UI personalization is not just a nice option, it's a way to make smartphone use really comfortable. Owner Xiaomi or Redmi gets a powerful customization tool that allows you to change the appearance of the system beyond recognition. One of the most popular features is the ability to change the system font, which affects the readability of menus, messages and applications.
The standard MIUI shell or the new HyperOS already offer a few options out of the box, but they are often not enough. Users may find that standard headsets are too small, fuzzy or simply boring. Fortunately, the Android ecosystem in conjunction with the services of the Chinese giant allows you to implement almost any typeface available on the network.
In this article, we will discuss in detail all the ways to replace fonts: from simple selection in settings to manually installing files of.mtz or.ttf formats. You will learn how to avoid problems with “knakosyabr” in the menu and how to return the standard look if the experiments went too far.
Standard font change capabilities in MIUI and HyperOS
The first and most obvious way is to use the built-in functionality of the system. Xiaomi engineers have provided a basic set of tools that allows you to quickly change the style of text without third-party software. ADB-team.
To access the settings, you need to follow the path: Settings → Screen → System Font. Here you will see a list of preinstalled options. Usually there are few and they are often targeted at the Chinese market, but among them you can find quite readable Latin and Cyrillic headsets.
However, if you don't have a standard set, it will suggest you go to the theme store, which is the main hub for downloading content, clicking on the "Online" button, you will be taken to the Themes directory, there are thousands of free and paid fonts available, and it's important to understand that not all of them support Cyrillic, so you better check the preview or description before using it.
💡
Before installing a new font, be sure to check whether it supports Cyrillic, otherwise, squares or question marks will appear instead of letters in the menu and messages.
The installation process is simple: you pick the option you like, you click on Free or Buy and then Apply. The system automatically reboots the interface and the new style takes effect. This is the safest method to guarantee the stability of Redmi or Poco.
Install third-party fonts through the FontFix app
If the built-in directory doesn’t meet your aesthetic needs, the popular FontFix app comes to the rescue.It’s a third-party tool that lets you install almost any typefaces found on the Internet, bypassing the limitations of the official theme store.
It doesn't always require superuser rights to run, but it's better to get them for full functionality. It automatically determines your device's model and suggests compatible options. APK-The file, the algorithm of actions is the following:
- 📲 Launch the application and select the Fonts tab to view the directory.
- 🔍 Find the desired font through search or in popular categories.
- ⬇️ Click the Download button to save the file to the device.
- 🛠 Select the installation method (usually “Auto” or “Auto «MIUI Font Installer»).
- ✅ Confirm the application and wait for the interface to restart.
In the settings of FontFix, you can choose "MIUI Font Installer", which is specially adapted for Xiaomi smartphones, and it creates a special configuration file that the system perceives as a legitimate system resource.
☑️ Checking before installing FontFix
It is worth noting that once the operating system is upgraded to new versions of Android 13/14, security algorithms can block the operation of such applications, in which case you will need to more deeply configure through ADB or use specialized modules.
Manual installation of MTZ and TTF fonts
For advanced users who want full control, manual installation is available..mtz is native to the MIUI shell, while.ttf is a standard font format found on a host of resources like Google Fonts or DaFont.
An application is often used to install.mtz files. MIUI Theme Editor or built-in Explorer with root rights. If you use.ttf, the process can be more complicated, as the system requires renaming the file to root. miui_font.ttf and put it in the system folder. /fonts. Doing it without a backup is dangerous.
| Parameter | MTZ format | TTF format | OTF format |
|---|---|---|---|
| Compatibility | High (MIUI) | Medium (requires conversion) | Low. |
| Installation | Through Themes/FontFix | Through root access. | Not supported |
| Security | Safe. | Risk of system error | High risk |
| Quality. | Optimized. | Depends on the file. | - |
When manually replacing system files, it is critical to follow the name syntax. Any typo in the file name can cause the phone to go to bootloop (cyclic reboot). Always have the original rollback font file on hand.

Using ADB for Advanced Customization
The ADB (Android Debug Bridge) method is considered one of the most reliable methods for installing fonts without root permissions, but it requires a computer, which allows you to implement fonts at the system level, bypassing some of the security limitations of MIUI.
First, you need to enable USB debugging in the Developer menu. Then connect your smartphone to your PC and execute a command to check the connection: adb devices. If the device appears in the list, you can proceed to file embedding.
The method is to replace the system font file with a push command. However, starting with MIUI 12 and above, the /system partition is often read-only. In such cases, a temporary replacement or overlay is used.
adb push my_custom_font.ttf /data/local/tmp/fonts/
adb shell pm grant com.example.fontapp android.permission.WRITE_SECURE_SETTINGSThis is only suitable for advanced users. An error in the syntax of a command or file can lead to unstable interface operation. Importantly, before any manipulation through the ADB, make sure to make a full backup of the data.
💡
ADB allows you to install fonts without root rights, but requires caution and follow the instructions accurately, as an error can lead to a software failure.
Problems with Cyrillic alphabet and their solution
One of the most common problems with changing fonts to Xiaomi is the lack of support for Cyrillic. Many beautiful fonts in global directories contain only Latin characters, which turns the system interface into a set of squares or question marks.
To avoid this, always check the font description for the phrase "Cyrillic support" or "Cyrillic support." If you install the font manually, open it in any text editor on your PC and check for Russian letters. If there are none, you can't use it as a system font.
There is a method of “substituting” characters, when Russian letters from another font are artificially added to the font without Cyrillic, but this requires work in graphic font editors (for example, FontForge) and a deep knowledge of typography.
How to return the default standard font
If you’re tired of experimenting with design or the new font is inconvenient to read, it can be easily reset, and in most cases, just go back to the Settings menu → Screen → System Font and select the first option on the list, which is usually called “Default” or “Default”.
If the interface is unresponsive or the font is applied globally and does not change through the settings, resetting the theme to the standard will help. Go to the Topic app, go to the profile (human icon) and select "Themes" There will be a "Standard" or "Classic" item that you need to apply.
If that doesn’t work (for example, when you manually replace system files), you may need to reset your phone settings. Before doing this, make sure that all important data is stored in the Mi Cloud or on your computer.
