## Long description

Hybrid flexible glass Crong 7D Nano for Samsung Galaxy S21 is a full-screen, non-shattering 9H screen protector that combines a flexible nano-material layer with a hard surface coating. Designed to cover edge-to-edge, it reduces the risk of scratches, minor impacts and daily wear while preserving the original touch sensitivity and visual clarity of the display. The hybrid construction balances flexibility and surface hardness to provide durable protection without compromising screen responsiveness.
Advantages
The Crong 7D Nano flexible glass offers a 9H-rated hard coating on a flexible substrate, improving scratch and impact resistance compared with ordinary film protectors while remaining more shatter-resistant than traditional tempered glass. Full-screen coverage helps protect curved edges, and the thin profile maintains touch accuracy and supports smooth gesture operation. The hybrid material reduces the chance of cracking on impact and preserves display transparency and color fidelity.

How to use
Clean the display surface thoroughly with the included alcohol wipe and microfiber cloth, ensuring there are no dust particles or oily residues. Align the protector with the device edges and any cutouts, then gently place it onto the screen starting from one side to avoid trapping air. Apply light pressure to the center and smooth outward to remove bubbles; use a card or the included squeegee if available. If small bubbles remain, they typically dissipate within 24–48 hours as the adhesive settles.
Usage recommendations
For best results, perform installation in a dust-free environment and handle the protector by the edges to avoid fingerprints. Replace the protector if it develops deep scratches, significant edge lifting, or after a strong impact that could compromise its protective properties.
