My husbands turbo is now not working. He was talking on it and when the call got done he looked down and the phone flickered and went black. He has only had it for like 4 months and I'm pretty pissed. He tried charging it and turning it off and on. You see the screen flicker for a while and then nothing. You can hear it working though and can even feel it vibrate but nothing on the screen. What do I do? We have no insurance on it....
