Xiaomi Why Floating Windows Don’t Work: Full Version

Owners of Xiaomi, Redmi and POCO smartphones often face a situation where the usual multitasking functionality ceases to respond correctly to user commands. Instead of a convenient small window on top of the main application, the screen remains static or the application simply unfolds on the entire display. This is annoying, especially if you are used to texting in the messenger while watching videos or working with documents.

The problem can lie in the banal incompatibility of a particular application, and in the deep settings of the shell MIUI or HyperOS. Android security sometimes blocks access to the overlay of windows for the sake of saving battery power or protecting data. Understanding the mechanisms of the background processes will help you quickly return the usability of the gadget.

In this article, we will discuss in detail all possible causes of failures, disabled developer functions and hidden system limitations. You will learn how to properly configure application permissions and use special gestures to activate Picture-in-Picture mode. Don’t rush to bring the device to the service, most likely, the matter is solved in a couple of minutes in the settings.

Application compatibility checks and system limitations

The first thing to realize is that not every app supports floating windows. Android allows developers to decide for themselves whether their software will work in Picture-in-Picture format. For example, popular video services like YouTube or Netflix have their own limitations that can block standard system behavior.

Many users mistakenly rely on the floating windows feature in recent apps menus, which is actually a split-screen mode rather than a full-fledged floating window. A real floating window should move freely across the display and have a minimalist control interface. If the application is not optimized for this, the system will force it to deploy.

On older versions of Android (below 8.0), the functionality may have been unstable or require super-user rights. In modern shells from Xiaomi, priority is given to applications from Google Play, while software installed from unknown sources is given to applications from unknown sources (APK-files, can be blocked by the security system.

• 📱 Check if the app has official PiP (Picture-in-Picture) support).
• 🔄 Make sure the app version is updated to the latest available in the store.
• ⚙️ Some Chinese firmware versions may have reduced functionality for global applications.

Set up special features and permits

Often the reason is that the app simply doesn't have permission to display on top of other windows. In the Xiaomi ecosystem, this is regulated through a special feature menu. Without that permission, the system will ignore commands to fold the application into floating mode.

To fix this, you need to go to the security settings, find the privacy or special features section, which requires you to find your application (for example, a video player or messenger) and activate a switch that allows you to display on top of other programs.

Note that after major MIUI updates, these settings can be reset to factory values, and this is done for security reasons so that malicious software cannot cover the interface of banking applications invisibly, so if the feature stops working after the update, you need to check again.

⚠️ Note: Do not grant permission to display over other windows to questionable applications from unknown sources, this could lead to phishing or data theft.

Another important aspect is the operation of background processes: If the system aggressively unloads the application from memory, the floating window will simply disappear. In the battery settings for a particular application, select No Limits mode to ensure stable operation.

Activation of Developer Functions for Advanced Management

For advanced users who want full control of multitasking, there are hidden developer settings, and this is where you can force Freeform Windows to activate, which allows you to turn any application into a floating one.

To enter this menu, you need to click on the build number in the About Phone section several times until you have a message that you have become a developer, and then a new menu item will appear in the advanced settings. Be careful: changing the settings here affects the operation of the entire system.

We're interested in Force Resizable Activities, which allows you to float even applications that don't officially support this option, but the interface may not be displayed correctly.

💡

Use the free form feature with caution: some applications may freeze or incorrectly maintain their state when closed.

You can also find the setting of the minimum width of the window (Smallest width), which changes the setting affect how small the windows can be, but for basic operation of floating windows this is not a requirement.

Use of gestures and third-party launchers

Xiaomi shells offer various ways to activate floating windows through gestures, most often swipe three fingers up or long pressing the menu button in running applications. If standard gestures do not work, they may be disabled in the settings of additional features.

Users who have installed third-party launchers (Nova Launcher, Lawnchair) may face a window management conflict. The native MIUI launcher is best integrated with system multitasking functions. For maximum stability, a standard interface is recommended.

There are also special assistant apps like Floating Apps or X-plore that create their own floating window layer. They bypass system constraints by running their versions of browsers, calculators and file managers on top of any screen.

When using third-party solutions, it is important to understand that they consume more battery resources, as they create an additional layer of rendering, which can lead to faster heating of the case with active multitasking.

Problems with memory and MIUI optimization

Aggressive memory optimization is one of the main reasons why floating windows die right after opening, and Xiaomi’s system seeks to free up RAM for active applications by ruthlessly closing the background processes that a floating window includes.

To combat this, you need to manually fix an important application in memory, open the menu of running applications, find the right window, press it and press the lock icon, which will prevent the system from unloading the process from RAM.

Also, check the amount of free memory. If more than 90% of internal storage is filled, the system starts to run slower, and multitasking functions can be turned off automatically to maintain the performance of the main interface.

⚠️ Attention: Memory cleanup through the built-in accelerator ("Junk") often closes all background applications, including floating windows.

On devices with less than 4GB of RAM, several heavy applications may not be physically possible to run in floating mode without lags, in which case the system itself limits functionality.

Resetting and system update

If the software settings don't work, you may have accumulated software debris or system services have failed, try clearing the cache of the system application Security or resetting the special features settings.

Check for updates to your version of MIUI or HyperOS. Engineers regularly release patches that fix multitasking bugs. Sometimes the problem is massive and solved only by the release of a new version of the firmware.

💡

Consistent verification: application compatibility -> permission -> developer settings -> memory fixing.

In extreme cases, if nothing helps, you can reset all settings to factory.Be sure to back up important data before doing so, as this step will remove all user configurations.
