Top 10 new features in Android 10 update for Galaxy S10

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.

Native screen recorder

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

Samsung first introduced the native screen recorder in Galaxy Note 10. Now in 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 controls.

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 S1o after the Android 10 update.

More info from Device Care

Device Care now offers more information in most cards.

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

Tweaked Camera UI

Samsung is still not sure how a good camera UI should be. So, they change the camera app UI in almost every update.

In the Android 10 update, the change is not significant. The tweaks include:

You can edit the camera modes at the bottom of the screen (instead of navigation to Galaxy S10 camera settings).
You can tap the new

Galaxy S10 wireless charging guide

simon · Leave a Comment

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 on 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 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 convert 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 backward compatible.

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

You need 3 components to use wireless charging:

A phone supports wireless charging.
A wireless charging station.
An adapter supplying 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 (S10, S10+, … Read the rest

How to use Galaxy S10 night mode?

simon · Leave a Comment

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

How to use Galaxy S10 clear view cover (S-View flip cover)?

simon · 4 Comments

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

How to use Galaxy S10 Apps screen?

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:

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.
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:

Show or hide the apps button (marked as 1) using the switch.

How to use Galaxy S10 edge screen?

simon · Leave a Comment

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:

Edge lighting. You can use edge lighting the light up the edges of the screen when notifications arrive.
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.

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:

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

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

How to Use Galaxy S10 Always On Display (AOD)?

simon · Leave a Comment

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

How to use two SIM cards on Galaxy S10, S10+, S10e, S20, S20+, and S20 Ultra?

simon · 37 Comments

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

How to use Galaxy S10 virtual bezel to hide the front camera cutout without using any apps?

simon · 3 Comments

You can hide the front camera cutout on Galaxy S10, S10+, S105G, and S10e with the Galaxy S10 virtual bezel without using any third-party apps.

Samsung pinched an elongated hole for the front cameras to avoid a notch on the screen. And they proudly announced this trick as infinity “O” display. But some owners do not like this design.

This Galaxy S10 how-to guide explains how to use Galaxy S10 virtual bezel to hide the front camera cutout on Galaxy S10, S10+, S105G, and S10e, and the implications of using Galaxy S10 virtual bezel.

Why some owners do not like the front camera cutout?

Nowadays, all smartphone manufacturers try hard to increase screen size without increasing the overall size of the phone.

So, the size of the bezels decreases over the years. Samsung virtually eliminated the bezels on the sides with curved display since Galaxy S6.

On the bottom, Samsung removed the physical buttons and reduced the size of the bezel to the limit already.

So, on Galaxy S10, they tried to reduce the size of the bezel on the top further.

But there is a hard limit on the top: the front camera, notification LED, iris scanner, proximity, and light sensors all need spaces and cannot be hidden.

And Samsung made 2 stupid mistakes in reducing the size of the top bezel on Galaxy S10 (S10, S10+, S10 5G, and S10e):

The iris scanner was removed.
The notification LED was removed.

The hole punch for the front camera actually is not a bad idea, although some owners may prefer the notch design as in other Android phones or iPhones.

But what makes it wrong (or less ideal) is the location of the hole. On all Galaxy S10 phones, the hole is punched on the right side.

First, the hole destroys the symmetry of the front side. The ugly asymmetric look will be magnified when you use an app with a white background.

Second, the curved screen is used on Galaxy S10, S10+, and S10 5G. The hole must keep a certain distance from the curved part. This results in a significantly-reduced area for the status bar. So, Galaxy S10 has to offer the option for you to reduce the number of notification icons on the status bar or even hide/disable the notification icons on the status bar entirely.

Of course, some Galaxy S10 owners like the design.

Anyway, for those owners who cannot live with the look of the front camera cutout, it is easy to hide the front camera cutout without using any apps.

The truth is that Samsung already knew some owners would dislike the hole and therefore offered the Galaxy S10 virtual bezel to hide the front camera cutout.

The price you have to pay to hide the Galaxy S10 front camera cutout is slightly reduced screen size.

How to use Galaxy S10 screen zoom?

simon · 4 Comments

Galaxy S10 screen zoom allows you to scale the text and icons globally including the fixed-size text (e.g., notification text) that is not affected by font size settings.

Although Galaxy S10 screen zoom corresponds to display size in the stock Android, Samsung customized this feature a lot and they work quite differently.

