AT&T Tempered Glass Antimicrobial Screen Protector is strengthened through a specialized tempering process, making it highly impact and scratch resistant. The smooth feel of the glass mimics your device while repelling smudges with an anti-fingerprint coating. It also features PureGuard antimicrobial product protection which reduces 99% of bacterial growth on the surface for the life of the screen. The AT&T Tempered Glass Screen Protector qualifies for a lifetime replacement program, so your screen protector ever scratches, cracks, wears out, or is damaged, we will replace it with another—for as long as you own your device.
