Dividing the screen on Xiaomi Redmi 10: 4 working methods + error solving

Xiaomi Redmi 10 is one of the most popular budget smartphones with extensive multitasking capabilities. Split-screen allows you to work with two applications simultaneously, such as texting in the messenger and watching videos, comparing prices in the browser or copying text between documents. However, many users face difficulties in activating this mode – especially after MIUI updates or resetting settings.

In this article, you will find 4 proven ways to enable screen splitting to Redmi 10 (including hidden developer settings), application compatibility table, and solutions to typical errors - from the absence of a multi-window button to the interface freeze. Instructions are relevant for all firmware versions: MIUI 12, 13 and 14 (including global and Chinese builds).

1. Standard method: gesture or button in the application menu

The easiest way to activate split screen is to use the built-in MIUI tools, which work out of the box and doesn't require superuser rights.

1. Open the first app you want to place at the top of the screen (like YouTube or Chrome).

2.Click on the "Recent Apps" button (square in the navigation bar) or swipe up from the bottom edge of the screen and hold your finger for 1 second.

3. At the top of the screen will appear the app icon – tap it and select the option “Share the screen” (or “Split screen” in English firmware).

If there is no section for the screen:

• 🔧 Check if the application supports multi-window (the list of compatible programs is in the next section).
• 📱 Make sure you have gesture navigation enabled (in Settings → Display → Navigation Bar).
• 🔄 Reboot your smartphone – sometimes the feature disappears after updates.

Once activated, the top of the screen will lock, and the bottom will become translucent — you need to select the second app from the recent list or from the main screen. To change the size of the windows, pull the dividing line in the center.

💡

If the dividing line doesn’t move, try pulling it by the gray circle in the center – in some versions of MIUI, it is the one responsible for resize.

Application compatibility: which programs support split-screen

Not all applications on Xiaomi Redmi 10 can work in split-screen mode, depending on the developer’s policy and Android restrictions.

Important: Banking apps (SberBank, Tinkoff) and some messengers (for example, Viber) can block screen splitting for security reasons. If the program does not support multi-window, try using its web version in the browser.

To check the compatibility of a particular application:

1. Open it in split screen mode (as described in the first section).
2. If the content is displayed in place of a black screen or a notification “App does not support multi-window”, then the function is blocked.
3. Try to update the program through Google Play – sometimes support is added in new versions.

3. Alternative method: developer settings

If the standard method doesn't work, you can enable splitting of the screen through the developer's settings, which requires the hidden menu to be activated beforehand:

1. Go to Settings → About the phone.

2. Find the MIUI version and tap it 7 times in a row (the notification will appear "You became a developer").

3. Go back to the main settings menu and open a new Developer section (usually at the bottom of the list).

In the developer menu, find the options associated with the multi-window:

• 🔄 Enable free multi-window shape – allows you to change the size of the windows arbitrarily.
• 📱 Forced split-screen – causes incompatible applications to open in split mode (may cause errors!).
• 🔧 Show the multi-window button — adds an icon to the recent app panel.

Once you activate the options, try splitting the screen again in the standard way, and if the app still doesn't open in the multi-window, then the developer has clearly blocked the feature at the code level.

💡

Enabling the developer mode does not void the warranty, but changing certain parameters (e.g., Forced split-screen) can lead to unstable system performance.

4. Problem Solving: Why Screen Split Doesn't Work

If the split-screen refuses to turn on, the reasons can be different — from firmware bugs to conflicts with other functions.-5 errors and their solutions:

Problem 1: There is no split screen button in the menu of recent apps.

• 🔧 Switch from gesture navigation to buttons in Settings → Display → Navigation Bar.
• 📱 Update your firmware to the latest version (in Settings → About Phone → System Update).
• 🔄 Reset MIUI to factory settings (without deleting data) in Settings → Additional → Reset settings.

Problem 2: The application opens in a multi-window, but it closes immediately. Solution: This is typical for programs that don't support background work (such as some games).

• 🛠️ Disable battery optimization for this application in Settings → Applications → Application Management → Battery → Battery Optimization.
• 🔧 Enable the No Limits mode for the application in the battery settings.

Problem 3: The dividing line is not moving. Solution: In some versions of MIUI, you need to resize the windows:

1. Press and hold the dividing line for 2 seconds.
2. Pull the gray circle in the center of the line (if any).
3. Reboot your phone – sometimes the interface “wilts”.

💡

If one of the applications stops responding to touch after splitting the screen, try rolling the multi-window (pulling the dividing line to the edge of the screen) and deploying it again.

Problem 4: Split-screen only works in horizontal orientation. Solution: It's a constraint of Android -- some apps (like Instagram) block vertical separation.

• 🔄 Turn the screen autorotate in the notification curtain.
• 📱 Use a launcher app (like Nova Launcher) that supports forced rotation.

⚠️ Warning: If after the MIUI update the screen split is gone completely, check if your Redmi 10 has a firmware beta installed. In test builds, the feature is often disabled. Return to stable version via Settings → About Phone → System Update → Three Dots → Service Pack selection.

5. Additional chips: gestures and third-party utilities

In addition to standard methods, Xiaomi Redmi 10 can use alternative ways to control the multi-window:

Method 1: A gesture for quick separation

In some versions of MIUI, a hidden gesture works:

1. Open the first appendix.
2. Swipe your finger from the lower right corner of the screen up diagonally (as if drawing a line to the upper left corner).
3. The screen will split and you can select the second app.

Note:

Method 2: Applications for forced split-screen

If the built-in tools are not satisfied, install from Google Play:

• 📱 Split Screen Launcher – Adds the multi-window button to the home screen.
• 🛠️ Multi Window – allows you to create up to 4 windows at a time (requires rights ADB).
• 🔧 Taskbar – Emulates the taskbar as on a PC, with support for drag and drop windows.

Method 3: ADB- Instructions for forced inclusion

For advanced users: If the application blocks split-screen, you can try to enable it forcefully via ADB:

adb shell settings put global force_split_screen true

After completing the command, restart your smartphone. Careful: this can lead to unstable operation of incompatible programs!

6. Optimization of performance in multi-window mode

Splitting the screen will strain the Redmi 10’s processor and RAM, especially if heavy applications (such as games or video editors) are running simultaneously.

Advice 1: Close the background processes

Before split-screen activation:

1. Open Settings → Applications → Application Management.
2. Click on the three dots in the top right corner and select Clean All.
3. Close all unused programs in the recent menu.

Advice 2: Turn off animation

Reducing the animation of the interface will reduce the load on the processor:

• 🔧 In the Developer Menu, find:
• Select the scale of the animation window → No animation.
• The scale of the transition animation → Without animation.
• Duration of the animator → Off..

Advice 3: Use the "Light Mode"

MIUI has an optimization mode for weak devices:

1. Go to Settings → Special Opportunities → Easy Mode.
2. Turn on the option and select Optimize for Multitasking.

⚠️ Warning: If Redmi 10 starts to warm up a lot in split-screen mode, check if the background is running resource-intensive processes (e.g. downloading files or streaming videos). Temperatures above 45°C can lead to trolling (automatic performance decline).
