I'm bringing my new phone in today for the same problem I had with my last one. The camera is much better than my last one but it's doing the same thing when I'm talking to someone. Yesterday I was talking to a buddy and all of the sudden he was on speaker phone and a Facetime call was started. When I hung up I noticed that the keyboard had pressed the 5 button several times too. My question is there a fix for this? Is it hardware or software? I've read both here and the fact that apple gave me a new phone last time I'm thinking it's hardware.
