Oh I did research supposedly the phone has an armor aluminum top screen layer .-. Which scratches at a level 2 rating on the mohs scale while a fingernail has a 2.5 since it's just a top layer than I think it's fine .... just a minor inconvenience
The thing is I saw it happen while I was trying to see if the other scratches would wipe off the cloth slipped and folded behind itself while I was whiping the screen
