hello all. I just got the new update a few weeks ago from att and the screen continually will not recognize my face next to it as well as it use to. so of course if the keypad is out you push buttons and possibly hang up on people. I noticed another post without any answers. anyone got any now? Also I have noticed a little more lately that about once or twice a week when I push the power button to wake the phone to unlock I get nothing. I end up having to pull the battery. any help would be appreciated.
