Modern smartphones have computing power that was considered excessive even for desktop computers ten years ago. However, many users still use their devices Android in “one application” mode, missing out on the opportunity to significantly increase personal efficiency. Multitasking on the Google platform is not just switching between tabs, but full-fledged work with several windows at the same time.
Establishing a habit using split screen floating windows changes the approach to interacting with the gadget. You can watch a training video while taking notes, or chat in messenger while navigating the maps. The operating system provides powerful tools for this, but they are often hidden deep in the settings or require specific actions to activate.
In this guide, we will look at all the available ways to organize your workspace. We will look at standard functions, hidden features for advanced users and the nuances of working with windowed mode on different firmware versions. Get ready to turn your phone into a pocket-sized task center.
Basic principles of split screen on Android
Let's start with the foundation. Most modern smartphones based Android 7.0 Nougat and higher support the native split-screen function. This mode allows you to occupy the top half of the display with one application, and the bottom half with another. To activate the classic split screen, you do not need root access or complex manipulations; you just need to know the correct sequence of actions.
There are several ways to launch split view. The most common method works through the recent applications menu. You need to open the first application, then go to the overview of running apps (swipe from bottom to top with a delay or the “square” button). Find the icon of the desired application and click on the logo above the preview window.
In the context menu that opens, select “Split screen”. The system will automatically move the active window up, and at the bottom it will prompt you to select a second application from the list of recently used ones. Once selected, both apps will occupy approximately 50% of the usable display area, which is the optimal balance for reading and entering text.
- 📱 Tap and hold the application icon in the recent tasks menu for quick access.
- 🔄 Swap applications by dragging the dividing line to the center of the screen.
- 🔍 Use the search in the recent tasks menu to find the desired app for the second window.
- ⚙️ Adjust the window proportions by moving the black or gray separator bar up or down.
⚠️ Attention: Not all applications are optimized for working in split-screen mode. Some apps, especially older or highly specialized ones, may force close or appear as a narrow bar. In such cases, the system usually displays a notification that the application does not support this function.
Floating windows and Picture-in-Picture mode
In addition to rigidly splitting the screen in half, the operating system Android offers a more flexible tool - floating windows. This feature allows you to launch an application in a small window that “floats” on top of the main content. You can move such a window across the entire screen, change its size, or temporarily minimize it to the edge of the display.
The technology is of particular interest. Picture-in-Picture (PiP). It is intended primarily for video content and navigation. After launching a video on YouTube Premium or in a browser, you can minimize the application, and the video stream will continue to play in a small window on top of the desktop or other apps. This is ideal for watching streams while chatting.
A special set of gestures is used to control floating windows. Typically, in the corner of a floating window there are control buttons: minimize, expand to full screen or close. Some manufacturers, for example Samsung and Xiaomi, add their own improvements, allowing you to create entire groups of floating windows that can be saved as use cases.
Secrets of managing floating windows
To fine-tune the size of a floating window, pinch it by the corner and drag it. If the window is sticking to the edges, try swiping from the center of the window to the side to unstick it from the edges. On some firmware, double tapping on a window expands it to full screen.
Using the sidebar and pop-up menus
Smartphone manufacturers often implement their own shells that expand the standard functionality multitasking. One of the most convenient tools is the Side Panel. It is a narrow strip hidden at the edge of the screen, which, when swiped, opens a list of favorite applications.
The main advantage of the sidebar is the ability to instantly launch an application in floating mode. You don't need to exit the current task. Just swipe from the edge of the screen, select the desired app from the list, and it will open on top of the active window. This is an ideal scenario for quickly replying to a message or checking exchange rates.
Customize the panel for yourself, adding only those applications that you use in conjunction with your main tasks. For example, a calculator, notes, instant messengers or a voice recorder. In the shell One UI from Samsung this function is called “Pop-up windows”, and in MIUI from Xiaomi it is called “Floating windows”.
