The interface of a smartphone is the first thing we see after the screen is turned on, and often owners of Xiaomi and Redmi tend to personalize it with third-party themes. However, over time, the visual style can get bored, and poorly made wallpaper or icons begin to annoy and interfere with navigation. A natural question arises: how quickly and safely to remove the theme on the Xiaomi Redmi Note, returning the system to its original appearance or installing a new design?
The process of changing or removing the design in the MIUI shell and the new HyperOS is not always obvious, especially if the standard Themes app has been removed or hidden. In this article, we will discuss all possible ways to return to factory design, including working through system settings, hidden menus, and even using a computer for advanced users.
It’s important to understand that deleting a theme isn’t just about erasing a file, but resetting an interface configuration that affects the lock screen, control panel, and system fonts. Wrong actions can leave your phone with broken icons or a black lock screen. So follow the instructions carefully to avoid visual bugs.
Standard Resetting Method through the Topics App
The easiest and safest way to get back a stock design is to use the built-in Theme app. Even if you downloaded the design from a third-party source, Xiaomi still registers it with this manager. To remove an active theme, you don't have to search for files in your phone's memory; just use the profile functionality.
Open the Themes app on your Redmi Note. If an icon has been removed from your desktop, search for it through your app search or in the Tools folder. In the lower right corner of the screen is your profile icon (humans), click on it. Here you can see all the designs you have downloaded, including system and user.
In the My Themes section, you'll see a list of all the designs ever installed. Find a theme called Classic or Default. Click on it, then select Apply. This action instantly replaces the current design with factory design, effectively removing visual changes to the third-party theme.
If you want to completely remove a downloaded theme file from your device’s memory so it doesn’t take up space, find it in the list of My Topics, click on the information icon or hold your finger for a preview. In the menu that appears, select Delete. The system will request confirmation, as this action is irreversible without re-uploading the file.
Remove through screen settings and locking
Sometimes the Themes app doesn't work properly or freezes when you try to change the design, and in these cases, the system settings of the display come to the rescue, which allows you to reset the lock theme and the theme separately, which is useful if the problem lies in only one of these components.
Go to the main smartphone settings menu and select the Screen always on and Lock screen (or simply Lock Screen depending on the Android version) to control the screen behavior when you turn on, and if you have a third-party lock theme installed, it may conflict with fingerprint unlock.
To reset the block topic:
- 📱 Click on “Online Resources” or “Theme Gallery” if it is active.
- 🔄 Select a standard lock theme from the preinstalled list.
- ✅ Confirm the application of the changes, after which the old style will be removed.
⚠️ Warning: If after changing the theme of the lock smartphone stopped responding to swipes or buttons, try to restart the device by pressing the power button on the device. 10-15 This will force the Keyguard system to restart.
It’s also worth checking the font settings, as they often come bundled with themes. In the Settings menu → Screen → System Font, you can return the standard Mi Sans or Roboto font. Removing the third-party font will automatically update the text display in all applications, eliminating possible artifacts.
☑️ Check before deleting the topic
What to do if the Topic app is removed or hidden
Users often delete the Themes system application to free up space or as part of Debloat procedures, in which case the standard path through the profile becomes unavailable, but the MIUI shell allows you to restore access to theme management even without the reinstall application.
The first way is to use region settings. Sometimes changing a region from Russia to India or the United States will force you to update the system component list and return access to basic design features. Go to Settings → Additional settings → Region and select any other country, then check if the app appears on the menu.
The second way is more radical: reset all the design settings through the developer menu or special commands, and if the application is deleted but the topic is hanging, you can try to clear the system component of miui.theme.
- Open Settings → Applications → All applications.
- Click on three dots in the corner and select “Show System Processes”.
- Find the list of “Themes” or “MIUI Theme Manager”.
- Press Clear Clear. → Clear everything.
⚠️ Warning: Cleaning up the Themes system application data will reset all your personalizations to factory values. You will lose the settings saved in the application, but the theme files will remain in memory.
If nothing works, the only option is to re-install the app. APK-Themes file from a verified resource (e.g. APKMirror) and install it manually. Once installed, apply the classic theme immediately to reset the current changes.
Cleaning cache and residual themes files
Even after applying a standard theme, the phone may still have tails from previous designs, high-quality themes with live wallpaper and complex animations can take up hundreds of megabytes, and to fully clean these files, you need to find and delete them manually.
The theme files are stored in a hidden system directory. Using a file manager (e.g. MIUI File Manager or Total Commander), follow the path:
/MIUI/theme/It stores files with the.mtz extension. These are theme installation packages. You can safely delete any files in this folder, except those that are marked as system (usually they have specific names, such as default.mtz).
It is also worth checking the cache folder:
/MIUI/theme/cache/This directory stores temporary previews and downloaded resources. Cleaning this folder will free up space and speed up the theme menu. Don't be afraid to delete the contents of the cache folder - the system will create new files as needed.
Where can I find the hidden MIUI folder?
For deep cleaning, you can use the built-in Security tool. Open the Security → Cleanup app. The system will analyze the device and suggest removing the garbage, which often includes residual files from deleted themes and graphics shell cache.
Comparison of methods of deleting topics
The choice of method depends on your specific situation: whether the application is removed, whether there is access to settings or requires a deep memory cleanup. Below is a table to help you choose the best way for your case.
| Method | Difficulty | Efficiency | Risk of error |
|---|---|---|---|
| Through the Topics app | Low. | 100% | Minimum |
| Change of region | Low. | 50% | Absent. |
| Cleaning the application data | Medium | 90% | Medium. |
| Manual deletion of files | Tall. | 100% | High-pitched |
As you can see from the table, the first method is the best for most users, which ensures that system files are safe and that all parameters are reset correctly, and manual deletion of files is recommended only for experienced users who understand the structure of the Android file system.
If you use custom firmware (Pixel Experience, LineageOS) on your Redmi Note, the concept of MIUI theme does not work there, in such cases you need to remove the corresponding Magisk modules or launcher widgets, which requires a separate approach.
Problems after removal and their solution
Once you return to the standard theme, users sometimes encounter artifacts: missing icon signatures, changing the font size on the menu, or stopping Always On Display, which are solved by rebooting the interface.
The easiest way is to completely reboot the device, not just turn it off and on, but to reboot the power menu, it forces the system to read the configuration files again, and if that doesn't work, try changing the theme to any other one, and then return "Classic" again.
💡
If the widgets on the desktop are missing after removing the theme, try pressing the empty screen space for a long time and selecting “Add widgets” – perhaps the new theme just hid them or changed the desktop grid.
In rare cases, you may need to reset your launcher settings. Go to Settings → Apps → All Applications → System Launcher (or MIUI Launcher). Select Clean → Reset. This action will return the desktop icons to factory status, so all folders and widgets will be deleted.
⚠️ Warning: Resetting the launcher will remove all the folders you created on the desktop and the order of the icons. Use this method only if visual bugs critically interfere with the work.
If problems persist, check for system updates. Often bugs with themes are fixed in security patches. Go to Settings → About phone and click on MIUI/HyperOS to check for updates.
💡
Complete cleaning of the theme requires not only the application of the standard, but also checking folders with cache, and in difficult cases, resetting the launcher settings.
