I was nude the first three weeks but even using a leather puch and my shirt pocket most of the time, there are minute surface scratches...so a sceen protector just went on.
I installed a Spigen Ultra Nano Clear
I love the screen nude and don't think this will scratch if I treat it like a baby.
I have an invisashield hd screen protector and you can't tell it's there. The normal invisashield ones have a rubbery texture but the hd ones do not.
