Galaxy S10 Guides

a owners-help-owners community of Samsung Galaxy S10, S10+ and S10e

In April 2023, Samsung finally pulled the plug to stop issuing the security update for Galaxy S10, S10+, and S10e.

With 3 major Android (and One UI ) updates for Galaxy S10, S10+, and S10e, Samsung did keep its word on both major OS updates and security updates.

From now on, you will not expect any official new updates (unless it is very, very critical) from Samsung for your Galaxy S10, S10+, and S10e.  Very likely, Samsung will also end the security update for Galaxy S10 5G this summer.

This Galaxy S10 guide explains Samsung’s promise on the software update for Galaxy S10, S10+, and S10e, the update history for these 3 phones and the key features in each update, and what you should do next.

Samsung keep its word on both OS and security update for Galaxy S10, S10+ and S10e

When Galaxy S10 was released in 2019, Samsung promised 3 major software updates and 4-year security update. Obviously, Samsung kept its word.

Galaxy S10 was released with Android 9 (One UI 1.1) and was updated to Android 10 (One UI 2), Android 11 (One UI 3), and Android 12 (One UI 4) subsequently.

As promised, Galaxy S10, S10+, and S10e stopped at Android 12 and was not received the Android 13 update (One UI 5) last December.

Now, after 4 years of its initial release, Galaxy S10 marches to the end of life: no more official security updates for Galaxy S10, S10+, and S10e.

Please note the commitment of 4 major OS updates and 5-year security updates applies to Galaxy S21 and later Galaxy devices.

Overall, Compared to other Android vendors, Samsung did an excellent job providing Android and security updates for Galaxy S10 and later devices.

The three major updates for Galaxy S10, S10+, and S10e

As mentioned, Galaxy S10 was released with Android 9 (Android Pie) and One UI 1.1.  Here is the list of the top 10 new software features of the original Android 9 (One UI 1.1) and three major updates for Galaxy S10, S10+, and S10e: Android 10 (One UI 2), Android 11 (One UI 3), and Android 12 (One UI 4).

The post End of security update for Galaxy S10, S10+ and S10e appeared first on Galaxy S10 Guides.

Samsung started to roll out the Android 10 update for Galaxy S10 in December 2019. The update is expected to reach almost all Galaxy S10 (S10, S10+, S10e, and S10 5G) by Q1 2020.

In most regions, the Andriod 10 update should be available by January 2020.

Android 10 update for Galaxy S10 is the first major update for the device. Some Galaxy Note 10 new features were ported to Galaxy S10 in the September 2019 update as explained in this post. But in some regions, this feature update is combined with the Android 10 update.

Of course, Galaxy S10 (all 4 variants) will get the new version of Android (Android 10). In addition to the underhood improvements in performance, security, and privacy, most of the Android 10 features are available in Galaxy S10 now.

This Galaxy S10 guide explains the top 10 new features you should try in the Android 10 update for Galaxy S10: native screen recorder, Android 10 navigation gesture, more info in Device Care, tweaked camera UI, enhanced biometrics, power limit for Wireless PowerShare, improved one-handed mode, OneDrive integration in the Gallery app, dark mode, and One UI 2.0.

Update: after receiving two additional major updates: Android 11 (One UI 3) update and Android 12 (One UI 4) update, Galaxy S10, S10+, and S10e reach to the end of life. Samsung stopped releasing security updates for Galaxy S10, S10+, and S10e from April 2023.

Native screen recorder

In addition to streaming your screen (e.g., play games), screen recording (not just screenshots) is very useful for technical support and sharing procedural info.

Samsung first introduced the native screen recorder in Galaxy Note 10. Now in the Android 10 update for Galaxy S10, all S10 phones (including S10e, S10, S10+, and S10 5G) have this nice feature.

Compared to the screen recorder on Galaxy Note 10, Samsung apparently polished the app a bit in Galaxy S10 so that you get more control.

Android 10 navigation gesture (full-screen gestures)

Google introduced navigation gestures in Android Pie with a Home button and an Overview button. In Android 10, the navigation gestures can be used without any buttons (aka, full-screen gestures).

In the Android 10 update for Galaxy S10, the new Android 10 navigation gestures were added.

Of course, you can still use Samsung’s navigation features introduced in Android Pie (Android 9).

If you are not a fan of either of the navigation gesture implantations, you can use the traditional navigation buttons.

Anyway, the Android 10 navigation gesture is just an additional option.

You may check this guide on how to use navigation gestures on Galaxy S10 after the Android 10 update.

More info from Device Care

Device Care now offers more information on most cards.

For example, in the battery usage card, you can get more detailed information about battery usage and estimation.

You may check this guide on how to use Samsung DeX for PC on Galaxy S10.

Link to Windows

Link to Windows is a special version of Your Phone Companion app, which allows you to access and manage app notifications, check and reply messages,  share recent photos (up to 25)  on the PC/laptop.

Previously, you can download and install the app from Play Store.

