How to change the font on Xiaomi Redmi 4X: 5 proven ways (without ROOT and with ROOT)

Xiaomi Redmi 4X is still a popular budget smartphone, but standard MIUI font is not popular for everyone: someone wants to increase the size for ease of reading, someone wants to install a stylish custom font, and someone just gets tired of the monotony. In this article, we will discuss all possible ways to change the font to Redmi 4X, from simple system settings to complex modifications to obtain root rights.

It's important to understand that the ability to change the font depends on the version of MIUI and the bootloader's unlock status. Many methods have stopped working on new firmware (MIUI 12+), but Redmi 4X (released in 2017) is relevant for both old and updated versions. We tested all methods on real devices and we eliminated the non-working ones - here are only verified instructions.

1. Standard MIUI settings: changing the size and style of the font

The safest and easiest way is to use the built-in MIUI options, which do not require super-user rights and are suitable even for beginners. The following options are available on the Redmi 4X:

• 📏 Change of font size: from minimal (small) to maximum (very large).
• 🎨 Style of the font: the choice between the standard MIUI and San Francisco (on some firmware).
• 🔍 Bold text: Enabling thickened display for better readability.

To get into these settings, go to:

Settings → Screen → Text and display size → Font size / Font style

On MIUI 8-9, the path may be slightly different: Settings → Additional → Font size. If you have global firmware, some items may not be translated accurately (e.g., Display size instead of "Display Size").

⚠️ Note: On some versions MIUI 10+ When you change your font style, you may lose indentations in system applications (such as Settings or Phone) that are a firmware bug that is fixed by restarting the device.

2. Installation of custom fonts through MIUI themes

The official way to install custom fonts is to use themes from the MIUI Theme Store, many of which include not only wallpaper and icons, but also unique fonts. Here's how it works:

1. Open the Themes app (icon with brush).
2. Go to the Fonts section (may be called Fonts in English firmware).
3. Select the font you like and click Apply.
4. Confirm the change in the window that appears.

The problem is that on the Redmi 4X with MIUI 11+, the font section is often missing or empty, due to Xiaomi's policy that restricts customization on budget devices.

• 🔄 Retracement MIUI 9-10: These versions have a wider choice of fonts, but new features are lost.
• 🌐 Use of third-party themes: Some developers post font themes on forums (e.g, 4PDA or XDA).

💡

If the Fonts section is missing, try changing the region in your phone settings to India or Indonesia – there are often more themes available.

3. Change font through ADB (no ROOT)

For advanced users who don’t want to root but are willing to work with ADB, there’s a way to replace the system font via a computer.This method works on MIUI 8-12, but requires caution.

You'll need:

• 🖥️ Computer with installed ADB and Fastboot.
• 📱 Included Debugging by USB on a smartphone (Settings) → The phone. → Version. MIUI — Tap 7 times, then return to the additional → For developers).
• 📁 Font in.ttf format (you can download from sites like dafont.com).

Instructions:

1. Connect the phone to the PC and confirm the debugging permission.
2. Open the command line in the ADB folder and execute: Adb devices Make sure the device is defined.
3. Download the archive with a replacement font (for example, MIUI Font Replacer) and follow the instructions from it.

⚠️ Note: Incorrect replacement of system fonts through ADB This can lead to bootloop. Before the procedure, back up the partition. /system Team: Adb backup -f system_backup.ab -system

Download ADB and drivers for Xiaomi| Enable debugging on USB| Make backup system | Check font compatibility with MIUI| Charge phone at least 50%-->

4. Installation of fonts with ROOT-rights

If you're ready to root, you have unlimited options for customizing your fonts. Redmi 4X uses:

1. Unlock the bootloader through the Mi Unlock Tool (the official way from Xiaomi).
2. Install a custom recap (TWRP)
3. Switch Magisk to get root.

You can then use apps like iFont or FontFix that allow you to:

• 📥 Install fonts directly from Google Play.
• 🔄 Change fonts for individual applications.
• 🎯 Set up the interletter interval and line height.

On Redmi 4X with unlocked bootloader, you can install custom firmware (for example, LineageOS), where the choice of fonts is wider than in MIUI. However, this requires experience and can lead to loss of warranty.

5. Alternative methods: Launchers and applications

If all of these methods seem complicated, you can go around the way of using launchers or apps that only change the font in their interface, and it doesn't affect system settings and it's safe.

Popular options:

• 📱 Nova Launcher: allows you to install custom fonts for icons and menus.
• 📝 Microsoft Launcher: Supports font change in settings.
• 🎨 Zooper Widget: To create widgets with unique fonts.

The downside of this is that the font will only change in the launcher, and system applications (Settings, Messages) will remain standard, but you do not need to risk the stability of the system.

Frequent problems and their solutions

When you change fonts to Redmi 4X, users experience common errors, and here are the most common ways to fix them:

• 🔄 Font is lost after the update MIUI: This is because you overwrite the system files, and the solution is to repeat the type change procedure or roll back to the previous firmware version.
• ❌ Not all characters are displayed correctly: The problem is font encoding. Download Cyrillic-enabled fonts (look for Cyrillic or Russian tags).
• 🐢 Phone braked after changing font: Remove cache in Settings → Annexes → Application management → System applications → Settings.

If some characters are missing after the font change (for example, in WeChat or AliExpress), install the Noto Sans CJK font, which supports Asian characters.
