How to disable split screen on Android

Split screen mode, or Split Screenhas become an integral part of the modern mobile multitasking experience. This feature allows you to run two applications simultaneously, which significantly increases productivity when working with documents, viewing content, or communicating in instant messengers. However, this mode is not always convenient: on smartphones with small diagonals, the interface becomes too compressed, and accidental activation can irritate the user.

Often users are faced with a situation where one of the applications “gets stuck” at the top or bottom of the display, and standard navigation gestures stop working in the usual way. Understanding how to correctly exit this mode or completely deactivate it in the system settings is an important skill for comfortable use Android. In this material, we will analyze in detail all the ways to control multi-window mode.

It is worth noting that window operation algorithms can differ significantly depending on the version of the operating system and the manufacturer's proprietary shell. For example, the behavior of the menu on a “clean” one from Google will be different from the interface on Samsung devices or on Xiaomi smartphones. Therefore, it is important to take into account the specific features of your device when making settings. Android from Google will have a different interface One UI on Samsung devices or MIUI on Xiaomi smartphones. Therefore, it is important to take into account the specific features of your device when making settings.

Basic ways to exit split mode

The easiest and fastest way to close a split screen is to use standard navigation controls. If you use the classic buttons at the bottom of the screen, just press the key Home (usually the round button in the center). This action will minimize both active applications and return you to the home screen, ending the multitasking session completely.

For users who prefer gesture controls, the procedure is slightly different, but remains intuitive. You need to swipe from the bottom edge of the screen up to the middle to bring up the recent applications menu, and then swipe up on the card of one of the windows. An alternative is to simply drag the center dividing line all the way up or down to the edge of the display.

In some cases, especially on older versions Android, you may need to long press the Back button. This action forces the top or bottom app to close, leaving the second one on the entire screen. If none of these methods work, the app may be frozen and will require deeper system intervention through the Settings menu.

• 📱 Tap the Home button on the navigation bar to instantly exit.
• 🖐️ Drag the dividing line to the edge of the screen when controlling gestures.
• 🔙 Long press of the "Back" button closes the active window in split-screen mode.

Disable the feature in system settings

If you want to completely prevent the system from going into split-screen mode, you'll need to delve into the developer menu or special interface settings. On many modern smartphones, this option is hidden, as manufacturers consider multitasking a key feature. However, on devices with a clean Android or interface close to it, you can find a switch in the section System → For developers.

In the menu for developers, you need to find the item responsible for forced adaptation of applications. The required parameter is often called "Force applications to resize" or Force resize activities. Disabling this toggle will prevent unoptimized apps from running in windowed mode, although system applications can still use this feature. Be careful when changing these settings, as they affect the global behavior of the interface.

⚠️ Attention: Enabling or disabling options in the Developer menu may cause some applications to become unstable. If you notice any glitches, return the settings to default values.

The logic may be different on Samsung and Xiaomi devices. There is often no global switch here, but it is possible to disable split screen for specific apps. To do this, you need to go to Settings → Applications → [Select an application] → Advanced. If an application does not support multitasking, the corresponding menu item will be grayed out or missing.

Managing multitasking on different shells

Smartphone manufacturers are actively modifying the base code Android, creating unique user interfaces. This means that the path to disabling a feature can vary dramatically. For example, in the shell One UI from Samsung there is a separate menu for managing multi-window mode, while in MIUI the emphasis is on floating windows.

Owners of devices Huawei with the shell EMUI or HarmonyOS it is worth paying attention to the gesture settings. Split screen is often activated by swiping from the corner of the screen, and this can only be disabled by unchecking the corresponding checkbox in the gesture control menu. Ignoring this setting will result in the function triggering randomly when trying to open the notification panel.

Shell	Path to settings	Disable feature
Pure Android	Settings → System → For developers	Global toggle switch “Force resizing”
Samsung One UI	Settings → Display → Multi-window mode	Settings for specific applications
Xiaomi MIUI	Settings → Advanced settings → Gestures	Disable the swipe gesture from the corner
Huawei EMUI	Settings → Accessibility	Management via the sidebar

It is important to understand that software updates may change the location of these items. Interfaces evolve, and what worked in version Android 11can be moved to Android 13 or 14. If you don't find what you're looking for, search inside the settings menu for "split screen" or "multi-window."