But Link to Windows offers more than the Your Phone Companion app does, for example:

• Link to Windows offers screen mirroring (through WiFi). You can mirror the phone screen to the PC or laptop. Then use all apps installed on the phone with keyboard and mouse on the PC or laptop.
• You can access Link to Windows with the quick setting buttons.

Please note, Link to Windows on Samsung Galaxy S10 requires Windows 10.

New camera features

Samsung also ported some Galaxy Note 10 camera features into Galaxy S10 in this update.

Live focus video allows you to blur out the background when recording a video.

It works just like the live focus mode for photos.

You can find the Live Focus Video mode among the camera modes in the Galaxy S10 camera app.

AR Doodle

AR Doodle lets you record fun videos with handwriting or drawings on faces or other places. The doodles on the face can move with the face. The doodles in the space will be fixed in the same place, even … Read the rest

Galaxy S10 wireless charging allows you to charge Galaxy S10 battery without using a cable on the phone.

But some Galaxy S10 owners still have some questions or concerns about using wireless charging on Galaxy S10 and therefore may haven’t tried this nice feature yet.

This Galaxy S10 how-to guide first explains the confusing terms of wireless charging, fast wireless charging, and fast wireless charging 2.0, and why they are relevant when you charge Galaxy S10 wirelessly.   Then I will show you how to disable fast wireless charging and answer some questions related to wireless charging on Galaxy S10.

What is wireless charging? What is fast wireless charging? and what is fast charging 2.0?

All smartphones support cable charging.  Normally, you can connect the phone to the charger (adapter) through a USB cable (or a proprietary cable) to charge the phone.

The other way to charge a phone battery is wireless charging without using any cables on the phone.

Wireless charging used in the smartphone industry now is all inductive charging, which transfers energy from the charging station to the phone through induction coils.

On the charging station (charging stand, charging base), the induction coil inside the station uses the current from the adapter to create an electromagnetic field. The induction coil in the phone, once paired with the coil in the station,  takes power from the electromagnetic field and converts it into charging current for the phone battery.

Wireless charging usually is less efficient than cable charging because energy has to be converted twice: current –> electromagnetic field in the charging station, and electromagnetic field –> current on the phone.  So, traditionally, the wireless charging speed is slow. The normal wireless charging can only output charging power up to 5W.  Galaxy S6 is the first Samsung phone with wireless charging.

To improve the charging speed, Samsung announced fast wireless charging with Galaxy S7.  The maximum charging power output is about 7.5W.

With Galaxy S10, Samsung announced fast wireless charging 2.0, which supports up to a 12W output.

As explained in this guide:

Fast wireless charging 2.0 is based on Qi wireless charging standard set by Wireless Power Consortium. The 2.0 was coined by Samsung to differentiate its implementation from previous fast wireless charging.

So, fast wireless charging 2.0, one of the top 10 new features of Galaxy S10, is not a new industry standard.

The major difference among wireless charging, fast wireless charging, and fast wireless charging 2.0 is the charging power (5W vs 7.5W vs 12W). And therefore, they are backwards compatible.

What do you need to use wireless charging for Galaxy S10 battery?

You need 3 components to use wireless charging:

1. A phone supports wireless charging.
2. A wireless charging station.
3. An adapter that supplies power to the charging station.

Whether you are using normal wireless charging, fast wireless charging, or fast wireless charging 2.0, is determined by the lowerest one among the 3 components.

For example, since Galaxy S10 … Read the rest

You can use app folders on Galaxy S10 Home screen and Apps screen to organize apps and reduce the number of panels (pages).

Although it is not a new feature, many Galaxy S10 owners may be confused about the differences when managing app folders on the Home screen and Apps screen.

This Galaxy S10 how-to guide explains why you need app folders, the limitation of the app folders, how to create, use, and manage app folders on both Galaxy S10 Home screen and Apps screen.

If your Galaxy S10 has been updated to Android 12, you may check this updated guide on how to use app folders on Galaxy phones with Android 12 (One UI 4).

What are app folders on Galaxy S10? Why do you need them?

App folders are simply a folder of app icons.  On Galaxy S10 Home screen and Apps screen, each app folder occupies one slot  (grid point), like one app icon.

So, using app folders can help you:

• Save screen space. You do not want to scroll 20 home screen panels to find an app.
• Organize apps. You can organize similar apps or apps from one developer into one app folder so that you can locate them very quickly.

In fact, when you unboxed your Galaxy S10, you already found the Samsung folder and the Google folder in Galaxy S10 Apps screen.

Please note, although Galaxy S10 lock screen has two spots (bottom left and right) for two apps, you cannot use app folders there.

Galaxy S10 Edge screen supports app pair, and app folders (which are created in the Edge screen) on the Apps edge.

What are the limitations of app folders?

