The situation of resetting wallpaper on the lock screen or desktop is one of the most annoying problems for owners of Xiaomi, Redmi and Poco smartphones.The user sets up a beautiful image, but after a few hours or after the device is rebooted, the standard screensaver or brand logo returns.It is not just aesthetic discomfort, but a signal of conflict in the software of the MIUI or HyperOS shell.
Most of the time, the problem is not hardware, but system applications that are responsible for visualization, and aggressive battery optimization can force gallery processes to close, or cause a reset of the design settings, and understanding the nature of this failure is the first step to fix it without losing personal data.
In this article, we will take a closer look at all the possible reasons why wallpapers fly off on your device, and provide step-by-step instructions for solving this problem. We will look at the theme settings, system services and hidden parameters that not all users know about.
Thematic conflict and the work of the “Themes” app
The most common reason why wallpapers fly is the conflict between the installed theme and system settings. In the MIUI shell, the Theme app takes precedence over the standard gallery. If you downloaded the theme from a third-party source or even from an official store, but it contains errors in the code, the system can automatically roll back changes, returning a default image.
Often users forget that activating a new theme resets previous customizations. If you installed an image through a gallery and then the backgrounds were updated, your wallpaper will be replaced. To avoid this, you need to check if the third-party visual style is activated at the moment.
In some cases, a complete reset of the app’s theme settings helps. This won’t remove your downloaded themes, but will return the software components to their original state. To do this, go to Settings → Apps → All Apps, find Themes and select Clean. After that, try installing the wallpaper again.
💡
Before installing a new theme, always check its ranking and compatibility with your Android version to avoid display conflicts.
It is important to note that some lightweight versions of themes may not support dynamic wallpaper or high-resolution images, leading to their automatic replacement with lighter standard options.
The Impact of Wallpaper Carousel and MSA Services
Xiaomi smartphone owners often encounter the Wallpaper Carousel feature, which automatically changes images on the lock screen.If this feature is enabled, it can overlap your static wallpaper, creating the illusion that they have "tracked."MSA (MIUI System Ads) service and related components can impose content that the user did not choose.
To check if the carousel is causing the problem, you need to go to the lock screen settings. The path usually looks like this: Settings → Always on screen and lock screen. Here you need to find the wallpaper carousel and make sure that the switch is off.
☑️ Checking the lock settings
Even if you didn't specifically turn this feature on, it could be activated after a major system update, in which case the wallpaper is reset precisely because the carousel service is prioritized over the user settings, and disabling this service will also have a positive effect on the autonomy of the device.
⚠️ Attention: Disabling system advertising services (MSA) may require confirmation of SMS, Do not close the confirmation window until you have the code.
Battery optimization and background work
The aggressive MIUI energy-saving system is known for its tight control of background processes. If the application through which the wallpaper was installed (such as Google Photos or the standard Gallery) was closed by the system to save charge, this can lead to the loss of the link to the image, resulting in a black background or a standard screensaver.
To prevent this, you need to configure exceptions for key applications. Go to Settings → Battery and Performance (or simply Battery). Find the Gallery or Themes app in the list and change the power saving mode to No Limits.
It's also worth checking the permissions for these apps. Make sure they have access to the device's memory and, in some cases, auto-start permission.Without these permissions, updating the wallpaper or saving it after a reboot may not be possible.
Sometimes the problem is solved only after the complete removal of updates to the system components responsible for the interface, but this is an extreme measure to resort to if simple settings did not help.
Problems with the storage and cache of the system
A crowded system cache or corrupted temporary files can cause an interface to function in an unstable way. When wallpaper flies, it often indicates that the system cannot read the image file correctly from memory, especially for devices with a full internal storage.
It is recommended to clean the cache through the Recovery menu. To do this, turn off the device and press the combination of the Volume up + Power buttons. In the menu that appears (using the volume buttons for navigation and the power button for selection), select Wipe Cache. This is secure and will not delete your personal data.
| Type of data | Impact on wallpaper | Recommended action |
|---|---|---|
| Cash app. | High (display errors) | Cleaning through settings |
| System cache | Medium (interface glitches) | Wipe Cache at Recovery |
| File.theme | Critical (thematic conflict) | Resetting the topic to standard |
| SD-map | High (if there's a photo there) | Integrity verification |
If the image is stored on SD-If you try to transfer it to the internal memory, if you read the external drive when you boot the system, you'll see that the wallpaper won't be used.
Hidden System Files of Themes
Synchronization with Mi Cloud and account
The Mi Cloud cloud sync feature can create setting conflicts. If another device linked to your account has other wallpaper installed, it can automatically sync and replace local settings on your current phone.
Check your sync settings in Settings → Mi Account → Mi Cloud. Make sure that the theme or screen settings are not synced if you want to keep the unique design for each device separate.
Also, sometimes a simple account reassignment helps: log out of your Mi Account and log in again. This will update the authorization tokens and can eliminate the errors that cause wallpaper to be reset when you try to download them from a cloud backup.
⚠️ Warning: Before logging out, make sure you remember the password, as without it, login after reset can be blocked by the Mi Cloud protection.
Specifics of Android 13, 14 and HyperOS
With the release of new versions of Android and the HyperOS shell, the configuration file storage structure has changed. In Android 13 and later, access to certain directories is limited, which can prevent older versions of the Theme apps from correctly recording the path to the image.
If you have recently updated and noticed a problem, try updating all system applications through the GetApps store or Google Play. MIUI/HyperOS System Framework.
💡
On new versions of Android, it is critical to use only regular wallpaper installation tools, as third-party launchers may not have the necessary permissions.
In some cases, the bug only appears on specific versions of firmware. Monitoring the developer forums will help you understand whether the problem is massive for your model, for example, Xiaomi 13 or Poco F5, and whether you should wait for a patch.
Radical measures: Resetting and reflashing
If none of the above methods worked and the wallpaper continues to fly, the system configuration files of the interface may be damaged, in which case the most effective solution would be a full reset (Wipe All Data).
Before performing this procedure, be sure to back up all important data.Reset will return the phone to factory status, eliminating any software conflicts that have accumulated during use.
Settings → About the phone → Reset settings → Erase all dataIn extreme cases, when even a reset does not help (which is extremely rare), you need to flash the device through the computer using the Mi Flash Tool utility.
⚠️ Warning: Flashing through the Mi Flash Tool with Clear All will completely remove all files from the device.
