How to completely disable screen splitting on Xiaomi: 4 proven ways

The multi-window feature on Xiaomi smartphones can be useful for working with multiple apps at the same time, but it often turns on accidentally or interferes with video, games, and even calls. If you notice that the screen spontaneously divides into two parts, and the inscription “Multiwindow” appears in the top panel – this is a sign of an activated feature. In this article, we will discuss all the ways to completely turn it off, including hidden MIUI settings, which work even on the latest versions of the firmware in 2026.

Compounding the problem, Xiaomi’s different models (like the Redmi Note 12 Pro+, POCO F5, or Black Shark 5) may have different paths to settings, we tested the instructions on devices with MIUI 12-14 and identified universal methods that will work 95% of the time, and we’ll also explain why splitting the screen can turn on on on itself after a firmware update and how to prevent this.

Why does Xiaomi have a split screen?

The multi-window function is activated not only manually, but also for a number of other reasons:

• 🎮 Control gestures: on MIUI Swipe up from the bottom edge with a delay can trigger split mode. This is a common problem for users accustomed to standard Android gestures.
• 📱 Update of the firmware: after update to MIUI 13/14 Multi-window settings are reset to default values (included for all applications).
• 🤖 System bugs: on some models (e.g. Redmi) 10C or POCO X3 Pro) the function is spontaneously activated when connected to Mi Share or Bluetooth devices.
• 🔄 Reset: After hard reset, the multi-window is automatically activated if previously activated.

Another common situation is splitting the screen when watching YouTube or Netflix, which is because the multi-window function conflicts with the full-screen gestures, and in these cases, switching off through settings doesn't always help, and deeper adjustments are required.

Method 1: Disconnecting with Special Opportunities (on 90% of devices)

The most reliable method is to deactivate the feature in the special features section, which works even on custom firmware and devices with MIUI for the global market (EEA).

1. Open the settings (cog icon).
2. Go to Special Features → Usability → Screen Sharing.
3. Move the slider to the off position.
4. Confirm the action by pressing OK in the window that appears.

If there is no “Share Sharing” option on the menu, try an alternative path:

Settings → Additional → Functions Laboratory → Multi-window

Important: Some devices (e.g. Xiaomi Mi 11 Ultra) may need to reboot after the feature is disabled, as the changes don’t apply instantly. If split screen is still working, move on to the next way.

Method 2: Customize gestures (for users without the Home button)

If you use navigation gestures (without the classic buttons), splitting the screen may be triggered due to a conflict with the system gestures.

1. Go to Settings → Display → Full-screen mode.
2. Select navigation gestures (or MIUI-gestures on older versions).
3. Scroll down and find the option "Separate screen gesture".
4. Turn off the slider next to this option.

Nana POCO-The path of the devices may differ:

Settings → System → Gestures → Additional gestures → Multi-window

💡

If the split screen still works after the gestures are turned off, try switching to the navigation buttons (three dots at the bottom of the screen) and checking if the problem persists, which will help determine if the bug is related to the gestures.

On Black Shark and Xiaomi gaming smartphones, the multi-window feature can be tied to Shoulder Key to turn it off:

Settings → Game functions → Shoulder Key → Disable Multiwindow

Method 3: Reset multi-window settings (if the function is not disabled)

If previous methods failed, it is possible that the multi-window settings have been changed at the system level, in which case only resetting the split-screen settings without losing personal data will help:

1. Open Settings → Applications → Application Management.
2. Click on the three dots in the upper right corner and select Show System.
3. Find the Multiwindow app (or MultiWindow in English firmware).
4. Select Warehouse → Clear data and Clear cache.

After that, the function will be reset to factory settings and it can be disabled in the standard way (see Method 1).If the Multiwindow application is not on the list, try an alternative method:

Settings → Memory → Cleaning → Deep Cleaning → Select “System settings” → Confirm

Method 4: Disconnect via ADB (for advanced users)

If standard methods do not work, you can turn off the split screen through ADB-This is a good way to use devices with unlocked bootloaders or root rights, but it works on some models without them:

• 🖥️ A computer with installed Xiaomi drivers and ADB Tools.
• 📱 Included Debugging by USB on a smartphone (Settings) → The phone. → Version. MIUI — Press 7 times, then return to Additional → For developers).
• 🔌 USB-cable (preferably original).

Instructions:

1. Connect your smartphone to your PC and open the command line (cmd on Windows or Terminal on macOS/Linux).
2. Enter the command to check the connection: Adb devices must appear serial number of your device.
3. Execute the multi-window shutdown command: adb shell settings put global multi_window_mode_off true
4. Reboot your smartphone: adb reboot

If the function is still active after the reboot, try an alternative command:

adb shell pm disable-user --user 0 com.miui.multitask

💡

Using ADB is the most reliable way to disable system-level splitting, but it requires caution. Wrong commands can disrupt your smartphone. If you're not sure what you're doing, you'd better turn to other methods.

Table: Compatibility of methods with different models Xiaomi

If your model isn't in the table, try Method 1 or Method 4, which is the most versatile. MIUI China (CN-version) may require additional region adjustment or firmware for the global version.

What if the screen splits on its own?

If the function is activated without your participation, the reason may lie in:

• 🔄 Automatic updates MIUI: After the update, the settings are reset. Check the update history in Settings → The phone. → Updating the system.
• 🤖 Application conflict: Some programs (such as Parallel Space or Game Turbo) force multi-window activation.
• 📱 Damage to system files: If the smartphone fell or overheated, it could have caused crashes. check firmware integrity through Settings → The phone. → Diagnostics.

For diagnosis:

1. Run Safe Mode (press the power button → “Safe Mode”).
2. Check if splitting is enabled in this mode, and if not, the problem is in third-party software.
3. Remove the recently installed apps until you find the culprit.

If the problem occurred after the fall of the smartphone, check the proximity sensor and gyroscope with the test # # # # #6484## (dial in the dialer).