There are a few limitations when you use app folders on Galaxy S10, including

• Galaxy S10 does not support nested app folders.  You are not allowed to put an app folder under another app folder.
• You cannot customize the screen grid for the app folders.  In Galaxy S10 Home screen settings, you can customize the screen grid from 4×5 to 4×6 to 5×5 or to 5×6. But the layout of app icons inside the app folder is always 4×4. If you put more than 16 apps in one app folder, a new panel inside the folder will be added automatically.
• On Galaxy S10 App screen, one app icon can appear only in one app folder.  All app icons on the Apps screen can only be shown once. When you put an app into an app folder in the Apps screen, this app icon will only appear in the app folder. You cannot find it elsewhere on the Apps screen. Please note, Galaxy S10 Home screen does not have this limitation. In other words, one app icon can appear multiple times, including multiple app folders on the Home screen.
• You can only use app folders on Galaxy S10 Home screen and Apps screen. You cannot use them on the

Galaxy s10 developer options offer some hidden features for phone enthusiast, not just developers.

By default, the developer options are hidden on all Android phones. You can unhide them on Galaxy S10, S10+, S10e, and S10 5G, then use them.

This Galaxy S10 how-to guide explains what you can do with the Galaxy S10 developer options, shows you how to enable and unhide the developer options, how to disable them after enabling them, and lists the available developer options on Galaxy S10.

What are Galaxy S10 developer options?

Traditionally, Android developers can access some special features to:

• Test their apps.
• Enable USB debugging.
• Use ADB commands.
• Monitor resource usage.
• Limit resource usage.
• Enable some beta features.

Of course, in addition to developers, more and more experienced Android users also enable some features in the developer options.

In recent years, before a new version of Android is officially released, Google released beta or developer versions to developers to help them migrate apps to the new Android versions.

In these developer releases or beta releases, a lot of new features are hidden in the developer options. Google later moves some of them to the official features. Of course, some also stay in the developer options.

When the new version of Android is released, Google usually removes most of the beta features that were not delegated to official features from the developer options and only keeps common tools and features and a few beta features.

Samsung may also add or remove some entries in the developer options on Galaxy phones.

For Galaxy S10 owners, you may also find that the developer options are useful. For example,

• You can enable quick settings developer tiles (e.g., the night mode button in the quick settings panel).
• You can enable USB debugging so that you can access some features from a PC (e.g., taking a lot of screenshots from a PC).
• You can enable Wi-Fi safe mode.
• You can change the default Bluetooth audio codec.
• You can set animation speed or disable animation to make Galaxy 10 “look” faster.
• You can manage and limit the background processes.
• You can allow all apps to use external storage (e.g., SD card).
• You can also force all apps to be compatible with Galaxy S10 multi-window.

In short, the developer options on Galaxy S10 are not only for app developers. They may improve your experience with Galaxy S10 if you know what you want.

How to unhide (enable) developer options on Galaxy S10?

In all Android phones, the developer options are hidden by default. Galaxy S10 is not an exception.

To unhide or enable Galaxy S10 developer options, you may follow these steps:

Step 1: Open Galaxy S10 Settings

What is Samsung Finder? And what are the suggested apps on Galaxy S10?

When talking about search, many think about Google.

But on Galaxy phones, Samsung has built its own local search engine for a long time. And they named it Finder in recent devices or S Finder in older devices.

Galaxy S10 night mode allows you to use the dark theme in system-wide to help your eyes and save battery. So, it is sometimes called the dark mode.

On Galaxy S10, Samsung chose to extend the dark theme features in the stock Android Pie to deliver better user experiences with the new One UI.

This Galaxy S10 how-to guide explains the details of the night mode on Galaxy S10 (including Galaxy S10, S10e, S10+, and S10 5G), and shows you how to enable and customize the night mode.

What is Galaxy S10 night mode? Why you may need it?

By default,  Android phones tend to use a white background. This usually looks great when you show the screenshot in presentations.

But it is not good for your eyes, especially in the low-light conditions, for example, in a theatre, or in the bedroom.

For the OLED screen like the one in all Galaxy S10 phones, the black (dark) background can save noticeable battery as well.

In Android Pie (Android 9), Google finally introduced the dark theme. But it is half-baked: the setting page still uses a white background even you enable the dark theme, as explained in this guide.

Samsung started to support third-party themes since the Galaxy S6. So, technically, you can get a dark theme for your S6, S7, S8, S9, and S10 with a third-party theme from the Galaxy Store. But the quality of these third-party themes varies sharply.

In Android Pie update, Samsung implemented and enhanced the dark theme feature in the stock Android. And it is named as the night mode.

So, Galaxy S10 night mode is essentially an enhanced (improved) version of the dark theme in Android Pie.

You should not confuse this night mode with the newly added night mode in Galaxy S10 camera app, which is just a camera mode for low-light conditions. The night mode discussed here is a theme (or template) with a dark (black) background.

In the Android 10 update for Galaxy S10, a new dark mode was introduced. In Android 12 update for Galaxy S10, you may use Extra Dim to dim the screen beyond the minimum brightness level.

How to enable and customize the Galaxy S10 night mode?

By default, the night mode is not enabled on Galaxy S10 (S10, S10+, S10e, and S10 5G). You need to enable it by following the steps below if you want to try or use the night mode.

