Owners of Xiaomi, Redmi and POCO smartphones often face the desire to personalize their device’s interface. One of the most visible elements of the system we see every morning is the lock screen and, in particular, the alarm clock. The standard design offered by the developers of the MIUI or HyperOS shell can seem boring or impractical. Fortunately, the Android system allows you to make changes to the visual component, making use of the gadget more enjoyable.
The process of changing the background depends on the specific version of the operating system and the theme installed. In some cases, it is enough to simply choose a new theme, in others you will need to manually adjust through system applications. It is important to understand that the MIUI shell has its own features that distinguish it from stock Android, which is why standard methods may not work if you do not take into account the nuances of the firmware.
In this article, we will take a look at all the ways you can change the alarm clock, how to use built-in personalization tools, where to look for hidden settings, and what to do if the desired image is not set. The Superstorm or Wallpaper Carousel function can block the manual change of the alarm clock background, so they often need to be turned off for custom images. Let's start setting up your device.
Features of the alarm clock interface in MIUI and HyperOS
The interface of the standard Watch app in Xiaomi smartphones is closely integrated with the general theme system.This means that the appearance of the dial, buttons and, of course, the background, is often dictated by an active theme. Unlike many other manufacturers, Xiaomi does not always provide a direct “change background” button inside the alarm app itself.
Users have to distinguish between the background of the lock screen and the background of the alarm clock that is ringing directly. These are two different visual layers. When the timer is triggered, the system accesses the resources of the active theme. If the theme does not support changing the background, you will not be able to change the picture using standard methods, in which case third-party solutions or changing the topic entirely come to the rescue.
It's worth noting that in the new versions of HyperOS, the algorithms for widgets and system clocks have been redesigned, and now the system is more actively using dynamic elements that can overlap a static image. So it's important to consider the contrast and readability of numbers when choosing a picture. Too colorful background can make time indistinct at the moment of waking up.
Change the background through the “Themes” app
The most reliable and formal way to change the visual design of the alarm clock is to use the built-in Themes app. This is where all the graphic resources that the system uses are stored. The algorithm of actions is simple: you need to find the theme that implements the desired design of the alarm screen. Not all themes support this feature, so you should be careful when choosing.
To start, open the Topics app on your smartphone. Type keywords like “Clock,” “Alarm” or simply go through popular categories in the search box. In the preview of the topic, you can often see what the lock screen and alarm clock look like. However, to make sure you have the right background, the topic is best applied first.
After applying the theme, check the alarm clock. If you like the new design but don't like some other element (like icons), you can combine elements of different themes. In the Profile section (human icon), there is a Settings item where you can select Components. Here you can change fonts, icons and, in some cases, system clocks separately from the rest of the the the theme.
- 🎨 Open the Topics app and go to the “My Pages” or “Profile” section».
- 🔍 Use search on “Alarm Clock Style” to find specialized designs.
- ⬇️ Download and apply the theme by pre-checking the alarm screen preview.
- ⚙️ In the theme settings, try changing only the System Watch component if you don’t want to change the entire interface.
⚠️ Note: When installing themes from third-party sources (not through the official Xiaomi store), there is a risk of system failure.
Use of the "Wallpaper Carousel" function
One of Xiaomi's unique features is the "Wallpaper Carousel" (Glance), which automatically changes images on the lock screen, taking them from cloud storage. Many users wonder if this affects the alarm clock. There is no direct connection, but Carousel can block the ability to set a static background for the alarm if there is a conflict of priorities in the system.
If you want to set your photo on your alarm, but you have a wallpaper carousel active, the system may ignore your choice in favor of a dynamic screensaver. In this case, it is recommended to temporarily turn off the service. You can do this through the lock screen settings. The path usually looks like this: Settings → Lock screen → Wallpaper carousel.
Once you turn off the service, you have full control over static images. You can now set any photo from the gallery as a background, and it won't be replaced by promotional content or news feed. This is especially true for those who prefer minimalism and specific images over random selection.
How to completely remove the wallpaper carousel?
Customize your own images through the Gallery
The most direct way to set a specific image is to use the standard Xiaomi gallery. This method works if an active theme allows you to replace the background. First, select a quality photo in the Gallery app. The image should be vertical and have sufficient resolution so that it does not look blurry on the screen of your smartphone.
Open the selected photo, click on the menu (three dots or swipe up) and select Set as wallpaper. In the menu that appears, the system will suggest choosing whether to apply the image to the main screen, lock screen or both. For an alarm clock, it is critical to choose a lock screen, since this layer is often used when the alarm clock rings depending on the topic.
Once installed, the system may suggest framing the image. Make sure that the central part of the photo is not cropped, as this is where the time digits are often located. If the old picture is left in the alarm clock after setting the background, then the current topic has rigidly fixed its background, in which case a return to the step with the choice of the topic is mandatory.
☑️ Checking before setting the background
Compatibility table of MIUI methods and versions
The effectiveness of different methods may vary depending on the software version, and below is a table that will help you navigate which method is most likely to work for your configuration.
| MIUI/HyperOS version | Shifting through Topics | Direct installation of photo | Wallpaper carousel |
|---|---|---|---|
| MIUI 12 / 12.5 | Tall. | Medium | Active by default |
| MIUI 13 / 14 | Tall. | Low (depending on the topic) | Demands a shutdown. |
| HyperOS 1.0 | Limited. | Medium | Integrated deeply |
| Global ROM | Complete. | Tall. | Optionally. |
| China ROM | Complete. | Low. | Often without removal |
As you can see from the table, global firmware owners have more freedom in settings, and Chinese users (CN ROMs) often have to resort to installing global themes or using third-party apps to achieve the same result, due to different policies for monetizing and promoting services in different regions.
Third-party applications for alarm clock customization
If Xiaomi’s standard tools don’t work, Google Play apps come to the rescue. There are many quality alternatives to the standard alarm clock that offer a wide range of background settings, and can not only show your photo, but also display the weather, currency rates or motivational quotes.
A popular solution is the Alarmy or AMdroid app, which allows you to set any image from the gallery as a background, and even more so, some of them have a "task" feature, like solving a math problem to turn off the sound, which ensures that you actually wake up, rather than just swipe the notification.
When using third-party software, it is important to configure permissions correctly. Android can aggressively kill background processes to save battery. To get the alarm to work on time, you need to go to Settings → Applications → Find your alarm → Autostart (on) and select No restrictions at Battery.
💡
For maximum alarm reliability on Xiaomi, always add the app to the Favorites or No Limits list in the battery settings, otherwise the system may block the sound in sleep mode.
The solution: why the background doesn’t change
Often users are faced with a situation where all actions are completed, but the background of the alarm remains standard. The most common reason is the theme cache. The system could save old graphic files in memory and not update them, in which case it helps to clear the cache of the application Themes and Watch through the application menu.
Another possible problem is the use of Superbugs. This dynamic saver mode is of the highest priority and blocks any other changes to the background of the lock screen. To check this, go to Settings → Wallpaper and make sure that you select a static image, not the category of Superbugs or Planet.
It’s also worth checking whether Do Not Disturb mode or special access modes are enabled that can simplify the interface beyond recognition, and in some cases, a simple restart of the device that forcibly updates all system resources and applies new theme settings helps.
⚠️ Note: If you upgrade to a new version of Android or MIUI, This is normal behavior, because new versions of the OS often change the structure of the registration files.
💡
The main reason why you can't change the background is the conflict between the active theme and manually setting the wallpaper, so you can either change the theme to supportive customization or use a third-party alarm clock.
