I have a series 2 Nike + space gray 42mm and the screen shows small wavy lines in the middle of the screen when you fog it with your mouth! Look at photos! I wipped it and tried to clean it and to see if they are scratches by going over it with my nails to feel but it looks like micro CRACKS/FRACTURES from the underside of the screen. My warranty ends on Dec 26. Anyone has this?
