Support Strange lock screen issues

view story

http://androidforums.com – Hi all, I was wondering whether anyone else has experienced these strange issues with the lock screen. 1. When I press the lock (sleep) button on the side of the phone, the screen turns off, but often when I put the phone down straight afterwards it comes back on by itself. There are no notifications, messages, battery alerts etc either, it just unlocks and sits on the home screen. I'm not talking about the screen which pops up when you wave your hand over the phone either (I'll call this the purple screen) - the phone just unlocks itself and sits on the home screen shortly after I've lock (General)
