I'm looking to upgrade my HTC One S to the Z3 compact (holding out hope that T-mobile will carry it). There seems to be a lot of confusion as to what glass is on the Z3 compact. I've had my HTC for 2 years and never used a screen protector. There are microscopic scratches that can only be seen with the screen off and when held at an angle in bright light. With the screen on, the screen looks pristine. Is this what I can expect from the Z3 compact, or is it susceptable to severe scratches?
