How to put a system font on Xiaomi

Changing the standard font on Xiaomi smartphones is one of the easiest and most effective ways to personalize the device’s interface. Unlike many other manufacturers, the company offers users flexible tools to change the typography without having to obtain superuser rights, which allows you to make the screen unique, improve readability of text or simply refresh the appearance of the MIUI or HyperOS shell.

There are several proven methods to achieve this goal, ranging from the official theme store to complex manipulation of system files through ADB. The choice of a particular method depends on your smartphone model, Android version and desired degree of customization. In this article, we will discuss all the current options in detail so that you can choose the most suitable for your case.

Official method through the "Themes" app

The safest and most recommended way to change the font is to use the built-in Themes app, which is pre-installed on all Xiaomi, Redmi and Poco devices, and provides full compatibility with system elements, ensuring that icons, settings menus and dialog boxes are displayed correctly.

To get started, you need to start the app and go to the bottom menu by selecting the Profile tab (human icon), and here is the Font button, which opens the catalog of available options. Some of them are free, others require payment or subscription Mi VIP. After choosing your favorite style, just click the Download button and then Apply.

It is worth noting that in some regions (such as Russia or India), the directory may be restricted due to licensing agreements, in which case changing the region in the smartphone settings to India or Singapore will help, which often expands the list of available content without losing data.

• 🎨 A huge selection: thousands of design fonts from independent authors from around the world.
• 🛡️ Security: no risk of system files being damaged or interface errors.
• 🔄 Ease of return: you can roll back to the standard Mi Sans or Mi Font font at any time.
• 🌐 Regional Features: Content availability may vary depending on the region selected.

⚠️ Note: When using paid fonts, make sure your Mi Account is linked to a valid payment method, otherwise the application may not work.

Once you use the font, the system will automatically restart the GUI, and you will notice changes in all applications, including messages, contacts, and the browser. If you don't like the result, repeat the path in the Themes app and select another option or click Reset.

Use of hidden codes and third-party stores

If the standard directory seems too boring or limited to you, there are alternative sources. One popular method is to use the code ##855## or #8558###, which opens a hidden font testing menu. However, on newer versions of MIUI 13 and 14, as well as HyperOS, this method is often blocked by developers.

A more efficient way is to install third-party theme stores, such as GetApps (the official Xiaomi store for some regions) or modified versions of Theme Editor, which allow you to download.mtz font files directly, bypassing geographical restrictions.

To install a font from a.mtz file, you will need the MIUI Theme Editor app or its analogues. The process is as follows: download the font file from a trusted source (for example, a 4PDA forum or Telegram channels), open it through the editor and select an application option. The system can request installation confirmation from an unknown source.

• 📂 Format MTZ: native Xiaomi theme archive format containing graphics and fonts.
• 🔓 Bypassing locks: the ability to install fonts that are not officially available in your region.
• 📱 Compatibility: Not all third-party fonts are correctly displayed on new versions of Android.
• ⚙️ Additional settings: some editors allow you to change the size and saturation of the font.

It is important to understand that installing unverified files can lead to unstable interface performance. Always check author ratings and comments from other users before downloading.

💡

Before installing a third-party font, take a screenshot of the current display settings to know which settings have been changed if problems arise.

Advanced installation through file manager

For users who want full control, there is a method of manually replacing files through a file manager, which does not require root rights, but does not work on all models due to the security limitations of Android 11, 12 and higher, the essence of the method is to rename the font file and place it in a special system folder.

First, you need to download the font file in.ttf or.otf. Then rename it to MiFont.ttf (or MiFont.otf). After that, you need to move the file to the root of internal memory or to the MIUI/theme folder, if it exists. On some devices, simply put the file in the root of memory and apply it through the font selection menu.

Accommodation path (if available):


/storage/emulated/0/MIUI/theme/com.android.thememanager/

If the simple method didn't work, you could try backing up your current theme, unpacking it, replacing the font file inside the archive, and reassembling it, but this process requires accuracy and understanding the structure of MIUI files.

Adjusting font size and boldness

Beyond style, readability is critical. Xiaomi allows you to flexibly adjust the size and boldness of text, which is especially true for users with low vision or for devices with high resolution screens, where standard text may seem too small.

You can find these settings by Settings → Screen → Text Size. Scaling sliders are available here. Also, the Additional Settings menu often features the Fat Text option, which forcefully makes all characters more saturated, improving contrast.

You don't need to set maximum font sizes unnecessarily, because this can disrupt the layout in some applications, where interface elements will bump into each other, and it's best to size the text so that it reads comfortably, but doesn't take up the entire screen.

• 👁️ Reading comfort: The right size reduces eye fatigue with prolonged use.
• 📐 Adaptability: Some apps ignore system font size settings.
• 🔋 Battery impact: Using bold print could theoretically slightly increase power consumption AMOLED-screen.
• 📏 Pixel density: on high-density screens (PPI) The standard size may be too small.

Experiment with settings to find a balance between aesthetics and functionality, remember that font is the main tool for interacting with information on a smartphone.

Solving Cyrillic and Coding Problems

One of the most common problems when installing custom fonts on Xiaomi is the lack of support for Cyrillic. Many beautiful fonts are created by Western designers and contain only the Latin alphabet. When installing such a font, all Russian text becomes a set of incomprehensible characters or squares.

To avoid this situation, always check the font description before downloading. Look for Cyrillic, Russian or Multi-language marks. If you use third-party sources, make sure the file contains a full set of glyphs for Russian.

In case you have already installed the font and the phone is unreadable, don't panic. Xiaomi's system usually has a built-in timeout: if you don't confirm the action within 15 seconds, the settings are reset. If the screen is locked, try entering Safe Mode by pressing the off button and selecting the appropriate option, or use the voice assistant to return the settings.

⚠️ Note: If after installing the font, the phone goes into a cyclic restart (bootloop), you must boot into Recovery Mode and perform a reset (Wipe Data), saving important data beforehand, if possible.

Use of Google Fonts (for advanced fonts)

For those who don't find the perfect one in MIUI, there's a Google Fonts library, and there are thousands of quality fonts available for free, but just downloading them to your phone isn't enough, you have to adapt them to MIUI.

There are dedicated online converters and converter apps (like FontFix or web services to create.mtz from.ttf). You download a.ttf file from Google Fonts, the service wraps it into a Xiaomi theme structure, and you get a ready-made file to install.

This method allows you to use popular fonts like Roboto, Open Sans, Montserrat or Comfortaa, while maintaining the stability of the system, the main thing is to monitor the license of the font, although most of them are free for personal use.

💡

Using proven converters for Google Fonts is the best way to get a unique design without the risk of system breakdown.
