You can change the font to Xiaomi Redmi 9 through standard MIUI settings and using third-party tools - but not all methods are equally safe. Budget smartphone 2020 release is still popular, but its firmware has limitations: for example, in the latest versions of MIUI 12.5+ disappeared the section "Themes" with the ability to select fonts. In this article, we will analyze all the current methods - from official to "advanced" requiring root rights.
It's important to understand that changing system fonts can affect how some applications (especially banking ones) display text or cause interface artifacts. We tested each method on Redmi 9 with MIUI 11-14 firmware and identified those that work consistently. If you just want the original look of text, you have enough standard settings. If you want exclusive design, you have to use workarounds.
1. Official method: MIUI settings (without root)
The easiest and safest method is to use the built-in MIUI options. Unfortunately, in newer firmware versions (MIUI 12.5 and above), the font section is hidden, but it can be returned via "Themes." Here's how to do it:
- Open the "Themes" (the icon on the desktop or in the application menu).
- Go to the Profile section β Settings β Fonts.
- Choose one of the suggested styles (e.g. MiSans, Roboto or SF Pro).
- Click "Apply" and confirm the changes.
If you don't have a Fonts section, your version of MIUI doesn't support it. In this case, try updating your firmware to the latest stable version via Settings β About Phone β System Update. Alternative path (for older versions):
Settings β Additional β Language and input β Fontπ‘
If some apps display text incorrectly after changing the font, reboot the phone. This will reset the text rendering cache.
Please note: official fonts do not support Cyrillic in some styles (for example, MiSans Thin may display Russian letters incorrectly).
2. Use of MIUI themes (alternative method)
If you don't have a Fonts section in your settings, you can set the font through custom themes. Many MIUI themes include not only wallpaper and icons, but also custom fonts. Here's how it works:
- π² Open the Topics app and go to the Online section.
- π In the search bar, enter the query: font Cyrillic or font russian.
- π¨ Choose your favorite theme (pay attention to the rating and number of downloads).
- π₯ Click "Download" and then "Apply".
The disadvantage of this method is that the font will only change for system elements, and in most applications will remain standard.In addition, some topics may contain advertising or collect data (especially little-known).
| Title of the topic | Author | Cyrillic support | Features |
|---|---|---|---|
| Minimal OS 14 | Xiaomi Official | Yes. | Clean sans serif font, optimized for MIUI 14 |
| Pixel Font Pack | Google Port | Partially. | Fonts from Android 13, but Russian characters can be displayed curved |
| Samsung One UI | MIUI Themes | Yes. | Samsung font imitation, supports all languages |
3. Installation of fonts through the application "iFont" (without root)
iFont allows custom fonts to be installed without superuser rights, but with restrictions. On Redmi 9, it only works on MIUI 11-12 firmware (newer versions require bypassing locks).
Download APK from the official website (not from the Play Market)
Enable installation from unknown sources (Settings β Applications β Special access)
Download the font in.ttf or.otf format
Backup your current settings (Settings β Additional β Backup)
-->
- Install iFont (download only from official source!).
- Download your favorite font (for example, from DaFont or Fontsquirrel sites) and save it to the Download folder.
- Open iFont, click Local and select the downloaded file.
- Click Set β the application will prompt you to apply the font through MIUI Theme Editor.
- Confirm the change and restart the phone.
β οΈ Attention: MIUI 13/14 This method may not work because of Xiaomi's limitations, and then you'll have a "Font installation failed" error. ADB-Teams (described in the following section).
iFont has the advantage of previewing fonts and supporting Cyrillic, but some users complain about the interface lag after installing heavy fonts (such as decorative elements). If you notice brakes, return the standard font through the same iFont.
4. Change font through ADB (for power users)
If previous methods didnβt work, you can apply the font through Android Debug Bridge (ADB). It's a semi-official way that doesn't require root rights, but requires command line. MIUI.
You'll need:
- π» A computer with installed Xiaomi drivers and ADB Tools.
- π± Included debugging by USB (Settings β The phone. β Version. MIUI β Press 7 times, then return to Additional β For developers β Debugging by USB).
- π₯οΈ Font in.ttf format, renamed Roboto-Regular.ttf (this is important!).
Instructions:
- Connect Redmi 9 to your computer and allow debugging.
- Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with ADB.
- Follow the commands in turn: adb devices (should display your device's serial number) adb shell su -c "mount -o rw,remount /system" exit adb push Roboto-Regular.ttf /system/fonts/ adb reboot
β οΈ Attention: Misuse of the right ADB If the phone doesn't turn on after rebooting, try resetting it with Recovery Mode. + Volume Up when switched on).
What if the ADB canβt see the device?
This method replaces the Roboto system font, so all applications will use the new style. However, some banking programs (such as SberBank Online or Tinkoff) can block work on βmodifiedβ devices.
5. Installation of fonts with root rights (maximum customization)
If you have root access (for example, through Magisk), the font customization options are expanded many times over.
- π€ Install fonts for individual applications.
- π¨ Change the style of the font in Recovery Mode.
- π Create backup copies of original fonts.
The most reliable tool for this is Fontster (available in the Magisk repository).
- Open Magisk Manager and go to the Modules section.
- Click + β Download from the network and find Fontster.
- Install the module and restart the phone.
- After the reboot, open Fontster from the app menu.
- Select a font from the list or upload your own (.ttf or.otf).
The advantages of Fontster:
- π Support for multiple fonts at the same time (you can assign different styles to different applications).
- π Automatic backup of original fonts.
- π οΈ Restore Standard Fonts in One Click.
β οΈ Note: Installing Magisk modules may result in loss of warranty and SafetyNet issues (Google Pay, some banking apps will not work). YASNAC.

Root access gives you maximum customization freedom, but it's not guaranteed, and it can disrupt secure applications, and only use it if you're prepared for the consequences.
6. Solving problems after changing font
Even if you've done it right, you can get bugs when you change the font, and here are the most common problems and solutions.
| Problem. | Reason. | Decision |
|---|---|---|
| Text in the applications is displayed in squares | The font does not support Cyrillic. | Return the standard font or choose another (with support of Russian) |
| Interface brakes when scrolling | Too "heavy" typeface with decorative elements | Install a simpler font (such as Open Sans) |
| Some applications do not run | Banking applications detect system modification | Return the standard font or use MagiskHide |
| Font reset after the MIUI update | System update overwrites font files | Repeat the font installation procedure |
If the phone starts to overheat or discharge quickly after changing the font, this is a sign that the system is constantly redrawing the text.
- Return the standard font.
- Clear the cache in Settings β Applications β Application Management β System β Cache.
- Reset the device.
If none of these methods worked, your version of MIUI may have a very limited version, so you can either accept the standard font or consider flashing it to custom firmware (like LineageOS or Pixel Experience).
