How to use

Clean the iPhone 17 display thoroughly with a microfiber cloth and any provided alcohol wipe, removing dust and fingerprints before application. Align the tempered glass with the device screen using the camera and sensor cutouts (if applicable) and, starting from one edge, gently lay the protector down while pressing the centre to allow adhesive to spread evenly. If air bubbles appear, use a soft card or the supplied tool to push them toward the edges. Ensure the edges are securely seated and allow a short settling period before reattaching a case or placing the device in a pocket.

Apply the protector in a dust-free environment to reduce the chance of trapped particles. For best privacy performance, avoid extreme screen brightness settings that can increase sideways visibility. Replace the tempered glass if it sustains deep chips or cracks that compromise touch performance or privacy effect.
