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 a Samsung Galaxy A52 without a screen protector. The film is scratch-resistant due to its specially coated surface and highly resistant to scratches and abrasion with a pencil hardness of 4H. It is intentionally smaller than the Samsung Galaxy A52 glass because it is curved (see photos), bubble-free, and can be removed without leaving any residue (no adhesive). Installation is incredibly easy! With a dust-free display, no bubbles can form. When applying the film, air is displaced, and it adheres to the display almost automatically. It can be removed at any time without leaving any residue! Made in Germany - construction, cutting, and finishing done at fair wages in Germany.
