The Gadget Guard Black Ice + Cornice edition glass screen guard (Clear) offers superior protection for your Samsung Samsung Galaxy S8. The optical grade tempered glass is incredibly strong, scratch resistant and treated to repel annoying smudges. The Black Ice glass screen protector allows for simple install, just lay the glass screen over the touch screen, tap it in place and it will affix itself to the touch screen. Black Ice+ covers against accidental damage to the screen of a Gadget Guard protected device. Gadget Guard needs to be able to verify that the guard was installed on the phone when the damage occurred, that the device matches the serial # of the device registered, and that there is not extensive or intentional physical damage to the phone.
