Multitasking on modern smartphones has long ceased to be the province of flagships and has become a basic function of the operating system. The ability to simultaneously view the news feed and respond to messages or, what is more important for many users, launch two games or a game and a walkthrough guide, significantly saves time. The split-screen feature, often called Split Screen, allows you to make efficient use of display space, especially on devices with higher resolutions.
However, the implementation of this mode may vary depending on the manufacturer of your device. While “pure” Android offers a standard algorithm of actions, shells from Samsung, Xiaomi or Huawei can have their own gestures and menus for activation. Understanding these differences is critical for those who want to quickly switch between tasks without unnecessary taps on the screen.
In this article we will analyze in detail all the ways to activate the dual-window mode, the features of its work with heavy applications and games, and also consider the pitfalls that you may encounter. You will learn how to properly scale windows, save pairs of applications for quick launch, and what to do if the desired app refuses to work in this mode.
Basic principles of split screen operation
Technologically, split screen mode is the simultaneous launch of two active processes Activity in the visible area of the display. The system shares CPU and RAM resources between two applications, which can result in poor performance in resource-intensive tasks. This is why game applications are not always displayed correctly in this mode, since many developers block this feature to prevent rendering errors.
When the function is activated, the screen is divided into two independent zones. The top (or left, depending on the orientation of the device) part usually remains active for interaction, while the second part waits for the second application to be selected. System restrictions Android allow developers to prohibit the launch of their software in multi-window mode if the application interface is not adapted to the reduced resolution.
⚠️ Attention: Running two heavy 3D games at the same time can lead to strong heating of the smartphone body and a sharp drop in frame rate. Use this mode with caution on devices with weak cooling systems.
It is also worth considering that some functions may not work correctly in split-screen mode. For example, full-screen videos may automatically minimize, and games that require constant input focus may pause if you actively interact with a second window. This is due to how window manager handles input focus in the operating system.
Before activating dual window mode, close background applications to free up RAM. This will help avoid game crashes due to lack of resources.
Activation through the recent applications menu
The most universal and common way to launch two windows works on almost all versions Android starting with 7.0 Nougat. This method does not require special developer settings to be enabled and is available out of the box. The algorithm of actions is intuitive, but requires some skill when using it for the first time.
First, open the application that you want to place in the first half of the screen. This could be a browser, instant messenger, or game that supports multitasking. Then minimize it and go to the recent applications menu. Depending on the type of navigation, this is done by swiping up from the bottom and holding or pressing the square button at the bottom of the screen.
In the list of running apps that opens, find the card of the desired application. On most devices, you need to press and hold the app icon at the top of the card. In some shells, for example in older versions MIUI, you need to click on three dots or a special icon above the application name. After this, a context menu will appear with a choice of display mode.
- 📱 Select the “Split screen” item or the icon with two rectangles.
- 🔍 The system will prompt you to select a second application from the list of recently used or the full menu.
- ⚖️ Use the dividing bar to change the proportions between windows.
- ❌ To exit the mode, drag the dividing bar to the very edge of the screen.
After selecting the second app, the screen will be divided into two parts. You can resize windows by dragging the black or gray separator bar. This is convenient when you need to give more space to the game, leaving only a narrow strip for chat or browser. However, remember that the minimum window size is limited by the system requirements applications.
Using gestures and sidebar
Smartphone manufacturers often add their own improvements to make multitasking easier. For example, devices Samsung equipped with a function Edge Panelthat allows you to display a panel of your favorite applications on the side of the screen. This significantly speeds up the process of launching a second window without having to minimize the current app.
To use this method, you first need to activate the sidebar in the display settings. After turning it on, you can call it by swiping from the edge of the screen. The panel displays pinned applications. To launch in split-screen mode, simply drag the icon of the desired app from the panel to a free area of the display. The system will automatically adjust the windows to the available space.
Similar solutions exist from other vendors. Xiaomi offers the “Floating Windows” feature, which allows you to run applications in the form of small moving windows on top of the main app. This is not exactly a classic split screen, but for many use cases, such as watching a stream while playing a game, this option is even more convenient. Activation is carried out through the control center or the recent tasks menu.
⚠️ Attention: The interface and names of menu items may vary depending on the firmware version and smartphone model. If you do not find the described items, check the "Accessibility" section in the settings.
Some users prefer to use navigation gestures without buttons. In this case, the recent applications menu is called up by swiping up from the bottom edge of the screen with a short pause at the central point. Holding your finger on an app card in this menu also brings up a split-screen option. Mastering these gestures allows you to manage multitasking literally with one touch.
The secret of quickly changing window locations
Tap and hold the central dividing bar, then drag it to the opposite side of the screen or use a special button for changing locations, if available in your version of Android.
