Hey guys, I just bought a 32 gig Iphone 5 running ios 6. I noticed after the first day when I was on a call the screen light wouldnt go off and sometimes I'd activate speaker phone or mute the call when the phone would touch my cheek. The proximity sensor does not seem to be working at all. I do not have any screen protector or case around the phone thats blocking the sensor and I've reset the phone. Auto brightness isnt working either, it stays where I set it regardless of how dark or bright the room is. Siri wont work with the raise to speak option either. I also downloaded another app ..its a flashlight that turns off when you flip the phone upside down. But the torch light doesnt go off even if the phone is upside down or i cover the sensor with my finger. Anybody else facing this problem? is this likely to be software or hardware?
