When i catch my phone in the right light i can see scratches/marks, i thought i seen like a dead pixel but it wiped off and thats when i seen them, its hard to decide whether its on the glass or the protector, i use the Spigen Oleophobic protector and don't think i used the phone without a protector so if it is on the glass it must have gone through the protector yet it seems okay. either that or its behind the glass
