I noticed this when the background or wallpaper is black or dark. There are several slash lines and marks that are burned onto the screen. They will disappear when the screen is showing lighter colors, but when anything dark comes up (streaming videos, pictures, wallpapers, etc) I can see these lines on the left and right side. There are no marks on the glass, and these lines stay in the same position, even when scrolling. It is easier to see them when in a dark room. I read ebooks and watch shows at night in bed sometimes. It is very noticeable, and starting to get annoying. I will probably be exchanging for another Razr. Anyone else notice this on their phones?
