Mounting easy, no long-term solution

The film can be easily angringen (S6 Edge). It is curved at the edges a little and adapts well to the display. Here comes a very few days with light use the foil on the sides a little high, so that accumulate dust and dirt underneath. Is only a matter of time before you "hang" the film remains. Have you removed and disposed of therefore again. Expensive fun for a try.
As a short-term solution to use, for long-term protection should probably be invented even a film.