This Galaxy S10 how-to guide explains when you need to adjust the Galaxy S10 screen zoom, and how to adjust it on Galaxy S10, S10e, S10+, and S10 5G.

What is screen zoom?

Google introduced the display size in Android Nougat (Android 7) for users to scale all display elements on the phone.

If you are using Windows PC, the display size in Android is similar to the scale (under display settings) on Windows.

Galaxy S10 screen zoom is based on display size in Android. But Samsung made significant customizations.

Compared to the display size in the stock Android, Galaxy S10 screen zoom works differently in the following aspects:

The screen zoom does NOT scale the app icons on Galaxy S10 Home screen, Apps screen, and lock screen.
The screen zoom has 3 levels. While the display size in Pixel phones has 5 levels.
The zoom levels in Galaxy S10 is quite moderate.

For the text and icons, the screen zoom works on all pages and apps, just like the display size in the stock Android.

Normally, the screen zoom is used together with the font size and style settings to get the desired look on the phone.

When do you need to change Galaxy S10 screen zoom? Why font size setting is not sufficient?

On Android, the size of some texts and display elements is hard-coded or fixed (based on DPI of the display).

For example, many Galaxy S10 owners complained about the small text size of the notifications. They tried to increase the font size. But the text size in the notification panel is not affected by font settings because it is fixed.

So, for such text (and icons), you will need to use the screen zoom to change the size.

In short, for most parts of Galaxy S10, the font settings are respected. But for the fixed-size text and icons, you have to use the screen zoom to adjust the display size.

How to adjust Galaxy S10 screen zoom?

You can change the screen zoom levels on Settings.

As shown in the screenshot below, on Galaxy S10 settings, tap Display to change the display settings for Galaxy S10.

In the Display settings page, as shown above, tap screen zoom.

Now in the screen zoom settings page, as shown below, you can find the 3-level slider.

You can drag it left or right to adjust the screen zoom level to small, medium, or large.

On the top part of the page, you can immediately preview the result of the setting. On Galaxy S10, Samsung only lets you preview the result in the Messages app.

As mentioned, the Galaxy S10 offers 3 … Read the rest

How to use Galaxy S10 home screen landscape mode for Home screen and lock screen?

simon · 2 Comments

You can use Galaxy S10 home screen landscape mode for the Home screen and lock screen on Galaxy S10, S10+, S10e, and S10 5G now.

When you hold the phone in the landscape orientation, both Galaxy S10 lock screen and Home screen can rotate so that you can use the landscape mode easily.

This Galaxy S10 how-to guide explains how to control the Galaxy S10 screen rotation, how to enable and use Galaxy S10 home screen landscape mode and Galaxy S10 lock screen landscape mode.

Different ways to control Galaxy S10 screen rotation (orientation)

On Galaxy S9 and S9+, Samsung introduced landscape mode for the home screen as explained in this guide.

Galaxy S10 keeps this feature and therefore you can enable the landscape mode for Galaxy S10 Home screen (including the apps screen)in a similar way.

Even better, Samsung also added the landscape mode for Galaxy S10 lock screen on all Galaxy S10 phones. Currently, this is a Galaxy S10 exclusive feature. So, the landscape mode for the lock screen is only available on Galaxy S10 phones.

On Galaxy S10, you can control the screen rotation in different ways:

You can turn on Auto-rotate so that the apps can change the orientation automatically when you rotate the phone. When Auto-rotate is on, you can exclude the Galaxy S10 Home screen and Lock screen.
You can turn off Auto-rotate (portrait mode) so that the rotation toggle appears when you rotate the screen. So, you can change and lock the screen orientation when you want. You may check this guide on how to use the screen orientation toggle here. When Auto-rotate is off, the rotation toggle will NOT appear on Galaxy S10 lock screen regardless of your lock screen rotation settings.

Please note, some apps may ignore the screen rotation settings. For example, Galaxy S10 camera app will not follow your screen rotation settings. When you rotate the screen, the camera app will always follow your rotation regardless of other settings.

How to enable and use the landscape mode for Galaxy S10 Home screen?

To use the Home screen in the landscape mode, you must enable it first.

You can enable the landscape mode for the Home screen in two different locations:

Galaxy S10 Settings
Galaxy S10 Quick settings.

In Galaxy S10 Settings, tap Display. Then, as shown in the screenshot below, on the Display settings page, tap Home screen.

As shown above, in the Home screen settings page, you can enable or disable “Rotate to landscape mode.”

