I had to exchange a dead Palm (9 days old), and am having an odd thing happen on the new one. Every time I want to end a call, I find that my screen has locked. When I unlock it, the phone has opened the contact info. for the person I was talking to. I thought at first I might be hitting the screen accidently during the call and bringing that up, but I tried a couple of calls, careful not to touch the screen at all, and it still happens. The first Pre I had would darken the screen during a call, but would bring back up the dialer when I moved the phone, usually to end the call. Haven't found anything in preferences that would cause this.
