Xiaomi smartphone users often face intrusive design that appears after installing third-party themes from the official store. The lock screen begins to overwhelm advertising, unnecessary widgets appear, and the standard exterior shell of MIUI or HyperOS is distorted beyond recognition. This can be annoying, especially if you appreciate the minimalism and speed of the interface.
Fortunately, the Chinese manufacturer's Android system allows for a fairly flexible management of visual elements, and you can remove themes in a number of ways, from simply switching to a classic style to completely deleting files through the file manager. It is important to understand the difference between a theme that uses icons and a theme that changes the lock screen.
In this article, we will look at all the available methods of returning to the factory appearance, you will learn how to disable the “Wallpaper Carousel”, which is often a source of intrusive content, and how to clean the system of debris left by experimental designs.
Disconnection of wallpaper carousel as a source of topics
Most people who use "themes" on the lock screen are "Glance," which automatically uploads images and news, often turning into an advertising platform, and you don't have to manually delete files to get rid of that.
Just go to the lock screen settings. Find the switch to change the images, and just turn off the switch. The interface will immediately become static, and third-party images will stop loading.
If a standard shutdown doesn’t work, the theme may have stuck in the theme cache, so you need to clear the file itself, which will return the theme store to its original state, but won’t delete the files you already installed, so the next step is critical.
⚠️ Warning: After the wallpaper carousel is turned off, old uploaded images may remain in the gallery.Check out the wallpaper carousel album and manually remove its contents to make room.
Resetting the topic through the “Themes” app
The most legal and safe way to get back to the standard look is to use the built-in Theme app. Even if you downloaded the design from a third-party source, Xiaomi tries to manage it through this service.
In the My Themes section, you'll see a list of all the designs ever installed, and it's important to find the Classics or Default item, and clicking on this icon will instantly reset all visual changes, returning the standard icons, fonts and wallpaper.
However, if the theme has been installed with errors or corrupted, the application button for the classics may not work, in which case, try first to remove the problematic theme from the list of My themes by holding your finger on it and selecting the appropriate menu item, and only then apply the standard.
☑️ Verification of the resetting of the topic
Sometimes the system requires a reboot after applying a classic theme. Don't ignore this request, as some interface elements, such as the notification bar, are only updated after the full cycle of the device's switching off and on.
Delete theme files through the file manager
If the software reset doesn't work, you'll have to go a little bit further, delete the files manually. Xiaomi's Android file system stores the data on the themes in hidden directories. You'll need a file manager with permissions to access the system folders or a standard explorer with hidden files enabled.
You need to find the MIUI folder at the root of the internal memory, and that's where all the user data is stored, and inside that directory, we're interested in the theme folder, and that's where the installed file is.
Be careful: deleting unnecessary files can cause the system to temporarily lose its design, which is normal, after rebooting, it will tighten the standard package, the main thing is not to delete the system files responsible for the basic operation of the interface.
Which folders can be removed safely?
Once the folders are cleaned, be sure to reboot the device completely, allowing the system to reassemble the cache of resources and apply the changes correctly.
Comparison of methods of deleting topics
The method you choose depends on how deeply the theme has been embedded in the system. Simple switching may not remove the ad modules, and manual deletion of files requires care. Below is a table to help you choose the right approach.
| Method | Difficulty | Efficiency | Risk of error |
|---|---|---|---|
| Application of the classical theme | Low. | Medium | Minimum |
| Cleaning the data of the “Themes” application | Medium | Tall. | Low. |
| Delete files through the conductor | Tall. | Maximum | Medium. |
| Resetting phone settings | Tall. | Maximum | High (data loss) |
As you can see from the table, for most users, cleaning the application data or applying a classic theme is the best option. Manual deletion of files should be used only in extreme cases when other methods have not worked.
Factory reset is a last resort, and should be used if the theme has caused a critical system failure and the phone is not working properly. Always back up important data before doing so.
Elimination of Advertising and Widgets After Deletion
Even after the theme is removed, artifacts can remain on the screen: empty widgets, modified fonts or banner ads in system applications, because the themes often modify not only the appearance, but also the system settings.
To start, check the Receiving Recommendations settings. This service at Xiaomi is responsible for displaying ads in system applications. Turn it off under Passwords and Security -> Access to Personal Data. Search in the msa list and turn off the slider.
Then, go through your desktops, remove any widgets that look suspicious or lead to unknown sites, and often theme sets up their own weather or news widgets that continue to work even after the change of design.
💡
If the font remained changed after the theme was deleted, go to the theme settings, select the Fonts section and force the standard font Mi Sans or Roboto.
Also worth checking is the Always On Display settings, theme can change the style of displaying time and notifications on the locked screen, reset these settings to factory settings in the Lock Screen menu.
What to do if your phone goes into a cyclical reboot
In rare cases, an incorrectly installed or deleted theme can lead to a “bootloop” — a cyclic reboot of the phone. The screen goes out, the logo appears, and the process repeats indefinitely.
The first thing you should try is to boot into Safe Mode. To do this, when you turn on your phone, when the Xiaomi logo appears, press the volume button. The system will boot with third-party themes disabled. If the phone is turned on, immediately delete the problematic topic.
If Safe Mode doesn't work, you'll have to use Recovery Mode. Press the power button and turn up the volume. In the recovery menu, select Wipe Data. Remember, this action will delete all data from your phone.
⚠️ Note: Signing in to Recovery Mode and Wipe Data will completely destroy all photos, contacts and applications on your device. Use this method only if other methods do not work and you have a backup.
Once reset successfully, the phone will return to factory status, all the themes will be removed, and the system will work as new, a guaranteed way to get rid of any software conflicts associated with the design.
Preventing problems with topics in the future
To avoid having to delete themes and clean the system, you should follow simple digital hygiene rules, first of all, download designs only from official sources or trusted communities.
Pay attention to the permissions that the theme requests when installing. If simply changing icons requires access to contacts, geolocation, or microphone, that's a wake-up call. Never install themes that require excessive access rights.
Check your installed app list regularly, sometimes with the themes that come with the "junk" optimizers or cleaners that are the source of the problem, and remove them as soon as you find them.
💡
Use only official themes from the high-rated MIUI/HyperOS store to avoid viruses, advertising and system instability.
It’s also helpful to periodically clean the cache of the Themes app, which won’t delete your purchases or downloads, but will remove temporary files that may be taking up space and causing interface errors.
