The Helmet Diamond Glass 4D is a protective screen cover designed specifically for the Vivo Y01. It uses tempered glass with 4D technology to ensure full coverage of the front display, providing a slim profile that doesn't add bulk to your phone. This protector is built to handle daily wear and tear by resisting scratches, impacts, dust, and shocks, which helps keep your screen intact during accidental drops. To maintain a clean look, it features an oleophobic coating that repels grease and fingerprints, while the high transparency ensures your display remains clear and vibrant. You can install it easily thanks to a bubble-free design, and you won't notice any difference in touch sensitivity, as it preserves the precise tactile interaction you expect from your device.
