I was away at camp and hadn't used it the entire week. When I got it back and turned it on, there was a thin black line running down the length of the screen. I shut down my phone and turned it back on, but it still didn't go away. At the time, I was a little busy and the line was on the side, so I didn't get it checked out. It's getting a little annoying now, and I was wondering if anyone knows how I can get rid of it. Am I going to have to get it checked out at a store? Any help would be appreciated. Thanks
