Xiaomi’s current smartphones, including the popular Redmi 9, offer users a wide range of options for personalizing the interface. One of the most sought-after features is the ability to install a dynamic image carousel that changes the background of locking or desktop every time you turn on the screen. This not only graces the device, but also allows you to enjoy a variety of visual content without the need to manually switch pictures.
However, many device owners have difficulty trying to activate this feature, as standard settings are sometimes hidden or incorrect due to regional firmware limitations. Redmi 9 owners often wonder why they don’t have automatic image change, although in brand advertising this feature is positioned as a key feature, the answer lies in the features of the MIUI shell and the need to properly configure system components.
In this article, we will discuss in detail all ways to install wallpaper carousel, from the standard system tools to the use of specialized applications. You will learn how to circumvent possible restrictions, where to download high-quality thematic collections and how to optimize the operation of the device so that changing the background does not affect the speed of unlocking.
Features of the MIUI interface and the blocking functionality
The MIUI shell installed on the Redmi 9 differs significantly from pure Android in its depth of visual adjustment. The system offers two main types of dynamic background: Wallpaper Carousel, which changes images on the lock screen, and Live Wallpaper, which works on the desktop. It is important to understand the difference, since the methods of activating them differ.
Xiaomi’s carousel feature is designed to save resources, but requires a stable Internet connection to upload new images. The algorithm is built so that every time a LockScreen device wakes up, it accesses the update server to get a new image from the selected category. If the server is unavailable or the wrong region is selected, the function may not work.
It’s worth noting that on global firmware versions for Redmi 9, some features may be limited compared to the Chinese versions, due to licensing agreements and regional content distribution features, so activating the carousel sometimes requires additional actions, such as changing the region in settings or installing updates to system components.
⚠️ Warning: When using third-party themes and carousels from unreliable sources, there is a risk of implementing advertising code that can slow down the smartphone.
Redmi 9 users should remember that an active wallpaper carousel consumes additional battery power, albeit minimal.The system is optimized to boot in the background, but with a weak network signal, the processor can spend more energy finding a connection.
Activation of the regular wallpaper carousel through settings
The easiest and safest way to set up a change of images is to use the built-in functionality of the system. This does not require downloading additional applications, since the component is already integrated into MIUI. However, the interface may not be obvious to beginners, so let's consider a step-by-step algorithm of actions.
First, go to the device settings menu. Find Settings → Wallpaper or Settings → Lock screen. Depending on the MIUI version on your Redmi 9, item names may vary slightly. From the menu that opens, select Wallpaper Carousel or Wallpaper Carousel.
Once you log in to the merry-go-round menu, the system will suggest you turn on the function. Activate the switch at the top of the screen. You'll then be asked to select the subject of the images: nature, cities, art, sports or animals. The category choice determines which content will be loaded onto the lock screen.
☑️ Checking the carousel settings
An important point is to adjust the refresh rate. In some versions of the firmware for Redmi 9, the option “Update each time the screen is turned on” is available. If this option is not active, images may change less often, for example, once an hour or once a day. For maximum dynamics, make sure that the carousel settings allow data transfer in the background.
You can also set up widgets on top of the carousel in this section, and you can choose whether you'll see hints, image descriptions, or feature quick buttons, which makes the lock screen more informative, but can overload the image visually.
Using the “Themes” application for enhanced features
If standard settings aren’t enough, the main customization tool in the Xiaomi ecosystem is the Themes app. This is where the bulk of content, including complex effects and animation carousels, is concentrated. For Redmi 9, it’s the main source of quality visual solutions.
Open the Themes app on your device. At the bottom of the screen, look for the Profile tab or the person icon. The menu that opens often hides the Settings or Wallpaper Carousel option, which duplicates system settings but with more access to the online directory, and you can download additional image packs here.
