I went to make a phone call today and when I hit the slider down all the sudden my screen went to a bunch of colorful vertical lines then black. I can hit the power button and sometimes it will pop of the screen perfectly clear, no issues, and sometimes nothing, and sometime lines, and sometimes really really dark screen. I didn't drop it. In fact this is a replacement phone from verizon that I have had for maybe 2 months. When I got it, after like 2 days the lights at the bottom that are your buttons went out, and then will work with certain applications, but not most. Im guessing it is a short somewhere or circuit issue. either way I'm guessing time again for a new phone. Let me know if anyone has had this issue and resolved it. Thanks.
