Modern smartphones have powerful processors and large displays, which allow users to perform multiple tasks simultaneously. The split screen function Android 11 is one of the key tools for increasing productivity while using the device. It makes it possible to view the news feed on social networks and at the same time respond to messages in the messenger or watch a video while reading an article.
Despite the fact that this option has become a standard, many gadget owners do not know how to activate it, since manufacturers often hide it in the depths of the menu or change the control gestures. In this material, we will analyze in detail all the ways to enable multitasking, customize the interface and solve common errors that users encounter when trying to launch two applications side by side.
The standard activation method is through the task menu
The most common method of launching split-screen mode is available directly from the application switching interface. This method works on most devices with a stock operating system and standard shells from major vendors. First, you need to open the desired application that you plan to use at the top of the display.
After that, swipe up from the bottom (or press the square button, depending on the type of navigation) to go to the recent tasks menu. Here you will see cards of all running apps. Find the icon of a specific application at the top of its card or next to the name.
Click on this icon to open the context menu. In the list of options, select Split screen (Split Screen). The system will automatically move the selected application to the upper half of the display, and at the bottom will offer to select a second application from the list of recently used or from the full list of installed apps.
- 📱 Click on the application icon in the recent tasks menu.
- 🔲 Select the "Split screen" option in the drop-down list.
- 👆 Tap a second application to fill the bottom area.
- ↔️ Drag the dividing line to resize windows.
Please note that not all apps support this feature. Developers can disable the ability to run in the background or in a smaller window for certain types of content, such as banking applications or graphics-intensive games.
If the app icon is not clickable or the Split Screen option is missing from the menu, then the developer has disabled the app from multitasking.
Using gestures for fast multitasking
For users who prefer control without buttons, the system Android 11 offers a convenient gesture interface. This method saves time and does not require unnecessary taps on the screen, which is especially important when using large smartphones with one hand.
To activate split-screen gesture, open the first application. Then swipe up from the bottom edge of the screen and hold your finger in the center of the display for a second until the recent tasks menu opens. Release your finger when you see application cards.
In the menu that opens, drag the card of the desired application up to the very edge of the screen or tap the icon above the card, if it is displayed. An alternative option on some shells, such as One UI from Samsung, involves swiping your finger from the side of the screen to the center and then holding it.
⚠️ Attention: Gesture sensitivity may vary depending on the device model. If the gesture does not work the first time, try changing the speed of your finger or the area of contact.
After successfully activating the mode, you will see a dividing line in the middle of the screen. It can be moved up or down, changing the proportions of occupied space for each application. This allows you to customize the interface for specific tasks, for example, by allocating more space for the video player.
Setting up additional windows and pop-up modes
In addition to the classic split screen in half, the operating system offers more flexible options for organizing the workspace. Pop-up window mode allows you to launch applications as small floating widgets on top of other apps, which creates the effect of true multitasking on your PC.
To activate this mode, open the recent tasks menu and click on the application icon. In the list that appears, select the option Open in a pop-up window. The application will collapse into a small rectangle that can be freely moved around the screen, resized and minimized to the bottom of the display.
This approach is especially useful if you need to quickly check information without closing the main application. For example, you can chat in a small messenger window while continuing to view photos in the gallery or edit documents.
| Window type | Occupied space | Moveability | Best use |
|---|---|---|---|
| Divided screen | 50% / 50% (adjustable) | No (fixed at top/bottom) | Data comparison, chat + video |
| Pop-up window | Small (about 20-30%) | Yes (free movement) | Calculator, notes, quick chat |
| Full screen mode | 100% | No | Games, watching movies, reading |
It is important to understand that the number of simultaneously running pop-up windows may be limited by the device manufacturer. Typically, the system allows you to comfortably work with two or three such windows without a significant drop in performance.
☑️ Checking multitasking support
Hidden functions and settings for developers
In some cases, standard settings do not allow you to activate split screen for all installed apps. To enhance the user experience, there are hidden options in the developer menu. Access to this section requires performing certain actions in the system settings.
