How to make bold font on Xiaomi: all the ways for TVs and smartphones

You want to highlight text on your Xiaomi screen — make it clearer and more visible? Fat font helps improve readability, especially on large screens of Mi TVs or on the menu of smartphones with MIUI. But in standard settings this option is often not. In this article, we will discuss 5 working ways to enable bold on different Xiaomi devices — from simple settings to advanced methods using ADB and system modifications.

It is important to understand that not all models support changing the weight of the font out of the box. For example, on Mi TV 4S/5X or Mi Box S TVs you will have to use workarounds, while in MIUI 14+ there are hidden options on smartphones, we will also explain what risks informal methods carry (for example, resetting to factory settings or loss of warranty) and how to minimize them.

1. Standard MIUI settings: where to look for bold?

To start with, the simplest way to check the standard settings is to check the latest versions of MIUI 12-14, and sometimes the option to change the font saturation appears on Xiaomi, Redmi and POCO smartphones.

Open Settings → Screen → Text size and font. Some firmware may have a Thickness slider or a Fat Text switch, and if you don’t have one, your model doesn’t support it (most often on budget devices like the Redmi 9A or POCO M3).

• 📱 Supported models: Xiaomi 13/14 series, Redmi Note 12 Pro+, POCO F5 (on MIUI 14 Global/EEA).
• ❌ Not supported: devices on MIUI 11 and below, and Mi TVs TV (Other methods are needed).
• ⚙️ If you have an option but it doesn’t work, try restarting your device.

⚠️ Note: On some firmware (for example, MIUI China) bold option may not be available even on flagships, in which case it will help to change the region of the system or install global firmware.

2.Bold font on Mi TV: workarounds through display settings

On Xiaomi Mi TVs (including Mi TV 4A/4S/5X/6 and Mi TV Q1/Q2), there is no direct option to include bold font.

1. Settings → Image → Image Mode → Custom: Increase Contrast to 60-70 and Sharp to 50. This visually "weights up" the font.
2. Settings → Special features → Enlarge text: zoom in at 110-120%. Text gets bigger and sharper.
3. Use dark themes (Settings → Personal → Theme) where white text on a black background appears bolder.

For Android TV 10+ models (such as the Mi TV Q1 2023), there is another trick: turn on the Visually Impaired Mode in Special Features, which will make the font bold, but will change other interface elements.

⚠️ Note: On Xiaomi TVs with PatchWall firmware (India), changing the font can cause widgets to malfunction. Before experimenting, back up your settings in Settings → Account. → Mi-account → Backup.

3.Use of ADB-commands for forced inclusion of bold

If standard methods don't work, you can use ADB (Android Debug Bridge), which is suitable for Xiaomi smartphones and TVs, but requires a connection to a computer.

Enable Developer Mode (7 times click on the MIUI version in Settings → About Phone)

Activate USB Debugging in Settings → Additional → For Developers

Install ADB Tools on PC

Connect the device to USB (Use it on the TV. OTG-cable)

-->

After preparation, perform in the command line:

adb shell settings put system font_scale 1.1


adb shell settings put system font_weight 500

The first command zooms in on the font, the second sets the font weight (500 = bold). For Mi TVs, an additional command may be required:

adb shell am broadcast -a android.intent.action.CLOSE_SYSTEM_DIALOGS

The effect is applied after rebooting. If the font becomes too thick, reduce the value. font_weight before 400–450.

4. Third-party launchers and applications for changing the font

If you don't want to mess with ADB, you can install an alternative launcher or a dedicated app, which is suitable for smartphones and Mi Box consoles, but doesn't work on Mi TVs because of manufacturer restrictions.

• 📲 Nova Launcher: allows you to change the style of the font (including bold) in the settings → Font. Supports Xiaomi, Redmi and POCO on MIUI 12+.
• 🔤 iFont (from Google Play): a custom font installation utility that requires root or permission to modify the system.
• 🖥️ TV Launcher (for Mi Box): replaces the standard interface where you can configure text display.

For Mi TVs, third-party launchers are not suitable - the system blocks their installation.

1. Install APK-font file via File Manager (e.g. Google Sans Bold).
2. Use cloud services like Send Files to TV to transfer font files.

⚠️ Note: Installation of third-party fonts on Mi TV It can cause system failure if the font file is corrupted. Before installing it, check for viruses and Android compatibility. TV.

💡

If after installing custom font text became blurry, return the standard font through Settings → Screen → Reset font.

5. Modification of system files (for power users only)

The most radical way is to manually edit system files, which requires root rights or an unlocked bootloader, which voids the warranty, and we don't recommend this method for beginners, but if you're willing to take a chance, here's a quick guide:

On Xiaomi smartphones:

1. Unlock the bootloader through the Mi Unlock Tool.
2. Install custom recovery (TWRP).
3. Download the modified framework-res.apk file in bold (see XDA Developers or 4PDA forums).
4. Replace the original file in /system/framework/ via TWRP.

On Mi TVs:

1. Activate root through an exploit (e.g., MiTV Root Tool).
2. Edit the file /system/etc/fonts.xml by adding the line: <family> <nameset> <name>sans-serif</name> </nameset> <fileset> <file>Roboto-Bold.ttf</file> </fileset> </family>
3. Reset the device.

💡

Modifying system files is an extreme method, and 90% of Xiaomi devices are enough with ADB or third-party applications.

6. Alternative solutions: why can bold not work?

If none of the methods worked, the problem may lie in the following:

• 🔄 Outdated firmware: on MIUI 10 android TV 8/9 Many text display features are limited. Check for updates in Settings → The phone. → Updating the system.
• 🛡️ Manufacturer lock: Xiaomi sometimes disables font change on budget models (e.g. Redmi) 8A or POCO C31).
• 📺 TV restrictions: on Mi TV With an Amlogic processor (models up to 2021), custom fonts are not supported at the hardware level.
• 🔧 Conflict of topics: Some design themes (Mi Theme) override system fonts. Try to bring back the standard theme.

If you are using a Mi TV and none of the ways have worked, consider the following workarounds:

• Connect an external media player (such as Nvidia Shield or Fire TV Stick) where you can configure text display.
• Use voice control (Settings → Smart Assistant → Voice search) instead of reading fine text.
• Install applications that support text zooming (such as Kodi or Plex).

⚠️ Note: Xiaomi TVs with a diagonal of more than 55 inches (Mi) TV Q1 75", Mi TV 665”) the problem of small print is often solved by a simple setup Screen resolution in Settings → Picture → Permission. Try to install it. 4K instead 1080p — text becomes clearer.
