I have a Samsung focus with an "always on" proximity sensor. So the phone does not light up after it has moved away from ones face during a phone call, making it impossible to use after any call without a restart.
I have tried the following solutions.
1- Soft Reset by pulling the battery and waiting
2- Hard reset using numeric codes provided in the ref threads
3- Using the diagnostic menu.
With regards to the third one. The proximity sensor menu shows that the sensor is always "on" no matter where the phone is. But there is no "set" or "reg' button that I can find with which to recalibrate it, the only option is "exit"
It is quite possible that I am missing a feature or function or I need a new solution. If anyone has any insight that would be really helpful.
Thank you in advance.
