The situation when a working application suddenly closes on a smartphone Xiaomi or Redmi, is familiar to many users. This can happen in the middle of a game, during a video call, or when trying to open a banking service. Such glitches are annoying and can lead to the loss of unsaved data. The main reasons lie in the peculiarities of the shell MIUI, lack of free resources or software conflicts.
Unlike “clean” Android, Xiaomi’s proprietary firmware uses aggressive energy-saving algorithms that can forcefully stop background processes. Understanding why the system is killing an application is the first step to solving the problem. Often the culprit is a full cache or an outdated version of the app itself.
In this guide, we will analyze in detail the mechanics of errors, offer step-by-step diagnostic methods, and provide specific instructions for setting up the system. You don’t have to be a technical specialist to fix most glitches yourself using the built-in tools of your smartphone.
Analysis of the lack of RAM and the work of background processes
The most common reason for apps to suddenly close is a simple lack of RAM. When free RAM is exhausted, the operating system begins to forcefully terminate processes to free up resources for the current task. On budget Redmi models with 3-4 GB of memory, this happens especially often when using “heavy” applications.
The shell MIUI has a built-in memory cleaning mechanism, which the user can accidentally activate or configure too aggressively. If there are apps running in the background, the system considers them unnecessary. You can check the current state through the developer menu or special monitoring utilities.
⚠️ Attention: Constantly manually clearing memory through a widget on the desktop can paradoxically worsen the situation. The system wastes resources on restarting services, which leads to additional battery drain and software instability.
For stable operation of critical services, it is necessary to configure exceptions. Go to settings and find the autorun control section. Here you should allow apps that need to function constantly, for example, instant messengers or navigators.
Cache errors and corruption of temporary application files
During operation, any application accumulates temporary data, known as cache. Over time, these files can become damaged or take up a critical amount of internal memory, which leads to read errors and subsequent app crash. Clearing the cache is a secure procedure that does not delete your personal data, logins or passwords.
To perform a clear for a specific problematic application, go to menu Settings → Applications → All applications. Find the desired app in the list and click on “Storage”. Here you will see the “Clear cache” button, which must be activated.
- 🗑️ Clearing the cache deletes only temporary files, speeding up the launch of the app.
- 📂 Clearing data resets the application to its factory state, deleting accounts and settings.
- ⚙️ Regular maintenance helps avoid the accumulation of system garbage in the partition Android.
If clearing the cache does not help, you can try a more radical method - clearing data. Please note that after this you will have to log in to the service again. This method is effective when the app’s configuration files have received logical damage.
Before clearing the data, make sure that you remember the password for your account in the application, otherwise access may be lost forever.
Software version conflicts and MIUI system updates
Instability often occurs after updating the firmware or the application itself. Developers may release a version of the software that does not work correctly with the current version Android or shell HyperOS. It is also possible that system components Google Play Services are outdated and require updating.
Check for updates for all installed apps through the store Google Play or GetApps. Sometimes the problem is solved by rolling back the application to the previous version if the new one contains critical bugs. This may require downloading an older APK file from a trusted source.
| Update type | Probability of conflict | Recommended action |
|---|---|---|
| App update | High | Check reviews in the store, roll back the version |
| Update MIUI/HyperOS | Medium | Wait for a patch from Xiaomi, clear the system cache |
| Update Google Play | Low | Clear Google Play service data |
| Beta software version | Critical | Return to the stable firmware branch |
Particular attention should be paid to beta firmware versions. They often contain undocumented errors that affect the stability of third-party software. If you installed a test build MIUI Beta, consider returning to the stable update channel.
Energy saving settings and background activity restrictions
Energy saving systems in smartphones Xiaomi are configured for maximum autonomy, which often comes at the expense of performance. The “Power Saver” mode can limit the processor frequency and block the network activity of applications in the background, causing them to crash when trying to synchronize.
You can individually configure the battery saver profile for each application. Go to Settings → Battery → Application battery saving. Select the problematic app and set it to No Restrictions. This will allow the process to run in the background without being forced to sleep.
