Changing the look of a smartphone often starts with a desire to diversify the interface, but sometimes experiments lead to unpredictable results. Users who install a new font through the MIUI or HyperOS theme store often face the problem when the text becomes unreadable, cropped or simply ceases to like.
Xiaomi’s operating shells have a complex visual caching system, so simply switching the theme doesn’t always solve the problem instantly. In some cases, the system gets stuck on the erroneous display of characters, requiring deeper intervention in personalization settings. It’s important to understand that a standard font is not just a picture, but a system file on which the readability of the entire menu depends.
In this article, we will break down all the available ways to return the standard font on Xiaomi, Redmi and POCO devices. We will look at standard methods through settings, working with themes and more complex options for resetting through safe mode. Recovery of default font is a safe process if you perform actions consistently, without missing the steps of restarting the system.
Standard method of return through font settings
The most obvious and safe way to get back to the way you look is to use the built-in settings menu. In the MIUI shell and the new HyperOS, the developers have a direct path to managing typography. You don't need third-party apps or root rights, just go to the appropriate menu section.
To start, open the Settings app and find the Screen (or Display) option, select Font or Text Size and Font from the options list, and that's where the switch is, which allows you to activate the default system font, ignoring the modifications you've installed through the store.
Once you have selected the standard option, the system may need to reboot to apply the changes, which is normal, because the fonts are loaded into memory when the operating system starts, and if the text remains the same after the reboot, the theme may be active, which force the font to change.
💡
Switching to system font in screen settings is the first and most important step that solves 80% of text display problems.
Note that in some regions, the menu may be called a little differently, but the logic remains the same.Look for sections related to personalization or display. Mi Sans system font (or its counterpart depending on the Android version) is the most optimized for Xiaomi screens.
Theme management and reset to a standard theme
Often the problem is not the font itself, but the active theme of the design. Themes in the Themes store may contain embedded font files that take precedence over system settings. To return the old font, sometimes it is enough to reset the theme to a standard one.
Open the Themes app (tube icon) and go to the user profile, usually the little button in the lower right corner. Select the Topics section and find a theme called Classic, Default or No Theme, and using this theme will disable all visual modifications, including fonts.
- 🎨 Open the Topics app on the desktop.
- 👤 Go to the user profile (human icon).
- 📂 Select the Topics tab in the list of purchased or downloaded.
- ✅ Click on the Classic theme and select Apply.
If a standard theme doesn't appear in the list, try removing newly installed themes. The theme store has a feature to manage downloaded components. Removing custom font from the phone's memory can also force the system back to using the basic character set.
Why does the font not change after the topic changes?
It is important to note that some paid themes may have restrictions on deleting or modifying, in which case a full reset of the theme settings, which can be found in the settings menu of the theme application itself, helps.
Using Safe Mode for Diagnostics
If the phone’s interface has become so unreadable that you can’t find the menus you want, Safe Mode will come to the rescue.In this mode, Android only loads with system apps and standard settings, ignoring all third-party themes and fonts.
To enter safe mode on most Xiaomi smartphones, you need to press the power button, and then hold the Turn Off (or Reboot) button on the screen for a long time until the prompt to go to Safe Mode appears. After confirmation, the phone will restart, and the corresponding inscription will appear in the corner of the screen.
In Safe Mode, you'll see a standard font that confirms that the problem is in third-party software or theme. While in this mode, you can safely remove the problematic theme or app that caused the crash. Once deleted, just restart your phone as normal.
⚠️ Warning: Some features, such as fingerprints or desktop widgets, won't work in Safe Mode. Don't worry, this is the standard behavior of the diagnostic system.
Breaking out of Safe Mode is the normal restart of the device. Just press the power button and select Reboot or Turn off. The system will return to normal operation, but without problematic files if you have managed to delete them.
Resetting the settings of the "Themes" application and cleaning the cache
Sometimes font files get stuck in the cache of the system application that handles the themes. Even if you change the theme, the old font can be downloaded from temporary storage. Clearing the cache and data of the Themes app helps solve this problem.
Go to Settings → Applications → All Apps. Find the Themes app in the list. Click on it and select Memory. Here you need to click Clear Cache and, if that doesn't help, Clear Everything (or Reset).
Settings → Applications → All Applications → Themes → Memory → Clean EverythingOnce the data is cleared, the theme app will go back to the box-like state, and you'll have to re-select the theme, but that ensures that there's no hidden font settings left, and that's one of the most effective ways if other methods don't work.
| Action. | Impact on data | Need for a reset |
|---|---|---|
| Change of font on the menu | Secure, data is stored | Desired. |
| Resetting theme to Classic | Drops wallpaper and icons | Not necessarily. |
| Cleaning the data of the application Topics | Remove downloaded themes from memory | Required. |
| Safe regime | Temporarily disable functions | Entry and exit required |
Keep in mind that cleaning the Themes app data will remove all the themes you downloaded from your local storage, but it won’t remove them from your Xiaomi Cloud account.
Problems with custom fonts and file formats
Users often try to install fonts manually by downloading files with the.mtz or.ttf extension from unverified sources, which may not be compatible with the Android or MIUI version, resulting in "quadatics" or empty spaces instead of letters.
If you have manually installed a third-party font and it has broken the system, you can only return the old font by deleting this file. Go to Files → Internal Memory → MIUI → theme. Find the folder with the name of the installed font and delete it, or rename it so that the system cannot read it.
☑️ Checking font compatibility
Some fonts require superuser (Root) rights to be installed in the /system/fonts system folder. If you don't have a deep knowledge of Android modification, it's best not to use such methods. An error when replacing a system file can lead to a cyclic reboot.
⚠️ Note: Installation of fonts from unknown sources may contain malicious code or cause unstable interface. Use only proven themes from the official store.
If the phone is already in bootlooping because of the font, only logging into Recovery mode and resetting data (Wipe Data) will help. This is an extreme measure that will delete all data from the phone, so back up regularly.
Specificity of fonts in HyperOS and new versions of MIUI
With the release of the HyperOS shell, Xiaomi introduced a new system font, HyperOS Sans (or Mi Sans depending on the region), which is better readable on small screens and adaptable. To return the “old” font in the context of the new shell means to activate this system variant.
In newer versions of firmware, the personalization menu has become more flexible, so you can change not only the font, but also its boldness, as well as the header size separately from the main text, these settings are located in the additional section within the font menu.
If the font changed on its own after the system update, it is a planned update from the developers. To return the visual style of the old MIUI 12 or 13, you can only use a theme that mimics the old style, since the system font files are updated along with the firmware.
💡
Use the “Preview” feature in the theme store before installing to evaluate how the font will look on your screen without applying it fully.
For owners of flagship models, dynamic font change is available depending on the content, but it rarely affects system menus. The main way of controlling remains the same - through screen settings or the application of the default theme.
