How to make 2 applications on one screen Android: Complete Guide

The modern pace of life dictates its own rules, and a smartphone has long ceased to be just a device for making calls. Today we are often faced with the need to perform several tasks at the same time: chatting in instant messenger, simultaneously watching videos on YouTube or checking documents in the browser. Fortunately, the operating system provides a powerful tool to solve this problem - split screen mode, also known as Split Screen. This feature allows you to literally cut the display in half, placing two different active applications at the top and bottom. Android provides a powerful tool to solve this problem - split screen mode, also known as split screen (Split Screen). This feature allows you to literally cut the display in half, placing two different active applications at the top and bottom.

Using multitasking on a mobile device significantly increases productivity, eliminating the constant need to minimize and expand apps. However, many users still do not know how to activate this feature, considering it a privilege of tablets or flagship models. In fact, you can enable two applications on one screen on most devices running Android 7.0 Nougat and higher, be it a budget smartphone or a top-end gadget. In this article we will analyze in detail all the activation methods, settings and possible nuances of working in multi-window mode.

Before moving on to the step-by-step guide, it is worth noting that the interface may differ slightly depending on the manufacturer. Shells like Samsung, Xiaomi or Oppo have their own unique gestures and menus. However, the basic principles of the system remain the same for the entire ecosystem. Understanding these principles will allow you to easily adapt to any device and get the most out of your smartphone. One UI from Samsung, MIUI from Xiaomi or ColorOS from Oppo have their own unique gestures and menus. However, the basic principles of the system remain the same for the entire ecosystem. Understanding these principles will allow you to easily adapt to any device and get the most out of your smartphone.

Checking compatibility and preparing the system

The first step before activating multitasking is to make sure that your device technically supports this feature. Starting from version Android 7.0, split-screen mode is built into the system core, but some manufacturers may have disabled it in their firmware to save resources or for other reasons. It is also important to consider the amount of RAM: for comfortable operation of two “heavy” applications, for example, a navigator and a video player, it is advisable to have at least 4 GB RAM.

If you have an old phone model or custom firmware, the function may be hidden in the developer menu. To check this, you need to go to Settings → About phone and quickly click on the build number several times until a notification appears that you have become a developer. After this, a new item For developerswill appear in the main settings, where you can find the switch Forcing multi-window mode. Activating this option allows you to run in split screen even those applications that do not officially support this function.

⚠️ Attention: Forcing multi-window mode for incompatible applications may lead to incorrect display of the interface, app crashes or excessive battery consumption. Use this option only if absolutely necessary.

You should also make sure that both applications you plan to use are not system utilities with restrictions. Some apps, such as a pure calculator or voice recorder, may not scale properly. In this case, the system will automatically prompt you to select another application or display a notification that it is impossible to split the screen. Checking compatibility will save you time and nerves in the process of setting up your working environment.

Activation through the recent applications menu

The most common and universal way to launch two applications at the same time is using the recent tasks menu. This method works on the vast majority of smartphones with navigation buttons or gesture controls. First, open the first app you want to pin to the top or bottom of your screen. Then minimize it and open the second application so that it also remains in the history of running apps.

Next, call up the recent applications menu. If you use navigation buttons, this is done by pressing the square button or the three-bar button. When using gesture controls, you need to swipe up from the bottom edge of the screen and hold your finger in the center of the display for a split second. In the list that opens, find the card of the first application. At the top of this card, above the app name, there is usually an application icon or a special menu button.

• 📱 Click on the application icon at the top of the recent tasks card.
• 📂 In the drop-down list, select Split screen (or Split Screen).
• 🖼️ The screen will split in half: the first application will occupy the top part, and a selection menu for the second application will open at the bottom.
• ⚙️ Tap the icon of the second application from the list of recent ones or select it from the all apps menu.

After completing these steps, both applications will be active and displayed on the display at the same time. The border between them is movable: you can drag the dividing bar up or down, resizing the windows to suit your needs. For example, if you are reading an article and replying to messages, you can allocate more space to the browser by leaving a narrow strip at the bottom for the messenger. This provides flexibility that is not available with normal switching between tasks.

Use of gestures and sidebar

Smartphone manufacturers are constantly improving the user experience, introducing more intuitive ways to manage multitasking. Owners of devices from Samsung, Xiaomi i Honor can use the sidebar function or special gestures that allow you to launch a second application with literally one touch, without going to the recent tasks menu. This is especially convenient when your hands are busy or you need to quickly respond to a notification.

On devices Samsung with a shell One UI there is an Edge Panel function. By activating it in the display settings, you get access to a hidden curtain on the edge of the screen. In this curtain, you can customize the “Recent Applications” panel or add specific app shortcuts. To split the screen, simply drag the application icon from this panel to a free area of ​​the display. The system will automatically adjust the windows, placing the active application at the top and the one being dragged at the bottom.

Settings → Display → Edge panels → Panels → Select "Applications" or "Recent"

In smartphones Xiaomi i Poco with a shell MIUI or HyperOS a similar mechanism is implemented through the “Side Panel”. It is called by swiping from the edge of the screen to the area where the application is open. The menu that appears displays your favorite apps. Clicking the icon in this menu will instantly activate split-screen mode. This allows you to create ready-made pairings of applications that you use together most often, for example, “Maps + Player” or “Bank + Calculator”.