Why don't manufacturers provide a simple "Off" button?

Smartphone manufacturers are promoting multitasking as a competitive advantage. Making it easy to disable this feature could reduce the perceived productivity of the device in the eyes of marketing, so the options are often hidden in deep menus.

Disable split screen for individual applications

Sometimes the user does not need to disable the feature completely, but only wants to disable it for certain apps. This is true for banking applications, games or video players that are not displayed correctly in the reduced window. In such cases, the system itself can block the separation, but sometimes manual configuration is required via adb or special utilities.

For advanced users, it is possible to use the command line ADB (Android Debug Bridge). By connecting your smartphone to your computer, you can enter a command that will forcibly prevent a specific package from running in split-screen mode. This requires USB debugging enabled and basic knowledge of working with a terminal, but gives maximum control over the system.

adb shell dumpsys window windows | grep -E'mCurrentFocus|mFocusedApp'

After receiving the package name of the desired application, you can apply a filter. However, it is worth remembering that some applications have built-in protection against such interference. If the app considers split-screen mode a security risk (for example, when entering a PIN code), it will minimize itself to full-screen mode, ignoring system settings.

• 🔒 Banking applications often block split-screen automatically for security reasons.
• 🎮 Games with landscape orientation may be distorted when running in a window.
• ⚙️ Using ADB requires enabling USB debugging in the developer menu.

Solving problems with freezing windows

One of the most common problems is the situation when the application does not close and continues to occupy half the screen, even after trying to exit. This is a software glitch that is often resolved by restarting the interface. If simply restarting your smartphone does not help, you can try clearing the cache of the system process responsible for recent applications.

To do this, go to Settings → Applications → Show system processes. Find the application responsible for the interface (often it is called System UI or has a shell name, for example One UI Home). In the menu of this application, select "Memory" and press Clear cache. Do not confuse this with clearing data, as it will reset all desktop and widget settings.

⚠️ Attention: Clearing system application data (not cache) will reset the arrangement of icons on the desktop and delete saved interface settings. Perform this action only as a last resort.

If the problem is persistent and occurs with different applications, third-party software may be to blame. Launchers installed on top of the standard shell or window management utilities may conflict with system settings. Try temporarily disabling or removing recently installed apps that affect the appearance of the system.

Alternative solutions and floating windows

Instead completely abandoning multitasking, it is worth considering an alternative in the form of floating windows. This mode allows you to run an application in a small window on top of another, which is often more convenient than hard splitting the screen in half. In most modern shells, this function is activated from the recent applications menu by clicking on the app icon.

The floating window can be freely moved around the screen, changed its size or minimized into a bubble. This gives flexibility, which the regime lacks Split Screen. If your goal is to free up screen space and not to prohibit multitasking as such, using floating mode will be the best solution. It is less demanding on display resolution and does not “cut” content in half.

Some users prefer to use the sidebar for quick access to applications. In the interface settings, you can activate the panel that slides out from the side. From there, you can drag an application onto the screen, and it will automatically open in floating mode. This is a convenient compromise for those who want quick access to a calculator or instant messenger without closing the main application.

Frequently asked questions (FAQ)

Why is the split screen button grayed out in the recent applications menu?

This means that the selected application does not support multitasking. The app developer may have explicitly prohibited this function in the application manifest, or the version Android on your device is too old to support this app in windowed mode.

Is it possible to split the screen into three parts at the same time?

Using standard means Android split the screen by more than two applications are not possible. However, some manufacturers, for example, Samsung in DeX or on tablets, provide advanced capabilities for creating complex window layouts, but on regular smartphones the limit is two windows.

Does the split-screen mode affect the speed of the smartphone?

Yes, the simultaneous operation of two active applications increases the load on the processor and RAM. On devices with less than 4 GB of RAM, this can lead to noticeable stuttering and faster battery drain.

How to return all applications to full screen after a crash?

If the system “remembers” an incorrect state, the most reliable way is to completely reboot the device. You can also try switching the screen orientation from portrait to landscape and back, which often forces the system to redraw the interface correctly.

Will the sound in one of the applications turn off when splitting the screen?

The behavior of the sound depends on the OS version. In modern versions Android sound can be played only from the active window, or mixed. In some cases, the system automatically pauses the video in an inactive window to avoid overlapping audio streams.
