How to remove the theme from the phone Xiaomi Poco X3: the complete guide

Owners of Xiaomi Poco X3 smartphones often face the desire to personalize the interface by installing third-party designs from the Themes catalog. However, the result does not always live up to expectations: fonts can become unreadable, and icons can merge with the background.

The process of returning to factory design depends on how the graphics shell was installed. If you just downloaded a file from a store, it takes a couple of minutes. It is much more complicated if you used modified packages or third-party launchers that introduce changes deeper into the system. In this article, we will analyze all possible scenarios, from simple switching to forced reset.

Don’t panic if the screen looks distorted or the menu is no longer available. The MIUI system that powers the Poco X3 has built-in protections to restore the interface to a critical environment, and the key is to follow the steps below consistently and not interrupt the process halfway through.

Standard removal through the Topics app

The most obvious and safest way to return to the standard look is to use the built-in design management tool, which requires you to open the Themes app (or Themes), which is the system component of the shell, and even if the current design looks strange, the application icon usually stays in place or in the Tools folder.

Once you start the app, you need to go to the user profile, and you can do this by clicking on the avatar or the person icon in the lower right corner of the screen, and this is where the history of all downloads and activated files is stored. Find the Topics section in the list and select the "Designs" or "My themes" option, where all installed packages are displayed.

In the list, find the default theme — usually called Classic, Default or Unlimited. Click on it and then select Apply. The system will automatically replace the current wallpaper, fonts and icons with factory ones. If you want to completely erase the downloaded file, find it in the Download list, click on the basket icon or select Delete from the control menu.

• 🎨 Open the Topics app and go to profile.
• 🔄 Find the standard Classic theme and click “Apply».
• 🗑️ Delete unnecessary files through the Downloaded menu».
• 📱 Restart the device for a full cache update.

It is important to understand that simply applying another theme does not always completely clear the cache of the previous one. Sometimes leftover graphics can be stored in memory, causing visual artifacts. Therefore, after changing the design, it is recommended to clean the cache of the Theme application through the settings of the smartphone.

Reset theme settings through the system menu

If the Themes interface is damaged or not opened due to conflicts, you can use the Poco X3 system settings. This method allows you to bypass the store's graphical shell and force reset display settings. Go to Settings and find the Themes or Wallpaper and personalization section.

Within this menu, it often hides the ability to reset all the changes made to the visual style. Look for the option “Reset theme” or “Restore by default.” This feature forcefully activates the standard MIUI package, ignoring the current settings of third-party files, which is especially useful if the phone starts to work slower after installing a new design.

⚠️ Note: Resetting through the system menu may not delete the theme file itself from memory, but only deactivate it. To completely clean the space, you still need to go to the storage and delete the file manually.

Another hidden way is to use the interface settings recovery mode. Press the power button, but instead of turning off or rebooting, look for the UI reset option in the menu (if available). On some versions of Poco firmware, this works by long-term pressing on the "Off" item on the lock screen, which causes a safe mode menu where the themes do not load.

💡

If the settings menu doesn’t open due to a theme crash, try running the phone in Safe Mode by holding the off button on the lock screen to access the system.

Use of safe mode for removal

When a theme is installed causing critical errors, blocking access to menus, or rendering the phone unusable, Safe Mode comes to the rescue. In this mode, the Poco X3 only loads with system applications, ignoring all third-party themes and launchers, which is the perfect way to remove malicious or conflicting design.

To enter Safe Mode on Xiaomi Poco X3, press and hold the power button until the turn off menu appears. Then press and hold your finger on the Turn off icon on the screen. A request to go to Safe Mode will appear - confirm the action. The phone will reboot, and in the corner of the screen you will see the corresponding inscription.

While in Safe Mode, you can safely log into settings, remove a problematic theme through the Themes app, or even remove a third-party launcher if the problem is there. Once you remove the source of the problem, simply restart the phone in the usual way and it will return to normal mode.

• 🛡️ Press the “Switch Off” icon to enter Safe Mode.
• 📂 Delete problematic files through file manager.
• 🔄 Reboot the device to exit debugging mode.

It's worth noting that in safe mode, some features may not be available and the Internet will not work. This is normal behavior for the system to diagnose. Don't try to install new applications in this mode, as this can lead to unpredictable results.

Forced data dumping and clean-up

If the soft methods don't work, you'll have to resort to more radical measures. Cleaning up the Topic app data allows you to reset it to factory status, which often solves the problem of a stuck theme. To do this, go to Settings → Apps → All Apps.

In the list, find the Themes app. Click on it and select Clean → Clear Everything (or Clear Data). This action will delete all cached data and design settings, returning the theme to default. Be careful: it will also remove your favorite themes from the recent list within the app.

As a last resort, if the theme is so deeply embedded that it interferes with the system, you may need to completely reset your phone to the factory settings (Hard Reset).Be sure to back up all important data before doing this, as this step will delete all the contents of the internal memory of the Poco X3.

Removal of third-party launchers

Users often confuse the theme with a third-party launcher installed, such as Nova Launcher, Microsoft Launcher or Apex. These apps completely replace the desktop, notification panel and application menu. To remove such a “theme”, you need to remove the launcher application itself.

Go to Settings → Apps → All Apps. Find the suspicious app you installed to change the look. Click Delete. If the button is inactive, the launcher may have been granted device administrator privileges. In that case, go to Settings → Password and Security → Device administrators and uncheck the application.

⚠️ Warning: After removing the third-party launcher, the system can temporarily display the standard error interface until the first reboot.Don't be afraid if the icons "go" - just restart the smartphone.

After removing the third-party launcher, the Poco X3 system will automatically return to using the standard POCO Launcher or MIUI Launcher. If this does not happen, go to Settings → Home Screen and select the default system launcher.

Recovery through Computer (ADB)

For advanced users whose phone has turned into a “brick” because of the theme, there is a method of removing through a computer using a tool. ADB (Android Debug Bridge. This way you can delete system packages for themes that are not deleted through the interface, USB-cable and on-debugging USB phone-on.

Connect Poco X3 to your computer and type in a command to search for a theme package. Usually, commands look like searching for packages with the name com.android.thememanager or third-party theme names.

adb shell pm uninstall --user 0 name.packet.topics

Using this method requires caution: Removing critical system components can make it impossible to boot the operating system, and use this method only if you know exactly which package is causing the problem and have experience with the command line.

• 💻 Connect your phone to a PC with installed ADB.
• 🔍 Find the name of the package through the command adb shell pm list packages.
• ❌ Execute the removal command for a specific package.

This method is particularly effective for removing preset themes that the manufacturer does not allow to remove in the usual way, or for cleaning the remnants of remote applications that continue to affect the system.

💡

Using ADB is a powerful tool for removing system themes, but requires accuracy, as a bug in the packet name can disrupt the interface.
