Apps fly to Xiaomi: reasons and 10 working ways to solve

Do you run your favorite app on Xiaomi, Redmi or POCO, and it suddenly shuts down after a few seconds? Or does the game crash on the boot screen? This problem is familiar to many device owners on Xiaomi's MIUI, the branded shell. The reasons can range from overloaded cache to firmware conflicts. In this article, we'll look at all the possible solutions, including hidden system settings that help even in the most neglected cases.

It’s important to understand that app departures are rarely connected to the hardware of a smartphone. 90% of the time, the software is to blame: incorrect updates, cache errors or aggressive battery optimization. We’ve compiled current methods for MIUI 14/15 (Android 13/14) that work on models from the Redmi Note 12 to the flagship Xiaomi 14 Ultra. If you tried to restart the phone and it didn’t help, read on.

1.Cleaning the app cache: the first step to stability

The most common cause of departures is overcrowded or corrupted cache. MIUI actively uses caching to speed up work, but sometimes this data conflicts with application updates. Clearing the cache does not delete your data (logins, saves), but resets temporary files.

How to do this:

• 📱 Open the Settings. → Annexes → Application management
• 🔍 Find the problem app in the list and tap it.
• 🧹 Choose Clear Cache (not to be confused with Clear Data!)
• 🔄 Reboot your smartphone

If the application still crashes after that, try to clear the cache of system services:

Settings → Memory → Cleaning → Cache of system applications

⚠️ Warning: Do not clear data without a backup – this will delete all settings and files of the application, including logins and game progression.

2. Disable battery optimization for problem applications

MIUI is known for aggressive background optimization, which often leads to forced closure of applications, especially for instant messengers, games and services with push notifications, the solution is to add the application to the exclusion list.

Instructions for MIUI 14/15:

• ⚡ Go to Settings. → Battery and productivity → Battery consumption management
• 🔧 Select Application Choices → Find the right application
• 🔄 Set the mode without restrictions
• 🔒 Turn on the Autostart switch (if any)

For older versions of MIUI (up to 12.5), the path may be different:

Settings → Battery → Battery settings → Battery optimization → All applications

3. Updating applications and systems: closing gaps

Departures are often due to version incompatibility, such as the game is optimized for Android 14 and your Redmi 9 is also on Android 11, or the app itself contains bugs that were fixed in the last update.

What to do:

1. Update the problem app via Google Play or GetApps (for Chinese firmware)
2. Check system updates: Settings → About phone → System update
3. If the MIUI update is available but not installed, try downloading the full firmware package through Settings → About Phone → MIUI Version → Three-point icon → Select the service pack

For devices with global firmware (EEA/RU), updates come automatically. On Chinese versions (CN ROM), you may need to manually install via Fastboot or Recovery.

4.Resetting the app settings: when nothing helps

If the cache is not cleaned, the next step is to reset the app, which will return it to the factory state, but save system data (such as Android versions), which is effective for applications that fly out when you launch or do not save settings.

Step-by-step:

Select the problem application in Settings → Applications

Put it on the vault and the cache.

Click Reset (or Clear All Data in English)

Confirm the action and restart the phone-->

After reset, you may need to re-enter your login/password. For games with cloud-based saves (such as Genshin Impact or PUBG Mobile), the data will be automatically restored the next time you run.

⚠️ Warning: Don't confuse Resetting app with Resetting all phone settings! The second option will delete ALL data from the device, including photos and contacts.

5. Virus and malware check

It's rare, but it happens: application crashes cause viruses or Trojans masquerading as system processes, especially if you've installed APKs from unverified sources. MIUI has a built-in security scanner, but it doesn't always detect all threats.

How to check:

• 🛡️ Launch Security → Scanner. → Deep inspection
• 🔍 Install a third-party antivirus (such as Malwarebytes or Dr.Web Light) and scan the system.
• 📁 Check the list of installed applications for suspicious names (e.g. com.system.update from an unknown developer)

If you find malware, delete it and restart the phone, and then check the problem apps.

Disable MIUI Optimization (for advanced users)

One of the hidden reasons for departures is the built-in MIUI Optimization feature, which conflicts with some applications, and you can only turn it off via ADB (Android Debug Bridge), a method recommended if you have tried all other methods.

Instructions:

1. Turn on Developer Mode: Settings → About Phone → MIUI Version (shap 7 times)
2. Activate USB Debugging in Settings → Additional → For Developers
3. Connect your phone to your PC, install ADB drivers and open the command line
4. Enter the command: adb shell settings put global miui_optimization_disabled 1
5. Reset the device

Once optimization is disabled, some MIUI animations may run slower, but application stability will improve. To get it back, run the same command with 0 instead of 1.

💡

If you don’t have access to a PC for ADB, you can use the Shizuku + MIUI Optimization Toggle app from Google Play, which will disable computer-free optimization, but will require root rights or special permissions.

7. Reinstallation of the problem application

If none of the methods worked, it leaves you with a complete reinstallation. This will delete all of the application data, so back up in advance (e.g., via Settings → System → Backup).

How to properly reinstall:

• 🗑️ Remove the application through Settings → Applications (not just from the desktop!)
• 🔄 Reboot the phone.
• 📥 Install the app again from the official store (Google Play, AppGallery or GetApps)
• 🔓 At the first start, provide all necessary permissions.

For games with large data files (like Call of Duty Mobile or Genshin Impact) you may need to re-download additional files after reinstalling.Use Wi-Fi to avoid wasting mobile traffic.

8.Extreme measures: reset to factory settings

If the application crashes are a systemic problem and affect most programs, the firmware itself is probably damaged, and then only a full reset will help.

Create a backup through Settings → Google → Backup

Copy photos/videos to PC or cloud

Write down logins/passwords from important services

Make sure you're on balance. SIM-enough funds (reset can reset mobile network settings)-->

How to perform the reset:

Settings → About the phone → Reset settings → Erase all data

Once reset, the phone will reboot and prompt it to be set up as new. Don't restore data from the backup right away - first check if the problem apps are working out of the box. If so, the data can be returned in stages.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 8 Pro) POCO F1) After reset, you may need to re-unblock the bootloader if it was done before!
