Xiaomi smartphone users often face a situation where standard personalization tools stop working as intended by developers. In particular, the lock screen can ignore attempts to change the appearance of the dial, leaving a default style that may not fit the set theme. This is not always a critical system error, but causes tangible discomfort to those who are accustomed to full control of the interface.
The reasons for this behavior can be found both in software thematic conflicts and in the specific energy saving settings characteristic of the MIUI or HyperOS shell. System time widgets often take priority over user settings if certain functions are activated, such as Wallpaper Carousel or third-party launchers. Understanding the architecture of the shell allows you to quickly find the root of the problem and eliminate it without the need to flash the device.
In this article, we will take a look at all possible scenarios for ignoring the choice of a new style, and offer step-by-step instructions for restoring functionality. You will learn about the hidden limitations of regional versions of firmware and how to properly apply themes from the GetThemes store so that they correctly display on a locked screen.
Thematic Conflicts and System Limitations of MIUI
The main reason why the watch style refuses to change is the conflict between the active theme and the system components of the shell. The MIUI shell, and now HyperOS, uses a complex layering system where system time widgets can take higher priority than graphical theme elements. If you installed a theme from a third-party source or updated an existing one but the changes didn't apply, there was probably a failure in the the theme resource cache.
Often the problem is that the theme chosen simply does not contain its own design for the lock screen and inherits the default system style. In the theme store, this is not always obvious, since the preview may show a modified interface, but the real configuration file may be empty for this particular element. Many global firmware versions have strict restrictions on changing system fonts and time widgets in order to comply with license agreements with Google.
To diagnose, you need to check whether the problem is global or just a specific style. Try applying a standard theme "Classic" or "Standard" in the "Themes" app. If after that the clock has changed to standard (even if you don't like them), then the replacement mechanism works, and the problem is in the files of the previously installed custom theme.
Also, regional features should be considered (CN) and Russia/Europe (RU/Global) The mechanisms of the lock screen may differ, and the Chinese versions often allow you to change fonts and styles deeper, while the global ones can block the change of the system. UI-elements at the core level of the system to ensure stability.
The Influence of Wallpaper Carousel and Always On Display
One of the most common reasons to block the change in style is the active Wallpaper Carousel feature, which is designed to regularly update the background image, often takes over control of the lock screen rendering, and when the Carousel is active, it can force its own time display style to be set, ignoring the settings of the theme you choose.
A similar situation is observed with Always On Display (AOD). If you have a permanent screen on or activate it on a schedule, the system can block the change in the main style of the watch, since AOD has its own set of widgets.
⚠️ Attention: An active wallpaper carousel may consume additional battery power and Internet traffic to upload new images. If you don't need to change your background daily, consider turning it off to improve your autonomy.
To check the impact of these functions, follow the following steps:
- 📱 Go to Settings. → Lock screen and find the item "Carousel wallpaper».
- 🔌 Turn off the “Enable Wallpaper Carousel” switch and check if the selected watch style has been applied.
- ⏰ Go to Settings. → Lock screen → Always on Display and Lock screen.
- 🚫 Temporarily shut down. AOD Check the system’s response to the change of topic.
If the style of the watch changed after these features were turned off, then the conflict was the priority of the system services, you can leave them off or try to find a theme that is declared to be compatible with Carousel, although there are fewer and fewer of them in the store.

Errors of the “Themes” application and resource cache
The Themes app is the central node for managing the smartphone's visual style, and its incorrect operation often leads to display bugs.Accumulated cache, errors in the installed component database, or a resource loading failure can cause the new watch style to simply not boot.The system continues to display the old image from memory, ignoring the update command.
The first step in solving the problem is to clean up the theme application data, which will not delete your purchased or downloaded themes, but will reset the settings of the application itself and force the system to read the configuration files again. This is the standard maintenance procedure for Xiaomi system applications, which solves 80% of visual glitches.
