As for all the adhesive films something frikelig to install. A tip from a review here helped me a lot: In the bathroom shower only turn up the heat and allow it to something actually binds flying lint / dust. Ansonten follow the supplied instructions.
The display brings dust particles etc. best with scotch tape away. Thus, for the way the film removed again when they have completely hook: simply attach scotch tape on a corner and possibly again help out with a little plastic card (press / lift).
