Putting on this screen protector is very simple. The latest iPhone models, such as the 12, 13, 14, and 15, have edge-to-edge screens without a Home button, making an alignment tool crucial for proper installation. Spigen’s screen protector installation stands out as the best we’ve come across, and the provided visual instructions make the process straightforward. Each package contains two plastic installation trays, with the glass already in position. After cleaning your phone’s screen with the provided alcohol wipe, dry wipe, and dust-removal sticker (if needed), you remove the backing from the screen protector and attach the frame to your phone. This design prevents any misalignment of the glass. The instructions direct you to press and slide along a sticker on the front of the protector and then remove the frame.
