How to change the font of the clock on the lock screen Xiaomi: all the ways from MIUI 12 to MIUI 15

Xiaomi's lock screen is the first thing you see when you turn on your smartphone, and the font of the watch on it often becomes the subject of picky attention. Some people don't like the standard Roboto, some want to stand out for their unusual design, and some just get tired of the monotony. Unfortunately, MIUI does not offer a built-in option to change the time font on a locked screen - but this does not mean that the task is impossible.

In this article, we will discuss three working methods that will help change the font of the watch without root rights: from hidden MIUI settings to third-party themes and workarounds through system applications. It is important to understand that the capabilities vary depending on the firmware version (from MIUI 12 to MIUI 15) and the smartphone model - for example, on the POCO F5 or Redmi Note 12, the algorithm may be slightly different from the Mi 11 Ultra. We took these nuances into account and prepared universal solutions.

Why Xiaomi does not allow you to change the font of the watch directly?

The lack of direct font change on the lock screen is not an accident, but a conscious decision of the MIUI developers.

• 🔒 Security and uniformity: Xiaomi strives to maintain the integrity of the system interface to avoid application conflicts or visual bugs when using non-standard fonts.
• 🎨 Priority of design themes: The company is betting on changing themes through themes where the font of the watch changes in a complex way together with other elements (icons, wallpaper, animations).
• ⚙️ Technical limitations: The clock font on the lock screen is hard sewn into the system application com.android.systemui, and its replacement requires deep interventions.

However, workarounds do exist — and they don't always require root access or complex manipulation. MIUI 14 there was a possibility of replacing fonts through ADB-teams, and in earlier versions helped third-party launchers or customized themes.

⚠️ Note: Changing system fonts can cause some applications to crash (e.g., banking or high security requirements).Before experimenting, back up your data via Settings → Additionally. → Backup and reset.

Method 1: Change the font through MIUI themes (no root)

The safest and most official way is to use custom themes from MIUI Themes. Many themes change the font of the clock on the lock screen, although this is not always indicated in the description.

1. Open the Themes app (the icon with a brush on your desktop).
2. Go to the Online section and search for “watch font” or “lockscreen font”.
3. Choose your favorite theme (pay attention to the rating and number of downloads), Popular options: Minimal Clock, Digital Bold, Elegant Time.
4. Click Apply and confirm the changes. The font of the watch will update automatically.

If the theme hasn’t changed the font, try the following tricks:

• 🔄 Restart your smartphone – sometimes changes only apply after a reboot.
• 📱 Check compatibility: Some themes only work on specific models (e.g. Redmi). K50 Mi 12 Pro).
• 🔍 Look for topics marked “Full Custom” – they are more likely to affect fonts.

Important: The theme can change not only the font of the watch, but also other interface elements (icons, wallpaper, animations). If you need to save the rest of the design, this method will not work, pay attention to the following methods.

Method 2: Use of the ADB-teams (for MIUI 14 and newer)

With MIUI 14, Xiaomi has added support for changing system fonts through ADB (Android Debug Bridge), a semi-official method that does not require root rights, but requires connecting a smartphone to a computer.

Step 1: Preparation

• 🖥️ Install. ADB Tools on PC (Windows, macOS or Linux).
• 📱 On your smartphone, activate Developer Mode: go to Settings → About the phone and 7 times click on the version MIUI.
• 🔌 Turn on the debugging. USB In Settings → Additionally. → For developers.

Step 2: Connect and commands

1. Connect your smartphone to your PC via USB (select File Transfer mode).
2. Open the command line (or Terminal) and type:

adb devices

(Your device name should appear as a confirmation of your connection.)

adb shell settings put secure sysui_clock_font "name font.ttf"

Where the name font.ttf is a font file pre-loaded to /sdcard/Download/ on a smartphone.

adb shell settings put secure sysui_clock_font "Montserrat-Bold.ttf"

Step 3: Reboot

After completing the command, restart the smartphone:

adb reboot

If the font has not changed, check:

• ✅ Correctness of the font file name (registrar is important!).
• ✅ Support of the font system (not all) TTF-fonts are correctly displayed in MIUI).
• ✅ The firmware version - the method works stably only on the MIUI 14+.

⚠️ Note: Some banking applications (Sberbank, Tinkoff) can block work on devices with active debugging USB. After changing the font, turn off the debugging by USB developer-setting.

Method 3: Third-party launchers with lock support (alternative method)

If the first two methods didn’t work or you need more flexibility, you can use launchers that support lock screen customization.

For example, in Smart Launcher 6 Pro, you can configure the font of the watch as follows:

1. Install the launcher and make it the main one.
2. Go to Launcher Settings → Lock screen → Watch.
3. Select the User Font and upload it. TTF-file.
4. Set the size, color and position of the watch.

The disadvantage of the method: launchers do not always completely replace the standard MIUI lock screen, but only overlap their layer.

• 🔋 Increased battery consumption (5-10%).
• 🚫 Conflicts with system notifications.
• 🔒 Loss of some features (for example, Double Tap to Wake).

💡

Before installing the launcher, check its compatibility with your Xiaomi model on the 4PDA or XDA Developers forums. For example, on the POCO X3 Pro, some launchers may not display time correctly due to firmware features.

How to return the standard clock font?

If the experiments were unsuccessful or you did not like the result, you can return the source font in several ways:

• 🔄 For those. MIUI: Go to Topics. → Mine. → Standard and apply it.
• 🖥️ For ADB-The command is: adb shell settings delete secure sysui_clock_font and reboot the smartphone.
• 📱 For launchers: Remove the third-party launcher or reset its settings to standard.

If the font went off after the MIUI update, try:

1. Clear the System Interface app cache (Settings → Applications → Show Everything → System Interface → Storage → Clear the cache).
2. Reset the lock screen settings (Settings → Lock screen → Reset settings).

⚠️ Note: Some models (e.g. Redmi) 10C or POCO M4 Pro) resetting the lock screen settings can delete fingerprints and pattern lock. check alternative unlocking methods in advance!

Frequent problems and their solutions

When changing the font of the watch, Xiaomi users face typical errors, and consider the most common and ways to eliminate them:

If none of the methods worked, the reason may be:

• 🔒 Manufacturer lock: On some models (e.g. Xiaomi) 13T Pro) font change blocked at firmware level.
• 🛡️ Security Policy: Corporate devices or smartphones with MIUI Russia may have additional restrictions.
• 🐛 Firmware bug: In early versions MIUI 15 (e.g. 15.0.1) had problems with the use of custom fonts.

💡

Before experimenting with fonts, always check the MIUI version in settings (Settings → About Phone → MIUI Version). Some methods work only on specific builds (e.g. global or Chinese firmware).
