Note: The screen protector is intentionally cut smaller than the display because the edges are curved. There is no impact on the display quality or touchscreen functionality. You will hardly notice any difference compared to an Oppo A53 5G without a screen protector. Scratch-resistant due to the specially hard-coated surface! Highly resistant to scratches and abrasion with a pencil hardness of 4H. Intentionally smaller than the Oppo A53 5G 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.
