Owners of Xiaomi, Redmi and Poco smartphones periodically face an unpleasant situation when a running application suddenly closes, and a system notification appears on the screen that a failure has occurred. This message can occur both in standard components of the MIUI or HyperOS operating system, and in third-party programs downloaded from the Google Play store. Ignoring this problem often leads to unstable device operation, loss of unsaved data and reduced overall performance of the gadget.
The causes of critical errors can be very different: from the banal overflow of RAM to deep conflicts in system files after a failed update. App failure is an Android security mechanism that forcibly stops the process so that it does not damage other services or put the battery in zero. Understanding the nature of the error is the first step to successfully restore the health of your smartphone.
In this article, we will take a look at all the current troubleshooting methods, from simple actions that are available to any user to advanced settings through the engineering menu. In 85% of cases, the problem is solved by simply cleaning the cache of a particular application or resetting it to factory settings without losing personal data. Follow the instructions consistently to avoid unnecessary complications.
Analysis of the causes of errors
Before we start to actively restore, we need to understand what is causing the instability. Most often, the culprit is accumulated software debris that conflicts with new versions of libraries or the operating system itself. The application cache is designed to speed up work, but over time it can become corrupted, containing incorrect data that the system cannot process correctly.
Another common cause is version conflicts. MIUI, but the application remains the old version (or vice versa), incompatibility may occur in the API-Also, consider the lack of free internal memory: when critically filled, the system has no place to create the temporary files needed to run the programs.
An unstable Internet connection can also cause errors, especially in applications linked to online services. If the server does not respond in time, the application can "hang" in anticipation and be forcibly closed by the system by timeout, in rare cases, the cause is corrupted firmware files or virus software.
- 📱 Overflow of RAM with background processes.
- 🗑️ Damage to temporary files and application cache.
- 🔄 Conflict of software versions after partial system update.
- 🌐 Unstable network connection when online services work.
⚠️ Note: If an error occurs immediately after installing a new app, there is a high probability that it is not optimized for your version of Android or contains software bugs.
Basic methods of troubleshooting
The first and most effective step, which helps in most cases, is to completely reboot the device. This action clears the RAM, completes all the hanging processes and re-initializes the system services. To perform the reboot, press the power button and select Reboot in the menu that appears.
If the reboot didn't work, the next step is to check for updates. Developers are constantly releasing patches to fix known bugs. Go to the Google Play Store, go to profile and select App and Device Management to update all programs. For system components, the path is through Settings → About Phone → MIUI version.
Also worth checking is that your smartphone is full of memory: delete unnecessary photos, videos or heavy files that block the normal operation of the system. Freeing up at least 1-2 GB of free space often works wonders with the stability of applications.
☑️ Primary diagnosis
Cleaning the cache and data of the problem application
When a crash occurs in a particular program, the most effective method is to force the shutdown and clean up its data, which does not delete your account, but resets the application settings to the “just installed” state. To do this, go to the Settings menu → Applications → All applications and find the desired software.
In the management menu that opens, select Memory. Here you will see the two main buttons: Clear cache and Clear all. Start by clearing the cache, which is safe and only deletes temporary files. If persists error, use Clear all function, but remember that this can reset your personal settings inside the application.
Once cleaned, make sure to reboot your smartphone completely so that the system can redistribute resources correctly, and if the problem is caused by damage to the application database, this method should eliminate it completely.
| Action. | Impact on data | Recommended use |
|---|---|---|
| Clearing the cache | Secure, data is stored | At the first sign of failure |
| Clearing all data | Resetting the application settings | If cleaning the cache didn't help |
| Removal of updates | Return to the factory version | For errors after the update |
| Reinstallation | Complete removal and new installation | Critical system errors |
What to do if the cleaning button is inactive?
Developer settings and background activity limitations
MIUI is known for its aggressive energy saving policy, which can force applications to close as pests. To prevent this, you need to adjust the battery settings for important software. Go to Settings → Battery and Performance → Battery Savings applications.
Find the problem app in the list and select No Limits mode, which will allow the program to run in the background and use the necessary resources without system intervention, and go to the Permissions menu and make sure that the application has access to memory, microphone and other necessary functions.
For advanced users, the Developer Menu is available, which is activated by clicking seven times on the build number in the About Phone section, and you can find the Do Not Activity option, which you need to turn off if it is active, which will prevent the process from being destroyed when you switch between windows.
- 🔋 Setting the "No Limits" mode in the battery settings.
- 🔒 Verification and issuance of all necessary permits.
- 🛠️ Disabling the option “Do not remain active” in the developer menu.
- ⚡ Block Auto-Run for Unnecessary Programs.
⚠️ Warning: Enabling too many apps in No Limits mode can significantly reduce your device’s battery life from a single charge.
Radical measures: resetting and reflashing
If none of the softer methods worked, the problem may lie deeper in the system files, which may require a full reset to the factory state (Hard Reset).
To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The device will reboot and start the cleanup process, which can take 10-15 minutes. Once turned on, the phone will be like new, and you will need to reset accounts and install apps.
In extreme cases, when even resetting does not work, you need to flash the device through your computer using the Mi Flash Tool utility. This is a complex procedure that requires an unlocked bootloader and follow the instructions accurately, so it is recommended to perform it only for advanced users or in a service center.
💡
A full reset eliminates 99% of software errors, but takes time to recover data and reset the device.
Prevention of disruptions in the future
To minimize the risk of future failures, try not to install applications from unknown sources. APK-files often contain code errors or malicious scripts that disrupt the stability of the system. Use only official Google Play or GetApps stores.
Regularly clean your smartphone memory of junk files using the built-in Security tool. Also, do not ignore system updates, as they often contain security patches and compatibility bug fixes.
Reboot your device periodically, at least once a week, allowing the system to reset accumulated errors in RAM and update system processes. Simple habits of care for the gadget will prolong its life and ensure smooth operation.
💡
Set a rule: if the application is unstable, don’t wait for the accumulation of errors. Immediately clear its cache — this takes 10 seconds, but saves from future failures.