☑️ Actions to clean up the cache of topics
Once the data is cleaned and the device is rebooted, you need to re-use the theme, sometimes re-downloading the theme from the cloud helps, go to the profile in the Themes app, find the theme you want, and click the download or re-use button, which will force you to update the files in the /data/theme folder.
It’s also worth checking for updates to the Themes and Wallpaper component itself. Theme store often comes out with patches that fix compatibility with newer versions of Android. If you have a beta version of the firmware installed, problems with themes are common, since theme developers do not always have time to adapt their products to changes in the system code.
Third-party widgets and launchers
Using third-party launchers (Nova Launcher, Niagara, Lawnchair) and widgets can make adjustments to the lock screen, although they usually do not control it directly. However, some launchers have their own lock screen settings or smart lock features that can override Xiaomi's system settings. If you use such applications, try temporarily disabling them or returning a standard launcher.
And then there are watch widgets that are set up as separate programs, and if you're trying to change the style of that widget, rather than the system widget, the settings in the Themes app won't help. You need to go into the settings of the widget itself, usually by long tapping the widget on the desktop or through the app menu.
Conflicts can also arise when using memory cleaner or antivirus applications that have a Blocker or Screen Improver function. Software such as Clean Master or various boosters can implement their own screen lock layer that defies standard MIUI theme.
| Type of intervention | Probability of conflict | Symptoms. | Decision |
|---|---|---|---|
| Wallpaper carousel | Tall. | The clock doesn't change, the background changes | Disable in screen settings |
| Third-party launcher | Medium | Changes to apply in part | Check the launcher settings |
| Cliner applications | Medium | Your lock screen. | Remove or configure the application |
| Always On Display | Low. | Style conflict on the off screen | Set priority in the display |
Regional features and firmware versions
It is important to understand that the functionality of personalization depends on the region chosen when you first set up your smartphone, and the type of firmware installed (Global, EEA, China, India). In the Chinese versions of firmware (CN ROM), the thematicization functionality is the most extensive and allows you to change almost any element, including system application icons and deep settings Always On Display.
Global and European versions (EEA) are often stripped down to comply with Google and local regulations, for example, in some regions, it may not be possible to download third-party themes without obtaining root rights or using special system modification tools. If you refashioned your phone from Chinese to global, you may lose the ability to use certain types of themes.
💡
Check the region in settings: Settings → Additional settings → Region. Changing the region to “India” or “China” will sometimes unlock hidden theme features, but can change the language of system applications and add unnecessary advertising services.
The Android version is also worth considering: the switch from Android 11 to 12, 13 or 14 introduces changes to the widget API. Old themes created for MIUI 11 or 12 may not work properly on HyperOS or MIUI 14/15 due to changes in the configuration file structure. Theme developers must update their products, but many popular themes remain abandoned.
Alternative methods of customization
If standard tools fail to change the style of a watch, there are alternative ways, one of which is to use widgets on the home screen that mimic the lock screen or simply provide convenient access to the time in the desired style, and while this does not change the system clock, it solves the problem of time visualization.
For advanced users, a method of modifying system files through root rights is available. Using file managers with access to the system partition (for example, MT Manager or Root Explorer), you can replace the graphics files of the clock in the theme folders. However, this method is highly skilled, since an error in the XML syntax or image format can lead to a bootloop (cyclic reboot) of the device.
Another option is to use customized lock screen apps from Google Play, which completely replace Xiaomi's standard lock screen.Apps like "Hi Locker" or "AcDisplay" offer huge customization options, but can conflict with biometric unlocking (a fingerprint or FaceID can work unstable).
⚠️ Warning: Installing third-party lock screens may disrupt the sleep-mode fingerprint scanner, as Android security restricts access to biometrics for third-party applications for data protection purposes.
In conclusion, the problem with the immutable style of watches on Xiaomi is most often solved by turning off the wallpaper carousel or cleaning the cache of the Themes app. In rare cases, a deeper intervention in system settings or changing the regional binding of the device is required.
💡
The main reason for ignoring the style of the watch is the conflict of priorities between the Wallpaper Carousel, Always On Display and the active theme.
