Hi all. Can someone point me in the direction of where to disable the screen lock automatically when plugged in to a charger. I want to use my phone in the car as an mp3 player, but don't want to keep unlocking it every 5 minutes.. I'm sure I came across this option when I first got my phone , but can't find it now. It's driving me mad..... I know I'm a dumb add and its probably really simple... thanks all.
