Tips for applying: The film must be applied to the display really exactly as it has no "game" to the edges. Will it offset slightly so glued the supernatant side not work properly because the housing survives.
Display first clean with some screen cleaner. Remove the protective film on the back part, and then fix the screen overlay on a corner and the short side of the display. Now the rear protecting foil but do not throw away, but stick back at the opposite corner. So you have a kind of "Henkel" with which you possibly can deduct partially the film again (that goes without handles barely) until you actually flush with the edge of the display. If everything fits, you can remove the handle.
Unfortunately had a little committee until it all came together: you need just a bit of practice ;-)
