Smartphones Xiaomi, running on the shell MIUI or new HyperOS, provide users with ample opportunities to personalize the visual component. One of the most requested features is changing the text display. This may be required for various reasons: from the banal desire to stand out among friends to the urgent need to improve readability for people with low vision.
The process of text modification affects several levels of the system. You can change it yourself, adjust it, or even completely change the interface. It is important to understand that standard Android settings allow you to do a lot, but deep customization sometimes requires third-party tools. font, adjust it size or even change completely language interface. It's important to understand that standard Android settings allow you to do a lot, but deep customization sometimes requires third-party tools.
In this article we will analyze in detail all the available methods, from simple switches in the menu to advanced ways to install custom styles. You will learn how to avoid common mistakes that can lead to an unreadable interface, and how to get everything back if the experiment fails.
Adjusting font size and style in the menu
The easiest and safest way to change the perception of text on the screen is to use the system's built-in tools. The developers Xiaomi have provided a convenient slider for adjusting the size of symbols. To access these settings, you need to go to the section Settings, then select the item Screen and find the subsection Text size.
Here you will see scale with the letter "A" of different sizes. As you move the slider, you instantly see changes in real time. Increasing the text size automatically adjusts the number of lines on the screen, which may affect the layout of some applications. Reducing the size allows you to fit more information on one screen, which is useful for working with documents or long lists of contacts.
In addition to size, a choice of style is often available in the same menu if additional themes are already installed on the phone. The standard font Roboto or corporate Mi Sans can be replaced with more decorative options downloaded from the theme store. However, it is worth remembering that complex ornate styles can impair the readability of small text in the interface.
Before installing a complex decorative font, check how it is displayed in frequently used applications, for example, in instant messengers or a browser.
Installing new fonts through the Themes application
For For those for whom the standard set is not enough, the company has integrated a powerful customization tool - the application. This is the official content store where you can find thousands of free and paid fonts. To start searching, open the application Xiaomi integrated a powerful customization tool - application Themes. This is the official content store where you can find thousands of free and paid fonts. To start searching, open the application Themes on your desktop and go to the tab Fonts in the bottom menu.
Catalog offers filters by category: handwritten, monospace, bold or minimalist styles. After selecting the option you like, click the download button, and then Apply. The system will automatically replace the system font in all supported applications. The process takes a few seconds and does not require rebooting the device.
However, not all fonts from the theme store support full Cyrillic. Some authors create styles only for Latin or Chinese characters. In this case, Russian letters may be displayed in a standard font, creating dissonance in the text. Always check the preview with Russian text before installing.
- 🎨 Open the application Themes and select the font category.
- 🔍 Use keyword search, for example, "Cyrillic" or "handwritten".
- ✅ Be sure to check the display of Russian letters in the preview before downloading.
- ⚙️ Apply the font and restart the Launcher to completely update the interface.
Changing the system language and regional settings
Changing text also implies changing the interface language. This is useful when purchasing a phone from China where the default language is Chinese, or if you want to practice a foreign language. Global versions MIUI and HyperOS support dozens of languages, switching between them occurs in the menu Advanced settings → Language and input.
In the list of languages you can select the desired option, and the system will instantly rebuild all menus, notifications and system messages. If the language you need is not in the default list, sometimes changing the region helps. Go to Settings → Advanced → Region and select the country where the desired language is spoken. This action may open additional language packs for download.
It is worth considering that changing the language affects the keyboard layout and voice input. After changing the system language, it is recommended to check the settings of the keyboard Gboard or built-in keyboard Xiaomito add the appropriate layout. Otherwise, you will be able to read the menu, but will not be able to type in the new language.
⚠️ Attention: When changing the region, some pre-installed applications may change their set of functions in accordance with the local legislation of the selected country.
Advanced configuration through the engineering menu and ADB
For users who want to get full control over displaying text, there are methods that go beyond the standard menu. Using debugging by ADB (Android Debug Bridge) allows you to change the screen density (DPI), which actually changes the size of all interface elements, including text, more radically than a regular slider.
To do this, you need to activate developer mode by clicking seven times on the build number in the menu About the phone. Then in the menu For developers enable USB debugging. Once you connect your phone to your computer, you can enter a command to change the pixel density. This requires caution, as too high a DPI value may make the interface unusable.
adb shell wm density 480In this command, the number 480 indicates the pixel density. The standard value for most smartphones ranges from 400 to 440. Increasing this number reduces the size of the elements, decreasing it increases it. This method affects the entire system globally, including icons and padding, so before using it is advisable to write down the current value.
How to return the standard screen density?
If the interface has become too small or large, use the adb shell wm density reset command to reset the settings to factory values.
Solving problems with display of characters (squares)
A frequent problem when installing third-party fonts is the appearance of “squares” or empty rectangles instead of letters. This means that the selected font file does not contain glyphs (graphic styles) for certain characters, most often for Cyrillic or special characters. The system tries to display the character, but does not find it in the file.
To correct the situation, you must immediately return to the standard font. Go to the application Themes, go to the user profile (person icon) and select the tab Fonts. There will be an item Default font or Classic. Click Applyto restore the system.
Sometimes the problem occurs after a system update, when the new font becomes incompatible with the updated version Android. In such cases, clearing the Themes application cache or completely resetting font settings through the recovery menu helps if the phone boots in safe mode.
| Change method | Complexity | Impact on the system | Risk of errors |
|---|---|---|---|
| Size slider | Low | Character size only | Minimum |
| Theme Store | Medium | Style of all labels | Medium (squares) |
| ADB commands | High | Scale of the entire interface | High |
| Change language | Low | Menu and notification text | Minimum |
Using ADB commands gives maximum flexibility, but requires precise knowledge of the current device parameters so as not to disrupt the interface layout.
Features of fonts in different versions of MIUI and HyperOS
Shells Xiaomi are constantly evolving, and the approach to typography changes with each major update. In earlier versions MIUI users had more free access to system font files, which made it possible to replace them manually through file managers with root access. In modern versions, especially with the transition to HyperOS, system protection has increased.
Now the installation of fonts that are not certified in the Theme Store can be blocked by the security system. An attempt to embed a third-party file through a file manager often results in an installation error. This is done to ensure stability and uniformity of the interface, but limits customization options for advanced users. .mtz third-party production through a file manager often leads to an installation error. This is done to ensure stability and uniformity of the interface, but limits customization options for advanced users.
However, the enthusiast community is finding workarounds. There are special modified versions of the Themes application or scripts that allow you to install any fonts. However, the use of such tools requires unlocking the bootloader and may lead to loss of warranty for the device.
⚠️ Attention: The interface and names of menu items may vary slightly depending on the firmware version (CN, Global, EEA) and the specific smartphone model.
