Ok...i need some help. I really hope this hasnt been discussed before b/c i did search. When i'm on a call, my face continuously is pressing buttons or hanging up on whoever im on the phone with. Is there anyway to disable the screen or lock it altogether while on a call? I've tried pressing the lock button, but as soon as I move my face, it comes back on and im pressing buttons with my face. The VZ sales guy slipped one of those privacy screen protectors in my bag without me requesting it (along with a car charger). I should've noticed it, but for some reason, he was able to lower the price of the phone to 149 for me even though i'm not yet eligible for ne2. Really sneaky, I was pissed when i got home. Needless to say, I returned the car charger. Anyway I say that to say that I kept the screen protector and i think it may be interfering with the sensor. Anyone else having similar issues?
