Suddenly shutting down programs is one of the most common problems faced by owners of Xiaomi and Redmi smartphones: When you just started chatting or watching videos, and the app abruptly closes and returns you to the home screen, it is very annoying, and this can happen with both preinstalled software and heavy games or banking customers.
The reasons for this behavior of the Android operating system in conjunction with the shell of MIUI or HyperOS can be completely different, often due to overcrowded RAM, accumulated software debris or aggressive power saving settings. In some cases, the problem lies in the incompatibility of software versions or damage to system files after a failed update.
In this article, we will go into all possible scenarios and propose specific solutions: you will learn how to diagnose the device yourself, adjust the background processes correctly, and perform deep error reset without losing important data.
Primary diagnosis and forced reset
Before you go to complex manipulations, you need to perform a basic system reboot, which clears the RAM and forcibly closes all the suspended background processes that could cause the conflict, and many users ignore this step, although it solves up to 40% of the problems with the instability of the interface.
If the phone is responding to touch, just press the power button and select Turn off or Reset. In cases where the sensor is not responding, use hardware reset: press the power and volume buttons simultaneously for 10-15 seconds until the device vibrates and the Mi logo appears.
⚠️ Note: If only one particular app is coming out and the rest are running smoothly, don't rush to reset the entire phone to factory settings.
After activation, wait 2-3 minutes until the system fully loads all services of Google and Xiaomi. Check the problem program. If the error repeats, proceed to the following sections of the instructions for a deeper analysis.
Memory management and cache cleaning
Lack of free memory is the most likely reason why apps are coming to Xiaomi. When the free space in the RAM partition ends, the system forcibly closes active processes to free up resources for the Android kernel, especially for models with 3 or 4 GB of RAM.
You need to check which programs consume the most resources, go to the settings and find the memory section, and you can see a list of the most "heavy" applications, often social networks like VK or Telegram, and browsers with many open tabs.
To clean the cache of a particular application, perform the following steps:
- 📱 Go to the Settings menu and select "Applications».
- 🔍 Find the problem program in the list and click on it.
- 🧹 Select the option “Memory” or “Storage”, then click “Clear Cache».
- 🗑️ If this does not help, you can try to click “Clean everything” (this will reset the settings of the application to the factory).
You also need to use the built-in optimizer. Open the Security app, which is pre-installed on all Xiaomi smartphones. Click the Cleanup button to remove system debris, and Accelerate to close background tasks. This action often returns the system to the required performance.
☑️ Memory check
Power saving settings MIUI and HyperOS
The MIUI shell and the new HyperOS are known for their aggressive battery management policies, which aim to maximize battery life by ruthlessly killing background processes, which may prevent instant messengers from sending notifications and allow games to fly out minutes after launch.
To prevent the system from closing programs that are important to you, you need to change the battery settings for each application separately, which is especially important for navigators, activity trackers and work messengers, and without this setting, Android will consider the application inactive and turn it off.
The energy saving algorithm is as follows:
- 🔋 Open the Settings. → Annexes → All applications.
- 📲 Select the desired application from the list.
- ⚡ Find the item "Energy saving».
- ✅ Set the value "No restrictions».
What is extended memory?
Also, check the general power saving mode. If it's on, the CPU's performance is artificially limited. Switch to Balanced or Performance mode in the Battery menu, which allows applications to use maximum CPU power without trottling.
Updating and reinstalling problematic applications
Often the cause of instability is an outdated version of the app itself, or, conversely, a raw beta bill that contains bugs. Developers regularly release patches that fix departures on specific device models, so the first step should be to visit the Google Play store or GetApps.
If the application is updated to the latest version, but it still doesn't work properly, a complete reinstallation will help, so it's not just to update the program on top of the old one, but to completely remove it by clearing the remaining files and installing it again, which ensures that the old configuration files don't conflict with the new ones.
Procedure for reinstallation:
- 📥 Remove the app via the menu or long-click on the icon.
- 🔄 Reboot your smartphone to clean system links.
- 🌐 Download the latest version from the official source.
- 🔐 At the first launch, provide all the requested permissions.
💡
If the app crashes right after installation, try rolling back to the previous stable version. APK-Older versions can be found on verified archives, but be careful about data security.
In some cases, the problem may be with Google Play. If departures are random across different programs, try to clear the app store data. Find the Google Play Store in the app list, click Memory and select Clear Everything. This is safe and won't delete your purchased programs.
Working with system updates and rollback
It is not uncommon for new versions of MIUI to have optimizations that conflict with the current set of installed applications. In the first 2-3 days after a major update, the system performs background indexing and optimization, which can cause lags.
Check for new security patches. Often Xiaomi will release quick fixes for critical bugs. Go to Settings → About the phone and click on the system version. If an update is available, install it.
However, if the problem occurred after the update and is not solved for a month, perhaps the new version of the firmware has a bug. In this case, it is worth considering the possibility of rolling back on the previous version, although this is a complex procedure that requires unlocking the bootloader. For most users, it is easier to wait for the next patch.
| Type of problem | Probable cause | Method of decision |
|---|---|---|
| Departure after update | Cache conflict | Clearing the cache of all applications |
| Relegation in the games | Lack of RAM | Closing of background applications |
| Departure of the system menu | System error | Reset to factory settings |
| Departure of one application | Bug in the program code | Reinstallation or waiting for a patch |
💡
If the flights started after the firmware update, give the phone 2-3 days for background optimization. If the problem does not disappear, do a reset.
Cardinal measures: Reset and engineering menu
When software methods fail, the last resort is a hard reset, which will bring your phone back out of the box by deleting all your photos, contacts, and installed programs, and make sure to back up your data to the Xiaomi Cloud or your computer before doing so.
To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The phone will reboot and start the cleanup process, which can take up to 15 minutes. Once turned on, the system will be clean, without third-party software, which will allow you to check whether the problem is in hardware or third-party software.
⚠️ Warning: Make sure the battery is over 50% before starting a reset.Stopting the data writing process can damage the system partition and turn the phone into a "brick».
There is also a hidden engineering menu available through code ##6484##, which can run memory and processor tests, and if tests show errors (e.g., red lines in the results), the problem may be physical, such as a memory module malfunction or a processor overheating, in which case the software methods are powerless and a visit to the service center is required.
For advanced users, a reset is available via Recovery Mode. To do this, turn off your phone and press Volume Up + Power. From the menu, select Wipe Data. This is a deeper level of cleaning that helps in cases where the system does not boot normally.
