This is the recurrent problems with the tempered Glass Protection Rating IV. As the edges are curved, the film does not stick on and you see a visual change. I do not know how it will evolve over time. This protection is hardly compatible with a Ballistic Tough Jacket Maxx to replace the plastic screen protector Ballistic. Indeed, as the film is not glued to the edges whenever you remove the shell, it must be careful when handing out the cover the edges abut without the protection of silicone on the edge of the film glass. Finally I peeled off.
