How to change font to Xiaomi Redmi 9: 4 proven ways (including hidden ones)

Xiaomi Redmi 9 with factory-made MIUI firmware offers users the flexibility to customize the interface, including changing the font. However, not everyone knows that in addition to standard themes, there are alternative methods in the Mi Theme Store - from manually importing fonts through ADB to using third-party launchers. In this article, we will analyze all the current ways to change the font, their pros and cons, and also tell you how to return everything if something goes wrong.

It is important to understand that the process depends on the version of MIUI and the status of unlocking the bootloader. On global firmware (for example, MIUI Global 12.5+), some of the features may be limited, while on Chinese or custom (such as Xiaomi.eu) advanced settings are available. We tested all methods on Redmi 9 with MIUI 14 - valid for 2026.

1. Standard method: changing the font through MIUI themes

The easiest and safest method is to use a built-in theme store, which does not require root rights or technical skills, but the choice of fonts is limited to official collections.

How it works:

• 📱 Open the Themes app (icon with brush on desktop).
• 🔍 In the search bar, enter “font” or “font” (in English layout).
• 🎨 Select your favorite theme from the Fonts section. Pay attention to the rating and the number of downloads - this will help to avoid low-quality packages.
• ⬇️ Click Apply and confirm download. The system will automatically install the font and reboot the interface.

Advantages of the method: security (no risk of damaging the system), simplicity (even for beginners), automatic font updates. Disadvantages: limited choice (many fonts are paid) and regional restrictions (on global firmware some topics may not be available).

2. Installation of fonts through APK-files without root)

If there are few embedded fonts, you can install third-party fonts via.apk files. This method works on most versions of MIUI, but caution is needed: not all fonts are compatible with Redmi 9, and some may contain ads or malicious code.

Step-by-step:

1. Download a.apk font file from a trusted source (like FontSpace or DaFont). Avoid sites with suspicious domains like.xyz or.top.
2. Transfer the file to your phone (for example, via Telegram or Google Drive).
3. Install the file as a regular application. If the system blocks the installation, allow installation from unknown sources in Settings → Applications → Special Access → Install unknown applications.
4. Once installed, open the font app and click Apply. If no buttons are available, use the iFont app (available on Google Play).

Attention! Some fonts may not support Cyrillic or special characters. Check compatibility in the file description before installing. If the text is displayed in characters after using the font, return the standard font through Settings → Display → Font.

3. Manual font change via ADB (for advanced)

This method is suitable for those who are willing to work with ADB (Android Debug Bridge allows you to install any TTF/OTF-fonts, but requires the developer mode enabled and the connection to the PC.

What you need:

• 💻 Computer with installed ADB Tools.
• 🔌 USB-cable (preferably original).
• 📁 Font in.ttf or.otf format (for example, Inter or Fira Code).
• 🔧 Developer mode on the phone (Settings) → The phone. → Version. MIUI — press 7 times).

Instructions:

1. Connect Redmi 9 to your PC and allow debugging over USB.
2. Open the command prompt (cmd) in the ADB folder and execute: Adb devices Make sure the device is defined.
3. Copy the font to the system folder: adb push your font.ttf /sdcard/
4. Move the font to the system partition (root or unlocked bootloader rights required): adb shell su mount -o rw,remount /system cp /sdcard/your font.ttf /system/fonts/ chmod 644 /system/fonts/your font.ttf reboot

Critical information: On global MIUI firmware without an unlocked bootloader, this method will not work - the system will block changes in the /system/fonts/ folder. Alternative: use Magisk and the FontManager module.

4.Use of third-party launchers for local font change

If you only need to change the font on your desktop (not the entire system), install an alternative launcher.

• 🎨 Nova Launcher – Supports custom fonts through the Nova Google Companion plugin.
• 🔧 Action Launcher – allows you to customize fonts for icons and widgets.
• 📱 Microsoft Launcher – Integration with Office Fonts (e.g. Calibri).

How to apply:

1. Install a launcher from Google Play.
2. Upload the.ttf font to your phone.
3. In the launcher settings, find the “Fonts” or “Styles” section and specify the path to the file.
4. Restart the launcher (usually swipe down on the desktop is enough).

💡

If the font is not used, try renaming the file to Latin (without spaces and Cyrillic) - some launchers incorrectly process encoding.

The method limitation is that the font will only change in the launcher interface, and in system applications (Settings, Phone) will remain standard, but this is the most secure way, not requiring root rights.

5. Restore standard font after failures

If after experimenting with fonts the text began to be displayed incorrectly (squares, hieroglyphs, lack of Cyrillic), return the standard settings:

⚠️ If, after the manipulation, the ADB The phone stopped turning on, don't try to reset settings through Recovery - this can make the problem worse. Instead, run the original firmware through the Mi Flash Tool with the Clean All option.

6. Frequent mistakes and how to avoid them

Even when following the instructions, users face typical problems.

• ❌ Font is not applied after installation APK Reason: font file is corrupted or incompatible with MIUI. Solution: Download the font from another source (e.g. Google Fonts).
• ❌ ADB Error read-only file system Reason: section /system Solution: unlock the bootloader or use Magisk.
• ❌ Emojis are missing after the font change Reason: some fonts don't support Unicode characters Solution: install a separate emoji package via iFont.

⚠️ Attention, Redmi! 9 firmware MIUI Global version 13.0.4+ Blocking the installation of fonts through ADB without unlocking the bootloader. TWRP and manual partitioning /system.

💡

Before any typeface manipulation, back up the system through Settings → Additional → Backup. This will quickly roll back if you make errors.
