There is about an inch part of my screen that runs horizontal that doesnt respond to touch anymore. I have been using this phone for less than a year, and i havent dropped it. theres small nicks on the plastic housing on the side of the phone from normal wear, but i havent done anything to make the screen do this, it started being weird a week ago and now it doesnt work anymore. does LG cover this? i dont think ill be buying another phone from them if its going to break by itself.
