- Install a file manager with root support (such as Root Explorer).

|---|---|---|---|
| Standard settings of MIUI | ⭐ | No. | Short text, no customization |
| Lock Screen Info | ⭐⭐ | Authorizations for notification | Could be in conflict with MIUI |

4. Alternative methods: widgets and wallpaper with text

- 📱 Widgets: Some launchers (like Nova Launcher) allow you to add text widgets to the lock screen.
