Screen protector Crong 7D Nano Flexible Glass for Samsung Galaxy A80 / A90 — hybrid 9H full-screen cover

Crong 7D Nano Flexible Glass for Samsung Galaxy A80 / A90 is a hybrid 9H full-screen cover that combines a flexible nano substrate with a hardened surface layer to protect the phone display. Designed to follow the curved edges of the Galaxy A80 and A90 screens, this protector delivers scratch resistance and impact dispersion while maintaining touch sensitivity and optical clarity. The product fits the entire front surface to minimise exposed areas and helps prevent everyday damage from keys, coins and minor drops.

Advantages

The hybrid construction provides a balance between flexibility and hardness: the nano flexible layer absorbs and spreads impact energy, while the 9H-hardened surface resists scratches from metal objects. The full-screen design covers curved edges for better protection compared with flat protectors. Optical transparency preserves screen colours and contrast, and the thin profile keeps touch response and gesture accuracy. Easy installation and edge adhesion are engineered to reduce lifting and bubbling on the Galaxy A80 and A90 displays.

Suitable for

• Everyday protection of Samsung Galaxy A80 and A90 touchscreens
• Users who want a full-screen cover that follows curved display edges
• Protection against scratches from keys, coins and jewellery
• Reducing damage risk from minor drops and impacts
• Maintaining touch sensitivity for swipes, taps and gestures

How to use

Before application, clean the display thoroughly using the included wet and dry wipes or a microfiber cloth to remove dust, fingerprints and oils. Align the protector with the Galaxy A80/A90 front panel, starting from one edge and slowly lowering it to avoid trapping air. Press gently from the centre outwards to secure adhesion and remove any remaining bubbles. If small bubbles remain, smooth them toward the nearest edge with a soft card or cloth. Allow the adhesive to settle for several hours for optimal edge bonding.

Usage recommendations

For best results, apply the screen protector at room temperature in a dust-free environment. Replace the protector if it shows deep cracks or significant surface damage, as the underlying protective properties may be reduced. Avoid using aggressive solvents on the protector; clean with a soft, slightly damp microfiber cloth to maintain clarity and touch response.
