What protects the glass of your Samsung Galaxy Note 9 best? Another layer of glass of course! PanzerGlass makes no concessions and delivers a wafer-thin but extremely strong armor layer for your device. It protects against scratches by keys, coins, paving stones, pub floors, sand, knives, daggers and daisycutters. This privacy case friendly screen protector does not extend all the way to the edges of your screen. This way you prevent your phone case from pushing the screen protector off your screen. This also prevents people next to you from seeing what is happening on your screen. Moreover, the screen feels no different than without protection.
