Apps on Xiaomi do not open: a complete guide to elimination

The situation when Xiaomi smartphone suddenly stop running programs, familiar to many owners of devices with shells MIUI and HyperOS. You click on the icon, but the screen just flashes, or worse, the system immediately throws you back on the desktop. This can happen to one particular service, and the whole system, turning an expensive gadget into a useless piece of plastic.

Most often, the cause is not a hardware breakdown, but a software conflict or a system memory overflow. The aggressive battery optimization that Xiaomi is famous for sometimes perceives important processes as malicious and blocks them from working. Other times, legacy components of the Android System WebView system or damaged cache files accumulated over months of use are to blame.

Before you take your device to a service center or look for a master, you should try a comprehensive diagnostics yourself. In this article, we will discuss effective methods to help restore the functionality of your favorite applications without losing personal data.

Primary diagnosis and basic reboot

The first and often ignored step is to fully reboot the device, and many users simply turn off the screen, leaving the phone in standby mode for years, but the operating system, like any computer, needs to periodically clean up RAM from temporary files and suspended processes.

If a conventional shutdown didn't work, try a hard reboot. Press the power button and the volume button at the same time and hold them for about 10-15 seconds until the device vibrates and the Mi or Redmi logo appears. This method allows you to reset static electricity and forcefully close all background tasks that could block the start of programs.

⚠️ Note: If after a restart, the phone begins to warm up strongly in the processor area, and the applications still do not open, it is possible that the problem is hardware in nature and is associated with overheating of the motherboard.

Also worth paying attention to is the amount of free internal memory: when the storage is over 90% full, the system starts to work unstable, the operating system simply cannot create the temporary files necessary to run programs, delete unnecessary videos or transfer the photo to the cloud to free up at least 2-3 GB of space.

Cleaning the cache and data of the problem application

The most common cause of failure is damage to temporary files of a particular service. cache speeds up work, but over time it accumulates errors that prevent a correct start. To fix this, go to the Settings menu → Applications → All applications and find the problem program in the list.

Inside the app menu, you'll see two important buttons: "Clean" and "Delete." We're interested in the first one. Click on it and select the option "Clear Cache." This is safe and won't delete your logins or game progress. If that doesn't work, use the Clean Everything (or "Reset") feature, but remember that this will return the app to state immediately after installation.

• 📱 Go to the settings of a particular application through the main screen.
• 🗑️ Select "Memory" or "Storage" in the action menu.
• 🔄 Press the cache clean button and confirm the action.
• ⚙️ Check if the program has opened after the procedure.

💡

Before completely clearing the data (not the cache, but the data), make sure that you remember the password from the account in this application, as you may be thrown on the authorization screen.

Once the data is cleaned, the application can run slower in the first minutes, because it has to re-download the necessary resources. This is normal behavior. If the problem was broken configuration files, then after reset, the program should start without errors. In rare cases, you need to repeat the procedure 2-3 times in a row.

Update of system components and Google Play

Often the culprit for not opening applications on Xiaomi is not the program itself, but the system component of the Android System WebView, which is responsible for displaying web content within applications, and if it is outdated or does not work correctly, many services simply stop responding to clicks.

Go to the Google Play Store, click on your profile avatar and select “Apps and Device Management.” In the “Update Availables” section, search for Android System WebView and update it. It is also recommended to update the app store itself and Google Play services, as they are responsible for licensing and operating many features.

Also, check for updates to the MIUI or HyperOS shell itself. Developers regularly release patches to fix compatibility errors. Go to Settings → About the phone and click on the system version. If a new update is available, install it by pre-connecting to Wi-Fi and charging the battery.

Energy saving and permits settings

Xiaomi’s aggressive energy saving system often blocks the background activity of applications as malicious or ineffective, causing the program to fail to start the necessary processes and crashes, and to prevent this, you need to manually adjust the restrictions for important services.

Go to the battery settings and find the "Application Energy Saving" section. Find the right program and set the "No Limits" mode. This allows the application to use the CPU resources even when it's rolled down or just starting up. Without this step, optimization can permanently kill the startup process.

⚠️ Warning: Installing No Limits mode can lead to increased battery consumption if the application is not optimized by the developer.

Also check permissions. Some applications can't open unless they're given basic permission to access memory or network. In the permission menu, make sure the switches in front of the right points are activated, especially for instant messengers and banking applications.

Reset application settings and safe mode

If none of the previous methods worked, there may have been a deep software failure, in which case you can try resetting all the apps at once, and this action will not delete your personal files, photos or contacts, but will return all system preferences to factory values.

To do this, go to Settings → About Phone → Reset and select Reset All Settings (not to be confused with a full factory reset that erases everything!). After this operation, the phone will reboot and you will have to reset Wi-Fi and alarm clocks, but this often solves the problem with launches.

Another way to diagnose this is to run in Safe Mode, and if it opens normally, it means that some third-party application you recently installed is in conflict, try to remove the latest downloaded programs or those that have broad screen access rights (such as memory cleaners or third-party launchers).

Removal of updates and re-installation

Sometimes the problem is the update itself, which is "bug" and developers can release an error version that is incompatible with the current version of MIUI, in which case the logical step is to roll back to the previous version or completely reinstall.

Go to the app page on Google Play, click on the three dots in the top right corner and select "Remove Updates" (if available), or simply uninstall the app completely. Once removed, restart your phone and download the fresh version again, which ensures that all relevant libraries are installed.

• 📉 Remove the current version of the application from the device.
• 🧹 Clear the remaining files through the file manager (folder) Android/data).
• 🔄 Reboot your smartphone to clean up system buffers.
• 📥 Install the latest stable version from the official store.

💡

A complete reinstallation of the application with the pre-cleaning of residual files solves 80% of problems with “non-opening” programs on Xiaomi.

If you are using apps outside of Google Play (such as those downloaded from your browser), make sure you have the latest version of the package installer installed. Older versions of the installer may not properly handle new application signature formats, leading to a silent refusal to start.
