How to use

Before applying, clean the device display thoroughly with a microfiber cloth and any included alcohol wipe to remove dust, oils and fingerprints. Align the tempered glass with the device front display using the cutouts and edges as guides, then gently place it from one side to the other to reduce trapped air. Press the center of the protector to adhere it to the screen and smooth out any small bubbles toward the edges with a soft cloth or squeegee. If necessary, lift and reapply to correct alignment before final adhesion. Replace the protector when chips, deep scratches or cracks compromise view or touch functionality.

Recommendations

For best results, perform installation in a dust-free environment and handle the protector by its edges to avoid fingerprints on the adhesive surface. Use a soft, lint-free cloth for routine cleaning and avoid abrasive cleaners or solvents that may damage the coating.
