As most I wanna protect the iphone screen so I put on one of those clear screen protectors, but when i'm on a call and have the phone next to my face it goes blank like it's supposed to, but when I'm ready to hang up and take the phone away, it doesn't wake back up because it senses the film and thinks it's still by my face. So I end up waiting 5 seconds or so and hit the wake/silent button and it goes back to the locked home screen....anyone else with this problem cause it's kinda annoying.
