I have already had this film on my old Samsung S2 Plus. They met very well its purpose. The picture quality is only minimally affected. This bothers me, however little, because the matte film the everyday comfort increases considerably. No annoying mirrors longer in the sun. I highly recommend this film.
Contraindications:
The film is extremely measured on the phone display. You have to muster a lot of patience, so that the film is properly seated. I burned the first film and then I went and did the foil at the edge of each cut 1mm. Thus, the film is read properly apply without bubbles.