Setting window sizes and managing the divider

After you have successfully launched split screen, you are faced with the task of optimal distribution of space. By default, the system splits the screen exactly in half (50/50), but this ratio is rarely ideal for all use cases. The central separator strip, usually gray or black, serves as the main tool for controlling the proportions of the windows. Understanding how to interact with it is critical to comfortable work.

To change the size of windows, move your finger over the dividing line and hold it until vibration or visual feedback appears. Without releasing your finger, move the line up or down. As you move the line up, the top app will take up more space and the bottom app will shrink. This is useful when you need to see details on a map or read small text in a browser, leaving the second application minimized to a narrow preview pane.

Usage scenario	Recommended ratio	Advantage
Watching video + Chat	70% (Video) / 30% (Chat)	Maximum picture quality, easy to read messages
Typing + Search	50% / 50%	Equal access to the keyboard and source of information
Navigation + Music	80% (Map) / 20% (Player)	Good visibility of the road, track control without distraction
Two messengers	50% / 50%	Convenient to copy text and media files between chats

It is worth remembering the minimum window size restrictions. The system will not allow the application to be compressed to the point where its interface becomes unreadable or non-functional. If you try to make the window too small, the separator will "stick" to the edge and the application may automatically minimize or enter floating window mode, if such a feature is supported. On some models, double-clicking the splitter instantly aligns windows 50/50, which is a quick way to reset view settings.

Floating window mode as an alternative

Sometimes splitting the screen exactly in half or in fixed proportions is not a flexible enough solution. In such cases, the floating window (Pop-up view) mode comes to the rescue. Unlike a split screen, where applications occupy the entire width of the screen, a floating window can be located anywhere on the display, have an arbitrary size and overlap the main application. This is ideal for short-term tasks, such as answering a call, viewing a notification, or using a calculator.

You can activate the floating window from the same recent applications menu. Instead of selecting Split Screen, look for the Open in pop-up window option or tap the window icon at the top of the app card. On devices Samsung this is often done by long pressing the application icon in the recent tasks menu. Once opened, the window can be moved behind the top panel, resized by pulling the corners, and minimized to a small icon on the edge of the screen when not needed.

The secret of collapsing a floating window

If you click on the bottom of a floating window (control panel), it will collapse into a small round icon that can be dragged to any corner of the screen. Pressing it again will expand the window back to its previous size.

The main advantage of a floating window is the ability to use more than two applications at the same time. You can have one app in full screen mode, a second in split screen mode, and a third as a floating window on top of them. However, it is worth considering the load on the processor: three active applications can cause stuttering on mid-range and budget devices. Use this mode with caution, closing unnecessary background processes.

Solving common problems and limitations

Despite the convenience, users often encounter a situation where the split screen button is inactive or the application refuses to launch in the second window. The most common reason is the lack of support for the mode on the part of the developer of a particular application. Social networks, banking applications and some games often block the ability to work in split screen for security reasons or interface features.

Another problem may be the automatic exit from multitasking mode when you rotate the device. Many applications are strictly tied to portrait orientation, and when you try to rotate the smartphone into landscape mode, the system may force you to close one of the windows or expand the active application to full screen. To avoid this, lock the screen orientation through the notification shade before working in split-screen mode.

⚠️ Attention: When using navigation applications in split-screen mode, the sound of voice prompts may become quieter or disappear altogether if the second application is playing media content. Check your multimedia sound settings before you start your trip.

If an application crashes immediately after splitting the screen, try clearing its cache. Go to Settings → Applications, select the problematic app, go to the Memory section and click “Clear cache”. This often resolves interface rendering conflicts in a smaller window. In extreme cases, when standard methods do not work, you can use third-party launchers or utilities to force multitasking, but this requires superuser rights (Root) and carries risks for system stability.

Frequently asked questions (FAQ)

Is it possible to run two identical applications on the same screen?

Yes, this is possible, but only if the function is installed on your smartphone "App Cloning" or "Dual Apps". Many manufacturers (Xiaomi, Samsung, Huawei) allow you to create a copy of a messenger, for example, a second WhatsApp. In split-screen mode, you can run the main account in one window, and the cloned one in another, gaining access to two different profiles at the same time.

Why is there no “Split Screen” button on my phone?

The absence of a button can be caused by several reasons: an outdated version of Android (below 7.0), the manufacturer has disabled the function in the settings, or the application does not support this mode. Also check to see if One Handed Mode or Easy Mode is enabled, which may block multitasking. Try updating the system to the latest available version.

Does dual application mode affect battery consumption?

Of course, running two active applications at the same time consumes more processor resources and RAM, which leads to faster battery drain. The screen also operates at increased brightness and load when both applications dynamically update content. For long-term work in split-screen mode, it is recommended to have a power bank or charger on hand.

How to exit split-screen mode?

To exit the mode, simply drag the dividing bar to the very top or to the very bottom of the screen. This will expand the selected app to fill the entire display and close or minimize the second app to the background. You can also press the Home button, which will minimize both applications, or the Back button, which will close the currently active window.
