When your favorite messenger, banking app or game suddenly stops running on a Xiaomi smartphone, it can knock anyone out of their way. The screen can blink back to your desktop, or you will see a system error notification with the code. In the MIUI operating system and the new HyperOS, many background processes are responsible for the stability of programs, the failure of which leads to such symptoms.
The problem is often not physical device failure, but software conflict or cache overflow. The aggressive power optimization characteristic of Xiaomi shells can force the system to close processes that it considers “hard” or unnecessary. Understanding the mechanism of the background services is the first step to restore the functionality of the gadget.
In this article, we will take a closer look at all possible causes, from simple memory shortages to complex system errors, and provide step-by-step instructions for fixing them. You don’t need to be an expert in android to perform the steps below and return your phone to normal.
Overflow of operational and internal memory
One of the most common reasons applications crash immediately after launch is a critical lack of free resources: when internal memory is almost full (less than a few days left). 1-2 GB), the operating system cannot physically create the temporary files needed to initialize the program (RAM) It also plays a key role: if all available threads are occupied by background processes, the new application simply has nowhere to start.
Android is designed to require air to run any software, free space to swap and caching data, and if you ignore space warnings, the phone slows down and then the apps crash, and it's a defense mechanism to prevent the system from crashing completely.
To diagnose a problem, you need to check the status of the storage, go to the settings and find the partition responsible for the memory of the device, if the scale is filled in red, you need to clean immediately.
- 🗑️ Remove unnecessary photos and videos by moving them to cloud storage or computer.
- 📲 Clear the cache of instant messengers (Telegram, WhatsApp), which often take up gigabytes of space.
- 🚫 Uninstall rarely used games and heavy apps.
- 🔄 Check the Downloads folder where browser debris often accumulates.
Once the space is free, it is recommended to restart the device so that the system can redistribute file indexes, often after this simple procedure, applications begin to open instantly.
Failures in the operation of a particular application and cache
If you only have one or more programs and the rest of the phone is working properly, it's a local data failure, because you accumulate temporary files that can get corrupted over time, and the cache is designed to speed up the work, but when it's damaged, it becomes a source of errors.
Also, after an operating system update, older versions of applications may not work properly due to changes in system libraries, in which case you need to reset the settings of a particular application, which is safe and will not delete your personal correspondence or game progress (if stored in the cloud), but will return the program to factory settings.
⚠️ Note: When clearing the data of some applications (such as banking or authorization), you may need to re-enter your login and password.
To do the cleaning, go to the phone's settings menu. Find the Apps section and select All Apps. In the list, find the problem program and click on it.
In the menu that opens, select Memory, where you will see two buttons: Clear cache and Clear all data. Start by clearing the cache. If that doesn't work, use a full data cleanup.
☑️ Checklist for fixing application failure
It’s also worth checking for updates for the app itself in the official Google Play store or GetApps. Developers often release patches that fix compatibility with newer versions of Android.
Version Conflicts and System Updates
Often, when applications stop opening, it happens immediately after the firmware update of the phone or the application itself. A new version of the MIUI or HyperOS operating system may contain changes to the APIs that older versions of programs do not support, in which case there is a conflict of versions.
The reverse is also possible: you have upgraded the app to a version that is not yet optimized for your current Android version. Software developers do not always have time to test products on all Xiaomi shell modifications, especially on global firmware versions.
| Type of problem | Symptoms. | Decision |
|---|---|---|
| Obsolete appendix | Departure with error code | Update via Google Play |
| Failure after OS update | Black screen at launch | Clear the application data |
| Incompatibility | Message "Application not supported" | Remove and look for analogue |
| The Google Play Error | It is impossible to download or update | Clear the Google Play cache |
In some cases, waiting helps. If the update has just come out, developers can release the fix within a few days. However, if the problem is critical, you can try to roll back the application to the previous version by downloading it. APK-file from a reliable source, but it requires caution.

Aggressive optimization of the MIUI battery
A unique feature of Xiaomi smartphones is its highly aggressive energy-saving policy, which attempts to extend battery life by forcibly closing the background processes, which sometimes works too hard and blocks applications from running as “energy eaters.”
If an application doesn’t open or closes immediately after opening, it may have been blacklisted by an optimizer, which is often the case with instant messengers, navigators, and smart home apps that need a permanent connection to the server.
To fix this, you need to configure exceptions for important programs. Go to Battery and Performance (or simply Battery) and find the gear icon or Settings menu.
- 🔋 Select “No Limits” mode for important applications.
- 🚀 Turn off Advanced Optimization in the Developer Menu (if enabled).
- 🔒 Block the application in the menu of running tasks (pull down on the application card).
- ⚙️ Check Auto Start: Allow the app to start automatically.
💡
Setting up the “No Limits” mode for the application is the most effective solution for Xiaomi if the program is closed by the system immediately after launch.
After changing these settings, the system will stop “smothering” the background processes of the selected application, which should solve the startup problem.
Problems with Google Services and Date
Many modern applications (maps, YouTube, banking software, Play Market store) are critically dependent on the correct operation of Google services. If the Google Play Services framework fails, dependent applications can simply not run, leaving for an endless download or departure.
Another common but common cause is a lost date and time: Security protocols (SSL/TLS) used by applications to connect to a server require that the device time match the actual time, so if the date is downed, the server rejects the connection, and the application closes with a network error.
Check the date and time settings. It's recommended that you set up automatic time determination over the network, which will eliminate human error and time zone errors.
If Google services are a problem, try clearing their cache, search the Google Play Services list and clean the cache and data, and check if the antivirus or firewall is blocking the connection.
⚠️ Note: Do not disable Google system components completely if you use an official app store.
Malware and access rights
While Android is considered a fairly secure system, installing applications from unknown sources is a very safe and secure system (APK-forum files, Telegram channels carry risks. Malware can be embedded in legitimate applications, causing them to work unstable or block the launch of other security programs.
In addition, some applications require specific permissions to work, and if you have previously denied an application access to memory, microphone, or network, it may not start because it cannot initialize the required components.
Check the permission list for the problem application, make sure it has access to storage and network, without which modern software can not work.
It's also worth running a built-in antivirus. In Xiaomi smartphones, it's integrated into the Security app. Run a full threat scan.
💡
If you installed the app shortly before the problem occurs, try to remove it, and it is often the new, poorly optimized software that causes conflicts.
