Xiaomi smartphone owners often experiment with the look of the interface by installing custom fonts through the built-in Themes app. However, sometimes this leads to the text becoming unreadable, individual characters disappearing or the interface looks incorrect. Especially relevant is the question of how to reset the font on Xiaomi Redmi 9A if after installing a new theme the phone stopped displaying text in Russian or appeared in the menu “squares”.
Fortunately, the MIUI operating system that runs your smartphone has several ways to go back to the factory settings of text display. You don't have to have super-user rights or be a programming expert to fix the situation. Most of the time, the problem is solved in a couple of minutes through the standard settings menu.
In this article, we will take a look at all possible methods, from simple theme switching in the application to a complete system reset, how to delete conflicting files, why a standard font can disappear from the list, and what hidden MIUI features will help restore the readability of the interface without losing personal data.
Why the font became unreadable or disappeared on Redmi 9A
Before you start taking action, it's important to understand why the crash is happening. Most often, the problem is that third-party themes are not working properly. When you download a theme from MIUI Themes, it replaces the system font files. If the theme was created for another version of Android or contains coding errors, Redmi 9A will not be able to render the text correctly.
Another common reason is manual import of font files. Users often download archives from the Internet and try to install them through the Download Font menu. If the file is corrupted or not adapted to the screen resolution of your device, the system can freeze or display crankshares. Conflict of MIUI versions also plays a role: system updates sometimes break compatibility with old themes.
Sometimes a failure occurs after a failed firmware update, in which case system font files can be corrupted or replaced with default ones that do not support Cyrillic in the selected region, and understanding the source of the problem will help you choose the right recovery method.
Method 1: Return the standard font through the Topics app
The easiest and safest method, which works 90% of the time, is to use the standard Themes app, and even if the interface is partially unreadable, the navigation of the main sections is usually saved, and you have to force the design style to be system.
Open the Topic app (an icon with a brush or a "T"). In the lower right corner, look for the Profile button (usually a person icon). In the menu that opens, select the Fonts section. This will show a list of available options, including the one that is currently active. Find the item called Classic or Standard (standard) and click "Apply" button.
If the standard font does not appear in the Locals list, go to the Store or Review tab inside the app. Search for Classic or Default. Download the official font from Xiaomi and install it. After application, the system may require the device to restart to display the changes correctly.
☑️ Checking before changing font
It's important to note that after you use a standard font, the interface may not be updated instantly. Give the system 10-15 seconds to redraw the elements. If the text is left unreadable after you reboot, move on to the following methods.
Method 2: Removing third-party design themes
If a simple change of font didn’t help, the problem may lie deeper in the design theme itself, which controls not only fonts but also icons, sounds and system windows, in which case you need to completely remove the active theme, returning the default style of MIUI.
Go to the Topic app and go to your profile. Select the Topics section. You'll see a list of all the designs you've downloaded. Find a theme that's marked as "Used" or "Active." Click on it and select the Remove or Reset option.
After removing the theme, the system will automatically switch to the standard design, which also clears the GUI cache. If the theme menu does not open due to text inaccuracy, try the next method with cleaning the application data.
⚠️ Attention: Deleting the theme can change the appearance of icons and widgets on the desktop. Don't worry, this is normal system behavior when returning to factory interface settings.

Method 3: Cleaning the data of the “Themes” and “Wallpaper” application
Sometimes font configuration files are corrupted at the application cache level, in which case forced clearing of the data of the system services responsible for visualization helps, this method is safe for your personal photos, contacts and applications.
Go to Settings → Applications → All Apps. In the list, find the Themes app. Click on it and select Clean → Clear Everything (or “Reset”). The same must be done for Wallpapers and System UI if this option is available.
Once you do this, the phone can act as if you turned it on for the first time, and you have to re-choose the language, the time, and connect to Wi-Fi, which means that the reset was successful, and the fonts will return to factory status.
| Action. | Where to find out. | The result |
|---|---|---|
| Clearing the Tham cache | Settings → Applications → Topics | Deletion of temporary font files |
| Data resetting by Thames | Settings → Applications → Topics → Clean up everything | Full return of the theme settings to factory |
| Cleaning the Wallpaper | Settings → Applications → Wallpaper | Resetting the lock screen settings |
| Reboot. | Power button | Application of changes in the system |
💡
Before cleaning system application data, make sure you have a backup copy of important settings, although personal files (photos, videos) will not be affected.
Method 4: Reset all phone settings (Hard Reset)
If none of the above methods helped to return the readable font to Redmi 9A, the damage may have affected the system files deeper, in which case the radical but effective method remains - a complete reset to a factory state.
Important: This step will remove all data from the phone’s internal memory: contacts, SMS, installed apps and photos. Be sure to back up important information before starting the procedure.
To perform the reset, go to Settings → About Phone → Reset (or Advanced Settings → Recover and Reset). Select Erase All Data. The system will request confirmation and input of the unlock password. Once confirmed, the phone will restart and begin the cleanup process, which can take 5-10 minutes.
⚠️ Warning: Make sure the battery level is at least 50%. Interrupting the reset process due to battery discharge can lead to malfunction of the software and the inability to turn on the phone.
💡
Hard Reset is a guaranteed way to fix any font software errors, but it requires the complete deletion of user data.
How to Set a Safe Font After Resetting
Once you have managed to reset the font to Xiaomi Redmi 9A and return the standard display, you want to personalize the device again. To avoid a recurrence of the problem, you should adhere to certain rules when choosing a new design.
First, use only the official MIUI theme store. Avoid installing fonts from unverified sources through file managers. Second, pay attention to the theme rating and downloads. Popular themes are usually tested for compatibility with different models.
Third, check the preview before you use it, if the subject description says it only supports English or Chinese, don't install it if you use the Russian interface, and there are special fonts marked Cyrillic that guarantee the correct display of Cyrillic.
- 📱 Choose high-rated themes (4.5 stars and above) from the official store.
- 🔍 Look for the “Cyrillic Support” label or check the screenshots in the description.
- 🚫 Avoid importing font files (.mtz) from questionable sources on the internet.
- 💾 Backup your system before installing heavy graphics themes.