In Galaxy S10 Settings, tap Display as shown in the screenshot below.

In the Display settings page, as shown above, you can find the Night mode option.

You can tap the switch (or drag it to the right side) to enable the night mode immediately.

Of course, you can tap Nigth mode (not the switch) to open the night mode settings so that you can further customize (schedule) it.

As shown below, you can use the night mode on Galaxy S10 in two ways… Read the rest

When Galaxy S10 hangs, you can hold the Power button AND the volume down button for more than 7 seconds to reboot the phone forcefully.

There are a few other combinations of keys (buttons) that you may need to know to power off, power on, reboot, reboot into recovery mode, or reboot into download mode on Galaxy S10, S10+, S10e, and S10 5G.

This Galaxy S10 how-to guide explains how to reboot Galaxy S10 when the phone hangs, and other key combinations for powering on, powering off and rebooting Galaxy S10 (including all 4 Galaxy S10 models).

How to reboot Galaxy S10 when the phone hangs?

Although it happens rarely, Galaxy S10 may hang (not responsive), just like other electronic devices or other Android phones.

If this happens to your Galaxy S10, you may also find the phone does not respond to the power button as well.

Up to Galaxy S5, Samsung used a removable battery in their phones and you can remove the battery to force a reboot.

But since Galaxy S6, Samsung has switched to non-removable batteries. And therefore, the battery removing method is not working for Galaxy S10.

So, when Galaxy S10 hangs (even not responsive to the power button), you can hold the Power button and the volume down button (2 buttons), as shown below, for more than 7 seconds to reboot the phone forcefully. You may check the Galaxy S10 layout to locate the buttons.

Technically, holding these two buttons is equivalent to removing (and putting back) the battery.

Using the power button and power button menu on Galaxy S10

Normally, you can press the power button on Galaxy S10 to:

• Power on the phone (when the phone is off).
• Wake up the screen (when the screen is off).
• Turn off the screen and lock the phone. (when the screen is on)
• Take photos in the camera app (if you enable it).
• End a call (if you enable it).

If you quickly press the power button twice, you can launch the camera app. This is called Galaxy S10 camera quick launch.

You can also call out the power button options (power button menu)  as shown below by long-press the power button for about 2 seconds.

In Galaxy S10 power button menu, there is no shortcut for the screenshot. This is different from the stock Android Pie. If you need to take screenshots, you may check this guide.

Please note, normally, you need to use the Power off button in the power button menu to power off Galaxy S10.

The Reboot button allows you to reboot Galaxy S10 gracefully. Reboot Galaxy S10 gracefully will not lose any data. But if you reboot Galaxy S10 forcefully, all unsaved data will be lost.

If you hold the power button for more than 5 seconds, Galaxy S10 will reboot.

By default, Galaxy S10 camera app saves front camera photos as in the preview screen,  which is mirrored. Very often, you may want to avoid mirrored photos.

Although you can rotate the photo in any photo editors, you can easily change camera settings to avoid mirrored photos.

This Galaxy S10 camera guide explains why you get the mirrored photos, how to stop saving mirrored photos, and how to flip the mirrored photos as normal photos without using any third-party apps.

Why do you get the mirrored photos from Galaxy S10 front camera?

When you take selfies with Galaxy S10 front camera (see Galaxy S10 layout), the preview screen shows you a “mirrored” image for you to check.

Actually, all smartphone front cameras work in this way. This is consistent with what you do with makeups and clothes: you check them with a mirror.

But very often the mirrored photo is not what you want for a selfie photo. You often want to get a “normal”, not mirrored (flipped), photo, as what you get from the rear camera.

Unfortunately, most Android phone manufacturers by default save the mirrored photo for the front camera.

Of course, when saving, most Android phone manufacturers allow you to change the saving option in camera settings to avoid the mirrored photos.

Google Nexus and Pixel phones always avoid the mirrored photo when using the front camera. Actually, on Nexus and Pixel phones, there are no options for you to save a “mirrored” photo, although in the preview screen you get the mirrored image.

So, do not blame the Galaxy S10 front camera if you hate the mirrored selfies.

You should blame Samsung’s developers, who set the default as saving the mirrored photos.

Of course, you can change the Galaxy S10 camera settings to stop saving mirrored photos (read on).

For the mirrored photos saved on your phone, you can also easily flip them back to normal photos (read on).

How to avoid the mirrored (flipped) photos from Galaxy S10 front camera?

As mentioned, the mirrored photo issue is due to the default settings. You may follow these steps to stop saving the mirrored photos.

Step 1. Open the Camera app

You can open the camera app from the Galaxy S10 Home screen, or apps screen, or even the lock screen.

Step 2: Access camera settings

As shown in the screenshot below, tap the Settings icon (marked as 1) to access Galaxy S10 camera settings.

You can find a lot of options related to photo settings. For example, you can also change photo size settings for Galaxy S10 cameras.

Step 3. Change save options

In the camera settings, tap Save options as shown above.

