Why Xiaomi is constantly resetting desktop wallpaper – and how to fix it

You installed beautiful wallpaper on your Xiaomi, but after a few hours (or after the reboot) they suddenly changed to standard? This problem is familiar to many owners of smartphones brand — from budget Redmi Note to flagship Xiaomi 13. Wallpaper reset can occur after the MIUI update, and for no apparent reason. In this article, we will discuss the 5 main reasons for this behavior of the system, and give step-by-step instructions for their elimination.

It's important to understand that the problem isn't always hardware-related, and 80 percent of the time it's power saving settings, application conflicts, or cache errors, and we analyzed user feedback on the 4PDA and Mi Community forums, and we tested the solutions on devices with MIUI 12-14, and the results are in this guide.

1. Battery optimization and background activity

The most common reason for wallpaper resets is aggressive battery optimization in MIUI. The system automatically closes background processes, including the Wallpaper app, which leads to loss of user settings, especially on devices with Ultra-Economic or Adaptive Battery mode on.

To check if optimization is to blame:

• 🔋 Open the Settings. → Battery and productivity → Battery management.
• 🔍 Find the Wallpaper app (or Wallpaper on English firmware) in the list).
• ⚡ If there is a sign next to it Restricted, click on the app and select Without Limits.

Critical detail: On some models (e.g. Redmi 10 and POCO X3 Pro), the Wallpaper app is hidden in the list. To find it, turn on the display of system processes in the upper right corner of the screen.

2. Wallpaper app cache errors

The Wallpaper cache stores temporary data about the selected background, its scale and positioning. If the cache is damaged (for example, after an application is forced to close or the system crashes), MIUI can “forget” your settings and return standard wallpaper, this problem most often manifests itself after updating the firmware or cleaning the memory through Security.

How to clean the cache correctly:

1. Go to Settings → Applications → Application Management.
2. Find Wallpaper (or Wallpaper) and open its settings.
3. Press Warehouse. → Clear the cache.
4. Don't clean the data! It will reset all the user wallpaper.

💡

If the wallpaper is still reset after cleaning the cache, try reinstalling it: upload the image again from the gallery, rather than choosing from the story.

On some firmware (e.g. MIUI 13 for the global version), the cache is automatically cleared at low memory levels.

• 📱 Turn off the Auto Clean option in Settings → Warehouse.
• 🗑️ Regularly delete unnecessary files manually through Files).

3. Conflicts with launchers and themes

If you use a side launcher (like Nova Launcher, Lawnchair) or change MIUI themes frequently, it can cause wallpaper resets.The fact is that launchers have their own mechanisms for storing background images, and the themes sometimes overwrite system settings.

How to check:

• 🎨 Install a standard launcher MIUI: Go to Settings. → Home screen and select Standard.
• 🖼️ If the wallpaper stopped dropping, the problem is in the third-party launcher. Update it or reset the settings.
• 🎭 For themes: Go to Topics, reset the current theme to standard and check the behavior of the wallpaper.

On POCO and Black Shark devices, the proprietary launcher POCO Launcher creates additional complexity, which is optimized for game scenarios and can reset wallpaper when activated by Game Turbo mode.

⚠️ Note: If you play resource-intensive games (such as Genshin Impact or Call of Duty Mobile), turn off the option of Background Optimization in the settings. POCO Launcher.This will prevent automatic wallpaper resetting.

4. Mistakes after MIUI update

MIUI updates often bring not only new features but also bugs. For example, after the release of MIUI 14, many users of Xiaomi 12T and Redmi K50 complained about spontaneous wallpaper reset, the reason being a bug in the mechanism of synchronizing settings with the Mi Account cloud.

How to fix it:

1. Check the firmware version in Settings → About Phone → MIUI version.
2. If the version is fresh (for example, 14.0.5), wait for the patch or roll back to stable build through Settings → System Update → Three Points → Select the service pack.
3. Turn off the wallpaper sync with the cloud: Settings → Mi Account → Synchronization → Wallpaper (uncheck the box).

If the problem appears immediately after the update, try resetting the app settings:

adb shell pm clear com.miui.home

This command will reset the home screen settings, but will not delete user data.

5. Hardware problems and memory damage

In rare cases, wallpaper reset may be associated with damage to internal memory or a malfunction of the storage module, not only with a failure of wallpaper, but also with other symptoms:

• 📱 Self-involved reboots.
• 🗃️ Disappearance of files from the gallery.
• ⚡ Fast battery discharge (due to constant overwriting of damaged sectors).

How to diagnose:

1. Run the built-in memory check: Settings → Memory → Three dots → Check.
2. Use the AIDA64 app (Site of Storage → Memory Test).
3. If errors are found, make a backup copy and contact the service center.

⚠️ Attention: On devices with UFS 2.2/3.1 (for example, Xiaomi 11T Pro, Black Shark 5) Memory damage can lead to complete data loss.Do not ignore test errors!

Check Memory Through Settings

Run the test in AIDA64

View the error logs in Engineer Mode (#4636###)

Reset the settings to factory (if errors are repeated)

Contact the service in case of critical failures

6. Viruses and malware

An unlikely but possible scenario is the action of viruses or adware that change system settings, such as the Android.Triada Trojan family, which can modify MIUI configuration files, including wallpaper settings.

Signs of infection:

• 🛡️ Appearance of unfamiliar apps on the menu.
• 📴 Advertising in the status bar or on the lock screen.
• 🔄 Independent installation of wallpaper with advertising.

How to check and clean:

1. Download Malwarebytes or Dr.Web Light and perform a full scan.
2. Remove suspicious apps through Settings → Apps.
3. If the virus is deeply embedded, reset to factory settings (Settings → About Phone → Reset settings).

💡

Viruses rarely target wallpaper, but if the reset is accompanied by advertising or strange behavior of the system - this is an occasion to check the device for malware.
