Installing a Switch screen protector prevents scratches—here’s how to do it bubble-free. First, clean the screen with the microfiber cloth included in the protector kit. Use the alcohol wipe to remove grease, then the dust-absorbing sticker to pick up any remaining dust. Peel the protector’s backing film (labeled '1') and align the protector with the screen’s edges and camera cutout (for Switch OLED/Lite). Gently place the protector on the screen—start from the top and let it fall into place, allowing adhesive to spread. Use the included squeegee to push out any bubbles, moving from the center to the edges. If bubbles remain, lift the protector slightly with a plastic tool and reapply, using the dust sticker to remove any trapped dust. Let the protector set for 24 hours before using the console.
