1.Official method: changing the font through MIUI themes

2. Hidden settings: MIUI Lab for power users
If there are few built-in fonts, you can activate the hidden functions of MIUI Lab. This method allows you to install.ttf font files manually without root rights, but requires you to enable developer mode and work with ADB.

4. Font replacement via Magisk (for advanced)
If you're ready for a deeper setup, you can replace the system font with Magisk and FontManager, which gives you complete control over the typography, but requires an unlocked bootloader and a Magisk installed.

💡
Using Magisk to replace the font is the most flexible method, but also the riskiest. It is only suitable for users with experience with custom firmware and backups.
5 Manual editing of system files (experts only)
This method involves direct replacement of font files in the system partition /system/fonts. It requires root rights and access to the system partition (for example, through TWRP or ADB root access).
🚨 Warning: Mistakes can cause the system to fail.This method is recommended only for the recovery of standard fonts after unsuccessful experiments or for experienced users who understand the consequences.
# Example of commands to replace font through ADB root access:
adb shell
su
mount -o rw,remount /system
cp /sdcard/Download/yourfont.ttf /system/fonts/Roboto-Regular.ttf
chmod 644 /system/fonts/Roboto-Regular.ttf
reboot📌 Important nuances:
- Always backup original fonts (cp) /system/fonts /sdcard/fonts_backup).
