Xiaomi Redmi 10 owners often face the desire to personalize their smartphone interface, and changing the font is one of the first steps to a unique look. Standard MIUI system fonts can seem boring or inconvenient, especially with prolonged use of the device. Fortunately, the manufacturer has provided several ways to modify the text display, from basic settings to customization.
In this article, we will discuss all the current methods of changing the font on Redmi 10, including official MIUI tools, third-party applications and even hidden features for advanced users. You will learn not only how to install a new font, but also how to avoid common errors that can lead to system failures.
Official settings MIUI: basic features
To start with, the easiest and safest way is to use the built-in MIUI 12/13/14 tools. The manufacturer offers a limited but functional set of options for working with fonts that do not require superuser rights or install additional software.
- 🔤 Change the font size (from minimum to maximum)
- 🎨 Choose from 5 preset font styles (including Mi Sans and Roboto)
- 📱 Set up display scaling for better readability
- 🔄 Apply bold marking to improve contrast
To access these options, go to Settings → Display → Text Size and Style. Here you will see a sizing slider and a list of available fonts. Please note that after changing the settings, some applications may need to be rebooted to correctly display the new style.
⚠️ Note: When choosing the maximum font size, some interface elements in third-party applications (for example, in Telegram or VKontakte) may not be displayed correctly - the text will be cropped or superimposed on other elements (110-120%).
Among the pre-installed fonts, Mi Sans, Xiaomi’s proprietary solution optimized for high-resolution screens, offers better readability on smaller displays and saves up to 12% battery life compared to standard Roboto thanks to optimized character weights.
Install custom fonts through MIUI Themes
If built-in options are not enough, you can use the official MIUI Themes store, where hundreds of free and paid fonts are available, which does not require root rights and retains a warranty on the device, the main advantage is the ability to preview the font before installation and automatic application to all system applications.
Installation instructions:
- Open the Themes app (icon with brush on desktop)
- Go to the Fonts section through the bottom menu
- Choose your favorite style and click Apply
- Confirm the changes and wait until the process is complete (may take up to 2 minutes)
Among the popular solutions are:
- 🖋️ Product Sans is a pure corporate style from Google
- 📜 Noto Sans is a universal font with support for 150+ language
- 🎨 Dancing Script – handwritten style for creative users
- 🔷 Bebas Neue – ultra-bold header solution
⚠️ Note: Some custom fonts from the theme store may contain advertising modules or collect usage data. Check other users' reviews and theme rating before installing (optimum: 4.5).+ star).
After applying the new font, it is recommended to restart the device to display correctly in all applications. If some software (for example, banking applications) ignores the changes, this is due to their internal security settings - such programs often use the system fonts by default.
Check the MIUI version (update if necessary)

Use of third-party applications: iFont and analogues
For users who need advanced customization options, there are specialized utilities like iFont or FontFix, which allow you to install fonts in.ttf and.otf formats directly from the device without resorting to rooting.
First, most of these programs require you to enable Unknown Sources in your security settings. Second, not all fonts will be displayed correctly in MIUI, depending on the firmware version and device model. Third, some banking and system applications may block custom fonts for security reasons.
Step-by-step instructions for iFont:
1. Download and install iFont from Google Play
2. Download your favorite font in.ttf/.otf format
3. Open the file via iFont and press "Set"
4. Select the option "Copy to iFont"
5. Go to iFont Settings and Apply the Font
6.Reset the device| Annex | Support for MIUI | Root required | Free version |
|---|---|---|---|
| iFont | Partial (up to MIUI 13) | No. | Yes (with limitations) |
| FontFix | Complete (including MIUI 14) | No. | No (7-day trial) |
| ZFont 3 | Partial (problems with Cyrillic) | No. | Yes. |
| HiFont | Complete. | Yes (for some functions) | Free-of-charge |
Important: FontFix-type applications can conflict with MIUI system updates. After installing major updates (for example, switching from MIUI 13 to MIUI 14), custom fonts are often reset to standard fonts and have to be re-installed.
Manual font modification via ADB (for advanced)
For users with technical skills, there is a method of changing fonts through Android Debug Bridge (ADB), which does not require root rights, but involves working with the command line and following instructions accurately, the main advantage is the ability to install absolutely any typeface, including those that are not supported by standard methods.
