Samsung S21 Ultra UV Privacy Tempered Glass Screen Protector, Anti Spy, Fingerprint-ID Compatible, 9H Hardness Scratch Resistant

The Samsung Galaxy S21 Ultra UV Privacy Tempered Glass Screen Protector is an ultra-premium, high-security shielding system custom-engineered for the device's gorgeous 6.8-inch 120Hz 3D Curved Dynamic AMOLED 2X display.

Protecting this specific flagship panel introduces a major engineering hurdle: the Galaxy S21 Ultra utilizes an advanced, high-security Qualcomm 3D Sonic Sensor Gen 2 (Ultrasonic Fingerprint Reader). Traditional stick-on privacy protectors use edge-only adhesives that trap microscopic air gaps, which completely block ultrasonic sound waves and render biometrics useless. By deploying an advanced UV Liquid LOCA (Liquid Optically Clear Adhesive) system, the specialized liquid gel completely fills those microscopic spaces, forming a unified physical conduit that allows ultrasonic waves to pass through effortlessly while locking down your data from side-glancers.

Core Features & Performance

• Ultrasonic Fingerprint-ID Pass-Through: Engineered specifically to accommodate Samsung's ultrasonic sensor. The cured LOCA gel eliminates the air barrier between the glass sheets, ensuring sound waves can map your thumbprint seamlessly. It provides rapid, reliable biometric authentication that standard full-glue privacy glass cannot achieve.

• 2-Way Anti-Spy Privacy Filtration: Powered by an integrated matrix of vertical microlouver filters. While looking directly at the screen yields a razor-sharp, full-color viewing experience, the view aggressively darkens as the phone is tilted left or right. It becomes completely pitch black past a 30° angle, shielding your banking details, texts, and emails from adjacent onlookers.

• 3D Hot-Bending Curved Coverage: The high-aluminum silicate glass is precision-molded to match the exact profile of the S21 Ultra's sloping screen edges. The liquid adhesive self-levels across the entire surface, creating an incredibly strong, bubble-free bond from edge to edge that standard flat protectors cannot provide.

• 9H Structural Hardness & Scratch Resistance: Thermally tempered for over 4 hours to reach an industrial 9H structural limit. It serves as an elite sacrificial defense layer, absorbing the localized kinetic shock of drops, face-down impacts, and hard friction against keys or pocket debris, keeping your native Corning Gorilla Glass Victus panel pristine.

• S-Pen Optimization & Oleophobic Nano-Plating: Finished with a premium vacuum-deposited anti-fingerprint (AF) nano-coating. This maintains a hyper-slick surface that minimizes tactile friction, ensuring that high-speed 120Hz scrolling, gesture navigation, and S-Pen stylus tracking remain completely smooth without drag or skipping.

• Case-Friendly Perimeter Cut: Precision trimmed by fractions of a millimeter along the outermost rim. This subtle indentation prevents standard protective bumpers and heavy-duty armor cases from pinching the edges of the glass, preventing corner lifting or side peeling