☑️ Setting up the side panel
Comparison of methods multitasking
The choice of the appropriate operating mode depends on the specific task and the screen diagonal of your device. On larger smartphones and tablets, the difference between the modes is less noticeable, but on devices with screens up to 6 inches, every pixel counts. Understanding the differences will help you save time and avoid conflicts between applications.
Below is a table comparing the main windowing modes. It will help you quickly figure out which method to choose for your current situation. Pay attention to resource consumption, as the simultaneous operation of several heavy applications can affect autonomy.
| Operating mode | Occupied area | Best use | Impact on the battery |
|---|---|---|---|
| Separation screen | 50% / 50% (or 40/60) | Copying text, comparing data | Average |
| Floating window | 20-30% of the screen | Video calls, secondary tasks | High (constant activity) |
| Picture-in-Picture | Minimum (angle) | Watching video, navigation | Low |
| Full screen mode | 100% screen | Games, reading, viewing photos | Depends on the application |
It is worth noting that RAM consumption in multitasking mode increases in proportion to the number of active processes. If you keep three heavy applications open, the system may begin to forcefully close background processes to free up resources for the active window.
Hidden features and Developer Options
For users who lack standard features, there is a “For Developers” section. Hidden here are experimental features that allow you to force modes that are usually only available on tablets or foldable smartphones. Be careful when changing these settings as they may affect system stability.
One of the most useful hidden features is Force activities to be resizable (Force action resizing). This option allows you to run in split-screen mode even those applications whose developers have prohibited it. Activation requires enabling developer mode by repeatedly clicking on the build number in the “About phone” section.
adb shell settings put global force_resizable_activities 1Also in this section you can find the setting for the minimum screen width (Smallest width). By increasing this parameter, you can visually reduce interface elements, which actually allows you to fit more content on the screen and make it more comfortable to work with two windows at once. However, too large a value may make the text unreadable.
⚠️ Attention: The interface of the “For Developers” menu may differ on different versions Android and in manufacturers' shells. Some items may have different names or be missing. Before changing system settings, make sure you understand the consequences, as this may lead to incorrect display of the interface.
Forcing window resizing is a powerful tool, but it does not guarantee stable application operation. Some apps may behave unpredictably or crash when you try to compress their interface.
Optimization and problem solving
Despite the convenience, multitasking can cause a decrease in device performance. If you notice that your smartphone starts to heat up or work slower when using two windows, it’s worth optimizing. First of all, check which applications are consuming the most resources in the background.
Close unnecessary processes and free up RAM. It is also recommended to disable animations in the developer section, which will visually speed up switching between windows. If the problem persists, it is possible that one of the running applications has a memory leak or is conflicting with system processes.
In some cases, clearing the cache of the problematic application or reinstalling it helps. Remember that older versions of applications may not work correctly with new versions Android, so follow the updates in the official store.
- 🧹 Regularly clear memory by closing unused tabs in the browser.
- 📉 Disable live wallpapers and heavy widgets when actively working in split screen.
- 🔄 Update system software and applications via Google Play for better compatibility.
- 🔋 Use power saving mode if you plan to work with multiple windows for a long time.
Frequently asked questions (FAQ)
Why is there no split-screen function on my phone?
Perhaps your smartphone runs on version Android below 7.0, where this function is not implemented at the system level. Also, some manufacturers of budget devices can programmatically limit this feature to save resources. Check for system updates in the settings.
Is it possible to run three applications at the same time?
The standard interface Android allows you to divide the screen only into two parts. However, using a combination of split screen and floating window, you can visually place three applications: two in split-screen mode and one in a floating window on top of them.
Does multitasking affect the speed of battery drain?
Yes, running multiple active applications at the same time increases the load on the processor and screen, which leads to faster battery drain. This is especially noticeable when using navigation and the video player at the same time.
How to exit split-screen mode?
To exit split-screen mode, drag the dividing line completely up or down so that one of the applications takes up the entire display. Or simply minimize one of the windows, and the second will automatically maximize.
Does copying text between split windows work?
Yes, the clipboard in Android is global. You can copy text or an image in one app and paste it into another, even if they are open in split screen mode. This is one of the most useful features for productivity.
