My s2 will not turn on. My phone died so i plugged it in like normal and the phone showed that it was charging. I came back to my phone about 10 minutes later and go to turn it on, it turns on like usual showing the Samsung Galaxy s2 screen then my screen goes black, then it goes back to the samsung galaxy s2 screen. It will do this until i pull the battery. I tried doing a hard reset on the actual phone (holding volume button while turning on the phone) and that didnt do anything. Any ideas why this randomly started happening?
