Owners of Xiaomi, Redmi and POCO smartphones often face a situation where wallpaper suddenly changes on a locked screen, news widgets or banner ads appear, usually after another MIUI or HyperOS update, when the background service is activated without the user's knowledge, many people perceive this as a virus, but in fact it is a regular feature called Wallpaper Carousel.
Developers have implemented this mechanism to monetize their budget devices by providing users with personalized content in exchange for attention to advertising integrations. However, for those who value cleanliness and data privacy, the appearance of extra elements on the lock screen becomes a serious problem that needs to be addressed.
In this article, we will take a closer look at what the Wallpaper Carousel name is, what permissions it requests, and why Android’s security system might flag it as a potentially unwanted app.
The essence of the Wallpaper Carousel service in the MIUI ecosystem
At its core, Wallpaper Carousel is a system application that automatically changes background images on the lock screen, part of the standard set of services for Google and Xiaomi, pre-installed on the brand’s devices, and the app’s functionality goes far beyond simply changing pictures.
The main purpose of the service is to collect data about user preferences. By analyzing which images you like, which you skip or block, the algorithm forms an advertising profile, which is why you often find the requirement to access geolocation or browser history in the settings, which raises legitimate security questions.
It's worth noting that the app is tightly integrated with the MIUI shell, and it doesn't just change the image, it can load up weather widgets, currency rates, or news briefs, which for many users seems convenient, but for others, it's a waste of RAM and traffic.
⚠️ Note: The app may request redundant permissions, such as access to contacts or microphone, that are not formally needed to change the wallpaper.
It's important to understand the difference between a standard wallpaper gallery and a carousel. If the former simply stores static images, the latter is an active network service, constantly connected to the developer's servers to retrieve new content.
The main functions and capabilities of the service
Despite its controversial reputation, Wallpaper Carousel has a number of useful features that have been appreciated by millions of users around the world.The service offers access to a huge database of high-quality images, sorted by categories: nature, architecture, abstraction and art.
The key feature is that you can subscribe to specific topics, so you can customize the system to only show space scenery or animal photos, and that creates a sense of personalization without having to search for and install new wallpaper.
- 🖼️ Automatically upload new images from the cloud without user input.
- 🔒 Ability to display useful information (time, date, notifications) over changing backgrounds.
- 🌍 Support for regional collections, allowing you to see wallpaper, popular in different countries of the world.
However, the functionality often depends on the region specified in the smartphone settings, for example, when choosing a region “India” or “Russia”, the number of ad integrations can differ significantly from the version for the global market.
The hidden potential of the carousel
Also worth mentioning is the "Recommendations" function, which analyzes the time of day and can offer brighter and richer images in the morning, and calmer, darker tones in the evening so as not to irritate the eyes before bedtime.
Impact on the performance and battery of the device
One of the most common questions users ask is, “How much does Wallpaper Carousel put down the battery?” because the app is a system process, it runs in the background, periodically accessing the network to update content.
Energy consumption is directly related to the frequency of wallpaper change. If you set the interval "Every screen turn on" or "Every minute", the charge consumption will be noticeable, especially on older models of smartphones with a worn-out battery. In "Daily" mode, the impact on autonomy is minimal.
In addition, the service takes up space in RAM: on devices with 4 GB of RAM or less, this can lead to more frequent unloading of background applications from memory, which is subjectively perceived as system brakes.
| Parameter | Impact without optimization | Influence with settings |
|---|---|---|
| Traffic consumption | Up to 100MB a day | Only Wi-Fi. |
| Employment of RAM | 50-80 MB is constant | 10-20 MB |
| CPU loading | Short-term peaks | Minimum |
For owners of budget models of the Redmi or POCO M series, it is recommended to limit the background activity of the service to maintain the speed of the interface.
💡
If you notice that the phone is quickly discharged, try in the settings of the carousel to turn off the download of images through the mobile network, leaving only Wi-Fi.
It is also worth considering that the constant access to the storage to record new cached images can theoretically accelerate the wear of flash memory, although on modern drives this effect is almost invisible.
How to completely disable Wallpaper Carousel
If you decide that the benefits of the service do not outweigh the disadvantages of advertising and resource consumption, you can turn it off. Standard system tools do this is not always obvious, as Xiaomi masks this option.
The first step is to find the app itself, and it can be called Wallpaper, Wallpaper Carousel, or Wallpaper Carousel. Go to Settings. → Annexes → All applications. Find the service you want on the list.
☑️ Checklist for shutdown
After entering the app menu, click on the “Delete Updates” button, which will return the app to the factory version, where the carousel functionality is often cut down or disabled by default. Then go to the “Other permissions” section and deny access to all items, especially “Autostart” and “Master over other windows”.
The next step is to disable through the lock screen settings. Go to Settings → Always on screen and lock screen. Find the wallpaper carousel and put the switch in an inactive state.
⚠️ Note: On some global firmware versions, the “Disable” button may not be available (blacked out). ADB or installing modified launchers.
After these steps are completed, the system will stop downloading new images, and a static picture selected by you manually will remain on the lock screen.
Removal via ADB for advanced users
For those who want to get rid of the system debris and are not afraid to work with code, there is a method of debugging via USB. This method requires a computer and the presence of ADB drivers.
First, activate the developer mode, and then seven times click on the build number in the About Phone menu, then turn on USB debugging in the Developer menu.
adb shell pm uninstall -k --user 0 com.miui.misystemThe above command will remove system components associated with advertising and carousel. However, be careful: the name of the package may vary depending on the version of MIUI. Wallpaper Carousel often uses the package com.miui.wallpaper or com.android.thememanager.
- 🛠️ Connect your phone to your PC in file transfer mode.
- 💻 Run the command line in the folder with ADB.
- 📱 Enter a command to remove a specific package.
Using ADB allows you to delete the application for the current user without disturbing the integrity of the system partition, which means that when you reset to the factory settings (Hard Reset), the application will return, but in normal operation it will not.
💡
The ADB method is the most effective way to remove Xiaomi system applications without obtaining Root rights.
Alternatives and setting up static wallpaper
After turning off the carousel, the question arises: where to get quality wallpaper? the standard Xiaomi gallery offers a good choice, but you can take advantage of third-party solutions that do not impose advertising.
An excellent alternative is apps like Google Wallpaper or specialized services like the Wallpaper Engine (for live wallpaper), which allow you to set up a schedule for changing images, but do it locally, without constantly communicating with the server and collecting data.
You can also create your own "picture" from your favorite photos. Upload the album to the gallery, select the image and set it as wallpaper for the lock screen. Now your phone will show exactly what you want, not the algorithm of the ad network.
⚠️ Warning: When installing third-party wallpaper apps, check their permissions. Some lightweight wallpapers may request network access and contacts, which is suspicious behavior.
For minimalist fans, it is recommended to use static images of dark colors. This not only looks stylish, but also saves battery power on AMOLED screens, which are installed in many Xiaomi flagships.
