Why Xiaomi spontaneously change wallpaper: all the reasons and solutions

Have you noticed that on your Xiaomi smartphone, desktop wallpaper changes without you? This is a common problem faced by users of devices based on MIUI, Xiaomi's proprietary shell. In some cases, the background images change due to system functions that can be disabled, and sometimes software errors or third-party applications are the cause.

In this article, we’ll take a closer look at all the possible reasons why Xiaomi wallpaper changes automatically, from standard features like Theme and Lock Screen to hidden settings and firmware bugs, and you’ll find step-by-step instructions on how to regain control of your device’s appearance and capture your favorite background. If you’re tired of unexpected changes on the home screen, this guide will help you figure out the problem and fix it.

1. System function "Dynamic Wallpaper" in MIUI

The most obvious reason for the change of wallpaper on Xiaomi is the built-in Dynamic Wallpapers feature, which automatically adjusts the background to the time of day, the weather, or even your activity, for example, in the morning you can see the dawn, and in the evening you can see the sunset, a feature that is present in most modern versions of MIUI (starting with MIUI 12).

To check if this option is included:

1. Go to Settings → Wallpaper.
2. Select Dynamic Wallpaper or Live Wallpaper.
3. Check if the automatic change option is active.

If so, turn it off by selecting a static background, and note that some dynamic wallpapers (like Earth or Mars) can change even without explicit customization, because they are embedded in their logic.

2. Automatic change through the "Themes" app

Themes is another culprit in unexpected wallpaper changes, and not only does it offer new themes, it can automatically apply elements of them, including background images, if you have previously agreed to recommendations, especially for users who have downloaded themes from the official Xiaomi store.

How it works:

• 🔄 The app analyzes your preferences and suggests “recommended” themes.
• 📲 If you click Apply on one of the themes, the system may continue to update the wallpaper within that theme.
• 🔗 Some themes are tied to seasons or holidays (e.g. New Year's or Summer Wallpapers).

To disable automatic application:

1. Open the Topic app.
2. Go to Profile → Settings (cog icon).
3. Turn off Auto Update Themes and Recommendations on the home screen.

💡

If you want to save the current wallpaper but are afraid they will reset after the theme update, take a screenshot of the screen and set it as a background manually through the gallery.

3. firmware errors and MIUI bugs

Sometimes the wallpaper changes because of software failures in the firmware, which is especially true for:

• 📱 Devices with beta versions MIUI (for example, MIUI 14 Beta).
• 🔄 Phones after recent air update (OTA).
• 🛠️ Devices with custom firmware (for example, Xiaomi.eu or Pixel Experience).

Typical symptoms of the bug:

• Wallpaper is reset to standard after rebooting.
• The background changes to a random image from the gallery.
• The lock screen and home screen have different wallpapers, although you have set the same ones.

Decisions:

1. Reset the wallpaper settings: go to Settings → Wallpaper → Reset to standard.
2. Clear the Themes app cache**: Settings → Apps → Application Management → Topics → Storage → Clear the cache
3. Reverse to the stable version of MIUI if you use beta firmware.

4.The Impact of Lock Screen and Always On Display

On many Xiaomi models (e.g. Redmi Note 12 Pro)+ Xiaomi 13T) Lock screen and always on display (AOD) It can affect the wallpaper on the main screen. MIUI These two backgrounds are sometimes synchronized, and settings are AOD priority.

How it manifests itself:

• 🔒 You set the wallpaper on the main screen, but after blocking it, it is reset.
• 🌙 During the dark, the background automatically becomes dark (Adaptive Lock Screen function).
• ⚡ When activated AOD The wallpaper can be “adjusted” to the display style of time.

To break that bond:

1. Go to Settings → Lock screen.
2. Disable options: Sync lock screen wallpaper and home screen Adaptive lock screen Automatic change of AOD wallpaper (if any)

Set separate wallpapers for the lock screen and the main screen.

💡

If you use Always On Display, turn off automatic background changes in its settings – this is a common cause of conflicts with the wallpaper of the main screen.

5. Third-party applications and viruses

Not all wallpaper changes are caused by MIUI, and third-party apps are sometimes to blame, especially:

• 🎨 Lonchers (for example, Nova Launcher, POCO Launcher).
• 🖼️ Wallpaper applications (e.g. Zedge, WallpapersCraft).
• 🦠 Viruses or Adver apps that change the background to display ads.

How to check:

1. Go to Settings → Applications → Application Management.
2. Sort the list by installation date and check for unfamiliar programs.
3. Note apps with the rights to Change system settings or Overlay over other applications.

If you suspect a virus:

• Install an antivirus (such as Dr.Web or Malwarebytes).
• Check your phone in Safe Mode (press the power button → Safe Mode) If it doesn't change, it's third-party software.

6. Reset settings after system update

After major MIUI updates (e.g., from MIUI 13 to MIUI 14), the system may reset some settings, including wallpaper.

• 🔄 Change the theme storage structure (backgrounds are saved in a different format).
• 📁 Cleaning the cache of the “Themes” application during the update.
• 🔧 Conflicts between old and new settings.

What to do:

1. After updating manually install the wallpaper again.
2. Check if the settings in the Topic app have reset.
3. If the problem repeats, reset the theme settings: Settings → Annexes → Topics → Warehouse → Clear the data ⚠️ Warning: This will remove all downloaded themes and return the standard design.

If the reset didn't work, it might have been an error in the update, and in this case, it's worth:

• Reinstall the update via Settings → About Phone → System Update.
• Make a full reset (but save the data beforehand!).

7. Features of specific Xiaomi models