Step 4. Disable save pictures as previewed

To avoid the mirrored photos, you can disable the Pictures as previewed in the save options.

As shown below, tap Picture as previewed to disable the mirrored photos.

Please note, in old Galaxy phones, the option may be named as “save … Read the rest

Galaxy S10 clear view cover (aka Galaxy S10 S-View flip cover) is one of the flagship accessories from Samsung for S10, S10e,  S10+, and S10 5G.

The unique S-View features make the cover stand out, although some original S View features were removed or redesigned.

This Galaxy S10 accessories guide explains the changes, special features, pros and cons of the Galaxy S10 clear view cover. It also shows you how to customize and use the cover, and how to use the always-on display on the clear view cover.

The S View cover is available for all Galaxy S10 models (S10, S10+, S10e, and S10 5G). The only difference is the cutout and size of the case. In this guide, S10 refers to all of the four S1o models.

What’s new in the Galaxy S10 clear view cover (S-View flip cover)?

Samsung always releases some “official” accessories for its Galaxy phones.

Galaxy S10 clear view cover, aka Galaxy S10 S-View flip cover in some regions, is an evolution of the “S View” cover.

But compared to the Galaxy S9 clear view cover and Galaxy S8 clear view cover, there are some changes:

• No kickstand. The kickstand in S-View serials covers for S8, S9, Note 8 and Note 9 was removed in S10.
• Glossy back. The glossy plastic replaces the texture-rich back. It is a fingerprint magnet.
• Some textures “inside” the front panel. The translucent front panel looks similar to that in S9. But if you stare at it at 90 degrees, you may notice there are some textures. Of course, the texture is inside, not outside of the panel.
• Lighter and thinner. Because the kickstand was removed, the cover is lighter and thinner compared to that for S9.

On the software side, there are almost no changes.

What are the special features of the clear view cover (S-View flip cover)?

Galaxy S10 clear view cover shares similar S-View features as in S9 and S8:

• Respond to calls, alarms, and events without flipping the cover.
• Control music on the cover.
• Read important information, including time, date, and battery level on the cover.
• Auto lock and unlock.
• Use faceWidgets on the cover.

Please note, there is no separate S-View window as in Galaxy S7 S-View cover.  Since S8, the full front panel is translucent.  The actual display is always on the phone screen.

How to apply and remove the Galaxy S10 S View cover?

When you apply the Galaxy S10 clear view cover to Galaxy S10, S10e, S10+, and S10 5G, you should fix the top part first. Then finish the bottom part.

When you want to remove the cover (to take out the phone), you should start from the bottom. Once the bottom part of Galaxy S10 is taken out of the cover, you can easily take the phone out.

Do NOT try to start from the top if you want to remove the cover. You may damage the cover … Read the rest

Galaxy S10 Apps screen organizes all apps installed on the phone so that you can access, use and manage them easily.

This Galaxy S10 how-to guide explains what Galaxy S10 apps screen is, how to access it, how to hide apps button, how to hide the apps screen, and how to customize the apps screen on Galaxy S10.

This guide applies to all Galaxy S10 modes: Galaxy S10, S10e, S10+, and S10 5G.

What is Galaxy S10 Apps screen?

Apps screen is common in all Android phones.  Sometimes (and traditionally), it is called App drawer.

Essentially, the Galaxy S10 Apps screen is the warehouse of all apps installed on the phone. The individual app icon on the home screen actually is a shortcut to the corresponding app in the Apps screen.

But Apps screen is different from the Home screen in the following aspects:

• Apps screen can only host apps. You cannot put widgets, apps shortcuts, user files, or photos in the apps screen.
• Apps screen does not support duplicate listings. One app can only appear once in the Apps screen.
• You can hide the apps screen. Surely, you cannot hide the home screen.

The Apps screen shares the same wallpaper with the home screen.

You can also use apps screen in the landscape mode (same as Galaxy S10 Home screen landscape mode).

How to access Galaxy S10 Apps screen?

By default, there are two ways to access Galaxy S10 App drawer:

1. Use the touchscreen gesture (swipe up). On the home screen, you can swipe upwards to access the apps screen as shown in the picture below.
2. Use the apps button in the favorites tray. You can tap the apps button to open the Apps screen.

By default, you can also use the swipe down gesture to access the apps screen on Galaxy S10.  But the swipe down gesture on Galaxy S10 home screen can be assigned to access notifications as explained in this guide (coming soon).

If you do not hide the apps button, you can tap the button as shown below to access the apps screen on Galaxy S10.

Of course, you can hide the apps button and access apps screen only with the touchscreen gesture.

Once in the apps screen, you can then swipe left and right to navigate to different pages.

You can swipe upwards or downwards in the apps screen to return to the home screen. The quick-open notification panel setting does not affect the apps screen.

How to hide apps button in the favorite tray?

In Galaxy S10 Settings, tap Display.

As shown in the screenshot below, in the display settings, tap Home screen.

On Galaxy S10, the apps screen settings are grouped under home screen settings.

