LG Rebel 4...I just purchased it and even though I've gone into tools/settings/display and changed it to 30 (or even "stay on forever") minutes it still goes blank after a few seconds. Also, how do I power my phone down? There are only 2 buttons and the only thing they do is turn my notifications volume up and down.
