Why are Xiaomi’s standard fonts not good for users?
Xiaomi’s MIUI-based smartphones offer a wide range of visual settings, but standard fonts are often criticized. Some users have character sizes in MIUI 14+ automatically scaled depending on system applications, creating dissonance in the interface. Others don’t like the too “childish” design of Mi Sans fonts (especially in versions for the global market), and others face the problem of displaying Cyrillic in some third-party fonts. In this article, we will discuss all the current ways of changing fonts, from official themes to manual implementation through ADB.
It's important to understand that the ability to change fonts depends on the firmware version and device model. For example, on the POCO F5 with HyperOS, the application algorithm for the theme differs from the Redmi Note 12 on MIUI 13. We tested all methods on current devices (2022-2026 release) and specified the limitations for each method.
Method 1: Official MIUI Topics (Safeest Method)
The easiest and most recommended way is to use a built-in theme gallery. Xiaomi offers dozens of free and paid themes with unique fonts that apply to the entire interface.
How it works:
- 📱 Open the “Themes” app (icon with a brush on your desktop).
- 🔍 In the search bar, enter the query: "font" or "font" (in English results more).
- 🎨 Select your favorite theme and click "Apply". The font will change automatically for system applications.
- 💰 Note: Some items require purchase (price usually 1-3).$).
Limitations of the method:
- ⚠️ The font will only apply to system applications (Settings, Phone, Messages) on WhatsApp, Telegram or games, it will remain the same.
- ⚠️ After updating MIUI The topic may be reset to standard.
| Xiaomi model | Support for changing fonts through themes | Notes |
|---|---|---|
| Redmi Note 12/13 | ✅ Complete. | Including dynamic fonts (scroll animation) |
| POCO F5/X5 | ✅ Partial | Some topics are blocked due to regional restrictions |
| Mi 11/12/13 | ✅ Complete. | Support for fonts with 3D effect |
| Redmi 10A/9A | ⚠️ Limited. | Only basic fonts without animations |
Method 2: Manually add fonts through the file system (without root)
If the theme gallery doesn’t have a suitable option, you can manually download a.ttf or.otf font. This method works on most devices with MIUI 12–14 and HyperOS, but requires a PC connection.
Step-by-step:
- Download your favorite font from trusted sources (e.g. Google Fonts) and recommend the.ttf format, which is better compatible with MIUI.
- Connect your smartphone to your computer via USB and turn on the "File Transfer" mode.
- Copy the font file to /sdcard/MIUI/theme/.cache/fonts/ If the folder is not available, create it manually.
- Reboot the device. The new font will appear in the theme settings.

Warnings:
⚠️ Note: Some fonts may contain malicious code. Check the file with VirusTotal before installing, especially fonts from sites like "fontspace.com" or "dafont.com" where users upload their work.
⚠️ Note: On HyperOS devices (e.g. Xiaomi 14), this method may not work due to the changed folder structure. ADB (described below).
Method 3: Using ADB to change font (for advanced ones)
If previous methods didn’t work, you can apply the font through Android Debug Bridge (ADB), a semi-official way that doesn’t require root, but involves working with the command line.
What you need:
- 🖥️ A computer with installed Xiaomi drivers and ADB Tools.
- 📱 Smartphone with enabled debugging USB (Settings → The phone. → Version. MIUI — Press 7 times, then return to Settings → Additionally. → For developers).
- 💾 A.ttf font file rebranded as DroidSansFallback.ttf (this is important!).
Instructions:
- Connect the phone to your PC and type in the command line: Adb devices Make sure the device is defined.
- Copy the font to the system folder: adb push DroidSansFallback.ttf /sdcard/
- Transfer the file to the system section: adb shell su mount -o rw,remount /system cp /sdcard/DroidSansFallback.ttf /system/fonts/ chmod 644 /system/fonts/DroidSansFallback.ttf reboot
💡
If the su command is not working, then root access is disabled on your device. Try using an alternative method with the Magisk module (described in Method 4).
The result: After the reboot, the font will change across all apps, including Chrome and Instagram.
- 🔄 After updating MIUI font may be dropped.
- 🚨 Wrong teams ADB This can lead to bootloop (a looped load).
Method 4: Magisk modules for complete font control
For users with an unlocked bootloader and installed Magisk, modules are available that allow you to change fonts at the system level.
- 🔧 FontManager supports over 500 fonts, including Google Sans and Product Sans.
- 🎯 MiuiFontChanger – a dedicated module for Xiaomi, runs even on HyperOS.
- 🖋️ iFont – allows you to install fonts directly from the application (requires Magisk).
How to determine:
- Download the module in.zip format with XDA Developers.
- Open Magisk Manager and go to the Modules section.
- Click "Install from storage" and select the downloaded file.
- Reset the device.
What if the phone does not boot after installing the module?
Advantages of the method:
- ✅ It works on all applications, including games.
- ✅ Support for dynamic fonts (change in thickness in real time).
- ✅ The ability to roll back to the standard font in one click.
Method 5: Third-party applications (for non-systemic changes)
If you only need to change the font in certain applications (like VK or Twitter), you can use specialized utilities. They don't change the system font, but they overlay their style on top of the interface.
Top.-3 applications:
- 📲 FontFix – runs without root, but requires Android 10+.
- 🎨 HiFont - more than 1000 fonts, supports Cyrillic.
- 🔤 Fontoid – allows you to create your own combination of fonts.

- Select the font and click "Apply".
- Activate the special features service for the application (instructions will appear on the screen).
⚠️ Note: These applications may conflict with MIUI Optimization is a built-in Xiaomi service that manages performance. If after applying the font, the phone starts to slow down, turn off optimization in the developer settings (Settings) → Additionally. → For developers → Shut down. MIUI Optimization).

| Problem. | Reason. | Decision |
|---|---|---|
| Font reset after update | MIUI overwrites system files | Re-apply the theme or use the Magisk module |
| Hieroglyphs instead of Cyrillic | Font does not support Russian language | Download the font version marked "Cyrillic" |
| The app doesn't change the font | The app uses its own rendering engine | Try Magisk or ADB-method |
| The phone overheats after changing the font | The conflict with MIUI Optimization | Turn off optimization in the developer settings |
If none of the methods worked, check:
- 📋 Version MIUI HyperOS (some builds block font change).
- 🔒 Antivirus – it can block the installation of third-party fonts.
- 📡 Internet connection stability (for downloading topics).
💡
On HyperOS devices (such as Xiaomi 14 or Redmi K70), standard font swap methods may not work. In this case, use ADB or Magisk modules, but pre-back up via Settings → Memory → Backup.