You can also enable or disable Galaxy S10 Home screen landscape mode from Galaxy S10 quick settings.

As shown in the screenshot below, on the Galaxy S10 quick settings panel, tap the text, NOT the button/icon, of Auto Rotate.

If you disabled the auto-rotate, the Auto-rotate text should change to Portrait. In this case, tap the text (not the button) of Portrait.

Please note, the landscape mode for the Home … Read the rest

How to use Galaxy S10 Multi Window?

simon · 2 Comments

Galaxy S10 Multi Window allows you to run two apps side-by-side (split-screen view) or to overlap multiple apps over each other and other apps (pop-up view) to improve your productivity on Galaxy s10, S10e, S10+, and S10 5G.

Samsung changed and removed some multi-window features on Galaxy S10 with the updated Recents screen. Besides, Galaxy S10 Multi Window is significantly from that in the stock Android.

This Galaxy S10 how-to guide explains everything you need to know about Galaxy S10 Multi Window: what is it, the difference between the split-screen view and pop-up view, how to use the split-screen and pop-up views of Galaxy S10 Multi Window.

What is Galaxy S10 Multi Window?

By default, only one Android app can occupy the screen at any time, although Android is based on Linux, which of course supports multitasking on the desktop.

Google first introduced the multi-window (split-screen view) feature in Android Nougat.

But for Samsung Galaxy phones users, Multi Window had been introduced since Galaxy Note II in 2013.

And Samsung continued to polish this feature in each iteration of the Galaxy devices.

Galaxy S10 Multi Window allows you:

To run two apps side by side (split-screen view).
To let one or more apps floating over other apps and any screens (pop-up view). The size of the app window can be adjusted and even minimized. The stock Android does not support this even in the latest Android Pie.

Of course, you can use the split-screen view and pop-up view simultaneously.

What are the Multi Window features removed in Galaxy S10?

Unfortunately, Samsung removed some very useful features from Galaxy S10 Multi Window including:

Converting a normal app window to the pop-up view mode with a gesture. The diagonally swiping gesture is not supported on Galaxy S10. You cannot find the settings in Galaxy S10 settings anymore.
Directly converting split-screen view to pop-up view. When two apps are in the split-screen view mode, the only multi-window tool in Galaxy S10 is to resize the window. All other tools and options (e.g., app pair creation, Snap Window, swap apps) are removed in Galaxy S10 Multi Window.
Snap Window.
Multi Window (split-screen) icon was removed in the thumbnails in the Recents screen. You have to long tap the app icon in the Recents screen to use Galaxy S10 Multi Window feature.

Please note, these features were also removed in the Android Pie update for Galaxy S9 and S8.

If you still need these features, you need to install Samsung’s Good Lock app.

What are the differences between the split-screen view and pop-up view?

If you migrated to Galaxy S10 from other Android phones, you probably tried the split-screen view in the stock Android.

The most powerful feature of Galaxy S10 Multi Window is the pop-up view.

Basically, the split-screen mode allows you to run two apps side-by-side (in the long side). You can adjust the percentage of the screen for each app. … Read the rest

How to take screenshots on Galaxy S10 without using any apps?

simon · Leave a Comment

You can use at least 5 methods to take screenshots on Galaxy S10 without using any third-party apps.

Some screenshot-taking methods are unique to Galaxy S10 (and other Galaxy phones). Some are universal among all Android phones.

This Galaxy S10 how-to guide explains and shows the 5 different methods to take screenshots on Galaxy S10, S10e, S10+, and S10 5G.

What are the 5 ways to take screenshots on Galaxy S10?

On Galaxy S10 (all 4 Galaxy S10 variations), without using any third-party apps, you can use the following methods to take screenshots:

Use hardware buttons (volume down + power button).
Swipe your palm (palm swipe).
Use the Assistant menu.
Use Bixby Voice command.
Use Google Assistant.

Please note, although these are different methods to take screenshots on Galaxy S10, the result is identical except Google Assistant (read on).

Method 1: Use hardware buttons (volume down + power button) to take screenshots

On all Android phones, you can take a screenshot by pressing the holding Power button and Volume down button simultaneously.

This works on Galaxy S10 as well.

As illustrated below, you can simultaneously hold the power button and volume down button to take a screenshot on Galaxy S10. Please check Galaxy S10 layout for the location of physical buttons on S10 (S10e, S10+, and S10 5G).

