No impairment of display quality and touchscreen functionality. You will hardly notice any difference compared to a nubia Red Magic 5G without a screen protector. Scratch-resistant due to the specially hard-coated surface! Very resistant to scratches and abrasion! 4H pencil hardness. Intentionally smaller than the nubia Red Magic 5G glass, as it is curved, bubble-free, and can be removed without residue at any time (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 as if by itself. Can be removed without residue at any time! Made in Germany - construction, cutting, and finishing at fair wages in Germany.
