Dividing the screen on Xiaomi Redmi 9: all ways and settings

Introduction: why you need Split Screen on a smartphone

The split screen feature on Xiaomi Redmi 9 allows you to use two apps at the same time – for example, watching YouTube videos and chatting in the messenger, or copying text from the browser to a document. It is not just a “chip” for geeks, but a useful tool for multitasking that saves time and simplifies work with several tasks.

On Redmi 9 (and other Xiaomi smartphones based on MIUI 12/13/14), split screen mode is implemented at the system level, but not always on by default. Many users do not even know about its existence - and it is in vain! In this article, we will discuss all the ways to activate, customize and solve typical problems.

Important: Split Screen features depend on the MIUI version and the updates installed. If your Redmi 9 runs on old firmware, some features may not be available. Update before you start setting up!

Method 1: Standard Separation through Multitasking

The easiest method is to use the built-in feature of recent applications, which works on all versions of MIUI (12 and above) and does not require additional settings.

Instructions:

1. Open the first app (like Chrome) you want to pin to half the screen.
2. Click the square button at the bottom of the screen (or swipe from the bottom up and hold your finger to call the menu of recent apps).
3. In the list of open applications, find the icon of the first application and press it for 1-2 seconds.
4. In the menu that appears, select Divide Screen (or Split Screen in English version of MIUI).
5. The screen will split into two parts, and at the bottom you'll see a list of compatible apps. Choose the second.

Now both apps are running simultaneously, and to swap them, just drag the dividing line up or down.

Method 2: Quick separation gestures (MIUI 13/14)

Newer versions of the firmware have a more convenient way, gesture control, which allows you to split the screen in two touches without opening the multitasking menu.

How it works:

1. Open the first app (e.g. Telegram).
2. Swipe your finger from the bottom edge of the screen up and hold for 0.5 seconds, and the recent app panel will open.
3. Without letting go of your finger, drag the app icon upwards (to the top half of the screen).
4. Release - the application will be fixed, and the list will open from below to select the second.

This method does not work on all versions of MIUI. If the gesture does not work, check the settings:

1. Go to Settings → Special features → Gestures.
2. Make sure the option of splitting the screen by gesture is enabled.

Method 3: button in the notification bar (hidden function)

Few people know, but Redmi 9 can add a special button for quick split-screen right into the notification curtain, eliminating the need to open multitasking every time.

How to set up:

1. Deploy the notification panel (swipe top-down twice).
2. Click on the icon. ⚙️ Settings (or Editing).
3. Find the Screen Split (or Split Screen) switch in the list and drag it to the active area.
4. Save the changes.

Now, when the application is open, it is enough to turn the curtain and press the new button - the screen will immediately split, and you will only have to choose the second application.

If the split screen button is not in the switch list, upgrade to the latest version of the MIUI or use alternative methods from this article.

What apps support Split Screen on Redmi 9?

Not all programs can run in split-screen mode, and the system automatically blocks applications that:

• 🔒 Requires full screen mode (for example, most games or banking applications).
• 📱 Not optimized for MIUI (These are often little-known programs from third-party sources).
• 🔄 Use secure protocols (for example, some encrypted messengers).

Here is a list of popular apps that are guaranteed to support Split Screen on Redmi 9:

If the app you want doesn’t support the mode, try updating it or using an alternative (for example, instead of Instagram, open the web version in your browser).

Size setting of windows and separation management

• 📱 In some versions MIUI Floating window – a miniature version of the application on top of others (activated by long-term retention of the icon in multitasking).

1. Open the Settings → Screen → Autoturn.
2. Turn off the option or block the current orientation.
