I've tried holding the power button for 5 and 10 seconds, and a minute, and still nothing. What else can I try?
I was at Tafe today and I was just browsing through G+ with the phone flat on the desk and the screen turned off. I pressed the power button expecting it to switch back on but since then it hasn't turned on. It was on 90% but I've tried charging it and it still won't turn on. It turns on and off (i can tell by the notification LED) and when it's on it still rings when someone calls, but the screen just won't turn. There's no backlight either.
