How to make a screen split on Xiaomi Redmi: all ways + bug fix

The split-screen feature on Xiaomi Redmi smartphones allows you to work with two applications simultaneously – for example, chatting in the messenger and watching videos, or copying text from the browser into notes. Despite the obvious benefits, many users face difficulties in activating this mode: someone can not find an option in the settings, others have multi-windows that malfunction, and some models do not have the function “out of the box”.

In this article, we’ll look at all the current ways to enable split screen on Redmi Note 12/13, POCO X5/F5, Redmi 10C/12C and other devices running MIUI 14/15 (including global and Chinese versions of firmware).

1. Standard method: split screen gesture in MIUI

The easiest method is to use a built-in gesture that works on most Xiaomi devices with MIUI 12 and later.

1. Open the first app you want to pin to the top of the screen (like YouTube or Chrome).
2. Click on the “Recent Apps” button (square in the bottom navigation bar or swipe up with a 0.5 second delay).
3. In the list of open applications, find the icon of the first application, pinch it with your finger and drag it to the top of the screen.
4. The screen will split into two parts. In the lower half, select the second app from the recent list or run it through the main menu.

If the gesture doesn't work, check:

• 🔹 Version MIUI: firmware MIUI 11 the function may not be available.
• 🔹 Smartphone model: on some budget Redmis (for example, Redmi) 9A/10A) multi-window disabled by default.
• 🔹 Sign settings: c Settings → Display. → Full screen mode should be selected Gesture mode, not Buttons.

2. Activation through developer settings (for hidden function)

On some Xiaomi models (especially budget ones), the screen split is hidden in the developer menu.

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times. You will be notified “You are a developer”.
2. Return to the main settings menu and open Additional settings → Developer settings.
3. Scroll down to the Drawing section and find the option force_resizeable_activities (Or forced resizing of activity. Turn it on.
4. Also activate the option. force_enable_multi_window (if).
5. Reboot your smartphone.

Then try splitting the screen again through a gesture (see first method).

• 🔧 Application compatibility: Not all programs support multi-window (e.g., some games or banking applications).
• 🔧 Updates MIUI: On older versions of the firmware, the option may not work properly.

3. Screen splitting via the "Recent" button (alternative method)

If the gesture doesn’t work, try another way:

1. Open the first app (e.g. Telegram).
2. Press the “Recent” button (square or swipe up).
3. At the top of the screen will appear the icon of the application – click on it (do not pinch!).
4. In the context menu, select Split Screen (or Split Screen on global firmware).
5. Select the second app from the “Recent” list or run it manually.

If the option "Share the screen" is not in the menu, it means:

• 📱 The firmware does not support the function (relevant to Redmi). 8/9 older versions MIUI).
• 📱 The application is blocked for multi-window (for example, Netflix or TikTok).

💡

If the split screen is not running smoothly, try turning off the power saving for both applications in the battery settings, which will prevent one of the windows from spontaneously closing.

4.Why Screen Split Doesn't Work: Typical Problems and Solutions

• 🎮 Games (PUBG, Genshin Impact – often disable split screen to prevent cheating.
• 🏦 Banking applications (SberBank, Tinkoff) – can block the function for security reasons.
• 📺 Streaming services (Netflix, Disney)+) — Sometimes limit multi-windows to protect content.

5.Sharing the screen on Xiaomi using third-party apps

If the built-in methods don't work, you can use specialized utilities from Google Play.

• 🔧 Split Screen Launcher -- creates a shortcut for fast split screens. MIUI 12-15.
• 🔧 Multi Window Mode – emulates multi-window via window overlay (requires rights) ADB).
• 🔧 Floating Apps – allows you to open applications in floating windows (alternative to splitting).

1. Install the app from Google Play.
2. Open it and select Create Shortcut.

By default, the screen is split in half, but you can change the proportions:

1. In multi-window mode, find the dividing line between the two apps (usually gray).
2. Hold your finger and drag it up or down to enlarge one of the windows.
3. Release your finger when you reach the right ratio (for example, 70%/30%).

Limitations:

• 📏 Minimum window size – 20% of the screen (on some models – 25%).
• 📏 Some apps (such as Google Maps) do not allow you to change the size of the window.

If the dividing line does not move:

⚠️ Note: On the Redmi Note 10 Pro and some other models, with horizontal screen orientation, window size change can be blocked.

💡

MIUI 15 now allows you to save frequently used multi-window app pairs, and in split-screen mode, click three points in the dividing line and select Save the combination.

7.Separate the screen to Xiaomi using ADB (advanced method)

If none of these methods worked, you can force the multi-window to be enabled via ADB. This method is suitable for power users and requires a computer.

Instructions:

1. Download and install Platform Tools (or Minimal ADB and Fastboot) on PC.
2. Enable USB debugging on your smartphone: Settings → About Phone → MIUI version (7 times), then Additional settings → Developer options → Debugging over USB.
3. Connect your phone to your PC and type in the command line: adb shell settings put global force_resizeable_activities 1
4. Reset the device.
