Darkening Of Screen
Hi All, I am new to this forum but i beleive that there are lot of experts here. I hv recently Jb'ed and unlocked a 3G i phone, it is working perfectly fine, but barring one issue. The screen becomes dark after some time when a call is going on (both incoming and outgoing), even tapping on the screen does not help. The only way to bring it back is to lock keypad via on/off switch and then unlock keypad again.
Any clues as to why this could be happening.
