Why Xiaomi smartphone throws out of applications: a full analysis of the causes and solutions

You launch a game, a social network, or a messenger on Xiaomi, and after a few seconds, bam!, the app suddenly shuts down. Sometimes it's an error, sometimes it just returns to the desktop. This problem is familiar to many owners of smartphones Redmi, Poco and Mi, and it can manifest itself as new models (Xiaomi 14, Redmi Note 13 Pro).+), and on devices from 2020 to 2022 (Redmi Note 10, Poco) X3 Pro? whether it is "raw" firmware, memory shortage or hardware problems?

In this article, we'll look at all the possible reasons Xiaomi is dropping out of apps, from basic to rare. You'll learn how to diagnose a problem, which settings to check first, and when to contact the service. MIUI 14/15 Android 13/14, which work with most of the brand’s devices.

1. Optimization MIUI: Why does the system kill applications?

The most common reason for departures is aggressive optimization of energy consumption in the shell. MIUI. By default, the system limits the background activity of applications to save battery power, but sometimes this “saving” leads to programs closing even in the foreground.

How does it work? MIUI There's Memory Management, which compulsively releases RAM, killing processes. If your application consumes a lot of resources (like games or video editors), the system can decide that it's frozen and shut it down.

• 🔋 Battery priority: MIUI By default, it prefers energy savings over productivity.
• 📱 Weak models: On Redmi 9A POCO C31 2–3 GB of RAM Departures occur more often due to lack of memory.
• 🔄 Autoclean: Clear Memory (in the notification curtain) may work by accident.

To check if optimization is to blame, open Settings → Annexes → Permits → Auto-run and see if it's on for a problem app. If it's not, that's the first reason for the crashes.

Lack of RAM (RAM)

If you have a smartphone with 4GB of RAM or less, there is a good chance that apps are closing due to memory overload. MIUI Cache is actively used, and when there is less than 500-700 MB of free memory, the system begins to force the background processes to close – sometimes together with active ones.

How do you check? Open the settings. → The phone. → Memory and see the RAM schedule. If it's free, less than 1 GB, it's critical. You can also use applications like Developer Options (turned on through Settings). → The phone. → Version. MIUI — Tap 7 times), where detailed statistics are displayed in the Memory section.

Decisions:

• 🧹 Clear the cache: In Settings → Annexes → [Select the application] → Warehouse → Clear the cache.
• 🔄 Close background apps: In the menu of recent apps swipe up unnecessary.
• 📱 Use the “Lite” version: For example, Facebook Lite instead of the main client.

💡

If you have 4 GB of RAM, try disabling the system animation in the Settings for developers (window animation scale, Transition animation scale settings set to the 0.5x). This will reduce the memory burden.

3. Conflicts with firmware or updates

After updating MIUI beforehand 14.0.5–15.1.2 Many users have experienced massive dropouts of applications due to a bug in the core of the system, especially devices on Qualcomm Snapdragon chips. 7xx/8xx (for example, Poco F4, Xiaomi 12T). In some cases, the problem was solved by rolling back on the previous version of the firmware.

How do you know if the update is to blame?

• 📅 The flights started immediately after the update.
• 🔄 The problem is manifested in all applications, not in one.
• 📱 Error logs (can be viewed via App Info or Adb logcat) include a mention of libc or surfaceflinger.

Decisions:

1. Reverse to old firmware: Download the previous version MIUI From the official website and go through Fastboot or Recovery.
2. Cleaning up the System Update application data: Go to Settings → Annexes → Updating the system → Warehouse → Clear the data.
3. Resetting: If rollback is not possible, try Settings → Additionally. → Resetting settings (without deleting data).

4.Store problems: corrupted files or lack of space

If the phone has less than 1-2 GB of free space, Android starts to work unstable: applications can fly out, slow down or not open at all, and the cause can also be corrupted cache files or application data.

How to diagnose:

1. Open the Settings. → Storage and check the vacant space.
2. If less than 10% of the total volume, this is a critical value.
3. Run the built-in cleaning utility: Settings → The phone. → Memory. → Clean up.

