The Helmet Diamond Glass 5D is a protective screen cover designed specifically for the Oppo Reno 7 4G. Crafted from tempered glass, it provides full 5D coverage that extends over the curved edges of the display to ensure the entire front surface is shielded from daily wear. This black-bordered protector is built to resist scratches, shocks, and dust, which helps keep your device in good condition during regular use. Because it maintains high optical clarity, you can continue to enjoy the original colors and brightness of your screen without any visual distortion. The glass is engineered for enhanced tactile sensitivity, so the touch responsiveness remains as fluid as it was on the bare display. Applying the protector is straightforward, as the materials are designed for a bubble-free installation that leaves a clean, seamless finish.
