Quality film, bubble free application but impossible

The films have sure a good quality, the application to a display the size of the Samsung Galaxy Notes, however, seems not to be possible without bladder development.
Clean air bubbles can indeed be actually equal to either wipe or disappear really after at most a few days when applied to the outside, but as soon as even the smallest dust particles is in a bubble, then these bubbles remain permanently exist.
I tried all the tricks to keep dust when applied as far away, but they were even in the best cases, still 3 small dust booze under the film.
If you have the possibility of applying the film in a clean room of an industrial laboratory environment, the bubble-free installation would probably be possible.
After I had tried all the slides, I use my Galaxy Note again without film and have also so no problems with scratches
