How to split the screen Xiaomi Redmi 9C: the full guide

Multitasking in modern smartphones has ceased to be just a marketing term, becoming a real necessity for most users. The owner of the budget but popular Xiaomi Redmi 9C, often faces the need to simultaneously chat in the messenger and watch videos or compare products in the online store. The standard MIUI interface installed on the device provides powerful tools for organizing the workspace, but their activation is not always obvious for beginners.

In this article, we will discuss in detail all the available ways to activate Split Screen mode on your gadget. You will learn how to use system gestures, navigation buttons and third-party utilities for comfortable work. We will pay special attention to the nuances of the MIUI shell, which may differ from pure Android. Understanding these principles will help you to maximize the potential of your smartphone.

It’s worth noting that not all apps support window mode, which is a limitation of the Android operating system, not a defect of the device. However, for most popular services such as YouTube, Telegram, browsers and maps, this functionality works flawlessly. Below are step-by-step instructions that will help you customize the gadget to your needs.

Preparing the device for multitasking

Before you start setting up a split screen, you need to make sure that your device is ready to work with multiple active windows. This is primarily about the amount of RAM. Redmi 9C has 2, 3 or 4 GB of RAM depending on the modification, and running two "heavy" applications at the same time can slow down the system.

The second important aspect is the version of the operating system and the MIUI shell. Developers regularly make changes to the interface algorithms, so the current software guarantees all the necessary functions. Check for updates in the appropriate settings section. Also make sure that the system does not activate power saving modes that can force the background applications to close.

It's important to get the navigation right for a split screen, and many users are used to having three buttons at the bottom of the display, but it's much more convenient to use gesture control to work with windows, it frees up the bottom of the screen and gives you more space for content, and you can switch to gestures through the settings menu, which makes interaction with the interface more intuitive.

Using the recent app menu to split

The most common and versatile way to activate Split Screen on Xiaomi is to use a list of running apps. This method works consistently on all versions of the firmware and does not require additional settings. To start, open two applications that you plan to use simultaneously. For example, launch a browser and messenger.

After you start the apps, go to the recent task menu. If you use the navigation button, click the square button. If you have gestures enabled, swipe from the bottom up and hold your finger in the center of the screen. In the list that opens, find the card of the first application. Depending on the version of MIUI, you either need to click on the app icon at the top of the card, or make a long tap on the card itself, or swipe the card to the right or up to appear the action menu.

In the context menu that appears, select "Separate Screen" (an icon with two rectangles). The screen will automatically split in half: the top will remain the selected application, and the bottom will open a list of other running programs. Select the second application from the list. Now you can adjust the size of the windows by dragging the separation line.

• 📱 Click on the app icon in the recent tasks card to call the menu.
• ✋ Select the option "Separate screen" in the action list that appears.
• 🔄 Confirm the launch of the second application at the bottom of the display.
• ↔️ Move the border between windows to change their size.

💡

If the menu doesn’t appear with a long press, try swiping the app card to the right (on some versions of MIUI) or up to open additional options.

Setting up and using the sidebar (Sidebar)

For those who often use split-screen mode, the sidebar is a great solution. This tool allows you to run a second application over the current one as a floating window or immediately in split mode without interrupting current activity. On Redmi 9C, this feature can be called "floating windows" or "sidebar" depending on the regional version of the firmware.

To activate the panel, go to Settings, then select Additional and find Floating Windows or Sidebar. Turn on the Sidebar switch. Then a semitransparent bar will appear at the edge of the screen (left or right, depending on the settings).

You can set up a list of apps that will be displayed in the panel. Add messengers, calculators, notes or voice recorders. When you click on the app in the sidebar, it will open in a floating window. If you drag this window to the edge of the screen, it can automatically turn into split screen mode. This allows you to instantly switch between tasks.

⚠️ Warning: The sidebar can override controls in games or videos. If you notice that the panel is intrusive, temporarily turn it off in the settings or remove the swipe.

Work with windows: resizing and fixing

Once you've split the screen in two, you can flexibly control the space, the boundary between two active windows is not static, you can move it up or down, changing the proportions of the area you occupy, and this is especially useful when you need to see a lot of text in one window (like an article) and in the other just an input bar or a control button.

An important function is to anchor applications. In split-screen mode, one of the windows can be secured so that it does not close when you clear memory or start heavy games. To do this, click on three dots or a special icon in the center of the separation line (if available in your version of MIUI) and select "Secure" to prevent an important application from accidentally closing, such as a navigator or video call.

Also worth mentioning is the floating window button, which is often next to the Split Screen Closing button, which turns the bottom window into a small floating window that can be moved around the screen, creating a hybrid mode that combines the benefits of split screen and Picture-in-Picture.

To exit split-screen mode, you just drag the dividing line up or down to the end, completely closing one of the windows. Or you can press the "Close" button at the top of one of the windows. The system automatically rolls the remaining application onto the entire screen.

Application compatibility and technical limitations

Not all programs support split mode, because app developers must explicitly specify support for scaling and multiwindow in the code. Popular services like YouTube, Google Chrome, Telegram, WhatsApp are usually fully adapted, but some games or specialized applications may be forced to close or unfold to the full screen when you try to split.

If the application does not support Split Screen, the system may issue a notification that the application may not work correctly, or simply prevent you from selecting it in the second window. In some cases, you can force support through the developer menu, but this can lead to unstable program operation, crashes or improper display of the interface.

Solving common problems and failures

Sometimes users are faced with a situation where the split screen function stops working or does not work correctly. The screen may flash, applications may not open in the second window, or the system may spontaneously close one of the windows, most often due to overflow of RAM, in which case you need to close unnecessary tabs in the browser and background applications.

Another common problem is application version conflict: Make sure that the programs used are updated to the latest version via Google Play or GetApps. Older versions may not have the necessary libraries to work with newer versions of Android.

If the problem persists, check the special features settings. Some features, such as zoom in or color inversion, may conflict with split-screen rendering. Turn them off temporarily for check. In extreme cases, you can reset the interface settings, but this will return all system preferences to factory ones.

⚠️ Note: Do not attempt to break the screen into three or more parts using third-party software. MIUI They do not support this natively, which will lead to critical interface errors.

💡

The stability of Split Screen depends on the amount of free RAM and the optimization of the applications themselves by developers.
