The sound of my 5s mobile phone is normal, so the power-on password and SMS key are silent. What happened?

If you turn on the usb debugging mode in the phone settings before locking the screen, you can download the Brush Wizard, which has the function of unlocking the phone. If usb debugging is not started, you can only erase the data by double erasing and restore the factory mode. Press and hold the power button+volume down button in the shutdown state, and then enter the recovery mode. Select Erase Date/Factory Reset to clear data to restore the factory settings, and select Erase Cache Partition to clear cached data. After clicking OK, select Restart System Now to restart the system.