To activate the forced split screen mode, go to Settings → About phone → Build number. Click on "Build Number" seven times in a row until a notification appears indicating that you have become a developer. After this, a new section will appear in the main settings menu For developers.
Inside this section, find the parameter Force to allow resizing (Force resizable activities). Activating this switch will allow you to run in split-screen mode even those applications that do not officially support this function by developers.
⚠️ Warning: Using experimental features may lead to unstable applications or the appearance of visual artifacts. Use these settings with caution.
Keep in mind that forcibly resizing the application interface may disrupt its layout. Buttons may become too small, text may be cut off, and some controls may become unclickable.
Risks of Using Developer Mode
Enabling hidden features can lead to increased battery consumption, as the system will spend more resources redrawing the interface of unoptimized applications. In addition, some banking applications may refuse to work if debugging mode is detected.
Compatibility issues and system limitations
Despite the versatility of the platform Android, the implementation of the multitasking function is highly dependent on the specific device manufacturer and version of the user shell. Users often encounter a situation where a function works perfectly on one smartphone, but is completely absent on another.
The main reason for the limitations is application optimization. Many apps, especially games and video players, dirancang exclusively for full-screen mode. Trying to run them in a reduced window may result in the app freezing or automatically closing.
There are also hardware limitations. Devices with a small amount of RAM (less than 3-4 GB) can automatically block the ability to split screen to prevent system overload and ensure stable operation of the main application.
- 🚫 Games often block multitasking to protect against cheating.
- 📺 Video players can mute the sound when minimizing the window.
- 🔒 Banking applications close when you try to split the screen for security reasons.
- ⚙️ Older smartphone models may not support the function in hardware.
If you are faced with the fact that the split screen button is inactive (gray), this is a direct signal that the current application does not support this mode. In this case, it is worth trying an alternative application with similar functionality.
The absence of a split-screen button is most often due to the policy of the application developer, and not a system error.
Solving common errors and failures
Sometimes users are faced with a situation where the split-screen mode is turned on, but one of the applications does not respond to touches or is displayed black screen. This may be due to a software version conflict or a temporary system glitch.
The first step to fix the problem should be to clear the cache of the problematic application. Go to Settings → Applications, select the desired app and press Storage → Clear cache. This action will not delete your personal data, but it will reset temporary files that may have caused the conflict.
If clearing the cache did not help, try restarting the device in Safe Mode. This will help determine if a third-party app is to blame for blocking the multitasking feature. To enter safe mode, you usually need to hold down the power button and then long press on the “Power off” item on the screen.
⚠️ Attention: The settings interface and the location of menu items may differ on smartphones of different brands. If you do not find the options described, check the official documentation of your device manufacturer.
As a last resort, if the problem is systemic and occurs in all applications, you may need to reset accessibility settings or even completely reset the device to factory settings. However, this measure should be resorted to only after creating a backup copy of all important data.
Before performing a hard reset, make sure that your Google account is synced so as not to lose contacts and calendar data.
Frequently asked questions (FAQ)
Why can't I share the screen with YouTube?
The official YouTube app often blocks background and split screen work for users without a Premium subscription. This restriction is imposed on the display of advertising. However, you can use the browser version of the site or third-party clients that do not have such restrictions.
Is it possible to run three applications at the same time on Android 11?
The standard interface allows you to place only two applications in split-screen mode. The third application can only be launched as a pop-up window on top of the two main ones, if your shell supports this function (for example, Samsung Pop-up View).
How to exit split-screen mode?
To exit the mode, just drag the dividing line to the very top or bottom edge of the screen. You can also press the Home button or task switch button, which will minimize both applications and return you to the home screen.
Does splitting the screen affect how quickly your battery drains?
Yes, running two active applications at the same time increases the load on the processor and RAM, which leads to faster battery drain. It is recommended to close unused applications after completing tasks.
Does split screen work in games?
Most modern games do not support this mode, as they require full capture of the device's resources to ensure smooth graphics. Trying to start a game in a split screen most often leads to its automatic closing or a severe drop in FPS.