Before starting work, make sure that:
- 🔌 The phone's debugging on. USB (Settings → The phone. → Version. MIUI → 7 times to tap according to the version → Return to the Extra → For developers)
- 💻 Drivers are installed on the computer ADB and Platform Tools from Google
- 📁 You have a backup of the original fonts (located in the /system/fonts/)
The basic algorithm of actions:
1. Connect your phone to your PC and authorize debugging
2. Copy a new font (e.g., Roboto-Regular.ttf) into the platform-tools folder
3. Follow the commands:
adb push Roboto-Regular.ttf /sdcard/
adb shell
su
mount -o rw,remount /system
cp /sdcard/Roboto-Regular.ttf /system/fonts/
chmod 644 /system/fonts/Roboto-Regular.ttf
reboot⚠️ Attention: Incorrect implementation ADB-If the phone doesn't turn on normally after the reboot, try going to Fastboot Mode. + Volume down and execute fastboot erase cache command.
This method gives you maximum freedom in the choice of fonts, but it requires caution. It is recommended to first test the changes on a backup system or on a device that is not the main one.
What if the font is displayed curved after ADB?
Problems and Solutions: Why the Font Has Not Changed
Even with accurate follow-up, Redmi 10 users sometimes find themselves in a situation where the font refuses to change or is displayed incorrectly.
1.The font has changed only in system applications
This is standard MIUI behavior, with many third-party programs (especially banking and messengers) ignoring the system settings of fonts for security reasons. Solution: try using FontFix-like apps with the Forced Enforcement option, or accept that some programs will use their own fonts.
2.After the MIUI update, the font dropped
System updates often overwrite custom fonts. Solution: Back up /system/fonts/ folder via TWRP or ADB before upgrading, and restore files after updating. Alternatively, use applications with automatic update recovery (e.g. iFont Pro).
3. font is displayed "broken" or with artifacts
This is a sign that the font file is not compatible with your Android version, so try a different font or convert the current font to.ttf with the correct encoding through specialized services, and check that the file is not corrupted (compare its hash with the original).
4. The bold or italic marking does not work
Not all fonts support additional styles. Solution: download the full font package, including files for different fonts (e.g. Roboto-Bold.ttf, Roboto-Italic.ttf, etc.) and install them separately through ADB or font manager.
| Problem. | Probable cause | Decision |
|---|---|---|
| Font not applied | Conflict with the subject of design | Reset the theme to standard in settings |
| Hieroglyphs instead of letters | There is no support for Cyrillic | Choose a font with Unicode support |
| Slow scrolling of text | Too complicated vector font | Choose a simpler font without serifs |
| Post-reset reset | MIUI restrictions | Use applications with autoloading |
💡
If you lose some characters after changing the font (such as emojis or special signs), try installing the Noto Color Emoji font as an optional one, which is specifically designed to display emojis and rare characters.
Optimizing fonts to save battery power
Few people know, but font choices directly affect the power consumption of Redmi 10. This is due to how the processor renders text on the screen. Thin fonts with more detail (such as serifs) require more computing resources to display, which leads to additional charge consumption. Studies show that switching from decorative font to optimized Mi Sans can extend the running time on a single charge by up to 8%.
Recommendations for energy efficient fonts:
- 🔋 Mi Sans is Xiaomi’s standard font optimized for AMOLED-screen
- ⚡ Roboto Thin – minimalist design with low load GPU
- 📉 Open Sans Light – a good balance between readability and economy
- 🚫 Avoid: Times New Roman, Garamond, Brush Script – These fonts add significantly to the load
For maximum savings, combine the correct font with other settings:
- Install a dark theme (saves up to 30% charge on AMOLED)
- Use adaptive brightness with a 60-70% limit
- Enable Read Mode in Display Settings for Monochrome Text Display
Fun fact: on Redmi 10 with Snapdragon 680 processor, the power difference between fonts can be as high as 15% when using instant messengers and browsers, which is because Adreno 610 (the graphics processor in this chipset) is optimized for rendering simple geometric shapes that prevail in sans-seal fonts.
Reset fonts to factory settings
If you've experimented with fonts that have led to unstable system performance or visual artifacts, you can always return the standard settings, and there are several ways to do this, depending on which method of change you used initially.
For changes through Settings/Themes:
- Go to Settings → Display → Text Size and Style
- Choose the standard font Mi Sans or Roboto
- Click Apply and restart the device
For fonts installed through ADB:
1. Connect the phone to the PC
2. Follow the commands:
adb shell
su
mount -o rw,remount /system
rm /system/fonts/YourCustomFont.ttf
rebootFor applications like iFont:
- Open the application through which the font was installed
- Find the option to Restore Standard or Reset
- Confirm the action and wait for the process to be completed
⚠️ Note: If you see problems with the display of text in some applications after resetting fonts (for example, characters instead of letters), this may indicate damage to the system font files. → Additionally. → Recovery and discharge.
For complete cleaning of font cache (recommended for serious glitches):
adb shell pm clear com.android.systemui
adb shell pm clear com.miui.home💡
Before resetting fonts, always back up your current files from the /system/fonts/ folder. This will allow you to quickly restore previous settings if the standard fonts are less convenient than you expected.
