The visual component of a smartphone plays no less a role than its performance, because it is the screen we look at the most time. Standard system font can seem too small, pale or just boring, which is especially noticeable on quality. AMOLED-The Redmi Note 9 is a display. Thankfully, the shell MIUI, The Android operating system in Xiaomi devices provides users with ample opportunities for customizing the interface, including replacing the font headset.
The text style change procedure does not require superuser rights or complex device reprogramming. All the necessary tools are already built into the system or available through the company's official services. In this guide, we will discuss in detail the standard methods of replacing fonts, consider installing third-party headsets through the theme store and answer frequently asked questions about displaying Cyrillic.
Before we make any changes, it’s worth noting that choosing a typeface that’s too complex or decorative can have a negative impact on the readability of small text in the settings menu. In addition, some third-party headsets may not contain a full set of characters, which will lead to “squares” instead of letters in apps or banking services.
Use of built-in MIUI font settings
The safest and fastest way to change the look of text is to use the standard system functionality. In Xiaomi devices, the Font component is responsible for this, which is integrated directly into the settings menu, which ensures that the chosen style will be correctly displayed in all system applications and will not cause conflicts with the interface.
To access the settings, you need to open the main menu and find the gear icon. Next, the path will look like this: Settings → Screen → Font. In some versions of the firmware, the path may be slightly different and located in the Settings → Device → All settings → Font, if the system suggests downloading the component on the first start.
In the window that opens, you'll see a list of pre-installed options that you can switch with a single click, which usually includes classic MIUI font, a more rounded Roboto and sometimes a few stylized options, and after selecting a new option, the system will ask you to confirm the action and automatically apply the changes after a few seconds, rebooting the graphical interface.
⚠️ Warning: If after selecting a new font, the interface becomes unreadable or artifacts appear, don't panic. Just go back to the same settings menu and select the standard font. MIUI Or Systemic to Reset Changes.
It's important to understand that the built-in set of headsets is limited to basic options. If you're looking for something that's truly unique or specific to a particular task, there may not be enough regular tools, but for most users who just want to zoom in or make text more contrasting, there are plenty of built-in options.
Installation of fonts through the “Themes” app
If you don't like the standard set of options, the official Theme app, which is preinstalled on every Xiaomi smartphone, is a powerful customization tool that allows you to download thousands of custom and professional designs, including individual font packages, and this is where you can find rare headsets that support Cyrillic.
To get started, start the Themes app and switch to the Font tab (usually located in the bottom menu or in the Profile → Font category). In the search bar, you can enter the name of the desired font, for example, Roboto, Comfortaa or simply query Cyrillic to find options that support Russian.
The installation process takes seconds. Once you click Download and then Apply, the system will make changes to the display registry. Unlike manual file installation, the theme store method automatically checks the compatibility of the headset with your version of MIUI, which reduces the risk of errors.
- 🔍 Open the Topics app and go to the search section.
- 📥 Enter a font name or keyword, such as "Bold" or "Handwritten".
- ✅ Press the download button, wait for the process to end and select "Apply".
- 🔄 If the system requests a reboot to correctly display changes in some applications, agree.
It is worth noting that some fonts in the store may be paid or require you to view ads to activate, and there are regional restrictions: in the global version of the firmware, the font set may differ from the Chinese version. If the desired font is not located, try changing the region in the phone settings to India or Singapore, which often expands the available content in the theme store.
☑️ Checking before installing font
Manual installation of third-party fonts
For advanced users who have not found the right option in the official store, there is the possibility of manual installation of files in the format.mtz. Such files can be found on specialized forums or sites with themes for MIUI. This method gives full control over the appearance of the system, but requires more care when choosing the source of files.
After downloading the font file, you need to place it in the root of internal memory or in the MIUI/theme folder. Then in the Topic application, you need to go to the Profile → My Themes → Fonts (or click on the folder icon in the upper right corner, if it is available in your version), which will display a list of local files ready to install.
Special attention should be paid to file extension. The system only recognizes the.mtz format. If you downloaded the.zip or.rar archive, it must first be unpacked. In some cases, it may be necessary to rename the file so that the system correctly identifies it as a font, rather than as a whole theme.
| Parameter | Description | Impact on the system |
|---|---|---|
| Format.mtz | Native theme format Xiaomi | Full compatibility, stable operation |
| Format.ttf/.otf | Standard Android fonts | Requires conversion or root rights to install |
| File size | Usually 100 Kb to 5 MB | Large files can load the interface more slowly |
| Support for coding | Presence of UTF-8 symbols | Critical for displaying Russian language |
⚠️ Note: Only download font files from trusted sources..mtz files can contain executable code that could potentially damage the system, although the risk is minimal when using official forums.
If the font did not apply after manual installation or a black screen appeared, press the volume and power button for a forced reboot. In safe mode (boot with a clamped volume button), the system often resets third-party themes to standard ones, which will allow you to return access to the menu.
Setting the size and fat content of the text
Often the problem is not the style of the letters, but the size or saturation. With the Redmi Note 9, you can flexibly adjust these settings to improve ergonomics, and this is especially true for people with low vision or who often use their phone in bright sunlight.
You can change the font size through the Settings menu → Screen → Text size. As you move the slider, you'll see in real time how the text displays in the preview. Increasing the font size automatically rearranges the interface grid, making elements larger and easier to press.
Another feature worth mentioning is the feature Enlarged Text, which is in the special features section. It allows you to make a font even more than a standard slider, but it can break the layout in some applications, where text will go beyond the buttons.
- 📏 Adjust the text size gradually to get used to the new scale.
- 🌗 Use the "Contrast Text" mode in special features if the standard font is not readable in the background.
- 👁️ Enable "Augmenter" if you need to temporarily review small text without changing system settings.

Problems with displaying Cyrillic and quadratic
One of the most common problems when installing third-party fonts on Xiaomi is the lack of support for Cyrillic. Since many popular headsets are created by Western designers, they may not have Russian alphabet symbols, resulting in the user seeing empty squares or question marks instead of letters.
To avoid this situation, always check the font description before downloading. The Xiaomi theme store often has a Cyrillic tag or examples of text in Russian. If you download a file from the Internet, open a preview or readme file and make sure that there are Russian letters there.
If the squares are already installed, don't worry. It doesn't mean that the system is damaged. Just go back to the font settings and select any standard option, and then all the characters will fall into place. In some cases, cleaning the cache of the Theme application through the application management menu helps.
⚠️ Warning: Don't try to "fix" the squared font by editing system files without root rights. This can lead to a cyclic bootloop. It's easier and safer to replace the font back with the system.
There are also universal stub fonts that replace missing characters with standard system ones. MIUI This mechanism doesn't always work properly, so you shouldn't rely on it. UTF-8.

To do this, just go to the Settings menu → Screen → Font or open the Themes app, go to the profile and select the Font section. There will be a button “Reset” or a font option called Default / MIUI. After it is used, the phone will return to its original appearance.
In rare cases, when the interface is not working properly even after changing the font, you may need to clean the data of the Themes application itself. → Annexes → All applications → Topics → Memory. → Clear the data. This action will remove the downloaded themes, but return the stability of the interface.
- 🔄 Select a standard font MIUI In the screen settings for instant return.
- 🗑️ Clear the cache of the "Themes" application if glitches (glitches) graphics are observed.
