Xiaomi smartphone owners often face the desire to personalize their device by installing third-party themes or fonts from the MIUI Themes store. However, visual design experiments do not always end successfully. Sometimes, after installing a new style, text becomes unreadable, some characters are replaced with squares or disappear altogether, making navigation on the menu impossible. This is especially true for the Redmi 9 model, where the factory shell can conflict with modified resources.
The problem can be different, from mild discomfort when reading to complete inoperability of the interface, when you can not read the names of menu items to return to the original state. Fortunately, the Android operating system with the shell MIUI has mechanisms to correct such situations. You do not need to be a programmer or carry the phone to the service center to fix the display of text.
In this article, we will take a look at all the available ways to return the regular font to the Xiaomi Redmi 9. We will look at the standard methods through settings, working with themes, as well as radical but effective methods of resetting if the interface has stopped responding to touch. It is critical not to panic and consistently follow the steps, since chaotic actions can lead to locking the device. Let's start with the simplest and safest methods of solving the problem.
Analysis of the reasons for changing the text
Before we start active recovery, we need to understand what caused the failure. In the vast majority of cases, the culprit is the user who accidentally or intentionally activated a third-party resource. MIUI allows you to replace system font files, which is a powerful customization tool, but carries risks.
Often users download themes from unverified sources or use older versions of themes that are not optimized for the current version of Android. Version conflict leads to the fact that the glyph table (character set) does not have codes for certain letters or emojis, as a result, instead of text, you see empty squares or chaotic characters.
- 🔍 Install a third-party theme that forcibly changes the system font without the possibility of a quick rollback.
- 🔍 Using the “Fonts” function in the “Themes” application with downloading files from third-party stores.
- 🔍 Failure of the system process com.miui.themes after the firmware update.
- 🔍 Attempting to implement fonts through root rights or modified recovery menus.
Also, you should consider that some launcher apps can intercept font control. If you recently installed a new launcher, the problem may be in its settings. However, if the distortion is visible in all menus, including the lock screen and settings, then it is the system font file.
Resetting settings through the “Themes” app
The first and logical step is to try to get everything back through the regular Themes app. Even if the text on the screen is hard to read, try to navigate by the icons. The standard app icon looks like a color brush or a package labeled Themes.
You need to get into a user profile. This is usually a little person icon in the bottom right or the top corner of the screen. Once you log in, find the item that's responsible for your purchases or downloads. In MIUI, it's often marked by a person icon or a list, and it stores the history of all the topics you've applied.
☑️ Algorithm of actions in the app Topics
If you can't find a Classic theme on the list, try to find a theme called Default or Untitled. Often the system theme is hidden in the back of the list. If the interface allows you to read text at all, look for the Remove or Reset button next to the active theme. Once the theme is reset, the system will automatically tighten the standard font resources.
⚠️ Warning: If the changes are not effective immediately after applying a standard theme, be sure to fully restart the device by pressing the power button. Sometimes the font cache is updated only after a cold start of the system.
Use of safety mode for discharge
If the interface is so distorted that you can’t get into the settings or theme app, Safe Mode will come to the rescue.In this mode, the Xiaomi Redmi 9 only loads with factory settings and standard fonts, ignoring all custom themes and third-party apps.
To enter Safe Mode on Redmi 9, you need to press the power button before the turn off menu appears. When the Turn Off icon (or Reboot, depending on the version of MIUI) appears on the screen, press it and hold your finger for a few seconds. The system will ask for confirmation of the transition to Safe Mode.
Once confirmed, the phone will restart, and in the corner of the screen you will see the words "Safe Mode" in which all third-party fonts must automatically turn off and the text will return to the factory view. Now you can safely go to the settings and delete the problematic theme or application that caused the conflict.
- 🛡️ Safe mode disables all third-party launchers and design themes.
- 🛡️ In this mode, you can remove applications that block the normal operation of the system.
- 🛡️ To get out of safe mode, simply restart the phone in the usual way.
💡
If the touch screen reacts poorly due to font distortion, try connecting USB-mouse-wise OTG-This will allow you to precisely click on the right menu items to enter Safe Mode.
Forced reset via Recovery Mode
In situations where the software methods through the interface do not work, you have to resort to more serious measures. Recovery mode allows you to interact with the system at a low level, where graphical themes are not loaded, but use the basic font of the bootloader.
To enter recovery mode on Xiaomi Redmi 9, you need to turn off the phone completely. Then simultaneously press the Volume Up and Power buttons. Hold them until the Mi logo appears, then release the power button, continue to keep the volume. You will see a menu with English text, where the navigation is carried out by volume buttons and the choice by the power button.
| Action on the menu | Description of function | Risk of data loss |
|---|---|---|
| Reboot | Simple reboot of the device | No. |
| Wipe Data | Full reset to factory settings | Tall (removes everything) |
| Connect with MIAssistant | Connecting to a PC for firmware | Depends on the action. |
| Safe Mode | Download in Safe Mode (if available) | No. |
You have to choose Wipe Data, then Wipe All Data. This action will completely delete all your files, photos and contacts, but it is guaranteed to return the phone to a store-like state with a standard font. If your goal is only to save readability, and data is more important, try first just select Reboot, sometimes it resets the font cache.
⚠️ Note: Wipe All Data is irreversible. If you don't have a backup in the Google or Mi Cloud cloud, you will lose all your personal data.
What to do if the volume buttons do not work?
Delete conflict files through file manager
If you have access to the file system, for example, through a connection to a computer in file transfer mode or through an embedded Explorer (if it reads), you can try to delete specific font files. In Android, fonts are stored in certain ways, and deleting them causes the system to recreate default copies.
You need to find the /MIUI/theme or /data/fonts folder. The exact path may vary depending on the MIUI version, but often custom fonts are in the /MIUI/theme/custom directory. Find files with the.mtz extension or font files and delete them. After deleting, reboot the device.
This method requires caution, as deleting system files can lead to a cyclical restart (bootloop).If you are not sure about your actions, it is better to use the method of full reset via Recovery described above.
- 📁 The path to fonts is often hidden in system folders that require special rights.
- 📁 Deleting the font file can lead to its automatic replacement with the standard one when restarting.
- 📁 Make sure to back up the deleted files to your computer before cleaning.
Prevention and display setting
Once you have managed to return the standard font to Xiaomi Redmi 9, it is important to consolidate the success and prevent the situation from recurring.The system allows you to flexibly adjust the size and style of text without setting third-party themes. Go to Settings → Screen → Text Size.
Here you can choose one of the preset sizes that will be comfortable for your eyes.Using system settings ensures that the font will remain readable in all applications, including bank clients and messengers, which may not display modified fonts correctly.
💡
Use only official themes from the high-rated Popular themes section to avoid font conflicts in the future.
It is also recommended to update the Themes app regularly through the GetApps store or Google Play. Xiaomi developers are constantly fixing bugs in the font rendering engine, and the current version of the application minimizes the risk of character encoding problems.
