I have had my phone since Aug. All of a sudden yesterday the bottom of the screen where the phone, apps menu, and contacts list are I got a flickering/blurry screen. It is not constant, just comes and goes. This morning for awhile is was completely blurred out like when your tv used to go out back in the day, and all you would see is colored lines (only these are much finer). Any ideas what is going on? Think an app is causing this, or is it a short of some sort?
