How to change the font on Xiaomi Redmi 8T: from standard settings to ADB-team

Why users change fonts to Redmi 8T

Xiaomi Redmi 8T, released in 2019, is still a popular budget device with a MIUI shell. One of the frequent requests of owners is to change the system font. The reasons are different: someone does not like the standard MiSans, someone wants originality, and someone is looking for a font with better readability for low vision.

In this article, we’ll look at all the current ways to change the font, from simple (through theme settings) to complex (manual editing of system files). Importantly, on Redmi 8T with MIUI 12+ and Android 10+, some methods require unlocking the bootloader, which voids the warranty. If you’re a beginner, start with the first two methods — they’re safe and don’t require root rights.

Method 1: Change the font through standard MIUI themes

The simplest and most official method is to use embedded themes. Xiaomi offers several pre-installed fonts that can be activated without any further manipulation, which works on any version of MIUI and does not require superuser rights.

• 🔍 In the lower menu, select the Font section (may be called Font in English firmware).
• 🎨 Scroll through the list of available fonts. Popular options: MiSans (standard), Roboto, SF Pro (similar to the iPhone font).
• 👆 Click on the font you like and confirm the application button Apply.

Limitations of the method:

• ⚠️ The choice is limited to 5-7 fonts (depending on version) MIUI).
• ⚠️ Some fonts may not display correctly in third-party apps (e.g. Telegram or WhatsApp).
• ⚠️ After updating MIUI The font may be reset to standard.

Method 2: Install fonts via MIUI Theme Store

If you don't have enough built-in fonts, you can download additional ones from the official theme store. Many themes include unique fonts that are automatically used when you activate a theme. This method also doesn't require root rights, but it has its own nuances.

Step-by-step:

1. Open the Topics app → go to the Online (or Online) section.
2. In the search bar, enter a query in English: font or typeface.
3. Choose your favorite theme marked Includes font (includes font). Popular options: iOS Font, Samsung One UI Font, Pixel Font.
4. Click Download → Apply. The font will change along with the topic.

Important observations:

• 🔄 To return the standard font, apply the Default theme or Basic.
• 💰 Some topics are paid (cost from 50 to 300 rubles).
• ⚠️ After resetting the settings, the font will reset to the standard.

💡

Before installing the theme, check reviews – some fonts can “move” into the menu or distort symbols in Cyrillic.

Method 3: Manually Replace Fonts with ADB (without root)

For advanced users willing to work with ADB (Android Debug Bridge), there is a way to replace the system font without getting root permissions. This method works on Redmi 8T with MIUI 11-14, but requires a connection to a computer and enable debugging over USB.

2. Connect your phone to your computer and confirm your trust in the device.
3. Open the command prompt (Windows) or terminal (Linux/macOS) in the folder with ADB.
4.

Method 4: Using Magisk and FontManager

If you have a bootloader unlocked and Magisk installed (to obtain root rights), you can use the FontManager module, which gives you maximum freedom in choosing fonts and supports dynamic change without rebooting.

Method 5: Applications for changing the font (with restrictions)

There are apps on Google Play that promise to change the font without root, like iFont or FontFix. However, on Redmi 8T with MIUI, they work partially - the font changes only in some applications (such as Chrome or Gmail), but not systematically.
