Error “In the application again there was an error” on Xiaomi: causes and solutions

You saw a message on Xiaomi’s screen saying, “There’s been an error again in the app” — and now you don’t know what to do? — a problem that many owners of Redmi, POCO or Mi smartphones are familiar with, especially after updating MIUI or installing new apps. The error can appear in any program from the Google Play Store to system utilities, blocking their operation or causing sudden closures.

90% of the time, it's not because of a fatal phone crash, but because of software conflicts, overloaded cache or incorrect settings, and we've compiled all the working solutions, from simple (reboot) to radical (reset to factory settings), and we've also explained why the bug comes back even after the fix, and if your Xiaomi says it when you open a particular app or constantly, read on.

Why there is an error “in the application there was an error on Xiaomi”

The message “Unfortunate, [app name] has stopped” is the standard Android response to a malfunction, and on Xiaomi smartphones, the problem is most often due to the following factors:

• 📱 Conflict of versions MIUI and applications: after updating the firmware, some programs become incompatible with the new system.
• 🗑️ Cache overflow: Temporary application files take up too much space and cause crashes.
• 🔄 Incorrect update: interrupted installation of the update MIUI or apps from the Play Store.
• 🛠️ Damaged system files: often after a failed rooting or firmware modification.
• 📲 Limitations MIUI: Aggressive battery or background optimization from Xiaomi could block apps.

Redmi Note 10/11, POCO X3/X4 and Mi 11 models on MIUI 13/14 are particularly vulnerable to this error, because their firmware often contains memory management bugs. If the error appears in only one application (for example, WhatsApp or Google Chrome), the problem is more likely in itself. If the failure occurs in all programs, the system is to blame.

Method 1: Rebooting your smartphone – why it works

It sounds trivial, but a forced reboot eliminates the bug 30 percent of the time, because MIUI (like any Android) keeps apps in RAM even after they're closed, and if it freezes in the background, the system won't be able to restart them correctly, hence the error message.

How to Reboot Xiaomi correctly:

1. Press the power button for 5-7 seconds.
2. In the menu that appears, select Reboot (not Shut down!).
3. Wait for the full shutdown and automatic switching on (usually takes 20-30 seconds).

If the error is gone after the reboot, but Later returns, the problem is deeper. On models with a Snapdragon processor (for example, POCO F3), rebooting helps more often than on smartphones with MediaTek (Redmi 9A), due to the peculiarities of memory management.

💡

If the power button does not respond, press the Power + Volume up at the same time for 10-15 seconds - this will force the phone to restart even when hanging.

Method 2: Clearing the cache and data of the problem application

App caches are temporary files that speed up their work, but over time they accumulate, corrupt, or conflict with the new version of the program. Clearing the cache will not delete your data (photos, messages, settings), but will reset all temporary files.

Instructions:

1. Open Settings → Applications → Application Management.
2. Find a problem app (such as Google Play Store or Gallery) in the list.
3. Slap it on and select the Warehouse.
4. Click Clear the cache, then Clear the data (if the error persists).

If an error appears in a system application (such as Settings or Phone), clearing the data may reset it to factory settings. For Google Play Services, this is safe, but for Messages or Contacts, it is better to back up.

Synchronize your contacts with Google

Save important files from the application

Remember the username / password (if the application requires authorization)

Restart the phone after cleaning-->

Method 3: Update or reinstall the application

If the bug only occurs in one application, check its relevance.Outdated versions of programs often conflict with the new MIUI.

• 📥 Through Play Store: Open Play Store. Find a problem app. If you have an Update button, click it.
• 🔄 Through APK-File (if update is not available): Download the current version APK from an official website (e.g. APKMirror) Install the file by allowing installation from unknown sources (Settings) → Annexes → Special access → Installation of unknown applications).

If the update didn’t work, uninstall the app completely and reinstall it. For system applications (like Camera or Music), deletion can be blocked – in this case, only a firmware rollback or a setting reset will help.

Method 4: Verifying the resolution and optimization of the battery

MIUI aggressively optimizes applications in the background, which can lead to their collapse. If an error appears when the application goes into the background (for example, in Telegram or Viber), check the battery settings:

1. Open Settings → Applications → Application Management.
2. Select the problem app.
3. Tap Permits and make sure all necessary rights are included (e.g. access to storage or camera).
4. Go back and select Battery Limits.
5. Set up a No Limits mode.

Also disable auto-clean memory in Settings → Special Features → Memory Cleanup. This feature forcibly closes background applications, which can cause errors when they are reopened.

💡

On models with MIUI 14 and later, battery optimization works differently – instead of “No Limits”, select “Intelligent Control” and add the application to exceptions.

Method 5: Resetting settings to factory (last chance)

If none of these things work, you have to reset the phone back to factory. This will delete all the data, so be sure to back up through Settings → About Phone → Backup or Mi Cloud.

How to reset your settings:

1. Open Settings → About the phone → Reset settings.
2. Choose to erase all data.
3. Enter a password (if required) and confirm the action.
4. Wait for the process to be completed (it will take 5-10 minutes).

After the reset, the phone will turn on as new. Don't restore the data from the backup right away -- first check if the error appears on the "clean" system. If not, the problem was a conflict of settings or files.

⚠️ Note: On some models (Redmi Note 8 Pro, POCO F1) After the reset, you may need to re-activate the bootloader. If the phone does not turn on or asks you to enter your Mi Account, use the official unlock tool.

Method 6: Fastboot Flashing (for experienced ones)

If the error appears in all applications or after a reset, the problem may be the damaged firmware, in which case the firmware reflash through Fastboot, a method that completely reinstalls MIUI, fixing system errors, will help.

You'll need:

• 🖥️ Computer with installed Xiaomi drivers and Mi Flash Tool.
• 📱 Unlocked bootloader (if the phone doesn't turn on, use the official tool).
• 🔗 Firmware for your model (download from the official website).

Step-by-step:

1. Turn off the phone and press Power + Volume down to log into the Fastboot.
2. Connect your smartphone to your PC.
3. Start the Mi Flash Tool, select the downloaded firmware.
4. Press Refresh, then Flash (select Clean all option).
5. Wait until the end (10-15 minutes).

⚠️ Attention: Continuous power is critical! If the process is interrupted, the phone can turn into a brick. Use the original cable and charge the battery at least 50% before the firmware.

After flashing the phone will turn on with a clean MIUI. If the error remains - a problem in the hardware (for example, damaged memory), and requires repair.
