on s4 locks after 30 mins, power blanks, I hit power button in my pocket and I'm running apps, skipping songs who knows what
on s3 my but, or leg was never able to swipe, on s4 any key and I'm running in my pocket :-(

Change your lockscreen security to pin or pattern entry. This will solve your problem.

changed from password to pin downgrading security to solve problem bad idea, but still no joy.
reset phone
enter pin I'm in, blank screen with power button, home or power un-blank no swipe required, no joy for me but my but, legs, chest likes running applications.
phone still locks up a couple times a day and auto reboots :-(
