Can I add my font to the Xiaomi lock screen?
No, but with apps like Hi Locker or Lock Screen Widget, you can download custom fonts in.ttf format. You can also replace the system font in /system/fonts/ on root-right devices.
Why does the text disappear after the reboot?
This is a typical problem for methods related to editing lockscreen.db. The system restores the standard settings when you reboot. Solutions: Use an automatic script via Tasker or MacroDroid to re-apply the changes. Go to a third-party blocker that saves the settings regardless of the system.

Best ways: Through the official settings, type in the text of the form “Lost! Call: +7(999)123-45-67”**. Through the Notes widget: specify the contact and offer a reward (for example, “Reward for Return!”**).

Yes, but there are nuances: On POCO with MIUI Global, the option “Text on the Lock Screen” may be called “Owner Info”**. On some models (POCO M4 Pro) you first need to activate “Developer Mode”**. Widgets on the lock screen may not be supported on devices with MIUI 13 for POCO. Check the firmware version in Settings → About the phone.
Can you make the text clickable (for example, so that when you click the number)?
The standard MIUI means no. But with Lock Screen Widget, you can add a quick contact button. Alternative: Contact the OWNER name and your number. In the text on the lock screen, select "Push Emergency Call" → dial ##123##"** (where 123 are the first digits of your number).
