We picked up our iP5s a couple of weeks ago, mine has been perfect (outstanding devices), and I thought the wife's was fine, but I didn't until recently notice her display is +not+ turning off during phone calls (she was on a call and kept turning on the speaker phone, hahaha...) Anyway, I did soft/hard resets, did a full factory restore to 6.0.2 via iTunes (she was initially setup using the backup from her iPhone 4). Even pulled back the top of her screen protector to confirm is wasn't affecting the sensor (though if it was blocking it, I'd kind of assume it would turn it on all the time), at any rate, that didn't fix it either. Figuring it's just a bad sensor, and we just need a phone swap, setup a GBar appointment for Wed, figured they'll just swap it out. We actually purchased these through BestBuy, but figured the replacement would be easier through the Apple Store. They were purchase on Jan 15th, though I think with a defect like this, it's kind of irrelevant since we just wanted it fixed/replaced. OK, all that being said: is there anything else I could try? Figured since we'll have the phone for a couple of more days, if I could resolve this myself, it would save us the trip.
