19, 2020

Galaxy S20 recovery mode allows you to access some very special and advanced features to manage, hack and reset Galaxy S20.

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).
Power off Galaxy S20.

We will explain some of them later on.

How to use SanDisk Ultra Dual Drive USB Type-C on Galaxy S20, S10, S9 and S8?

You can simply plug SanDisk Ultra Dual Drive USB Type-C in and immediately use it on Galaxy S20, S10, S9 and S8 to transfer files, back up your data, or enjoy media saved in the drive.

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

How to customize Galaxy S20 ringtone quickly without using any third-party apps?

By simon Leave a Comment Last Modified: August 31, 2020 · Published on: September 3, 2020

You can use Galaxy S20 ringtone to identify calls from which SIM card, or from which contact without looking at the phone.

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

How to use different camera lens to zoom in and zoom out on Galaxy S20?

By simon Leave a Comment Last Modified: January 9, 2021 · Published on: July 27, 2020

Galaxy S20 is all about the camera. The three primary camera lenses on the back of Galaxy S20 allows you to zoom in and zoom out quickly to capture any objects/scenes far or close.

For example, Galaxy S20 Ultra offers up to 100x super-resolution zoom and up to 10x hybrid zoom.

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.

Wide-angle camera

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).

Ultra-wide-angle camera

The 12MP ultra-wide-angle camera is identical on all three Galaxy S20 models.

With a field of view (FoV) of 120˚, this camera allows you to capture … Read the rest

How to enable and use Galaxy S20 developer options?

By simon 7 Comments Last Modified: January 18, 2021 · Published on: June 21, 2020

You can enable and use Galaxy S20 developer options to access some advanced or experimental features.

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.

Update: After you update Galaxy S20 to Android 11, you may notice there are minor changes in the developer options. For example, you cannot find the option to customise the app icon shapes.

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

How to use a micro SD card on Galaxy S20?

By simon Leave a Comment Last Modified: December 19, 2020 · Published on: June 9, 2020

Samsung always supports the micro SD card support on all Galaxy S and Galaxy Note phones except on Galaxy S6 and Galaxy Note 5. Galaxy S20 can support a micro SD card up to 1TB.

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

Some Galaxy S20 owners may use the burst shot photos to make animations or even videos, which usually look better than the recorded video for the same event.

Please note, all photos taken in the Galaxy S20 burst mode are always saved in the phone storage even you set the photo storage location to the SD card in Galaxy S20 camera settings.

Galaxy S20 burst mode ios NOT listed with other Galaxy S20 camera modes because it requires a special gesture.

How to take burst shot photos with Galaxy S20 burst mode?

Meaning of status icons and notification icons on Galaxy S20

By simon 17 Comments Last Modified: January 18, 2021 · Published on: April 29, 2020

Understanding the meaning of status icons and notification icons on Galaxy S20 can help you get quick information about the phone status, system health, and notifications.

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

How to use and manage SIM card on Galaxy S20?

By simon Leave a Comment Last Modified: September 8, 2020 · Published on: April 25, 2020

You need a SIM card on Galaxy S20 if you want to connect the phone to a mobile network for voice, or data, or both.

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:

Standard.
Mini.
Micro.
Nano.

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+).

What is new in Galaxy S20 Clear View Cover (S View cover)?

Samsung changed the design of the Galaxy Note 10 Clear View cover dramatically (compared to S10 clear view cover) by introducing the long (and narrow) S View window.

Galaxy S20 clear view cover is clearly a refinement of Galaxy Note 10 clear view cover.

Here are the three new features or improvements of Galaxy S20 Clear View Cover.

#1. New S View window

The full screen S View window as in Galaxy S10 Clear View cover is a fingerprint magnet. Also, the cover only utilizes a small portion of the display (that is why it was named as S View window).

Galaxy Note 10 Clear View Cover is a good experiment for the new S View window. The long and narrow S View window is perfect for most owners. You can easily peek the S View window to see the notifications and time when it is on the desk.