As shown above, you can:

1. Show or hide the apps button (marked as 1) using the switch.
2. Set the screen grid for the Apps screen (read on).
3. Show or hide apps screen (read on )

Samsung added the Galaxy S10 camera night mode for the main camera in the April (2019) firmware update.  You can now use the dedicated camera night mode to take better photos in low-light conditions.

Update 1: Galaxy S10 camera night mode is now available for all camera lenses, including the selfie (front-facing) camera(s) following the Galaxy S10 September update.

This Galaxy S10 camera guide explains the details of the Galaxy S10 camera night mode, how to use the night mode, and differences between the night mode and the Auto (Photo) mode.

The camera night mode is available for all Galaxy S10 phones (S10, S10+, S10e, and S10 5G). In this guide,  Galaxy S10 refers to all these models.

Please do NOT confuse this camera mode with the dark theme (which is also called night mode).

What is Galaxy S10 camera night mode?

On Galaxy S10 (S10, S10e, S10+, and S10 5G), you may find there was no night mode for the camera when you got the phone.

Samsung removed the night mode from the camera app since Galaxy S6 as explained in this guide.

Although Samsung claimed the Auto mode (Photo mode) is good enough and you do NOT need a dedicated camera night mode, many owners do not agree. They want to get back the dedicated night mode.

On Galaxy S10, Samsung bragged about the Bright Night feature for the S10 rear camera and did not give users a dedicated mode for it.  It is supposed to help Galaxy S10 owners take nice photos in low-light conditions automatically. Apparently, the Photo mode often fails to deliver the promise.

So, in the Galaxy S10 firmware update released in April, Samsung finally added a dedicated night mode for the camera. For US versions of Galaxy S10 (all variants), the new camera mode was added with the June security update.

Yes, after 5 years (since Galaxy S5), Samsung finally realized the Auto mode (or the Photo mode) is not sufficient for taking photos in low-light conditions.

Now, on S10 (all variants), you can choose the night camera mode when you need to take photos when the light is not good.

Please note, the new Galaxy  S10 camera night mode is available only for the main rear camera (12MP).

Update: if your Galaxy S10 was updated to September (2019) security patch, then the nigh camera mode is available for all camera lenses as explained in this guide. You can even use the camera night mode when taking selfies with the front camera.

How to access and use the camera night mode?

You can access the camera night mode like other camera modes.

On the Galaxy S10 camera app interface, as shown in the screenshot below,  the default camera mode is Photo (aka Auto) mode (or the last used camera mode if you enable the option in Galaxy S10 camera settings).

You can swipe left as illustrated to access the new camera night mode.

Samsung Galaxy S10 edge screen allows you to access some features and apps quickly from the curved the display without navigating to the home screen or apps screen.

Since the inception of the curved-screen in Galaxy Note Edge, Samsung tried hard to develop some killing features for the curved screen.

This Galaxy S10 how-to guide explains everything you need to know about Galaxy S10 edge screen.: what is edge screen, how to access and use edge screen, edge lighting, edge panels, and Apps edge.

What is Galaxy S10 edge screen?

Samsung introduced the edge screen feature since Galaxy Note Edge (Note 4 Edge). But edge screen on Galaxy Note Edge is a separate display area to the right side of the main screen.

Since Galaxy S6 Edge, edge screen has been no longer a separate part. It refers to a part of the main screen linked to the curved edges of the display.

So, Galaxy S10 edge screen is not a separate screen. Instead, it is just part of the display close to the curved edges on both sides of Galaxy S10, S10+ and S10 5G as illustrated in Galaxy S10 layout.

Because Samsung started to reduce the curved part of the screen from Galaxy S8, many new Galaxy S8, S9, Note 8, Note 9 and S10 owners may even not realized the curved edges and the special features associated with them.

Galaxy S10 edge screen includes two fundamental features:

1. Edge lighting. You can use edge lighting the light up the edges of the screen when notifications arrive.
2. Edge panels. You can put frequently used apps and some special tools in the panels so that you can access them quickly.

If you disable both edge lighting and edge panels, Galaxy S10 edge screen will be disabled automatically. This is the only way to disable Galaxy S10 edge screen features.

Galaxy S10 edge screen works on all screens (except AOD)and apps when in portrait mode. You can use it on the home screen, lock screen, apps screen, and when using any apps.

When you use edge screen on the lock screen, some features will not work until the phone is unlocked. This is a security feature, not a bug.

If your home screen or lock screen is in landscape mode, or you are using an app in landscape mode, edge panel handle will disappear automatically. In other words, Galaxy S10 edge screen does NOT work in landscape mode.

How to access the edge screen?

You can access the Galaxy S10 edge screen by dragging the edge panel handle to the center of the screen, as shown below.

The edge panel handle appears on the right side by default. You can customize it so that it can appear on either left or right sides. You can also choose a color for it (read on).

The touchscreen gesture is dragging. But the swipe gesture works as well.

Galaxy S10 Home screen edit mode allows you to customize the home screen with themes, widgets, screen panels, wallpapers.

