The multi-window feature on Xiaomi Redmi 9A allows you to use two apps simultaneously β for example, watching YouTube videos and chatting in the messenger. Despite the budget stuffing, the smartphone supports this mode, albeit with some limitations. In this article, we will analyze all the available activation methods, finer settings and typical errors that users encounter.
It is important to understand that Redmi 9A is based on MIUI with Go Edition shell (simplified version for weak devices), so the classic multi-window mode may be absent or require additional manipulation. We tested all methods on current firmware versions (including MIUI 14) and collected only working solutions.
Method 1: Split the screen through the βRecentβ button
The simplest and most formal method is to use the recent app dashboard, which works on most versions of MIUI, but requires both apps to be pre-launched.
Step instructions:
- π± Open the first app (like YouTube), then roll it up with the Home button.
- π Launch a second app (like Telegram) and also fold it.
- π Click on the square button Recent (or swipe up and hold to call the menu).
- π Find the first app in the list, click on its icon (not the preview!) and select βSeparate screenΒ».
- π Go back to the recent list and select the second app β it will automatically open at the bottom of the screen.
If the βSeparate Screenβ option is missing, then your version of MIUI does not support it β move on to the next method.
Launch both applications in advance
Make sure that the developer mode is enabled in the settings (if you need an alternative method)

2. Method 2: Using the Developer Mode
On some Redmi 9A firmware, the multi-window function is hidden and requires activation through developer settings, a method that is suitable for advanced users, as incorrect actions can affect system stability.
How to turn on:
- Go to Settings β About Phone and 7 times click on the MIUI Version to unlock the Developer Mode.
- Go back to the basic settings and open a new section for developers.
- Find the Multi-window or Force Resize Activities setting and activate it.
- Reset the device.
Then try splitting the screen again through the recent app bar, and if the feature never came up, check for MIUI updates or use the third method.

If after activating the developer mode, the smartphone began to slow down, turn off the option Do not turn off the screen in the same settings - it often conflicts with the multi-window.
Method 3: Applications for Forced Separation
When the standard methods don't work, third-party utilities come to the rescue. - For Redmi 9A fit:
- π§ Split Screen Launcher β Creates a shortcut for fast screen splitting.
- π₯οΈ Floating Apps β allows you to open applications in floating windows (alternative to multi-window).
- π Multi Window β emulates split mode even on incompatible firmware.
How to use:
- Download one of the apps from Google Play (check reviews β some utilities may contain ads).
- Run it and provide the necessary permissions (e.g. Overlay over other windows).
- Select applications to be split through the utility interface.
Important: Third-party apps may conflict with MIUI Go Edition due to Redmi 9Aβs limited resources (only 2GB of RAM).If the smartphone starts to slow down, close the background processes or use lightweight versions of apps (for example, YouTube Go instead of regular YouTube).

4. Screen splitting setting: subtleties and limitations
Even if you managed to activate the multi-window, there are a number of nuances on the Redmi 9A:
| Parameter | Limitation | Decision |
|---|---|---|
| Screen resolution | Maximum 720p (1560Γ720), which reduces the workspace | Use apps with a responsive interface (e.g. Chrome) |
| Productivity | Lags with simultaneous operation of two βheavyβ applications | Close background processes through Settings β Applications |
| Compatibility | Not all apps support multi-window (such as some games) | Check compatibility on Google Play before installing |
| Management | There is no way to change the proportions of windows (fixed 50/50) | Use third-party launchers (like Nova Launcher) |
To change apps in places, pull the dividing bar up or down. To exit the multi-window mode, swipe the bar to the edge of the screen or press the Home button.
