[Q] Proximity Switch off
My screen was not getting on after making the call so I wanted to check the service menu. I typed *#*#7378423#*#* and accessed the calibration menu and selected Proximity sensor menu.
It showed Autoscreen Brightness On and Proximity Switch OFF. I switched Autoscreen Brightness off (other wise the calibrate option is grayed out) and tried to calibrate the proximity sensor. I got the error -99 and the message that it cannot be done.
1. How do I switch on the Proximity sensor on
2. Will the calibrate option work if the phone is factory reset (there is a message which says - Pls factory reset the phone before calibrating).
Thanks in advance.