Specifics of operation with games and multimedia
Running games in split-screen mode has its own technical features. Many modern games use full-screen mode and take over all the resources of the graphics accelerator. When you try to launch such a game in the second window, it may simply collapse into an icon or display an error. This is due to the fact that the developers explicitly indicate in the application manifest that window resizing is prohibited.
However, there is a category of games that work perfectly in multi-window mode. These include turn-based strategies, card games, text quests and simple arcade games. For such entertainment, the two-window mode is ideal: you can play through the game and simultaneously communicate on Telegram or watch a video on YouTube. It is important to check the support of the function before a long gaming session.
If the game does not support split screen using standard means, you can try the forced method through the developer settings, which will be discussed below. However, you should be prepared for the fact that the game interface may move, and the control buttons will become invisible or unclickable. In such cases, it is better to return to the standard full-screen mode.
| Application type | Split Screen support | Operation features |
|---|---|---|
| Messengers | Full | Stable operation, notifications arrive in real time. |
| Browsers | Full | Can redraw the page when the window size is changed. |
| Heavy 3D games | Partial/Absent | Often minimized or require forced mode. |
| Video players | Full | Automatic inclusion of picture-in-picture is possible. |
| Social networks | Full | News feeds adapt to the width of the window. |
It is also worth noting the behavior of video content. Many video players automatically activate the mode when switching to split-screen mode Picture-in-Picture (picture-in-picture), allowing the video to float on top of other windows. This is a separate feature that is often confused by users with regular split screen, but is a more flexible tool for consuming media content.
Not all games support multitasking at the code level. If the application minimizes when you try to split the screen, then the developer has blocked this feature to preserve performance.
Forced activation through developer settings
For advanced users who want to run applications in two windows that do not officially support this feature, there is a hidden setting in the developer menu. This method causes the system to ignore the restrictions specified by the application developer and force the interface to scale.
You must first enable Developer Mode. To do this, go to the section Settings → About phone and find the item Build number. Click on it quickly 7 times in a row until a message appears indicating that you have become a developer. After this, a new section will appear in the main settings menu For developers.
Inside this section you need to scroll down the list to the item usually called "Applications in multi-window mode"** or Force activities to be resizable. Activate this switch. Once enabled, you may need to restart your device for the changes to take effect. Now the system will try to launch any application in split mode.
Activation path: Settings → For developers → Applications in multi-window mode (ON)Using this function carries certain risks. Forcing scaling may cause in-game controls to become too small or overlap each other. In some cases, the application may simply crash upon launch. Use this method only if you understand the consequences and are prepared for unstable operation of the software.
☑️ Check before enabling developer mode
Solving common problems and errors
Despite the well-developed function, users often encounter problems when using two windows. One of the most common complaints is the inability to change the size of windows or the “sticking” of the dividing strip. This is usually solved by simply rebooting the device or clearing the launcher cache.
Another problem is related to automatic exit from the mode. Some games require full focus when starting an audio track or video insert and automatically expand to full screen, closing the second application. This behavior is inherent in the logic of the operation of multimedia frameworks Android and it is difficult to bypass it without third-party utilities.
⚠️ Attention: If, after enabling the developer mode, the smartphone begins to work unstable, return the “Applications in multi-window mode” setting to its original position. Do not leave this mode enabled unless necessary.
Users also notice increased battery consumption. This is quite natural, since the screen works constantly, and the processor processes two active data streams. To save energy, it is recommended to lower the display brightness and disable background syncing in unnecessary applications during a multitasking session.
If you cannot find the setting you need or the feature is missing, your device manufacturer may have decided to abandon it in favor of other solutions, such as floating windows only. In this case, you should contact the official documentation of the model or the brand support forum.
Frequently asked questions (FAQ)
Why is the split-screen button inactive (gray) for some applications?
This means that the application developer has prohibited working in split-screen mode. This often applies to banking applications for security reasons or heavy games that cannot work correctly at a reduced resolution.
Is it possible to run three applications simultaneously in a split screen?
Standard Android mode only supports two active windows at a time. However, some manufacturers (for example, Samsung in Pop-up View mode) allow you to launch several floating windows on top of the two main ones, creating the illusion of working with three or more applications.
How to save a couple of applications for quick launch in the future?
In the recent applications menu, when split-screen mode is running, an icon for saving the pair often appears (usually an icon with two stars or the inscription “Save”). By clicking on it, you can launch this combination with one touch from the recent tasks menu or from the main screen.
Does dual-window mode affect FPS in games?
Yes, it does. Since GPU and RAM resources are shared between two applications, the game's frame rate may be reduced. On weak devices, this can lead to noticeable slowdowns.
Is it possible to use split screen on Android tablets?
Yes, on tablets this function is implemented even better, since the large screen space allows you to comfortably place two full windows without greatly reducing the interface scale. The activation principle is similar to smartphones.