Once the screenshot is taken, you will hear the click or shutter sound. If the smart capture feature is enabled in Galaxy S10 Settings — Advanced features, you will also see the toolbar on the bottom as well.

In old Samsung phones with a physical Home button, the physical home button was used with the power button to take screenshots. Because since Galaxy S8, Samsung has switched to on-screen (software) home button, you cannot use the Home button (with the Power button) to take screenshots on Galaxy S10.

The critical point of using physical buttons to take screenshots on the Galaxy S10 is to press the two buttons simultaneously.

As a human, we always press one button earlier than the other. It usually is OK to press the power button slightly earlier than pressing the volume down button. The power button accepts both single tap (press) and long tap gesture (for the power button options), and the long tap gesture will be triggered after you hold the button for about 2 seconds. So, as long as you hold the volume down button within 2 seconds (after holding the power button), you should be able to get the screenshot.

If you press the volume down button first, you will get the volume settings immediately because the volume down button only accepts the single press gesture.

After pressing the two buttons,

If you get the power button option, it means you press the power button too early.
If you get volume settings, it means you press the volume button too early.
If the screen is turned off, it means, you release the power button too early.

Lock screen. The lock screen is the first screen you will encounter after starting or wake up the phone. You need to unlock to access private data and apps.
Home screen. By default, after you unlock Galaxy S10, you will be directed to Galaxy S10 Home screen.
Apps screen. Traditionally, in Android phones, the apps screen is called app drawer, where you list all installed apps. Typically, only part of the installed apps is added to the home screen. Apps screen usually is considered as part of the Home screen,
Edge screen (for S10, S10+, and S10 5G only). As explained in Galaxy S10 layout, edge screen actually is a software feature, rather than a dedicated screen. The edge screen requires a curved edge of the display. Therefore, it is not available in Galaxy S10e due to its flat screen.
Recents (Overview) screen. You can find the list of recently used apps in the Recents screen. You can launch these apps in the split-screen view or pop-up view (multiwindow mode) as explained in this guide.
Notification panel. You can swipe down from the Galaxy S10 status bar to access the notification panel.

How to disable or customize the notification icons in the Galaxy S10 status bar?

simon · Leave a Comment

You can disable and customize notification icons in the Galaxy S10 status bar to save space for the status icons.

This Galaxy S10 how-to guide shows you how to limit the number of notifications icons in the Galaxy S10 status bar to 3, or to disable notification icons in the status bar.

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

Why you may consider to customize or disable notification icons in the Galaxy S10 status bar?

Due to the cutout of front cameras in the screen (see Galaxy S10 layout), the icons in the Galaxy S10 status bar are not aligned to the right edge of the screen. Instead, the status icons are aligned to the left side of the camera cutout (the left side of the O of the infinity O display).

Besides, since Android Pie update for Galaxy S9, Samsung displays the current time on the left side of the status bar like other Android phones.

Therefore, the usable space for the notification icons in the Galaxy S10 status bar is significantly reduced.

For example, as shown below, the default status bar can be very crowded if you show many notification icons. The meaning of the Galaxy S10 status icons and notification icons are compiled on this page.

Therefore, Samsung allows you to customize the number of notification icons shown on the status bar.

You can even disable notification icons in the Galaxy S10 status bar.

How to disable or customize the notification icons in the Galaxy S10 status bar?

If you want to customize the number of Galaxy S10 notification icons in the status bar or to disable notification icons in Galaxy S10 status bar, you can do so in Galaxy S10 Settings.

In the Settings page, tap Notifications, as shown below, to manage Galaxy S10 notifications.

In the notification settings page, as shown in the screenshot above, tap Status bar.

Now, in the status bar, you can see all options for customizing notifications icons in the Galaxy S10 status bar.

As shown below, you can choose to show:

3 recent notifications. If you have notifications from more than 3 apps, only the notifications icons from the last 3 apps will be shown.
All notifications.

The option of Shown battery percentage actually let you decide to show or hide the battery level on the right side of the status bar (among status icons, not notification icons).

As shown in the screenshot below, there is one notification icon. If you tap the switch for “Show notification icons” to turn it off it will hide the notification icon from the status bar.

As shown in the screenshot above, you can find the notification icon disappears after you disable notification icons in the Galaxy S10 status bar.

Please note, disabling notification icons in the status bar does not affect the notification itself. The corresponding notifications are still in the notification panel. The … Read the rest