Decisions:

• 🗑️ Delete unnecessary files: Photos, videos, APK, load.
• 🔄 Transfer the data to SD-Map: In Settings → Warehouse → Data portability.
• 🛠️ Clear the cache of system applications: Through Developer Options or adb shell pm clear --user 0 [package_name].

If the problem persists after cleaning, check the integrity of the file system through the adb shell fsck or reset the phone to factory settings (with data saved to the PC).

5. Conflicts with Magisk, root rights or custom firmware

If you're installing Magisk, TWRP or custom firmware (e.g. Pixel Experience, LineageOS), application departures may be associated with:

• 🔓 Incorrectly installed root: Some applications (banking, games) block work on rooted devices.
• 📦 Magisk Module Conflict: For example, Xposed Framework or LSposed may break compatibility.
• 🔄 Unstable custom firmware: especially if it is assembled under a different model.

How to check:

1. Run Magisk Manager and check the status of the root.
2. Disable all modules in Magisk and restart your phone.
3. If the flights have stopped, turn on modules one at a time to find the culprit.

Decisions:

• 🔄 Update Magisk: The latest stable version — v26.4 (2026).
• 🚫 Turn off the root for problem apps: Magisk has a DenyList option.
• 📱 Return to stock firmware: If the custom version is glitzy.

⚠️ Attention: Some banking applications (Sberbank, Tinkoff) and games (PUBG Mobile, Genshin Impact) actively block rooted devices.If you use MagiskHide, make sure it's properly configured for those apps.

Hardware problems: overheating, battery wear, damage

If software solutions did not help, the reason may lie in the hardware:

• 🔥 Overheating: At a processor temperature above 60–65°C MIUI Forcedly closes resource-intensive applications.
• 🔋 Battery wear: If battery capacity falls below 70%, the phone may not get enough power, leading to failures.
• 🛠️ Memory damage: Physical defects of the eMMC or UFS-The storage device causes read/write errors.

How to diagnose:

• Install. CPU Monitor AIDA64 temperature-check.
• Check battery wear via ##4636## (test menu) or AccuBattery.
• If the phone drops or restarts when a particular app (like a camera) is launched, it could indicate that the module is damaged.

Decisions:

• 🔥 When overheating: Remove the case, avoid direct sunlight, use a cooling stand.
• 🔋 Replace the battery (cost for Xiaomi – from 1,500 to 3,000) ₽).
• 🛠️ If memory damage occurs: Contact a diagnostic service center.

💡

If the phone turns off or reboots when loaded (games, video shooting), with a 90% probability to blame the worn battery or overheating of the processor.

7.Problems with Google Play Services and Xiaomi Services

Many departures are associated with disruptions to background services, such as:

• 🤖 Google Play Services: Responsible for most apps.
• 📱 MIUI Optimization: System process that manages performance.
• 🔒 Security App: Antivirus and protection from Xiaomi, which can block applications.

How to check:

1. Open Settings → Applications → Application Management.
2. Find Google Play Services and check if there are any errors.
3. Run Settings. → Passwords & security → Scan for virus testing.

Decisions:

• 🔄 Update Google Play Services: Play Market or APKMirror.
• 🗑️ Clear the data: for Google Play Services and MIUI Optimization.
• 🚫 Disable unnecessary services: For example, Mi Video or Mi Browser, if you are not using it.

⚠️ Warning: If the apps stop updating after Google Play Services cleans up, restart your phone and wait for automatic sync (may take up to 10 minutes).

8. Viruses, malware and fake apps

One of the most insidious reasons for flights is viruses or Trojans that:

• 🕵️ Masquerading as system processes.
• 📱 Intercepting application management.
• 🔋 Increase the load on the processor, causing the forced closure of programs.

How to detect:

• Check the list of running processes in Developer Options (Running services).
• Use antiviruses: Malwarebytes, Dr.Web Light.
• See if there are any unknown notifications or advertisements.

Decisions:

1. Remove suspicious applications: Especially those installed from APK.
2. Reset your phone to factory settings: If the virus has built into the system.
3. Install a reliable antivirus: for example, Kaspersky Mobile.

Most often, viruses get to the phone through:

• 📎 Investments in SMS/messenger.
• 🔗 Links to “hacked” versions of games/programs.
• 📥 Files from unverified sources (Torrent, Telegram channels).
