Visual Security: The primary function is a built-in privacy filter (usually 2-way, some are 4-way) that obscures the screen from side-angles, typically beyond 28–30 degrees. This prevents "shoulder surfing" in public places like trains, planes, and cafés.
Physical Protection: Most protectors are made from tough aluminosilicate tempered glass with a 9H hardness rating, offering significant resistance to scratches from keys and coins, as well as absorbing impact from accidental drops.
High Clarity (to the user): When viewed straight-on, the screen protector preserves high optical clarity, brightness, and color accuracy, often maintaining 95-98% of the original display quality.
Touch Sensitivity: The ultra-thin design (around 0.29mm–0.4mm) ensures a flawless and fast touch response, reacting like the phone's original screen.
