I bought the Bionic the day that it came out and it has been great. But this evening I was playing "Hanging with Friends" and the screen went blank then went to the black screen with the "Dual Core Technology" logo. Now I can't get it to turn back on... I have taken the battery out and back in several time. I have plugged it up, but the battery wasn't even low when it went off, so that shouldn't matter. The most I can get it to do is just go to the "Dual Core" logo, but the last few times I have tried it has done nothing. Please help! I can't go without my phone!! Any ideas??