Although some customizations and options can be accessed from Galaxy S10 settings or quick settings, a few features can only be accessed from the Galaxy S10 home screen edit mode.

This Galaxy S10 how-to guide explains when you need to use Galaxy S10 home screen edit mode, what you can do in the edit mode, and how to access and use Galaxy S10 home screen edit mode.

What is Galaxy S10 home screen edit mode?

It is impossible to stuff all customizations and settings into Galaxy S10 Settings. Also, some customizations for Galaxy S10 can be done quickly on the screen with simple gestures.

So, Samsung used the home screen edit mode for you to quickly customize the home screen without navigation through the Settings or other pages.

In a nutshell, the home screen edit mode is a special mode of the home screen. In this mode, you can customize many aspects of the Galaxy S10 Home screen.

And some settings/customizations for Galaxy S10 Home screen can only be done through this mode. For example, assigning a home screen panel as the “Home” of Home screen panels/pages, or remove the Bixby Home from Galaxy S10 Home screen, or adding widgets to the home screen, all can only be done in the Galaxy S10 Home screen edit mode.

Of course, some features in the edit mode can also be accessed from Galaxy S10 Settings (for example, adjust Galaxy S10 home screen settings), or standalone apps/app shortcuts (e.g., use themes and wallpapers).

How to access the Galaxy S10 home screen edit mode?

You can only use touchscreen gestures to access the home screen edit mode.

There are two gestures for you to access the edit mode for the Home screen:

1. Tap and hold (long tap) any blank area on the Galaxy S10 Home screen.
2. Pinch on the Galaxy S10 home screen.

These are the two only methods to enter the S10 home screen edit mode.

When you use the first gesture (long tap), you need to make sure you are tapping the empty (blank) area except for the status bar and navigation bar.

You can tap anywhere above home screen panel indicator (see below) or tap the back button to exit the edit mode and return to the Home screen.

What are the features of Galaxy S10 home screen edit mode?

As shown in the screenshot below, you can find the following common features and functions in the edit mode of  S10 Home screen:

1. Assign the panel/page as the home of the Galaxy S10 Home screen. If you keep tapping the Home button, you should return to the “Home” of the home screen. You must have one and only one panel/page as the home of the home screen panels.
2. Delete the page.  If this is the “home” panel and you delete it, the

You can use Galaxy S10 always-on display (AOD) to check notifications, the time, next alarm, today’s schedule, and the weather,  and to control music play without waking up the phone.

On Galaxy S10, Samsung added a few new features for the always-on display and the default behavior. So, do NOT assume the AOD on Galaxy S10 is identical to that on older phones like S9.

This Galaxy S10 how-to guide explains the new features of the Galaxy S10 always-on display (AOD), the difference between Galaxy S10 lock screen and AOD screen, how to enable and customize the always-on display screen on Galaxy S10.

Please note, the always-on display is identical among all Galaxy S10 phones.  In this guide,  Galaxy S10 refers to Galaxy S10e, S10, S10+, and S10 5G,

What is new in Galaxy S10 Always On Display (AOD)?

In all previous Galaxy phones, the always-on display screen will not be turned off automatically unless it is turned on by the scheduler.

So, once you turn on the always-on display on these devices, you have to choose to show the AOD screen all the time when the phone is locked or to show the AOD screen based on your designated period.

On Galaxy S10, Samsung added the show mode for the always-on display screen: tap to show. And this is the default option.

So, after enabling Galaxy S10 always-on display, by default, the AOD screen will NOT show up after you lock the phone unless you tap the screen (once).

The AOD screen will display only about 10 seconds, and then the screen is off.

If you need to show Galaxy S10 AOD screen all the time, you need to change the show mode.

This new show mode is also available on Android Pie update for Galaxy S9, S8, Note 9 and Note 8.

Please note, if you tap Galaxy S10 screen twice when the screen is off, you will wake the screen and get the Galaxy S10 lock screen, instead of the always-on display screen.

Of course, you can disable this feature in Settings —Advanced features —Motions and gestures — Double tap to wake.

Other new features of Galaxy S10 Always on Display include:

• Landscape mode for Galaxy S10 AOD screen.
• Brightness adjustment for the AOD screen.
• Quick settings for AOD.

AOD Quick settings can also be found on Galaxy S9, S8, Note 8 and Note 9 if you updated these phones to Android Pie.

What is the difference between the lock screen and the always-on display screen?

Although Galaxy S10 always-on display screen is part of the Galaxy S10 lock screen and shares the identical FaceWidgets, they serve different purposes.

The major differences between the AOD screen and lock screen include:

• Galaxy S10 lock screen shows up when the phone wakes up and is in the locked state. While Galaxy S10 AOD screen shows up only when the phone is NOT waking up.
• You can use app shortcuts in

You can use Galaxy S10 wireless PowerShare to charge other devices wirelessly using Galaxy S10’s battery.

Galaxy S10 (including Galaxy S10, S10+, S10e, and S10 5G) can be used as a wireless charger to share Galaxy S10 battery with other devices.

