How to return the standard font to Xiaomi Redmi 9 NFC: 4 working methods

Changed font to Xiaomi Redmi 9 NFC through themes or third-party applications, and now want to return the native system? or after updating MIUI text is displayed incorrectly - too large, blurred or with artifacts? The problem is familiar to many owners of Xiaomi smartphones, especially after experimenting with customization interface.

In this article, we will look at all possible ways to return a standard font, from simple settings in the theme menu to radical measures like resetting to factory settings. We will describe the nuances for Redmi 9 NFC (codename lancelot), taking into account the features of its firmware and the version of MIUI. Also explain why sometimes the font “flyes” on its own and how to avoid this in the future.

Importantly, if you've used root rights or modified firmware (e.g. Xiaomi.eu), some of the methods may not work, and you'll need to flash it back, but most users will have the standard tools of the system.

Why the font on Redmi 9 NFC can change on its own

Before you go back to the factory font, it's worth understanding what caused the problem. On Redmi 9, the NFC is most often to blame:

• 🎨 Installation of custom themes MIUI Themes — many themes change not only wallpaper, but also system fonts. Even after the theme is deleted, the font may remain changed.
• 📱 Update MIUI — sometimes after the update, the display settings are reset, and the system substitutes the default font for the new version (for example, with the new version). MIUI 12 on MIUI 13).
• 🔧 MiuiSystemFont, the system application responsible for rendering text, can fail after cleaning the cache or forced service shutdown.
• 🧩 Third-party launchers (like Nova Launcher or Hyperion) – some of them redefine the fonts for icons and menus.

Less commonly, the problem is caused by corrupting system files, such as after a failed rooting or patch installation via Magisk, in which case the font can only be returned by flashing it.

Method 1: Reset the font through theme settings (the easiest way)

If you changed the font through the standard application Themes (MIUI Themes), then you can return the factory in just two clicks:

1. Open the Themes app (the icon with a brush on your desktop).
2. Go to the I tab (bottom right).
3. Slap the Font item.
4. In the list of available fonts, select by default (usually the first item with the words MiSans or Roboto, depending on the version of MIUI).
5. Confirm the choice with the Apply button.

After that, the system will reset the interface (the screen can blink), and the font will return to the standard. If there is no default, then the font was not changed through MIUI Themes, and you need to try other methods.

Check that you have an official MIUI firmware installed (not custom)

Make sure the Themes app is not removed or disabled

Connect to Wi-Fi – sometimes the system downloads fonts again

Close all open applications (for proper interface reboot)-->

Method 2: Manually remove custom fonts through settings

If MIUI Themes doesn’t have a reset option, but you remember that you installed a third-party font, try removing it manually:

1. Go to Settings → Applications → Application Management.
2. In the search bar, enter Themes and select the MIUI Themes app.
3. Slip on Warehouse → Delete data (this will reset all downloaded themes and fonts).
4. Reboot the phone.

After the reboot, the system must load the standard font, and note that this method will also remove all the uploaded wallpaper, icons and other themes, and you will have to download them again.

If the font is not restored, check the /sdcard/MIUI/theme folder through any file manager (e.g. Mi File Manager). Delete all files with the.mtz extension from there and restart the device.

Method 3: Reset display settings (without data loss)

When the font has changed after the MIUI update or due to a system failure, resetting only the display settings will help – it won’t affect your files, photos or apps.

1. Open Settings → System → Additional → Resetting settings.
2. Select Reset Display Settings (or Reset UI, depending on the version of MIUI).
3. Confirm the action and wait for the reboot.

This method will return to the factory parameters:

• 📱 Type size and style
• 🎨 Color scheme (dark/light theme)
• 🔍 Scale of display
• 📐 Size of icons on the desktop

If the font is changed after reset, the problem may be deeper, for example, in corrupted system files, in which case only a complete reset or firmware reflash will help.

💡

Before resetting your display settings, take screenshots of the current settings in Settings → Screen. This will help you quickly restore the text and icons scale that is convenient for you.

Method 4: Complete reset to factory settings (radical method)

If none of the previous methods worked, there's a hard reset, and it'll bring the phone back out of the box, including the standard font, which will delete all the data from the device, so back up first!

How to perform the reset:

1. Open Settings → About the phone → Reset settings.
2. Select to erase all data (reset to factory).
3. Enter the password (if installed) and confirm the action.
4. Wait for the process to be completed (it will take 5-10 minutes).

Once reset, the phone will reboot and you will have to go through the initial setup, just like after you buy it, and the font is guaranteed to become standard, but all apps, accounts and files will be deleted.

⚠️ Note: Some firmware (e.g. Xiaomi.eu) may block the bootloader if the Bootloader was previously unlocked.

How to avoid font problems in the future

To prevent the font on Redmi 9 NFC from “flying” again, follow these guidelines:

• 🚫 Do not install themes from unverified sources – use only official ones. MIUI Themes or trusted stores like Xiaomi Themes Store.
• 🔄 Update regularly MIUI — In new versions, bugs with font display are corrected.
• 📦 Don't clear the cache. MIUI Themes and MiuiSystemFont manually – this can lead to crashes.
• 🛠️ Avoid rooting if you are not sure about your actions – modifying system files often breaks text rendering.

If you like customization but don’t want to take risks, use a new type change launcher (like Nova Launcher with Nova Google Companion) that only changes the fonts in the shell without affecting system files.

💡

The safest way to customize fonts is to use launchers instead of system tools, which do not affect the stability of MIUI and are easily reset.
