EDIT 11/12/13: Back on the films to stick on the screen. The bonding is done in an easier way than the one provided by Sony (which I had messed up), but against it is very sensitive to scratches. I have hardly used my phone, but the film is already covered by large scratches, and I hope they are not on the phone screen. So the result is very average because these scratches are seen a lot. Film quality provided by Sony was to be better so I advise you not to miss it by pasting.
