Is anyone noticing burn in issues on their GS4 screen? I was just about ready to pull the trigger and get one, but decided to make a trip to Best Buy to check it out one more time in person. I picked up the display model with the flip cover with cutout for clock and notifications and was shocked to find severe screen burn in from the clock. I mean really bad. Bad enough to make my eyes bug out trying to focus on anything in that part of the screen. When I asked the sales guy about it he had no response other than to quickly pull it and replace it with a new one. Is anyone else seeing this? I want this phone but not if the screen is going to look like that a few months down the road.
