How to use

Before installation, clean the device screen thoroughly with a lint-free cloth and any included alcohol wipe to remove dust, oils and fingerprints. Align the tempered glass with the display edges and any cutouts, then gently lower it onto the screen starting from one edge and pressing out air bubbles toward the nearest edge. If small bubbles remain, press them out with a soft card or cloth. For best results, perform the installation in a dust-free environment and ensure hands are clean.

Replace the tempered glass if it becomes chipped, cracked or deeply scratched to maintain protection effectiveness. Avoid dropping the device from extreme heights and clean the protector with a soft, slightly damp microfiber cloth; do not use abrasive cleaners or solvents that could damage the oleophobic coating.
