My phone turned off while I was busy, so I turned it on again and after 30 minutes or something it turned off again. It replayed a couple of times. Now my phone won't go on anymore.. I charged it and tried to turn it on but it doesn't. When I charge my phone the light on the top goes on, but nothing really happens.. Can someone please help me. I have this phone like 2/3 months and I've never had a problem before. Please help !!
