So I just noticed last night a weird rectangle like scratch on my model S on the upper right portion of the screen. I have not banged anything or even hit the screen but out of nowhere this pops up. When I pass my nail over it to check to see if it’s a scratch, my nail just glides over it like a normal scratch-free screen. I don’t know what happened but I would like to know if anyone else has experienced this. I don’t want to take it service because my warranty is already over. If anyone has any suggestions on what to do or how to help me or if you have experienced something like this, I would appreciate the help.
