Despite compliance with all instructions (dust-free display, Aufgringung possible in a dust-free environment, such as in the bathroom), it is almost impossible to satisfactorily attach the film to the screen of the Lumia 630. The reason is in my opinion, partly due to the charging of the film that attracts tiny dust particles, on the other hand the size of the film when attaching the highest precision requires, otherwise strikes the film at one of the corners at the edge of the screen and therefore a small, unsightly but still visible bubble forms. It is true that you peel off the film again and can repeat the process again, the second attempt in principle is always worse (another small dust particles are attracted and trapped when sticking). In this film for the Lumia 630 I have executed introduced only in the sixth film to some extent with no air bubbles and / or dust conclusion, although I am in because of my previous experience in mounting of various films on various smart phones (in the past 5 years about 8 smartphones the family) would call a more experienced user.
The film is suitable for people with a clean room at home and the ability to work with absolute precision. I for one am going to use future smartphones without either film, or buy a film from the merchants around the corner, and suppose that he can attach the film without errors.
