In the product description it was still to early January 2015, among other things: "for devices with several screens (eg internal and external screen) for each screen a protective film included in the packaging." So I had assumed that a screen protector for the back of the Yotaphone 2 this would be. However, this is not the case! The customer service of atFoliX wrote to me on my request to: "Dear Mr M., please excuse the circumstances Unfortunately Unable to create films for the back, because the display is very convex and the films here after some. would replace time. We will revise the product description in the next few days. " This was all to the Customer of atFoliX :-( The money is still gone. Although the films are very accurate fit for the front and just as usual with frosted films, the brilliance of the display relatively strong worsen (this was me before buying, of course, aware of), but I admit because of wrong product description and then only relatively "strives acting" Customer Service only 3 stars!
