The tempered glass screen protector creates invisible buttons on your iPhone by adding a touch-sensitive layer on top of the screen. Those buttons transport functions from the upper corners of the screen down to one on each side of the home button—just by tapping the white space. Now any app you use that has those top buttons—like email, Instagram, or notes—is much simpler to use.
Your hand creates the conductivity that powers the touch sensitive technology, so you need to be holding your phone for it to work. On top of the invisible button magic, an Olephobic coating helps prevent fingerprint smudges, and the glass is scratch-resistant. It’s easier to use your iPhone—especially one-handed—with the functions you want easily within thumbs’ reach.
