How to put a font on Xiaomi: 5 ways to MIUI and HyperOS

Changing the font on Xiaomi smartphones is one of the most popular ways to personalize the interface. Standard system fonts in MIUI and HyperOS often seem too simple or inconvenient for users, especially on high-resolution screens. Fortunately, the manufacturer provides several official and informal methods of changing fonts, from built-in themes to manually installing.ttf files.

In this article, we will discuss all the current methods, including the nuances for different versions of firmware. You will learn how to install the font through Themes, ADB, third-party applications and even without root rights. Special attention will be paid to security – incorrect installation of fonts can lead to system failures or “bricking” of the device. All instructions are tested on the Redmi Note 12, Xiaomi 13 and POCO F5 models with the latest updates in 2026.

1.Official method: changing the font through the Topics

The easiest and safest method is to use the built-in Themes app. Xiaomi regularly adds new fonts to the official directory, many of them free.This method works on all devices with MIUI 12+ and HyperOS, does not require administrator rights and does not affect the warranty.

To change the font through the Topics:

• 📱 Open the Themes app (icon with brush on desktop).
• 🔍 Go to the Font section (in some versions) MIUI It's hidden behind the button. → Fonts).
• 🎨 Choose your favorite font from the collection. Popular options: Mi Sans, Roboto, SF Pro.
• 💾 Click Apply and Confirm Action. The system will automatically update the text display in all applications.

Please note: some fonts in the Topics are marked as VIP — You will need to install the Mi Account Premium (from 99).₽/Also, some fonts only support Latin or Chinese characters - check the description before installing.

2. Install font through ADB (no root)

If the built-in fonts aren’t enough, you can install your own.ttf file via ADB (Android Debug Bridge), a method that works on most Xiaomi devices with MIUI 13/14 and HyperOS, but requires you to enable USB Debugging and connect to a computer.

Step-by-step:

1. Download and install ADB Tools on PC.
2. Activate Developer Mode on your smartphone: go to Settings → About Phone and click on MIUI Version 7 times.
3. Enable USB debugging in Settings → Additional → For developers.
4. Connect your phone to your PC and execute the command in the terminal: Adb devices Make sure the device is identified (should appear its serial number).
5. Download your favorite font in.ttf format (for example, with Google Fonts) and rename it to custom_font.ttf.
6. Place the file in a folder with ADB and execute the commands: adb push custom_font.ttf /sdcard/ adb shell su mount -o rw,remount /system cp /sdcard/custom_font.ttf /system/fonts/ chmod 644 /system/fonts/custom_font.ttf reboot

If it is not available, check the correct file name and path (/system/fonts/ must exist).

3. Use of third-party applications (with risks)

Google Play has some type-change apps like iFont or FontFix, which make it easier, but they have limitations:

• ⚠️ Require root rights for full-fledged work (without them, the font will change only in some applications).
• 🔄 They may conflict with MIUI Optimization – System process responsible for performance.
• 📛 Some apps contain ads or collect data (check permissions before installing).

If you choose to use this software:

1. Download iFont from Google Play.
2. Select a font from the directory or download your.ttf.
3. Click Set and follow the instructions. The app will prompt you to activate the font through Themes or ADB.

4. Manual font change via TWRP (for advanced)

For users with an unlocked bootloader and TWRP installed, a method of replacing fonts through custom recovery is available. This allows you to install the font directly to the system partition, bypassing the limitations of MIUI.

Algorithm of action:

1. Download the font archive for Xiaomi (e.g., from the XDA forum). Look for themes marked [MIUI] or [HyperOS].
2. Place the archive (.zip) on a memory card or internal memory.
3. Reboot to TWRP (press Power + Vol Up when you turn on).
4. Select Install → Select archive → Swipe to Confirm Flash
5. After installation, run Wipe Dalvik/Cache and restart.

⚠️ Warning: An improperly assembled font archive can lead to a bootloop ( looped reboot).Before installing, check the reviews of a particular file on the forum and backup through TWRP (Backup → System).

5. Features for HyperOS

HyperOS is Xiaomi's new firmware, replacing MIUI in 2026, and it has changed the way you work with fonts:

• 🔄 The Font Directory in Themes is now synced with your Mi Account account – the installed fonts will be saved after resetting.
• 🛠️ Support for dynamic fonts that automatically adjust to the screen size.
• ⚠️ HyperOS has blocked the installation of fonts through ADB without unlocking the bootloader – this method only works on devices with unlocked BL.

For HyperOS, we recommend:

1. Use only official fonts from the Tomes.
2. When manually installed, check font compatibility with Android 14 (HyperOS base).
3. After upgrading from MIUI to HyperOS, reset the font to standard (Mi Sans) to avoid interface glitches.

💡

HyperOS has a feature called Adaptive Font, which automatically increases the boldness of text in bright light. It is included in Settings → Screen → Text and Scale.

6. Solving problems after changing font

If you have problems after installing a new font, use these tips:

Problem 1: Text is displayed in squares or characters.

• 🔍 Reason: Font does not support Cyrillic or special characters.
• 🛠️ Solution: Install a font with full Unicode support (e.g. Noto Sans).

Problem 2: After the MIUI/HyperOS update, the font reset.

• 🔍 Reason: System Update overwrote files to /system/fonts/.
• 🛠️ Solution: Repeat installation through ADB or TWRP.

Problem 3: Applications (e.g., banking) are not running.

• 🔍 Reason: Some applications check the integrity of system files.
• 🛠️ Solution: Return the standard font or add the app to exceptions MIUI Optimization (Settings) → Annexes → Application management → Threefold → Special access → Optimization MIUI).

💡

If the phone stopped turning on (bootloop) after changing the font, try booting into Safe Mode (press Power + Vol Down when turned on) and returning the standard font via ADB.
