Multitasking is one of the key factors that determine the usability of a modern smartphone. Owners of Xiaomi Redmi 9C devices often strive to use the potential of the MIUI operating system to its full potential, opening both the messenger and the browser or video hosting and notes. However, the standard interface is not always obvious to new users, which raises many questions about how to activate the Split Screen feature. In this article, we will discuss in detail all ways to activate the separation of the display.
Split Screen, also known as Split Screen, allows you to run two apps in separate windows on the same display at the same time, which makes your Redmi 9C a powerful tool for work and entertainment. You can text to Telegram or WhatsApp without interrupting a YouTube video, or copy text from a single article, pasting it into a document. Although MIUI is based on Android, the implementation of this process has its own unique features that you need to consider.
There are several ways to activate this feature: through the system menu of recent applications, through the control panel or special gestures. Each of these methods has its advantages depending on the use case. In this article, we will discuss each method Step-by-step, paying attention to the nuances of customization and possible limitations that you may encounter when using Multi-window mode on a budget device.
System preparation and application compatibility check
Before you start directly activating split screen, you need to make sure your software is ready to multitask. On Xiaomi devices, the split screen feature is built into the default MIUI shell and does not require installing third-party software. However, for the system to work properly, it is important that the operating system is updated to the current version available for your model.
It's important to understand that not all applications support Split Screen. It's up to developers to decide whether to allow their interface to be scaled, and most often, problems arise with video players or games that require full-screen mode to properly display graphics. If the application doesn't support splitting, the system will simply open it to the full screen, ignoring the split command.
To check the availability of the function and the basic interface setting, follow the following steps:
- 📱 Make sure you have your Redmi. 9C version MIUI at least 11, as older versions may have limitations.
- 🔄 Restart the device to clear the RAM RAM before launching heavy applications.
- 📂 Check for updates in the Settings section → The phone. → Version. MIUI.
⚠️ Note: Some system applications, such as Calendar or Recorder, may not display correctly in a reduced window, cutting off part of the interface.
Classic method through the menu of recent applications
The most common and reliable way to start splitting the screen on Xiaomi Redmi 9C is to use the menu of running tasks. This method works consistently on all versions of the firmware and does not require the inclusion of additional options in the developer menu. The algorithm of actions is simple, but requires a certain sequence of taps to get used to.
First, you need to open the first app you plan to use, which can be a browser, a social network, or any other service. Once the app is launched without closing it completely, go to the menu of recent apps. On Redmi 9C, this is done by swiping from the bottom up with a delay or press of the appropriate navigation button, depending on the type of navigation you choose.
Follow the instructions:
- 🖱️ In the open window menu, find the card of the desired application and click on the icon at the top of the card (or swipe by card if the corresponding gesture is enabled).
- ✂️ In the context menu that appears, select “Share split” (an icon with two rectangles).
- 📱 The screen will split in half: the top part will remain the first application, and the bottom will open the choice of the second.
Now, at the bottom of the display, select the second app from the list of recently used apps, or find it in the general list. Once selected, both apps will be active at the same time. You can change their size by dragging the dividing line, or close one of the windows by clicking on the cross.
☑️ The algorithm for enabling Split Screen
Use of control panel and quick settings
An alternative method that may seem more convenient for some users involves using the Quick Settings Panel, which allows you to activate split-screen mode without going to the menu of recent apps, which saves time. However, it requires you to pre-configure the control panel, since the split-screen button can be hidden by default.
To add the required button, lower the notification curtain down to the end and click on the edit button (usually a three-strip icon or a pencil in the upper right corner). In the editor that opens, find the "Share Partition" or "Split screen" element and drag it to the active Quick Settings area. Once you save the changes, the button will be available for quick call.
The activation process is as follows:
- 🔽 Open the swipe control panel from top to bottom.
- ⚙️ Click on the added split screen icon.
- 📲 The system will prompt you to select the first application from the list of running or all installed programs.
Once you select the first application, the screen will automatically split, leaving you to select the second application from the list, a method that is particularly handy when you are on a desktop and want to quickly run a couple of programs without opening them first.

If you often use the same pair of apps, try creating shortcuts for them on your desktop.Some launchers let you run apps right away in Split Screen mode through a long-term icon tap.
Customization of gestures and additional parameters
For advanced users, Xiaomi provides the ability to fine-tune the system's behavior when working with windows. In some versions of MIUI, the function of starting the split screen with a special gesture is available, which greatly speeds up the process.
To activate gesture control, go to Settings → Additional settings → Screen split. Here you will find the "Start split screen by holding your finger" switch. By activating this option, you can swipe your finger from the edge of the screen (usually from the corner) to call the split menu. This requires some skill, but it speeds up the work significantly.
It is also worth paying attention to the following parameters:
- 🎚️ Window size: You can change the proportions of windows by dragging the central strip.
- 🔄swap: the button to exchange seats allows you to quickly change the top and bottom applications.
- ❌ Closing: Swiping on the central strip to the side allows you to quickly close one of the windows.
It is important to note that using gestures can conflict with system navigation if you have gesture control instead of buttons enabled, in which case the system may require more complex movement, such as swiping your finger from an angle with a slight delay.

Comparison of methods and compatibility of functions
The choice of the method of activating split screen depends on your personal preferences and the specific situation, each method has its own technical features and affects the performance of the device in different ways.
| Activation method | Speed of access | Compatibility | Convenience |
|---|---|---|---|
| Task menu | Medium | Tall. | High. |
| Control panel | Tall. | Medium | Average. |
| Gestures | Very high. | Low (requires settings) | High. |
| Voice commands | Low. | Depends on the assistant. | Low. |
As you can see from the table, the classic method through the task menu remains the most versatile and stable, ensuring that the system correctly identifies running processes and allocates the processor resources correctly.
Keep in mind that running two active apps simultaneously increases the load on RAM. On the Redmi 9C, which is equipped with 3 or 4 GB of RAM, this can lead to more aggressive closure of background processes. If you notice one of the applications in the split screen constantly reboots, try closing other background programs.
Typical problems and ways to solve them
Despite the stability of MIUI, users may encounter a number of common problems when using Split Screen, most often due to incompatibility of specific versions of applications or lack of system resources, and understanding the causes of errors can help to quickly eliminate them.
One common problem is that the dividing line is stuck or the windows cannot be resized, often by simply restarting the interface or the device itself, and there may be a problem when the second application does not open or closes immediately after starting in split mode.
The main causes of failures:
- ⚠️ Lack of free RAM to accommodate two heavy applications.
- 🚫 Blocking a function by the developer of a particular application (often found in banking applications).
- 🐛 Error in the current version of the firmware MIUI.
⚠️ Warning: If the device starts to heat up or discharge rapidly after splitting the screen, close one of the applications immediately.Simultaneous operation of two resource-intensive processes can cause Redmi to overheat. 9C.
In some cases, cleaning the problem app cache through the settings menu helps. Go to Settings → Apps → All apps, find the desired program, select Memory and click Clear Cache. This will not delete your personal data, but can correct display errors.
💡
Split Screen’s stability is directly dependent on the amount of free RAM available. Close the background processes for better performance before running two heavy applications.
