Tecno Spark 40 Plus UV Privacy Tempered Glass Screen Protector, Anti Spy, Fingerprint-ID Compatible, 9H Hardness Scratch Resistant

The Tecno Spark 40 Plus (commonly configured as the Spark 40 Pro+) UV Privacy Tempered Glass Screen Protector is an ultra-premium, high-security shielding system custom-engineered for the device's flagship 6.78-inch 144Hz 3D Curved AMOLED display.

Protecting this specific panel requires a specialized approach due to its steep, rolling side curves and its integrated under-display biometric sensor. Traditional stick-on privacy protectors use conventional adhesives that fail on curved glass and trap micro-air gaps, which completely disrupt optical fingerprint readers. By deploying an advanced UV Liquid LOCA (Liquid Optically Clear Adhesive) system, the liquid gel seamlessly flows across the 3D curves, filling the micro-spaces between the panels to achieve maximum privacy without sacrificing biometric performance.

Core Features & Performance

• Optical Under-Display Fingerprint Compatible: Unlike traditional full-glue privacy glass that blocks or refracts light unevenly, the premium Liquid LOCA gel creates a unified physical conduit between the protector and your screen. Once cured under the UV lamp, it allows the optical under-display fingerprint reader to cleanly scan your thumb print with minimal interference.

• 2-Way Anti-Spy Privacy Filtration: Powered by an integrated matrix of vertical microlouver filters. While looking directly at the screen yields a 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 Spark 40 Plus'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 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 pristine.

• Oleophobic Surface Plating: Finished with a premium vacuum-deposited anti-fingerprint (AF) nano-coating. This layer actively repels natural finger oils, moisture smudges, and sweat. It provides a hyper-slick surface that minimizes tactile friction, perfect for keeping high-speed 144Hz scrolling and fast swiping smooth.

• 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.
