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 Amazfit GTS 3 without a screen protector. The film is scratch-resistant due to its specially hardened surface and is very durable against scratches and abrasion with a 4H pencil hardness. It is intentionally smaller than the Amazfit GTS 3 glass because it is curved (see photos), is bubble-free, and can be removed without residue at any time (no adhesive). Installation is a breeze! With a dust-free display, bubble formation is not possible. When applying the film, the air is displaced, and it adheres to the display almost by itself. Removable without residue at any time!
