Tempered glass with a revolutionary installation method – if you've been apprehensive about this aspect of using tempered glass, your problems have just been solved! The tempered glass from Spigen's AlignMaster series is secured with a mounting frame perfectly tailored to the front of the phone, allowing you to position it perfectly on the screen. The manufacturer has simplified the installation method to the point that it is completely intuitive for any user. The Glass.TR AlignMaster Privacy is a thin coating that has been hardened to 9H during the production and tempering process. This makes it scratch-resistant, even when in contact with sharp objects like keys or a knife. The glass features an oleophobic and hydrophobic layer that prevents fingerprints or other smudges from lingering on the screen. It is crystal clear and perfectly reflects the displayed colors.
