How to change the font on Xiaomi Redmi 4: from standard themes to custom solutions

Xiaomi Redmi 4 is one of the brand’s most popular budget smartphones, but its standard Miui font is not popular for everyone. Fortunately, the MIUI system offers several ways to personalize text, from simple change of theme to deep customization through root access. In this article, we will analyze all the current methods, their pros and cons, and give recommendations for choosing a font for various tasks, from improving readability to stylish design.

It’s important to understand that the ability to change the font depends on the firmware version and root rights status. Stock MIUI 8/9 (current for Redmi 4) has basic settings, whereas custom firmware like LineageOS or Pixel Experience can have a very different process, and we’ll focus on official and semi-official methods that work without the risk of bricking the device.

If you’ve never changed system fonts before, start with the first section, which focuses on the safest way through built-in themes, and you can immediately jump to the Miui Theme Editor or manual replacement sections via ADB.

1. Change font through standard MIUI themes

The easiest and safest way to do this is to use the built-in MIUI theme change feature, which doesn't require root rights and is suitable even for beginners. In MIUI themes, the font changes in a complex way: along with icons, wallpaper and sounds, but some themes offer unique fonts that are not found in the basic firmware.

To change the font through the themes:

1. Open the Themes app (the icon with a brush on your desktop).
2. Go to the Popular or Fonts tab (if you have one in your MIUI version).
3. Select your favorite theme with the Font in the description (for example, Miui Sans, Roboto, SF Pro).
4. Click Apply and confirm the changes.

Note that not all themes change the font globally, some only affect system applications (Settings, Phone), while third-party programs (such as WhatsApp or Chrome) can display text in their original style.

💡

If the font has not changed after applying the theme, restart the smartphone - sometimes the system applies changes only after the reboot.

• ✅ Pros of the method: safe, fast, does not require technical skills.
• ❌ Cons: Limited font choice, not all themes are free.
• 🔄 Alternative: If there are no Font tabs, try updating the Themes app through Play Market.

2.Use of Miui Theme Editor for custom fonts

For those who want more, but are not ready to get root access, Miui Theme Editor is a good app, which allows you to create your own themes, including replacing fonts, and works on most versions of MIUI, but requires a little more effort.

Instructions for installing custom font:

1. Download and install Miui Theme Editor from Google Play.
2. Download the font file in.ttf format (for example, from DaFont or Google Fonts sites).
3. Open Miui Theme Editor, select Create a new theme → Add font.
4. Import the downloaded.ttf file and save the theme.
5. Apply the created theme through the standard Theme app.

Important: Not all fonts are correctly displayed in MIUI due to system limitations. For example, fonts with Cyrillic characters can "break" when displaying Latin, and vice versa. Before using, check the font for compatibility with applications like FontViewer.
