Why Choose Anti Spy Screen Protector: With this film on, your screen will only be visible to people directly in front of the screen, keeping your personal, private and confidential information hidden from strangers. Please note that the privacy cover will slightly darken the screen to prevent the eyes from peeping close to you, so increase the brightness of your device screen for a better viewing experience. PRECISE CUT: Advanced precision laser cutting technology ensures that the film covers your device as much as possible. High Sensitivity: High sensitivity and HD definition give you fast app start, smooth play of games and videos, allowing you to enjoy the convenience of fluidity. Self-Healing Technology: The self-healing technology allows the film to recover from minor scratches within 48 hours and keeps the screen looking new.
