## Long description

The 3MK HardGlass Max Lite Screen Protector for Galaxy S21 5G is a tempered glass shield engineered to preserve the original display clarity and touch response of the Galaxy S21 5G. Designed as an ultra-thin protective layer, it provides enhanced scratch resistance and surface hardness while remaining virtually invisible on the screen. The product fits the device’s front surface precisely and maintains the screen’s color reproduction and brightness.
Advantages
The HardGlass Max Lite combines high surface hardness with slim profile to resist daily scratches from keys, coins and other hard objects without adding bulk. Its oleophobic coating reduces fingerprints and improves wipe-off of smudges. The precise cut and adhesive placement ensure bubble-free installation and stable adhesion across the display. The glass retains full touch sensitivity and supports gestures and multi-touch input.

How to use
Clean the Galaxy S21 5G screen thoroughly with a lint-free wipe and the included alcohol pad, removing dust and oils. Use the provided dust-removal sticker to pick up any remaining particles. Align the HardGlass Max Lite with the device edges and camera openings, then lower it onto the screen starting from one edge to avoid trapping air. Press gently from the center outwards to secure adhesion and remove any minor bubbles by smoothing them toward the edges. Allow a short settling period for the adhesive to reach full bond strength.
Usage recommendations
The protector is intended for impact reduction and scratch prevention but is not a guaranteed replacement for a protective case against severe drops. Replace the protector if it becomes cracked or heavily scratched to maintain optimal display protection and touch performance.
