How to change the font on Xiaomi Mi A3: 5 working ways with nuances

Xiaomi Mi A3 is one of the few smartphones of the brand that runs on a β€œpure” Android One instead of the proprietary shell MIUI. This feature simultaneously simplifies and complicates the customization of the interface. If on devices with MIUI, changing the font takes a couple of clicks, Mi A3 owners have to look for workarounds. In this guide, we will analyze all the current ways to change the font, from standard settings to hidden functions for experienced users.

It's important to understand that the Mi A3 has limitations because of Google's policy: Android One blocks deep customization without root rights. But even without them, you can make visible changes. We tested all the methods on Android 10 and Android 11 firmware (the latest official versions for this model) and weeded out outdated tips that no longer work in 2026.

Before you start, check the version of your software in Settings β†’ About Phone β†’ Android version. This depends on the availability of certain features. Also note that changing system fonts can affect the display of text in individual applications – we will note such cases in the relevant sections.

1. Standard font settings in Android One

Despite the limitations, the Mi A3 has basic tools for adjusting text displays, which don’t allow custom fonts to be installed, but help improve readability.

Go to: Settings β†’ Display β†’ Font size and style

Three parameters are available here:

  • πŸ“ The font size is adjustable from "Very Small" to "Very Large" and changes the scale of text in all system and most third-party applications.
  • 🎨 Font style: The choice between Roboto and San Serif (no serifs) may appear as Google Sans on some firmware".
  • πŸ” The scale of the display changes not only the text, but also the size of the icons, the interface elements.

⚠️ Note: When the display scale is larger than 120%, some applications (e.g. banking) may not display correctly or require restarting.

These settings apply instantly, but to fully effect, it may require a device reboot.If you need something more radical than these options, read on.

πŸ“Š What type size do you use on your smartphone?
By default.
Increased (110-120%)
Large (130% and above)
Small (less than 90%)

2. Install custom fonts through the iFont application

For users who don’t have enough standard options, iFont will be the best solution, which allows you to install fonts without root rights using Android features. Importantly, the method works only on firmware before Android 11 – newer versions will require additional manipulation.

Step-by-step:

  1. Download iFont from Google Play.
  2. Open the app and select the Online section to view the available fonts.
  3. Click on your favorite font β†’ Download β†’ Set.
  4. In the window that appears, select Copy to iFont.
  5. Return to the iFont home screen, click Local and select the downloaded font.
  6. Click Set β†’ Confirm installation.

After application, the font will change in system applications (settings, contacts, messages) and some third-party. Google apps (Gmail, Chrome, YouTube) most often ignore custom fonts for security policies.

Download the latest version of iFont from the official store |

Check the Android version (should be no higher than 11)|

Close all background applications before installation-->

⚠️ Note: Some fonts in the iFont collection may contain low-quality Cyrillic characters. Check other users' feedback on a particular font before installing.

If the font has not changed after installation, try:

  • πŸ”„ Reset the device
  • πŸ“² Remove the app cache in Settings β†’ Annexes β†’ iFont β†’ Memory. β†’ Clear the cache
  • πŸ”§ Repeat installation by selecting a different font

3. Using ADB to change font (no root)

For advanced users who are ready to work with the command line, there is a method of changing the font through ADB (Android Debug Bridge), which is more reliable than iFont, and works on all versions of Android, but requires a connection to a computer.

What you need:

  • πŸ–₯️ Computer with Windows/Linux/macOS
  • πŸ”Œ USB-cable (preferably original)
  • πŸ“¦ ADB Tools by Google
  • πŸ“± Included debugging by USB phone-on

Instructions:

  1. Activate Developer Mode on Mi A3 by pressing the Build Number 7 times in Settings β†’ About Phone.
adb devices

(Your device should be displayed)

adb shell

Now download your favorite.ttf font to your computer and transfer it to the /sdcard/phone folder.

su


mount -o rw,remount /system




cp /sdcard/yourfont.ttf /system/fonts/




chmod 644 /system/fonts/yourfont.ttf




mount -o ro,remount /system




reboot

Replace yourfont.ttf with your file name. Once you reboot, the font will change throughout the system.

What if the ADB can’t see the device?
Make sure you have drivers installed for Xiaomi (you can download it on the official website). USB-cable (cheap cables often don't support data transfer) Enable the option "Cancel debugging authorization" in the developer settings USB" And reconnect the device. On Windows, try running the command prompt on behalf of the administrator.

Standard settings❌ No.βœ… Yes.Size/style only
iFont❌ No.⚠️ Partially.Yes (not all apps)
ADB❌ No.βœ… Yes.Yeah (full replacement)
Magisk modulesβœ… Yes.βœ… Yes.Yes (maximum customization)

4. Change font through Magisk (for embroidered devices)

If your Mi A3 has an unlocked bootloader and Magisk installed, you get the most customization options possible, which is suitable for advanced users, since it requires manipulation of system files.

The most reliable way is to use the FontManager module for Magisk, which allows you to install fonts in.ttf or.otf format without manually copying files.

Instructions:

  1. Install the FontManager module through Magisk Manager.
  2. Download your favorite font (recommend verified sources as Google Fonts).
  3. Place the font file in /sdcard/FontManager/.
  4. Reset the device.
  5. After downloading, open Magisk Manager β†’ Modules β†’ FontManager Settings and select the set font.

Important: When using Magisk modules, the ability to use banking applications is turned off (due to the SafetyNet trigger). To get around this, install the Universal SafetyNet Fix module.

Advantages of this method:

  • 🎯 Full font replacement in all applications (including system)
  • πŸ”„ Ability to quickly return to standard font
  • πŸ“ Support for multiple fonts with switching

πŸ’‘

Before installing custom fonts through Magisk, back up the original font. To do this, copy files from /system/fonts/ to a secure location on the memory card.

5. Local font replacement in individual applications

If you only need to change the font in specific applications (such as messenger or browser), you can do without system changes. Many popular applications support customization of text through internal settings.

Examples:

  • πŸ’¬ Telegram: Settings β†’ Appearance β†’ Font size. It also supports custom font themes.
  • 🌐 Firefox: Install Font Changer to change font on web pages.
  • πŸ“– Moon+ Reader: In reading settings, you can select any font from the system or download your own.

For applications without built-in options, you can use Tasker with the AutoInput plugin to force the font change through the CSS-Injection, but it requires a deep knowledge of automation.

Limitations of this method:

  • ❌ It only works in supported applications.
  • ❌ It does not affect the system interface.
  • ❌ May conflict with app updates

6. Restoration of the standard font

If the interface is not displayed correctly after experimenting with fonts (hieroglyphs instead of letters, no characters), you need to return the standard settings. The way you restore it depends on the method you used.

For iFont:

  1. Open iFont and go to the Local section.
  2. Find the set font and click Delete.
  3. Reset the device.

For ADB:

Connect to your device via ADB and do:

adb shell


su




mount -o rw,remount /system




rm /system/fonts/yourfont.ttf




mount -o ro,remount /system




reboot

For Magisk:

  1. Open Magisk Manager.
  2. Find the FontManager module and click Delete.
  3. Reset the device.

⚠️ Note: If after removing the custom font, some applications stopped running, clear their cache in Settings β†’ Annexes β†’ [name] β†’ Memory. β†’ Clear the cache. In extreme cases, you may need to reset the application settings.

πŸ’‘

Always back up your original fonts before experimenting, which will allow you to quickly restore the system to work in the event of a failure.
