Note: The screen protector is intentionally cut smaller than the display because the edges are curved. There is no impact on display clarity or touchscreen functionality. You will hardly notice any difference compared to a Samsung Galaxy A23 without a screen protector. Scratch-resistant due to the specially hard-coated surface! Highly resistant to scratches and abrasion! 4H pencil hardness. Deliberately smaller than the Samsung Galaxy A23 glass due to its curvature (see photos), bubble-free and can be removed at any time without leaving residue (no adhesive). Easy installation! No bubbling possible on a dust-free display! When applying the film, air is displaced, and it adheres to the display as if by itself. Can be removed at any time without leaving residue! Made in Germany - construction, cutting, and finishing at fair wages in Germany.