This Galaxy S10 new feature guide explains the details of Galaxy S10 wireless PowerShare feature, how to use it to charge other devices, and answers some questions you may have when using the wireless PowerShare.

Update: with Android 10 update, you can now set the battery limit for Wireless PowerShare. Please refer to this guide on how to set the battery limit for Wireless PowerShare.

Please also note, Galaxy S20, Galaxy S21, Galaxy Note 10, and Galaxy Note 20 all support Wireless PowerShare. So this guide also applies to all these phones.

What is Galaxy S10 wireless PowerShare?

Wireless charging is not new. Samsung added it as a standard feature since Galaxy S6.

But using the phone as a wireless charger to share the phone battery with other devices is still new.

Huawei named this feature as wireless reverse charging and introduced it in Mate 20 Pro (in 2018) and P30 Pro. Samsung introduced this feature in Galaxy S10 (all 4 models) and named it as wireless PowerShare.

Galaxy S10 wireless PowerShare lets you share the battery juice of Galaxy S1o with other devices that support Qi wireless charging.

Technically, you can still use Galaxy S10 as usual when you share the battery with other devices.

You can even use wireless PowerShare when you are charging Galaxy S10 battery through a USB cable.  For example, you may have only one charger, but you need to charge both the phone and a Galaxy Watch.  In this case, you can connect the wall charger to charge the Galaxy S10 battery. At the same time,  you can use wireless PowerShare to charge the watch.

In a nutshell, Galaxy S10 wireless PowerShare adds a Qi wireless charger on the back of Galaxy S10. And the charger can use Galaxy S10 battery to charge other devices wirelessly.

Limitations of Galaxy S10 wireless PowerShare

Wireless PowerShare is very convenient, and it works with any devices that support Qi wireless charging.

FYI, most recent mobile devices including iPhone support Qi wireless charging. All Samsung gadgets with wireless charging support Qi wireless.

But wireless PowerShare has some limitations including:

• Charging speed is slow. There is no fast charging. The maximum charging capacity is 5W. The actual charging speed is substantially lower than this. So, Galaxy S10 wireless PowerShare is mainly designed for accessories like Galaxy Buds, Galaxy Watch. It may be a temporal solution of sharing the battery with other phones. If the other phone also has a USB C port,  you can charge it faster by directly connecting Galaxy S10 to that phone with a USB-C to USB-C cable.
• You may have to remove the covers or cases for Galaxy

In most regions, you can use two SIM cards on Galaxy S10, S10+, S10e, S20, S20+, and S20 Ultra if you choose not to use a micro SD card.

The dual-SIM version of Galaxy S10 can work in dual-standby mode.  The two SIM cards share (time-sharing) one modem and therefore the dual SIM version of Galaxy S10 does not support dual active mode.

This Galaxy S10 how-to guide explains how to use two SIM cards on Galaxy S10, S10+, S10e, S20, S20+, and S20 Ultra, how to enable and use dual SIM always on and how to use SIM card manager to set preferred SIM cards for calls, messages, and mobile data.

Please note, Galaxy S10 5G only supports one SIM card in all regions. So, in this guide, Galaxy S10 refers to Galaxy S10, S10e, and S10+ only.

Galaxy S20, S20+, and S20 Ultra (both 5G and 4G variants) have a dua-SIM version. You can also use two SIM cards on these phones. This guide also applies to these Galaxy S20 phones as well.

Who can use two SIM cards on Galaxy S10, S10+, S10e, S20, S20+, and S20 Ultra?

In most regions of Europe, Asia, Oceania, Africa, the Middle East, and Latin America, Galaxy S10 (except S10 5G) supports two SIM cards (dual SIM version).

You can use two SIM cards concurrently. In some countries, some carriers charge excessively for mobile data if the SIM card can also make calls. Some bundle very limited mobile data with voice plans. In this case, you can use one SIM card for calls, one for mobile data.

Or when travelling, you can use one SIM card issued in your home country and the other one from a local carrier. In this way will not miss important calls and messages without paying excessive roaming voice and data fees.

You can also use one SIM card for work-related communications, and the other for private affairs.

To use two SIM cards on Galaxy S10, you need to have a dual SIM version of Galaxy S10. As mentioned, unless you bought Galaxy S10 in North America, your Galaxy S10 (S10, S10+, and S10e) is very likely the dual SIM version.

How to check whether the Galaxy S10 is a dual SIM version or a single SIM version?

If you are not sure, check the IMEI number in Galaxy S10 Settings —About phone.

As shown in the screenshot below, if there are two IMEI (International Mobile Equipment Identity) numbers, it means it is a dual SIM version of Galaxy S10, and you can use two SIM cards.

Also, if the model number has a suffix of /DS as shown in the screenshot, it also indicates it is a dual SIM version of Galaxy S10.

Of course, on the box of Galaxy S10, the dual SIM version is usually stated as Duos.

For dual SIM phones, there are two variants: dual standby, and dual … Read the rest
