do you think its a hw problem, or is it something what may be fixed via an update?
Hi, I had the same problem with you before.
then I fixed it, by doing this following steps :
1. Removing the screen protector(was not the default one you sometimes get with the phone), just check you donít lose your warranty
and then, this is the stupid ( but magic
2. Switch off the phone
3. Press firmly on the entire top of the phone for about 3-4seconds (top part of the screen, left side from your speaker)
4. Switch back on
5. Once started up, press again on the top part of the screen.
6. Finally you can try to dial *#*#7378423#*#*
for check your Proximity Sensor is ON or OFF.
