i am facing a problem with my galaxy advance proximity sensor, it does not work while in a call it does not shut my screen off. In the *#0*# menu at sensor tab at proximity it says : PROXIMITY : 1 when nothing is in the sensors way, and not turn the scrren green how it should do. Anyone have a clue about this ?
I find that note3 and S4 have this problem, and can recalibrate with ADB ussing this command:
# echo 0 > /sys/devices/virtual/sensors/proximity_sensor/prox_cal
# echo 1 > /sys/devices/virtual/sensors/proximity_sensor/prox_cal
But in our phone, Prox_cal dont exist! I use italy 4.1.2 official firmware... Any idea?
