How to remove themes from the lock screen Xiaomi: a complete guide

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.

📊 What annoys you the most about Xiaomi topics?
Advertising on the lock screen
Difficulty in removal
System instability
Lack of standard functions

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.

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?
In the theme folder, you can delete files with the.mtz extension that match the name of the downloaded themes. Do not touch files with default, classic or system files without extensions. If in doubt, you better rename the folder by adding suffix" old" and check the phone's performance.

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.

MethodDifficultyEfficiencyRisk of error
Application of the classical themeLow.MediumMinimum
Cleaning the data of the “Themes” applicationMediumTall.Low.
Delete files through the conductorTall.MaximumMedium.
Resetting phone settingsTall.MaximumHigh (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.

Frequently Asked Questions (FAQ)

Can I delete the theme if my phone is not unlocked?
If the phone is locked because of a theme (black screen, freeze), try booting into Safe Mode by pressing the volume button at start. If that doesn't help, you'll need to log in to Recovery Mode and a full Wipe Data reset, which will delete all files.
Where are the theme files stored on Xiaomi?
Theme files are usually in the hidden system folder /data/system/theme/ or in the internal memory in the MIUI/theme folder. The first path requires Root rights, the second is accessible through a file manager with hidden files.
Why did you leave the topic with ads?
Advertising may not come from the theme itself, but from the MSA (MIUI System Ads) service or from a separate application that has been installed with the theme. Check the list of installed applications and disable ad personalization in the security settings.
How to return standard icons if they are not restored?
Go to the Themes app, go to your profile, and select the Icons section. There should be a Reset option or the option to select a standard set of icons. If it doesn't work, clear the Themes app data in your phone settings.
Does removing themes affect the guarantee?
No, using and removing themes through the standard Themes app or file manager does not violate the warranty. The guarantee is lost only when unlocking the bootloader and obtaining Root rights for system modifications.
