using android ics for one year

now proximity sensor is not working at all . light doesn't turn off while on call .

I removed scratch guard . tried resetting to factory settings ..nothing worked .

downloaded a proximity sensor callibration app and installed it from play store .. i just opened the app and did something

and then tried calling but this time the light never turned on until the call ended ...

again i reset to factory settings.. and it reverted back to old stage ..

now the backlight is always on while on call ...



installed cpu z .. proximity sensor shows 0.0cm always

what should i do ?
