Is it just me or do calls (who's calling) take quite awhile sometimes to appear on the screen whether I'm doing something on the phone at the moment or not? Am I the only one that somehow hits the mute button with my cheek accidentally while talking on the phone? I've done it so often that I had to come on here and rant about it because people saying "hello? hello?" and me yelling while driving is becoming too common for me. If you have two people on the line separately how do you hang up on them individually? I've tried to hit menu and figure it out but any "end call" or "red button" attempt just hangs up on both people.
