I just know noticed that my screen has a line across it. It about a third of the way down from the top and doesn't run all the way across. It kind of has a "dead pixel" appearance but not as distinct. Its not as noticeable on a light colored screen. It's extremely visible on the sign on screen. I guess I'll being calling Samsung tomorrow. I have several Samsung devices plus several others and have been blessed to have never had an issue. Anyone else?
Step away from the edge! A little alcohol and a swipe of a microfiber cloth and it was gone. Sorry, I wished that could have deleted this post. It was strange and believe to be something like a clear adhesive left over from production.
