I've been on the phone this morning dealing with touchtone menus where I'd have to "press 1", put the phone back to my face to hear further instructions, "press2", and repeat... Well I found that when I kept putting the phone back up to my face, I WAS PRESSING KEYS!! I CANT GET THE PROXIMITY SENSOR TO SHUT THE SCREEN OFF WHEN ITS AGAINST MY FACE!!! I'm noticing it now because Ive never had to extensively use touchtone menus, and everytime I press an invalid selection, IT HANGS UP AND I HAVE TO CALL BACK! You can't imagine how upset/annoyed I am right now! I tried standing in front of a mirror and adjusting how I held the phone to get the sensor to work, and the only position that worked was about an inch AWAY from my face. If I kept it hovering over my face, the screen would stay off, but the second I pressed it up against my face, the screen would COME BACK ON. So... is anyone else having this problem? Any suggestions? Does it have anything to do with my long hair covering my face/ear? PLEASE HELP!! Thanks guys!
