The BIVA Samsung A57 tempered glass protector is designed to keep your phone's front screen safe from the hazards of daily use. Utilizing 5D technology, the glass features curved edges that provide full coverage across the entire display, while the black frame ensures a seamless fit with the device's aesthetics. This protector is built with high-hardness glass that resists scratches from sharp objects like keys or coins and helps shield the screen from shocks and dust. An oleophobic coating is applied to the surface, which reduces the buildup of grease and fingerprints to keep your view clear. Despite the added layer of protection, the glass maintains the original touch sensitivity, so your interactions with the screen remain fluid and responsive. This pack includes 10 pieces, making it a practical choice for those who want to have replacements ready or for managing multiple devices.
