Dividing the screen on Xiaomi Redmi Note 8: how to turn on and use the multi-window

The split-screen (or multi-window) feature on the Xiaomi Redmi Note 8 allows you to work with two apps simultaneously โ€” for example, watching YouTube videos and chatting in the messenger. This feature is especially useful for owners of smartphones with large screens, where space can be efficiently distributed between tasks. However, not all users know how to activate this mode correctly, since depending on the version of MIUI, the path to settings may differ.

In this article, weโ€™ll look at all the ways you can enable split screen on the Redmi Note 8, including gesture controls, button combinations, and hidden system settings. Youโ€™ll also learn which apps support multi-window, how to resize windows, and what to do if the feature doesnโ€™t work. If you use your smartphone frequently for multitasking, this guide will help optimize your experience.

What is Screen Sharing and Why You Need It

Split Screen is a feature that divides the smartphone display into two independent areas, each of which can open a separate application. On the Xiaomi Redmi Note 8, this option works thanks to the MIUI firmware, which supports multi-window mode starting with the version of MIUI 8.

The main advantages of the function:

  • ๐Ÿ“ฑ Multitasking: Simultaneously working with two applications (for example, maps and messenger).
  • ๐ŸŽฅ Easy viewing: you can watch videos and read comments or correspondence in parallel.
  • ๐Ÿ“ Data portability: copying text or files between windows without switching.
  • ๐ŸŽฎ Games and chats: play and communicate in Discord/Telegram pauseless.

However, not all apps support split screens, for example, some games or banking programs may block multiwindow for security reasons, and it is worth considering that the Redmi Note 8 with a 6.3 screen is less convenient to work with two windows at the same time than on tablets or smartphones with displays from 6.7.

Step-by-step:

  1. Open the first application you want to use in multi-window mode.
  2. Click on the โ€œRecentโ€ button (square in the bottom navigation bar) or swipe up with a delay (if you use gesture control).
  3. In the list of recent apps, find the app icon you want to open in the second window and hold it for 1-2 seconds.
  4. In the menu that appears, select "Separate Screen" (or "Open in split mode").
  5. Select the second app from the list or from the home screen.

And then the screen splits into two, and you can interact with both apps, and to swap them, just drag the dividing line up or down.

  • ๐Ÿ”ง Settings โ†’ Additionally. โ†’ Functions laboratory (enable "Screen splitting").
  • ๐Ÿ”ง Settings โ†’ Screen. โ†’ Screen splitting (in some regional firmware).
What to do if the settings do not include the "Share split" item?
If you donโ€™t have a multi-window option on your menu, this could mean: 1. You have an outdated version of MIUI installed (update the firmware). 2. The manufacturer has disabled the feature for your region (try changing the region in the settings). 3. Use a lightweight version of MIUI (e.g. MIUI Lite) where the multi-window is not available. In this case, try activating the mode through the developer settings (see next section).

Method 3: Including through the developer settings

If standard methods donโ€™t work, you can try to activate split screens through developer mode, which is suitable for advanced users and requires caution, as incorrect settings can affect the stability of the system.

Instructions:

  1. Activate Developer Mode: Go to Settings โ†’ About Phone. Click on MIUI Version 7 times in a row until the notification โ€œYouโ€™ve become a developer!โ€ appears.
