Update: New film fits perfectly

UPDATE: Shortly after the initial assessment, the team of atFoliX has contacted me. I was offered to get a new slide that fits perfectly now. The length of the film was a little bit shortened, which fits perfectly with the rounded sides of the iPhone.
Kindly I could switch to the clear films, which I can only recommend. Although the matt films entspiegeln the display is very good, but is also agile lost the brilliance of the display.
Together with the small adhesive strip and the real microfibre cloth (not these little pieces produce more lint than eliminate them, and accompanied with cheap sheets) clearly the best film that I know of!

The film makes a very good impression and can be, among other things due to the markings (red grid pattern on the part of the film, which will be deducted later) apply very well.
For me, the film dissolves the iPhone 6 to the upper wheel but quite compares what an unsightly edge results. The question is how long the film therefore keeps on display.