The Themes app has a Carousel section that shows the pre-made kits, and you can select the set, click Download and then Apply, and the peculiarity of this method is that some sets contain not just photos, but short video screensavers or interactive touch-responsive elements.
| Type of content | File size | Impact on the battery | Network requirements |
|---|---|---|---|
| Static carousel | 2-5 MB | Low. | Only when loading. |
| Video carousel | 10-50 MB | Average. | Wi-Fi is recommended |
| Interactive theme | 20-100 MB | High. | Stable Internet |
| HD Photo Packages | 5-15 MB | Low. | Mobile Internet |
When loading heavy themes via mobile Internet, the system can issue a traffic warning. For tariff owners with a traffic limit, it is better to use Wi-Fi. After applying the theme, the carousel is activated automatically, and the old settings can be overwritten.
What to do if the carousel is not loaded?
Third-party apps for desktop slideshows
Xiaomi's regular carousel works primarily on the lock screen, and if you want to make the changeable wallpaper directly on your desktop, it's harder to do that with standard tools, and this is where third-party solutions come in from the Google Play store.
One popular solution is to use slideshow widgets, you can install a widget-enabled gallery app, add a widget to the Redmi 9 desktop and set up an image folder, but it's not a full-fledged wallpaper, but a widget that can overlap application icons.
A more advanced method is to use launcher applications or specialized programs for live wallpaper, such as the Wallpaper Engine (requires a PC to set up) or Muraho Wallpaper, which allow you to create complex scenarios for changing the background. For Redmi 9 with its Helio G80 processor, these applications work stably, but require special permissions.
When installing a third-party wallpaper app, MIUI can aggressively close it to save energy. To avoid this, you need to manually set up autostart and work in the background. Go to Settings → Apps → [Your app] → Battery and select No Limits mode.
⚠️ Warning: Third-party applications for live wallpaper may conflict with the system theme of the design, causing the disappearance of icons or incorrect display of fonts.
The advantage of third-party solutions is their versatility: you can upload photos from any source, including Google Photos cloud storage or Dropbox. This allows you to create a carousel from personal photos, which is impossible with a standard Xiaomi carousel that works only with server content.
💡
To create a personal carousel from the photo, use the application "Live Wallpaper Picker" or analogue, pre-create an album in the gallery and allow access to it.
Set up Xiaomi regions and services to work
Often, the reason for a broken carousel on Redmi 9 is the wrong region. Xiaomi services are geolocated, and the content of the carousel may not be available to some countries. Changing the region is a simple but effective trick.
Go to Settings → Additional settings → Region. Try to set the region “India”, “Nepal” or “Russia”. In these regions, the wallpaper carousel service usually works most stable and has the most content. After changing the region, the phone may require a reboot or restart services.
You also need to check the status of Xiaomi’s service framework. In the application menu, look for Services and Feedback or Mi Service Framework. Make sure that this system application has Internet access and geolocation. Without this, the carousel will not be able to determine your time zone and download the corresponding images.
If you are using the global firmware version but are in a region where services are limited, you may need to log in to Mi Account. Go to your account settings and make sure sync is enabled, ensuring that your preferences and downloaded themes are maintained when you reset.
💡
Changing the region to India or Russia solves the problem of lack of content in the wallpaper carousel on global firmware in 90% of cases.
Optimization and Elimination (FAQ)
After installing the carousel, users may notice some changes in the behavior of the smartphone. This is normal, since the system adapts to new tasks. However, if the device starts to work slower, it is worth checking the autoboot list and disabling unnecessary processes.
Redmi 9 is very important to clean the cache periodically, especially if you change themes frequently. Accumulated temporary image files can take up hundreds of megabytes. Use the built-in Cleanup tool in the Security app to remove debris without affecting personal photos.
It is important to keep an eye on system updates. Xiaomi regularly releases patches for MIUI that fix bugs in the lock screen. Go to Settings → About the phone and check for updates. Sometimes the problem is solved by simply updating to the version with the bug fixed.
