When the background image of the lock screen or desktop suddenly changes on a Xiaomi smartphone, many users are puzzled, most often this is not due to a virus or a breakdown, but is the result of the company's built-in services, such as Wallpaper Carousel or Xiaomi Gallery. The system may perceive your actions as consent to automatic image change, or the settings were changed after updating the firmware.
Owners of devices based on MIUI shells and the new HyperOS often face intrusive behavior of a system that seeks to personalize the interface without explicitly requesting it, which may involve connecting a Mi Account account, installing themes from a formal store, or activating the Smart Wallpaper feature.
In this article, we’ll look at all the possible reasons why Xiaomi wallpapers change, and provide step-by-step instructions for disabling automatic replacement: you’ll learn how to manage system services, check third-party apps, and be able to capture your favorite image forever.
Carousel wallpaper: the main source of the problem
The most likely reason you have constantly changing images on your lock screen is because of the activated wallpaper carousel feature, which can be enabled by default on many Xiaomi models, especially when the device is first activated, and automatically uploads new images from the Internet every time you wake up the screen.
To stop this process, you have to go into the system settings, and the path may vary slightly depending on the version of the shell, but the logic remains the same, so you have to find the partition that controls the lock screen and turn off the switch that activates the new content.
⚠️ Warning: Once the wallpaper carousel is turned off, the current image may be saved but will no longer be updated. If you want to return a standard static image, you will need to manually select it from the gallery.
The disconnection process is as follows:
- 📱 Open the settings of your smartphone.
- 🔒 Go to Lock Screen (or Wallpaper and Personalization) → Lock screen).
- 🔄 Find the wallpaper carousel item and click on it.
- ❌ Turn the switch to the off position.
If the switch is active but the wallpaper is still changing, try clearing the app data. Go to Settings → Apps → All apps, find the Wallpaper Carousel and select Clean → Clear Everything. This will reset the cache and temporary files that can cause synchronization errors.
💡
If you can’t find the “Wallpaper Carousel” item in the settings, try searching by settings (the magnifier at the top of the screen) and entering the “Carousel” request.
Xiaomi Gallery settings and the car shifter
The second common reason is the built-in Gallery app from Xiaomi, which has its own wallpaper installer and can access the system settings of the screen. Often users accidentally activate the "Change Wallpaper Daily" or "Slides Show" feature by selecting a photo album.
Check the settings of the Gallery app itself. Open the app, go to the Recommendation tab, or click on the three dots (menu) in the corner of the screen, then select Settings. Here you should look for items related to Wallpaper or Lock Screen.
It's also worth checking if there's an automatic change for a particular album, and if you've ever set up wallpaper from a gallery and ticked "Repeat," the system will cycle to change images from the selected folder, and turn that off when you install new wallpaper or through the current set management menu.
| Function | Wherever | Action. |
|---|---|---|
| Wallpaper carousel | Settings → Lock screen | Turn off the switch. |
| Scheduled shift | Gallery → Settings | Uncheck "Daily" |
| Topics (Shop) | Annex Topics | Remove the subject to the classic |
Importantly, newer versions of HyperOS can combine settings into a single personalization center, and if you don’t find the right options in the old sections, look for them in the Personalization app.

Impact of Third-Party Apps and Themes
It's not just system services that can change your background. Third-party apps downloaded from Google Play or GetApps often ask for permission to change wallpaper, especially for cleaners, antiviruses, weather widgets and, of course, apps with live wallpaper.
If the problem started after installing a certain software, there is a high probability that the culprit was found, and often these applications have a built-in "Daily Wallpaper" function that is activated by default.
- 🔍 Think about what apps you installed before the problem occurred.
- 🛑 Check the permissions: Settings → Protection of confidentiality → Permit Controller → Change of wallpaper.
- 🗑️ Remove or disable suspicious applications.
⚠️ Warning: Be careful with Live Wallpapers apps. Even if you haven't chosen to change static images, some of them can be reset to standard ones when battery power is low to save energy.
Also worth checking out is Themes, which, if you have a third-party theme installed, can dictate its own design rules, including changing wallpapers, try applying a standard Classic or Default theme and follow the system's behavior.

Synchronization and account Mi Cloud
In the Xiaomi ecosystem, devices can synchronize your design settings through the Mi Cloud. If you use multiple Xiaomi devices (like a phone and tablet) and log in to the same account, changing the wallpaper on one device can automatically apply them to another.
Check your sync settings. Go to Settings → Mi Account → Mi Cloud. Make sure that synchronizing themes or system settings is not set to fully copy the design between gadgets.
Also, some themes from the official theme store can be updated automatically, so the theme developer could add a new set of wallpapers to the update, and the system used them as an improvement, in which case only changing the theme to static or removing the theme from the device memory will help.
If you recently reset your phone or restored data from a backup, the system could tighten your old settings, including active subscriptions to change images, in which case manually checking all of the above points is mandatory.
💡
Sync through Mi Cloud is a common reason why wallpaper changes across all user devices at the same time. Check the cloud settings if you have multiple Xiaomi gadgets.
Problems after system update
Updating the MIUI shell or switching to HyperOS often resets some user preferences to default values. After a major update, the system may suggest re-enabled wallpaper carousel or activate new personalization features that you previously disabled.
During the update, the wallpaper configuration files can get corrupted, causing random changes in images or displaying "broken" images, in which case cleaning the system interface cache helps.
To perform deep cleaning, you will need access to an engineering menu or ADB, but more often than not, standard tools are sufficient:
- Go to Settings → Applications → All applications.
- Find the Wallpaper app (or Themes).
- Select Clear → Clear cache (not data unless you want to lose downloaded themes).
- Reset the device.
If the problem occurs after the update, wait 1-2 days. the system conducts indexation and background optimization, during which some services may behave unstable.
Alternative solutions and wallpaper fixing
If standard methods don't work and wallpaper continues to "live its own life," radical but effective measures can be taken, and one way is to use third-party wallpaper fixing apps that take precedence over system settings.
Apps like Wallpaper Changer or Mutewall allow you to not only change wallpapers, but also block other programs from changing them, and by installing such an application and selecting one picture at intervals of "never" or "24 hours", you will block access to the lock screen for system services.
It's also worth checking the power saving mode. In some scenarios, when you turn on Ultra-Energy Saving, the phone forcefully changes the subject to black and can reset the wallpaper to standard to save charge. AMOLED-screen.
- 🔋 Check the energy saving settings.
- 🎨 Use third-party launchers (Nova Launcher, Niagara) that take control of the desktop.
- 🚫 Disable storage access for suspicious system services if possible without disrupting your phone.
⚠️ Warning: Installing third-party launchers can change the look of the interface.Make sure you can go back to the standard Xiaomi launcher if you don't like the new one.
