The Helmet Diamond Glass 5D is a tempered glass screen protector designed specifically for the Samsung Galaxy A16 4G. It utilizes 5D technology to provide full-screen coverage, extending across the curved edges to ensure the entire front display is shielded from daily wear. With a 9H hardness rating, the glass is built to resist scratches, shocks, and dust, which helps keep your device looking new even with frequent use. To maintain a clean viewing experience, the protector features an oleophobic coating that minimizes fingerprints and smudges while providing HD clarity. Its thin profile ensures that the phone's original appearance and weight remain unchanged, and the black borders blend seamlessly with the screen. You will notice that the touch sensitivity remains fully responsive, allowing you to navigate your phone naturally while benefiting from a durable layer of protection.
