Why Xiaomi is crashing apps: System causes and ways to fix

You run your favorite game or messenger on a Xiaomi smartphone, but after a few seconds the app suddenly shuts down? This problem is familiar to many owners of devices based on MIUI — from budget Redmi to flagship Xiaomi 13/14. The reasons can lie in both software failures and hardware limitations. In this article, we will analyze the 10 most common causes of application departures on Xiaomi and give specific recommendations for their elimination, from cleaning the cache to flashing.

It's important to understand that apps rarely come out randomly, and they often signal deep problems like overloaded memory, conflicts with Android and MIUI versions, or even incipient wear on the drive, and we're not going to just stick to the formulaic tips like "reboot your phone" -- instead, we're going to offer a systematic approach with diagnostics and targeted solutions.

This article is relevant for all modern models Xiaomi, Redmi and POCO based on MIUI 12-14 and Android 11-14. If your device is older than 2019, pay special attention to the sections on memory wear and firmware incompatibility.

1. Lack of RAM (RAM)

Xiaomi is known for aggressive RAM optimization, but sometimes it fails. If you have a model with 4-6 GB of RAM (like the Redmi Note 10 or the POCO X3 Pro), applications can crash due to lack of resources — especially when multitasking.

How do you check? Open Settings → About Phone → Memory and see the RAM schedule. If less than 20% is free, the system begins to force the background processes to close. Solutions:

• 🔄 Turn off the autoclean. RAM: Go to Settings. → Special facilities → Clean up the memory and deactivate the option.
• 🚫 Limit the background processes: in Settings → Annexes → Application management → Auto Start Disable Autoboot for Unnecessary Programs.
• ⚡ Use the performance mode: in Settings → Battery → Select “High Performance” mode (reduces work time but reduces departures).

For models with 8+ GB of RAM (such as Xiaomi 12T or Black Shark 5), the problem may lie in the memory leaks of specific applications, in which case only restarting the problematic software or a full restart of the phone will help.

2.Crowded storage (ROM)

When internal memory is packed (less than 10% of the available space), the system starts to crash: applications can not save temporary files, the cache is not updated, and MIUI forcibly closes processes, especially critical for budget models with 32-64 GB of memory.

Check the space available in Settings → Storage. If it is less than 5 GB, follow the following steps:

• 🗑️ Clear the app cache: Settings → Annexes → Select the application → Warehouse → Clear the cache.
• 📁 Delete unnecessary files: Use the built-in Cleanup or Files app from Google.
• 🔄 Transfer the data to SD-map (if supported): Settings → Warehouse → Data portability.
• ☁️ Activate Cloud Storage: Mi Cloud or Google Drive to Backup Photos and Videos.

💡

If your memory is filling up quickly after cleaning up, check your Android/data folder – some games (like Genshin Impact or Call of Duty Mobile) can take up tens of gigabytes.

For models with UFS 2.1/2.2 (e.g. Redmi Note 11 Pro+), not only is the amount of space available critical, but also data fragmentation. If the problem persists after cleaning, try to reset completely (see section 7).

3. Conflicts of MIUI and Android versions

Xiaomi regularly releases MIUI updates, but not all of them are stable. If the flights started after the update, the new version of the firmware is to blame.

• 🆕 Transition on MIUI 13/14 older version.
• 🤖 Android updates (for example, 11 to 12).
• 📱 Installation of beta versions of firmware.

How to check compatibility? Compare your firmware version to official data on MIUI Downloads. If your version is labeled "Stable" but the crashes continue, try:

1. Reverse to the previous stable version via Fastboot (instructions in section 7).
2. Clear the data of the Settings application → Applications → Settings (app) → Storage → Clear the data.
3. Disable MIUI Optimization for a Specific Application: Settings → Applications → Select Application → Battery → No Limits

If you use custom firmware (like Pixel Experience or LineageOS), departures may be due to incorrect build, in which case, check the XDA Developers forums for bugs for your model.

4. Errors in these applications

Damaged cache or application data files are one of the most common causes of departures, and this can happen after:

• ⚡ Unexpected power outage during application operation.
• 📱 Interrupted update of the application through the Play Market.
• 🔄 Conflict after memory cleaning by third-party utilities (e.g., CCleaner).

