Note: The screen protector is intentionally cut smaller than the display because the edges are curved. There is no impact on the display's visibility or the touchscreen functionality. You will hardly notice any difference compared to an Amazfit GTR 3 Pro without a screen protector. The film is scratch-resistant due to its specially hardened surface and highly resistant to scratches and abrasion with a 4H pencil hardness. It is intentionally smaller than the Amazfit GTR 3 Pro glass because it is curved (see photos), bubble-free, and can be removed at any time without leaving residue (no adhesive). Installation is very easy, and bubble formation is not possible on a dust-free display. When applying the film, the air is displaced, and it adheres to the display almost automatically. It can be removed at any time without leaving residue. Made in Germany - construction, cutting, and finishing at fair wages in Germany.
