Xiaomi’s fonts are not just a design element, but part of the visual experience that shapes the perception of the interface. Standard system fonts in MIUI often seem too mundane or inconvenient for users, especially on high-resolution screens. Fortunately, the manufacturer provides several ways to replace them, from built-in tools to advanced techniques for enthusiasts.
In this article, we will discuss all the current methods of changing the font on Xiaomi, Redmi and POCO devices running MIUI 12/13/14 and HyperOS. You will learn how to use official themes, third-party applications, as well as low-level tools like ADB - taking into account all the nuances and potential risks.
1.Official method: changing the font through MIUI themes
The easiest and safest method is to use the built-in MIUI Themes store, which does not require root rights or technical skills, but has a limitation: only fonts approved by Xiaomi are available. However, the range is regularly updated, and options include both minimalist Sans Serif and decorative handwriting sets.
To change the font through the themes:
- 📱 Open the Themes app (icon with brush on desktop).
- 🔍 Go to the Fonts section in the lower menu.
- 👆 Scroll through the list of available fonts or search for keywords (e.g., “bold” for bold or “handwritten” for handwritten).
- 🎨 Click on the font you like, then select Apply. The system will automatically update the text display in all standard applications.
Important: some fonts may be paid (the cost usually does not exceed 50-100 rubles). Also note that after changing the topic, the font may reset - in this case, it will have to be used again. To check the compatibility of the font with your version of MIUI, pay attention to the reviews of other users in the the theme card.
2. Third-party applications: Magisk and font replacement modules
If you don't have enough built-in fonts in MIUI Themes, you can use third-party solutions. The most reliable method is installing the Magisk module (root rights required).
- 🔧 iFont allows you to download.ttf and.otf fonts directly from your device. Supports preview and backup.
- 🎯 FontFix – a dedicated module for Xiaomi that bypasses the limitations MIUI system-based.
- 🖥️ ZFont is a universal solution with a database of more than 1000 fonts, including Cyrillic fonts.
The installation process through Magisk:
- Download a module (e.g. FontFix.zip) and save it to internal memory.
- Open Magisk Manager, go to Modules and click Install from Storage.
- Select the downloaded file and confirm the installation. Once rebooted, the fonts will be available in the module settings.
💡
Before installing the module, back up the system partition via TWRP or Magisk, which will help restore the device if the font is not compatible with your version of MIUI.
⚠️ Note: Using informal fonts may cause text display failures in some applications (e.g., bank clients or instant messengers.
3. Replace fonts through ADB (no root)
For users who don’t want root rights but are willing to work with ADB, there is a command line method for replacing fonts, which works on most Xiaomi devices running MIUI 12-14, but requires USB debugging.
Instructions:
- Download and install ADB Tools on your PC (e.g. Google’s Platform Tools).
- Connect your smartphone to your computer and allow debugging (in the developer settings, turn on USB debugging).
- Download the font in.ttf and rename it Roboto-Regular.ttf (or another system font you want to replace).
- Open the command line in the folder with ADB and execute: adb push Roboto-Regular.ttf /sdcard/ adb shell su mount -o rw,remount /system cp /sdcard/Roboto-Regular.ttf /system/fonts/ chmod 644 /system/fonts/Roboto-Regular.ttf reboot
Critical: Incorrectly replacing system fonts can lead to a “bootloop” before executing commands, make sure the font file name matches the original system file.

4. Manual editing of system files (for advanced)
This method is only suitable for users with root rights and experience with the Android file system. It allows you to replace fonts at the system file level, but requires caution: an error can lead to an inoperability of the interface.
Algorithm of action:
- Using a root-enabled file manager (such as Root Explorer) go to /system/fonts/.
- Make a backup of the original fonts (copy them on the SD-map).
- Replace your target files (e.g. NotoSansCJK-Regular.ttf for Chinese characters or Roboto-Bold.ttf) with your fonts. Make sure the file names match!
- Change the permissions on the replaced files: chmod 644 /system/fonts/*.ttf
- Reset the device.
⚠️ Note: Some fonts in the /system/fonts/ For example, deleting or damaging DroidSansFallback.ttf can cause the interface to crash. Always check the font compatibility with your version. MIUI forum-like 4PDA.
5. Limitations and problems when changing fonts on new MIUI versions
Starting with MIUI 13 and HyperOS, Xiaomi tightened control over system files, making it harder to replace fonts.
| MIUI version | Limitation | Bypass |
|---|---|---|
| MIUI 12 | Replacing fonts with ADB works without root | Standard Adb push commands |
| MIUI 13–14 | /system/fonts/ is protected from recording | Magisk or patch boot.img is required |
| HyperOS | Blocking changes in the system section | Only official themes or modules signed by Xiaomi |
On HyperOS devices (such as Xiaomi 14 or Redmi Note 13), it is almost impossible to replace fonts without official themes. The manufacturer closed most of the "rooks" for modifying system files, focusing on security, in which case the only legal option is to use fonts from MIUI Themes or wait for the release of specialized modules for the new OS.
If customization is critical, consider alternative firmware like LineageOS or Pixel Experience, where there are no font restrictions, but this will require unlocking the bootloader and losing warranty.
Download Platform Tools from Google’s official website
Enable debugging over USB in the developer settings
Make a backup copy of the original fonts
Check font compatibility with MIUI on forums
Prepare a team for rollback in case of failure

6.Alternative solutions: Launchers and customization applications
If you can't replace the system font, you can go around the way of using launchers or apps that support your own fonts.
- 🌈 Nova Launcher + Nova Google Companion plugin – allows you to set fonts for icons and widgets.
- 📱 Action Launcher – supports customization of fonts in folders and shortcuts.
- 🎨 Substratum (requires root) – a thematic font engine for individual applications.
These solutions don't change the system font globally, but they allow you to customize the most visible interface elements. For example, in Nova Launcher, you can set a separate font for folder names, which will visually transform the desktop.
For instant messengers (such as Telegram or WhatsApp), there are separate themes with customized fonts, which can be found in chat settings or through third-party repositories like Telegram Themes.
7. Frequent mistakes and how to avoid them
When replacing fonts, users often face typical problems, and here are the most common ones and how to solve them:
- 🔄 Font does not apply after rebooting – check file access rights (chmod) 644) and the correctness of the ways in /system/fonts/.
- 📵 Characteristics instead of text - the font does not support Cyrillic. Download the version with advanced encoding (for example, Noto Sans with Cyrillic support).
- 🚫 Apps are getting stained — some banking apps (like SberBank Online) are blocking the work on modified systems. Use Magisk Hide or roll back to standard font.
- 🔍 The font looks blurry - the problem is wrong DPI Try calibrating the pixel density in the developer settings.
If the font is replaced, return the original files from the backup. In some cases, cleaning the system cache helps (Settings → Memory → Clear cache).
💡
Before any typeface manipulation, create a full backup system via TWRP or Mi PC Suite. This is the only way to guarantee that your device will work again if it crashes.