The diagnostics are simple: if one particular app (like Instagram or WhatsApp) crashes and the rest work fine, the problem is precisely in its data.

Clear the app's cache

Clear the application data

Reinstall the application

Check the application permissions-->

For system applications (e.g. com.miui.gallery or com.android.contacts), data cleaning can reset, and if the application stops running at all after cleaning the data, you will need to flash it through Fastboot.

If the crashes occur in games (such as PUBG Mobile or Free Fire), the problem may be:

• 🎮 Incompatibility with the version OpenGL/Vulkan.
• 🔧 Lack of access rights to storage or microphone.
• 📡 Poor Internet connection (for online gaming).

5. Permit and security issues

MIUI is known for its strict permissions policy, which sometimes blocks legitimate applications.

• 📸 Camera (TikTok, Snapchat),
• 📍 Geolocations (Google Maps, Uber),
• 🎤 Microphone (WhatsApp, Discord),

Check permission settings: Settings → Apps → Select the app → Permissions.

MIUI also has a hidden feature called Battery Optimization, which can force applications to close to turn it off.

1. Go to Settings → Battery → Battery Optimization.
2. Click on the three dots in the top right corner and select All Apps.
3. Find the problem app and select No Limits.

💡

Even if you have given all permissions manually, some applications (such as banking) may conflict with the Personal Data Protection feature in MIUI. Try temporarily disabling it in Settings → Privacy → Privacy → Privacy Protection of Personal Data.

For models with IR-locking (infrared sensor, for example, in Xiaomi Mi 11) can work protection against unauthorized access. If the application flies when unlocked in the face, turn off this feature in Settings → Lock screen → Unlock face.

Processor overheating

Xiaomi (especially models with Snapdragon 8 Gen 1/2 processors) are prone to overheating, which leads to trottling, a forced performance decline, and if the temperature exceeds 45°C, the system begins to close resource-intensive applications.

How to check:

1. Install the AIDA64 or CPU Monitor app.
2. Run the problem app and monitor the temperature.
3. If the temperature is above 50°C, it is kriticheskij peregrev.

Decisions:

• ❄️ Remove the cover - it can block the heat sink.
• 🔄 Close the background processes through Settings → Annexes → Launched.
• 📉 Reduce screen resolution in Settings → Screen. → Screen resolution.
• 🔋 Turn off fast charging during play (in Settings) → Battery → Fast charging).

💡

For gamers (Black Shark or POCO F4 GT), use the built-in Game Turbo, which optimizes cooling and resource allocation.

If overheating occurs even in simple apps (such as Chrome or Telegram), it could indicate:

• 🔋 Battery wear (check in Settings) → Battery → Battery status).
• 🛠️ Thermopaste problems (relevant for devices older than 2 years).

7. Resetting and flashing

If none of the previous methods worked, then radical measures remain: factory reset or flashing.

• 📱 Departures occur in all applications.
• 🔄 The system began to slow down even in the menu.
• 📵 Artifacts appear on screen or random reboots.

Reset to factory settings (Hard Reset):

1. Make a backup of the data through Settings → Additional → Backup and Reset.
2. Go to Settings → About the phone → Reset settings.
3. Choose to erase all data and confirm.

Fastboot Flashing (for experienced users):

1. Download the official firmware for your model from the MIUI Downloads website.
2. Install the Mi Flash Tool on your PC.
3. Transfer the phone to Fastboot mode (clip Power + Volume down).
4. Connect to the PC and follow the instructions of the program.

For models with an unlocked bootloader, you can try custom firmware like Pixel Experience or LineageOS, but this voids the warranty and can lead to additional problems.

8. Hardware malfunctions

If the software methods did not help, the reason may be iron:

To diagnose hardware problems:

1. Check your phone for physical damage (cracks, bloated battery).
2. Run the hardware test via Mi Check (built-in app) or AIDA64.
3. If the phone is warranty – contact the service center Xiaomi.

💡

If your Xiaomi fell from a height or came into contact with water, even if everything looks normal, microcracks on the board can manifest after months in the form of accidental drop-offs of applications.
