The situation of a running app suddenly shutting down and returning you to the desktop is one of the most annoying issues in the Android ecosystem.Users of Xiaomi, Redmi and POCO smartphones face this phenomenon regularly, especially after updating the MIUI or HyperOS shell. Critical errors can occur in both heavy games and simple messengers, indicating the systemic nature of the failure.
The main reasons why the system is forced to terminate processes can be several: from a banal lack of RAM to deep conflicts of system files. Aggressive energy saving optimization introduced by engineers of the Chinese company often mistakenly labels active programs as “parasitic”, closing them to save battery power. Understanding the mechanism of the background processes is the first step to solving the problem.
In this article, we will look at all possible error scenarios in detail and suggest proven methods for fixing them. You don't need to be a technician to perform the proposed actions. We will look at both software methods for setting up and more complex procedures that require attention. Statistics show that in 85% of cases, the problem is solved by cleaning the cache and reconfiguring memory management without having to reset to factory settings.
The effect of overflow of RAM on the stability of work
One of the main reasons apps are dropping out is a critical lack of free RAM (RAM). When the volume of processes running exceeds the available limit, the Android operating system begins to force the background tasks to free up resources for an active window. On budget models with 3 or 4 GB of memory, this happens especially often.
The MIUI shell memory management system works on a first-come-first-out principle, but with strict restrictions: If you keep a browser with a dozen tabs, a navigator and a heavy game open at the same time, conflict is inevitable. The system simply kills the application process that consumes the most resources at the moment.
You can use built-in developer tools or third-party utilities to diagnose your current memory state, but it’s worth remembering that constantly cleaning up the memory completely is also harmful, as the system has to reboot system services, which puts additional strain on the processor.
- 📉 Close unused tabs in the browser, as they occupy a significant amount of space. RAM.
- 🔄 Reboot the device once in a while 2-3 Day to reset system processes and clean fragmented memory.
- 🚫 Turn off automatic start-up for rarely used apps through settings.
- 📱 Remove desktop widgets that constantly update data in the background.
Importantly, some applications have memory leaks when they do not release the resources they have been using after they are done, which leads to a gradual filling of the available volume and, as a result, to the instability of the entire system.
Aggressive battery optimization and MIUI energy saving
The MIUI shell and the new HyperOS are famous for their tight energy-saving policies. The system's algorithms constantly monitor energy consumption with each running process. If an application consumes charge in the background, the system can interpret this as an anomaly and force the process to end, which the user perceives as a departure.
Often the problem lies in the settings of a particular application. By default, many programs are not allowed to run in the background or use data in standby mode, this is especially true for instant messengers, email clients and navigators who need a constant connection to the server.
⚠️ Warning: Disabling battery optimization for too many apps can lead to a significant decrease in smartphone autonomy.Configure exceptions only for really important programs.
To prevent critical applications from being shut down, manually changing their power consumption will signal to the system that this process is a priority and should not be stopped even when the battery is low.
- 🔋 Go to Settings. → Annexes → All applications and select the desired program.
- 🔋 Click on Battery Consumption and select No Limits mode.
- 🔋 Enable AutoRun option in the same app settings menu.
- 🔋 Secure the app in the list of recent tasks by pulling the card down or pressing the lock.
☑️ Setting up energy saving
Also check the global battery settings. In Settings → Battery → Settings (or through three dots in the corner) make sure that the ultra-power saving mode that blocks most background services is not activated.
Cache conflicts and damage to application files
Accumulation of temporary files or their corruption is a common reason why an application closes immediately after launch.Cash is designed to speed up work, but if you write errors or crashes in the file system, it can contain incorrect data that leads to the crash of the program.
This is especially true after an application update fails through Google Play or GetApps, when new files are overlaid on older configurations, resulting in a conflict of versions of libraries, and the application cannot be properly initialized.
To solve the problem, you don't have to delete the program completely. Just clear the cache and data. However, it is worth remembering that cleaning the data will return the application to state immediately after installation, removing your logins, settings and progress (if it is not stored in the cloud).
| Action. | What's removed | Impact on the account | Recommendation |
|---|---|---|---|
| Clearing the cache | Temporary files, thumbnails | Safe, entrance is maintained. | First action in case of errors |
| Clearing the data | Settings, logins, database | Re-entry required | If cleaning the cache didn't help |
| Deletion of the annex | All application files | Re-installation required | With a complete failure of work |
| Resetting preferences | Settings for all applications | Resetting permits and defaults | Systemic conflicts |
You can clean through the Settings menu → Applications → All Apps → [Select App] → Clean. If a problem occurs in many programs, it makes sense to reset application preferences in the system settings.

Problems of compatibility and update of the Android system
Unstable work often occurs after updating the Android operating system or the MIUI shell. App developers do not always have time to adapt their code to new versions of the API provided by Google, as a result, on new smartphones or after an update, old versions of programs may not work correctly.
Also important is the version of the application itself, if you use a modified version of the program (mod, hacked game) or install it. APK-The file is from an unverified source, the probability of departures increases many times, such versions are not certified in Google Play Protect and may conflict with the system security libraries.
Check for updates in the official Google Play Store. If the problem appeared immediately after the system update, you may want to wait for a patch from the app developer or roll back!
💡
If the app crashes after a system update, try removing the app updates through the Three Dots menu in your Google Play profile, returning it to the factory version, and then updating again.
In some cases, cleaning up Google Play services helps. Go to Settings → Apps → All apps → Google Play Services → Memory → Clear all data. This will reset your sync settings and can eliminate version conflicts.
The influence of third-party software and superuser rights
Installing applications to “accelerate,” “cool,” or gain root rights often destabilizes the system, interfering with the Linux kernel on which Android is based and can block legitimate processes as malicious or redundant.
The presence of a modified bootloader or custom Recovery can also cause errors in the verification of the integrity of applications. Bank applications and programs with a high degree of protection (Google Pay, banking customers) can not only fly out, but also completely refuse to run on the modifi!
💡
The presence of root-rights or unlocked bootloader is the most common reason for the failure of banking applications and games with anticheat.
If you have installed launchers (desktop shells) or themes, try temporarily returning to the standard MIUI launcher. Third-party shells may incorrectly handle system window calls, causing the crash of the running application.
- 🛡️ Remove the software and antivirus if you use a standard defense system MIUI.
- 🛡️ Check the list of applications with access to special features (Special Access).
- 🛡️ Turn off overlays (overlays over other windows) in special features settings.
- 🛡️ Remove newly installed programs that may have caused conflict.
Cardinal measures: Resetting and flashing the device
If none of the above methods worked, system files may have been damaged or a serious error occurred in memory partitions, in which case it remains to perform a full reset to the factory settings (Hard Reset), this action will delete all user information, so be sure to make a backup copy of the data.
Before reset, you should check the file system. You can do this through the Recovery menu. To log in, turn off your phone and press the Volume Up + Power button combination (on the device off). From the menu, select Wipe Data.
⚠️ Warning: Wipe All Data permanently deletes photos, contacts and files, and make sure you save important data to the cloud or computer before starting the procedure.
In extreme cases, when even resetting does not help, you need to completely flash the device through the computer using the Mi Flash Tool utility. This will return the phone to the state of “out of the box”, replacing all system partitions with a fresh copy of the firmware.
