I've had my phone for almost 2 years with no issue. Now the screen is black constantly. I've taken out the battery, put it back in, and charged it overnight with no change. I have read that it may be because of the three senors at the top of the phone, but i didn't think that was the problem. I did take off my clear cover anyway though. No change. I have a different Dare that I've been using so i tried switching the battery. My phone still didn't work and the new one did, so I know it's not a battery issue. I have no idea what's wrong so can someone please help me? Thank you!!
