I managed to install them without bubbles or inclusions. The trick is to use a squeegee, which goes across the entire width of the display. Once at the bottom (of the narrow edge) centered set the lower backing allowed (denoted by 1) only one or max. two centimeters are separated from the eingentlichen film. The doctor now push rapidly upwards, thereby pulling the carrier film at the same pace in front of it. The me backward by this procedure small air pockets could be pushed without any problems with the squeegee to the edge. This should be done before the upper carrier foil (at 2) is withdrawn. So it prevents the newly applied protective film gets equal scratches.
In conclusion you got so little money for a good screen protector incl. Anti-glare.
Good luck with attaching :-)
