There’s been a mistake on Xiaomi again – what to do?

Xiaomi smartphones are famous for stable operation, but even they are not immune to sudden crashes in applications. the message “In the application there was an error” or “the App stopped” can appear at any time – when opening the messenger, launching the game or working with system utilities. Most often the problem is solved in a few minutes, but many users are lost, not knowing where to start.

In this article, we will analyze all possible causes of errors in applications on Xiaomi, Redmi and other platforms. POCO, And we'll also give you step-by-step instructions for how to fix them, from basic reboots to deep diagnostics. MIUI, which help to restore the work of even “killed” applications without resetting to factory settings.

Why are there errors in Xiaomi apps?

Failures on Xiaomi smartphones are rarely accidental, and 90% of them are caused by system conflicts, version incompatibility or hardware limitations.

• 📱 Lack of RAM — MIUI aggressively closes the background processes, which can interrupt the operation of applications.
• 🗑️ Cache overflow – temporary application files accumulate and cause conflicts.
• 🔄 An outdated version MIUI or applications – bugs in firmware or software are often fixed in new updates.
• 🛠️ Conflict with optimization MIUI — Autostart or Battery can block background activity.
• 🦠 Viruses or damaged APK-Files – especially relevant for applications installed from third-party sources.

Interestingly, on newer models (Xiaomi 13/14, Redmi Note 12) errors are more likely to be associated with unoptimized games or Google background services, whereas on older devices (Redmi 4X, Mi A1) the problem usually lies in a lack of resources or outdated hardware.

First steps: What to do immediately after a mistake

If an app suddenly shuts down or sends out an error message, don't panic. Start with the simplest steps that solve the problem 70% of the time:

1. Close the app forcefully: Click on Recent apps (the button to the right of Home or a gesture up late), find the failed app and swipe it up. This will clear it from RAM.
2. Reboot your smartphone: Long press power button → Reboot. This step resets temporary system processes that could have caused conflict.
3. Check your Internet connection: Many errors (especially in Google Play, Mi App Store, or instant messengers) are due to unstable Wi-Fi or mobile network. Try switching to a different type of connection.

If after these manipulations the application again gives an error, move on to a deeper diagnosis.

On devices with MIUI 14+ You can use a quick reboot through the notification bar: swipe down twice, find the reboot icon (🔄) And you tap it. It saves time!

Cleaning the cache and application data

The most effective way to bring an app back to life is to reset its cache and data, which won't delete the app itself, but will clear temporary files that may have caused the crash.

Instructions:

1. Open Settings → Applications → Application Management.
2. Find the problem app in the list and tap it.
3. Select Warehouse. → Clear the cache.
4. If the error is repeated, go back and click Clear Data (⚠️ This will delete all settings and files of the application, including accounts!).

For system applications (e.g. Camera, Gallery, Settings), Clear Data can be blocked, in which case only resetting all settings (more on this below) will help.

Backup of important application data

Optimization and Auto Start Settings

The MIUI shell is known for its aggressive optimization, which sometimes interferes with the operation of applications. If an error occurs because the system forcibly closes the application, try to disable the restrictions:

fastboot flash vendor vendor.img




fastboot reboot

⚠️ Note: Fastboot flashing deletes all data, including files in internal memory, and there is a risk of a breeze if you interrupt the process!

You'll need to flash it back:

• 🖥️ Computer with Mi Flash Tool and drivers installed ADB/Fastboot.
• 📱 Unlocked bootloader (bootloader) on a smartphone.
• 📁 Official firmware for your model (download from Xiaomi website).
