No impairment of display clarity and touchscreen functionality. You will hardly notice any difference compared to a Huawei Y6s 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 Huawei Y6s glass, as it is curved, bubble-free, and can be removed at any time without leaving residue (no adhesive). Easy installation! No bubble formation possible on a dust-free display! When applying the film, the air is displaced and it adheres to the display almost by itself. Can be removed at any time without leaving residue! Made in Germany - construction, cutting, and finishing at fair wages in Germany.
