The situation when a favorite app suddenly closes on the screen of Xiaomi Redmi, familiar to many users. This can occur at the most inopportune time: during an important conversation, passing a level in the game or when paying for a purchase in the store. Users often encounter the message “App stopped” or simply return to the desktop without warning, this behavior of the system is not only annoying, but also disrupts the workflow, forcing them to look for the causes of instability.
The main problem lies in the peculiarities of the MIUI shell, which aggressively manages resources to save battery power. Unlike pure Android, Xiaomi often forcibly terminates background processes, considering them unnecessary. However, sometimes the necessary services fall under the “knife” of optimization, which leads to malfunctioning programs. Understanding the mechanisms of memory and processor will help eliminate most failures.
Don't panic and bring your smartphone to the service center. 90% of the time, the problem is solved by software methods that are available to every owner. Android system partition can be damaged after a failed update or power failure, which requires a Dalvik cache reset. Next, we will discuss all possible causes and provide step-by-step instructions to restore the stability of your device.
Lack of RAM and overflow of storage
The most common reason why applications fly out on Redmi Note or older models is a banal lack of resources. Android requires a certain amount of free RAM (RAM) to run and operate programs. If the free space runs out, the system begins to forcibly close active processes to free up resources for the current task.
Special attention should be paid to the internal memory of the device. When more than 90% of the available space is filled, the speed of writing and reading data drops critically, which leads to the fact that the application does not have time to save temporary files or download the necessary libraries, resulting in an emergency shutdown. Flash memory in smartphones runs slower when overflowing, which causes lags and departures.
- 📉 Closing background apps via the multitasking menu frees up to 30% RAM.
- 🗑️ Removing unnecessary photos and videos directly affects the speed of the system.
- 🚫 Disabling automatic application updates in the background reduces the load on the processor.
To diagnose the current state of memory, you can use built-in tools or third-party utilities. It is important to regularly audit installed programs. Often users forget about applications that hang in the background and consume resources, although they are not used for months.
It is worth noting that some heavy games and video editors require a significant amount of RAM. If the device has 3 or 4 GB of memory, running such programs against the background of other tasks is almost guaranteed to lead to a flight, in such cases, you need to close everything unnecessary before running resource-intensive software.
Android Version Conflicts and MIUI shells
Often, problems with launching programs arise after an operating system update. The new version of MIUI may contain bugs or changes to the API that are incompatible with the installed version of the application. Software developers do not always have time to quickly adapt their products to the new requirements of Xiaomi, which leads to instability.
This is especially true for devices that have upgraded to the new major version of Android (e.g. 11 to 12 or 13) and older versions of apps may not work properly with new security resolutions or memory management mechanisms, so check for updates for a particular application in the Google Play store.
⚠️ Note: If a system application (such as "Settings" or "Phone") crashes after updating your firmware, do not immediately try to reset completely.
Sometimes it helps to roll back an application or install an older but stable version from trusted sources. However, the most reliable way is to wait for a patch from the developer. It is also worth considering that global firmware (Global ROM) errors can occur less often than on Chinese versions (China ROM) with a third-party language package installed.
How do I check the MIUI version?
Errors in cache and application data
Cache is another common cause of failures: Cache is designed to speed up the loading of commonly used items, but over time it can grow to giant sizes or contain broken data. When an application tries to access a corrupt file in the cache, a critical error and forced closure occurs.
Clearing the cache is a secure procedure that doesn't delete your personal data, logins or passwords. It only deletes temporary files. However, clearing the "Data" of the application will return it to a state immediately after installation, requiring re-authorization. These two functions are often confused, but it is the cache that you need to start with to solve the problem of departures.
You can clean up through the settings menu, and the sequence of actions is: Settings → Applications → All applications. In the list that opens, you need to find the problem program and select "Clean" and there will be two buttons: "Clear cache" and "Clear all data."
☑️ Algorithm for cleaning problem applications
If a simple cache cleanup didn't work, a deeper cleanup can be done, and in some cases, removing updates to system components like the Android System WebView helps, which is responsible for displaying web content within applications, and its failures often cause multiple programs to crash at the same time.
MIUI's aggressive energy-saving policy
A unique feature of Xiaomi smartphones is its extremely stringent energy management policy, which seeks to extend battery life by artificially limiting background activity. To the user, this can look like a bug: the app simply stops working if you switch to another screen or lock your phone.
To prevent departures, you have to add important applications to exceptions, and that's to the system that the software is important to the user and its processes can't be completed, and without that step, messengers can fail to get notifications, and navigators can lose their route.
| Setting up | Where to find out. | Recommended value |
|---|---|---|
| Auto-start | Security → Permits → Auto Startup | Included. |
| Saving energy | Settings → Battery → Applications | No restrictions. |
| Floating window | Settings → Special Opportunities | If necessary, |
| Protecting memory | Settings → Advanced settings → Memory | Don't clean. |
It is important to check the settings for each critical application separately. Global settings may not apply to all programs automatically, and it is also worth fixing the application in the menu of running tasks (usually this is done by swiping down the application window in the list of recent programs) so that the Clean All button does not affect it.
💡
Use the "No Limits" mode only for applications that need to work all the time (messengers, trackers). For games and videos, this mode is not mandatory and will only consume battery.
Conflicts of third-party software and malware
Install applications from unknown sources (APK-Modified versions of popular programs (game hacks, premium versions) often contain errors in the code that cause conflicts with the system libraries of Android.
It could also have been infected with a virus or an ad module, which can be disguised as system processes or legitimate utilities, which can be used in the background to load the processor and cause other applications to crash, and can be detected by pop-up ads on the desktop and a fast battery drain.
To diagnose, you can run your smartphone in safe mode, which only downloads system applications, and if you stop flying in safe mode, it means that the problem is in one of the apps you installed, and remove the newly installed programs one by one until the problem disappears.
⚠️ Warning: Avoid installing memory cleaners and accelerators from the Play Market Store. On modern Android versions, they often do more harm than help, creating additional workload and conflicting with the system optimizer. MIUI.
Hardware problems and overheating of the device
If the Redmi smartphone has been subjected to falls or moisture, the plumes may have left or the contacts on the board are disrupted, and in such cases, departures may be accompanied by other symptoms: a lost sound, unstable Wi-Fi or a sensor.
Overheating is another enemy of stability: When critical temperatures are reached, the processor resets frequencies (trottling), and if this is not enough, the system crashes heavy applications or reboots, which often happens when using the navigator while charging or when playing long games in hot weather.
Battery wear can also affect electronics, so if the battery can't deliver the required current under load, the voltage drops, which is perceived by the system as instability, and in such cases, even simple actions can cause failures.
💡
If the flights started after a phone crash or water hit, software methods may not help, and in this case, a diagnosis is needed at a service center to check the motherboard.
Radical methods: Resetting and flashing
If none of the above methods worked, the last resort is a complete factory reset, which will delete all user data, photos, contacts and apps, returning the phone to the “out of the box” state.
Resets can be done via the settings menu: Settings → About Phone → Settings Reset → Erase all data. A deeper reset is done via Recovery Mode (clamping the volume button up and the power button when the phone is off). Once reset, the problem should disappear unless it is caused by physical damage.
In the most difficult cases, even after a reset, errors can occur, it may require a flashing of the device. This is the process of completely replacing the phone's software. For Xiaomi, there is a tool called the Mi Flash Tool that allows you to install clean official firmware. However, this requires certain skills and a computer.
