No impairment of display representation and touchscreen functionality. You will hardly notice any difference compared to a Samsung Galaxy A41 without a screen protector. Scratch-resistant due to the specially hard-coated surface! Highly resistant to scratches and abrasion! 4H pencil hardness. Intentionally smaller than the Samsung Galaxy A41 glass, as it is curved, bubble-free, and can be removed without residue at any time (no adhesive). Extremely easy to install! 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. Removable without residue at any time! Made in Germany - construction, cutting, and finishing at fair wages in Germany.
