No impairment of display clarity and touchscreen functionality. You will hardly notice any difference compared to a OnePlus 7T without a screen protector. Scratch-resistant due to the special hard-coated surface! Highly resistant to scratches and abrasion! 4H pencil hardness. Deliberately smaller than the OnePlus 7T glass, as it is curved, bubble-free, and can be removed without residue at any time. Easy installation! No bubble formation possible on a dust-free display! When applying the film, 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.
