How to make a beautiful font on the phone Xiaomi Redmi 9A: all the ways from system to hidden

Xiaomi Redmi 9A with its modest technical specifications (Helio G25 processor, 2 GB of RAM) nevertheless allows you to flexibly customize the appearance of the system - including fonts. But if the brand's flagships are limited to typography only by the imagination of the user, on budget models like Redmi 9A, many functions are hidden or require workarounds. This article is not about the standard resizing of text in Settings → Display, but about real ways to make the font unique: from official MIUI themes to manually embedding custom files.ttf.

We tested all methods on Redmi 9A with MIUI 12.5 and MIUI 13 (Android 10/11) firmware. Importantly, some tricks will require unlocking the bootloader or root rights — but we separately highlighted safe options for beginners. Also, the article looks at common errors (for example, why the font is reset after a reboot) and gives recommendations for optimizing performance, since not all fonts work equally well on weak hardware.

1.Official way: MIUI themes with custom fonts

The easiest and safest method is to use the built-in MIUI theme gallery. While Redmi 9A doesn't support changing fonts directly (unlike the Redmi Note 10 Pro or POCO F3), many themes include unique headsets. Here's how it works:

• 📱 Open the Themes app (icon with brush on desktop).
• 🔍 In the search bar, enter the query: font or font (in English layout).
• 🎨 Scroll through the results – look for topics marked “Includes font” in the description.
• 💾 Click Apply, after which the system will automatically install a new headset for all system applications.

Advantages of the method: it does not require root rights, reversible (you can return the standard font through the reset of themes), and fonts are optimized for MIUI. However, the choice is limited - mainly Cyrillic and Latin headsets in the style of sans-serif (for example, MiSans, Roboto Slab).

⚠️ Attention: After update MIUI through OTA Custom fonts from the themes may be reset. To avoid this, save your favorite theme in My themes before the update. → Save.

2. Hidden function: changing the font through ADB (no root)

Few people know, but in MIUI There is an undocumented ability to change system fonts through ADB (Android Debug Bridge. This method works with Redmi. 9A without unlocking the bootloader, but requires a computer and USB-Important: the method is only suitable for.ttf fonts compatible with Android.

Step-by-step:

1. Download Google’s Platform Tools and unpack the archive.
2. Turn on the phone Debugging over USB (Settings → About Phone → MIUI Version → 7 times click on the line, then go back to Additional → For Developers).
3. Connect Redmi 9A to your PC and in the command line (in the folder with the platform-tools) do:

adb devices


adb shell

If the device is determined, continue:

su -c "cp /sdcard/Download/your_font.ttf /system/fonts/"


su -c "chmod 644 /system/fonts/your_font.ttf"

Replace. your_font.ttf to your font file name (you need to pre-download it and put it in the Download folder on your phone) and after rebooting, the new font will appear in the display settings.

Download Platform Tools on PC|Enable debugging on USB phone-on|Download the font in.ttf format|Place the font in the Download folder|Check the connection via adb devices-->

⚠️ Note: Not all fonts are correctly displayed in MIUI. Avoid files larger than 5MB – they can cause lags on Redmi 9A Because of limited RAM, test fonts for compatibility before installation.

3. Font Change Apps: What Works on Redmi 9A

There are hundreds of apps on Google Play that promise to change the font "with a single click," but 90 percent of them either don't work on MIUI or require root rights, and we tested the top-end solutions and identified the ones that actually work on Redmi 9A:

For Redmi 9A without root, iFont is optimal.

1. Install the app from Google Play.
2. Select a font from the directory (e.g. Montserrat or Open Sans).
3. Click Set → Apply via MIUI Theme (if the option is not available, use Apply via ADB as in the previous section).

Critical detail: apps like iFont create an overlay over the system font, which can conflict with some games (like PUBG Mobile or Genshin Impact) – they will make the text unreadable. Before installing the font, close all games and restart the phone.

💡

If you have "squares" instead of letters in your apps after you change the font, then the headset you choose does not support Cyrillic. Try fonts marked "Cyrillic" in the description, for example, PT Sans or DejaVu Sans.

4. Manual font embedding via TWRP (for advanced)

This method is suitable for users who have unlocked the bootloader and installed custom recovery TWRP. It allows you to replace the system fonts with any, including exclusive headsets (for example, SF Pro from Apple or Google Sans).

Instructions:

1. Download the archive with fonts in.zip format (for example, from the XDA Developers forum).
2. Reboot Redmi 9A to TWRP (clip Power + Volume Up).
3. Select Install → specify the path to the archive with fonts.
4. Sweep through the archive and run Wipe Dalvik/Cache.

Recommended font sources:

• 🔗 XDA Developers (Segment of Xiaomi Themes & Apps).
• 🔗 DaFont (filter under 100% Free license).
• 🔗 Google Fonts (all fonts are free for personal use).

⚠️ Please note: Do not replace the Roboto-Regular.ttf file in the /system/fonts/ — This can break the text display in system notifications. Instead, add new fonts to the folder and edit the file. system_fonts.xml into /system/etc/.

5. Optimizing fonts for performance

Redmi 9A is not very powerful, and some fonts can significantly slow down the system, for example, decorative headsets with multiple serifs (for example, Lobster or Pacifico) increase the load on the processor when rendering text.

• 📉 Use sans-serif fonts: Roboto, Open Sans, Noto Sans.
• 🗜️ Compress font files via Transfonter (select the option) WOFF2 for better optimization).
• 🔄 Limit the use of custom fonts only for system applications, and for games and instant messengers leave the standard ones.

You can check the impact of the font on performance through Settings → Battery → CPU use: If after the headset change the process system_server began to consume more 15% CPU — Go back to the standard font.

💡

On Redmi 9A, the optimal font size for balance of readability and performance is 14–16px. Larger fonts (18px+) can cause slowdowns when scrolling long lists (for example, in Telegram or Chrome).

6. Problem Solving: font is reset or displayed incorrectly

Redmi 9A users often face three common problems after changing the font:

1. The font is reset after the reboot, because MIUI restores the standard settings when you update the cache. Solution: use the FontFix app with the Lock Font option (requires root).
2. Some apps don't change the font -- many programs (like WhatsApp or Instagram) ignore the system fonts. Solution: Use overlay utilities like iFont with Force Apply.
3. Text is displayed "curve" or with artifacts - this is a sign of font incompatibility with the screen resolution of Redmi 9A (720×1600). Solution: choose fonts that support HD+ (for example, Noto Sans Display).

If the problem doesn’t resolve, return the standard font through the theme reset (Settings → Themes → Reset to Standard) or rollback changes to TWRP.