☑️ Setting up power saving
It is also worth checking the autorun settings. If an application does not have the right to autostart, the system may not allow it to initialize the necessary services at startup, which leads to a crash immediately after opening. Activate the autorun switch for important services.
⚠️ Attention: Giving full rights to run in the background and autorun many applications can significantly reduce the operating time of your smartphone on a single charge. Use this setting selectively only for really important apps.
Problems with permissions and access to system functions
Modern versions Android have strict requirements for access rights. If an app is not given the required permission (such as access to storage, microphone, or phone), it may not process system requests correctly and may crash. This often happens after resetting the settings or updating the OS.
Check the list of granted permissions in the application card. Make sure that all the necessary items are activated, especially memory access if the application works with files. Lack of access to the storage storage
In some cases, completely resetting permissions for all applications helps. This will return the access settings to the default state, and the next time you start the app they will request the necessary rights. This can be done in the menu Settings → Applications → Permissions → Reset settings.
Hidden permissions
In some versions of MIUI, there are hidden permissions for accessibility features that can affect the operation of overlays and pop-ups. Check the "Accessibility" section in the phone settings if the problem is related to interface overlay.
Hardware faults and processor overheating
If software methods do not produce results, the reason may lie in the hardware. Overheating The processor is a protective mechanism that throttles frequencies or closes resource-intensive applications to prevent component damage. This is typical for long gaming sessions or using a smartphone in bright sun.
It is also worth checking the status of the internal memory. If the storage is more than 90% full, the system cannot create page files and temporary buffers, leading to instability. Free up at least 10-15% of the space for the correct operation of the OS.
- 🌡️ Overheating causes throttling and emergency shutdown of heavy tasks.
- 💾 Clogged memory blocks the creation of system temporary files.
- 🔋 Battery degradation can cause voltage sags under load.
In rare cases, crashes indicate a faulty memory module or processor. If the phone heats up even when idle, and applications crash randomly, it is recommended to contact a service center to diagnose the hardware.
If crashes occur only in heavy games and are accompanied by strong heating of the case, the problem is 90% likely due to overheating and not a software failure.
Additional diagnostic methods and resetting settings
When all of the above methods have been exhausted, there remains the option of a more in-depth diagnosis. The built-in engineering menu allows you to check the condition of components. Enter the code ##6484## in the dialer to enter the CIT testing mode. Here you can test the sensor, memory and other components.
The last resort is to completely reset the device to factory settings. This will delete all data, so be sure to make a backup. After the reset, do not restore all applications from the backup at once, but install them one at a time, monitoring stability.
adb shell pm clear com.package.nameThis command, via USB debugging, allows you to completely clear the data of a specific package, which is sometimes more effective than the standard settings menu. However, use this method only if you are confident in your actions and know the exact name of the application package.
⚠️ Attention: The interface and location of menu items may vary slightly depending on the version of MIUI (12, 13, 14) or the new HyperOS. If you do not find the specified option, use the search in the settings by entering the name of the function.
Frequently asked questions (FAQ)
Why do applications crash immediately after installation?
This may be due to incompatibility between the application version and your version of Android, or a damaged installation file. Try downloading the app from the official Google Play store and not from third-party sources. Also check if there is enough free memory on the device.
Does deleting system updates help with crashes?
Removing system updates is only possible for some system applications (for example, Google Play Services), but not for the firmware itself without flashing it. If the problem started after updating the OS, it is better to wait for a patch from the developer or perform a factory reset.
Does developer mode affect application stability?
Yes, some settings in developer mode, such as limiting background processes or disabling animations, can affect the operation of software. If you enabled this mode, try resetting the developer settings in the corresponding menu.
What to do if only one specific application crashes?
Most likely, the problem is localized in the application itself. Clear the cache and data specifically for this app. If it doesn't help, uninstall and install it again. Also check for updates for this particular software.
Can a virus cause applications to crash?
Yes, malware can conflict with legitimate applications, consume resources, or infiltrate their processes. Conduct a full scan of your smartphone with the built-in Security antivirus or a third-party solution, for example, Dr.Web or Kaspersky.
