I suggest you brush the whole package with a wire brush (stable version, development version, you can choose according to your own usage) to see if it works properly:

First use the backup tool of Xiaomi mobile phone to back up, open the system and security ~ backup ~ desktop new backup, and then enter the recovery mode to clear the data.

Backup is to package the data in the mobile phone and back it up to the memory card (Mi2 and Mi3 series are storage devices). Clearing the data three times will only clear the data stored in the mobile phone, not the storage device.
