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.

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.

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.