Galaxy S20 Clear View Cover uses a similar S View window. But it is integrated into the front piece in a more natural way (read on),

In Galaxy S20, the new S View window is not on the edge of the front piece. Instead, it is embedded inside … Read the rest

Everything about eSIM support and use eSIM on Galaxy S20 and Galaxy S21

By simon 2 Comments Last Modified: March 31, 2021 · Published on: March 11, 2020

Galaxy S20, S20+, and S20 Ultra have eSIM support in most regions. But your carrier may not support eSIM on Galaxy S20.

This Galaxy S20 guide explains what eSIM is, the advantages of using eSIM on Galaxy S20, how to check eSIM support on Galaxy S20, how to add eSIM Profiles on Galaxy S20, and how to use eSIM on Galaxy S20 together with physical SIM cards.

Galaxy S21 also supports eSIM. This guide also applies to Galaxy S21, S21+, and S21 Ultra.

You may check this guide on how to use the SIM card tray and the physical SIM cards on Galaxy S20, and this guide on how to use SIM cards on Galaxy S21.

What is eSIM?

Traditionally, you need to get a SIM card from your phone company to make and receive phone calls, send and receive text messages, and use mobile data.

The SIM card is your ID. It is unique in the whole global mobile networks. The mobile operators use the SIM card to identify the company issued the card, whether this card can connect to their network or not, and what resources (mobile plan) you can use if you can connect to the network.

As the SIM card is unique, you have to get the physical card from the carrier. When you change carrier, you cannot use the old SIM card, and you have to get a new SIM card from the new carrier.

The process can be painful. Sometimes, you have to visit a physical store and queue there for one or two hours for the tiny SIM card. Or sometimes, you have to wait a few days before it is delivered to your mailbox.

It is even more painful or some frequent travellers who prefer using a local SIM card (to avoid exacerbate roaming charges). Every time, when you reach the destination airport, you have to walk around the airport to get a local SIM card. In some countries, the SIM card sold in airports is usually not good for value.

eSIM, embedded-SIM (or more officially, embedded universal integrated circuit card, eUICC), was proposed to tackle this issue (and other provisioning issues). The standard is maintained by GSMA.

In a nutshell, eSIM is embedded storage for SIM cards in your phone. You can save each SIM card info as a Profile.

And, you can save multiple Profiles on it. … Read the rest

Galaxy S20 LED View Cover (LED Wallet Cover)

By simon 3 Comments Last Modified: March 7, 2021 · Published on: March 7, 2020

Galaxy S20 LED view cover (aka Galaxy S20 LED wallet cover) is one of the official accessories for Galaxy S20, S20+, and S20 Ultra.

This Galaxy S20 accessories guide explains the unique features of the Galaxy S20 LED View cover, shows you how to use the cover (including assign and customise LED cions, accept and reject calls, control music), answers some questions you may have on this cover. A no-nonsense review of Galaxy S20 LED View cover is also included to help you decide whether this cover is for you.

The LED View cover works identically on Galaxy S20, S20+, and S20 Ultra, although there are some differences among these three Galaxy S20 models. So, in this guide, Galaxy S20 refers to all of these 3 models.

How does the Galaxy S20 LED View Cover (LED Wallet Cover) work?

LED View cover, which is a successor of LED Flip cover, was first introduced with the Galaxy S7 and S7 edge. Samsung changed the design and materials over the years.

But the fundamentals are still the same.

All Samsung LED covers, including the old LED Flip cover, LED View cover (LED Wallet cover in some regions), and the LED back cover, work through NFC technology.

There is no battery in the LED cover. The LED cover get power through NFC, NOT through wireless charging. But it does affect wireless charging (for safety reasons). When you charge Galaxy S20 battery with a wireless charging pad, the wireless charging will be paused automatically when LED icons are shown. And it resumes once the LED disappears.

The communication between the phone and the cover does NOT rely on the NFC settings. It is hardcoded in the firmware. Even you turn off NFC on your phone, the LED cover still works normally.

So, this is totally different from how S Pen on Galaxy Note devices works. S Pen does NOT use NFC.

The old S Pen (until Galaxy Note 8) does not have a battery. You do not need to charge it. These old S Pens get power from the screen (through electro-magnetic grid under the screen) when you use it.

The new S Pen in Note 9 has a supercapacitor and the S Pen in Note 10 has a real battery. Both of them will be charged when you put them in the S Pen slot. The “wireless charging” is … Read the rest
