I have an issue with proximity sensor on my i9505.
It works well when i reboot my phone... But after 30 min - 1 hour it stops to work.
I'm on c-rom 7.1 but i have this issue on all roms.
I've tried to clean it. I've disassembled my phone and cleaned the sensor with alchool and a cotton fioc, but i have even the problem.
I've noticed the problem because when i go to modify the automatic brightness values, the value "lux" is stopped on a number and doesn't change...
What can be? Please help me!!!
