Like some others I've seen on this forum, I think a push-the-button-to-unlock AND a move-the-puzzle-piece-to-unlock-again is redundant. I saw where there is an app that will turn off the screen without locking it but isn't anyone else worried that after a few months of use, pushing the power button all the time is going to wear it out? Is there no app to turn on the screen by simply touching it, or touching one of the 4 icons at the bottom of the phone, and THEN moving the puzzle piece??
