It's a major design flaw - the power button. Too recessed and impossible to hit half the time.
NoLock (Works but I do enjoy having a lock screen.)
Others that I can remember the names of off the bat, but will probably notice them if I see the name.
Most of them work 1/2 the time. They wake using volume sometimes then other times they won't.
Anyone know of one that is viable without rooting?
