Note: The screen protector is intentionally cut smaller than the display because the edges are curved. There is no impact on display visibility or touchscreen functionality. You will hardly notice a difference compared to a Vivo Y01 without a screen protector. Scratch-resistant due to the specially hardened surface! Highly resistant to scratches and abrasion! 4H pencil hardness. Intentionally smaller than the Vivo Y01 glass due to its curvature, bubble-free, and can be removed without residue at any time (no glue). 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.
