The cut fits perfectly with the provided screen to align everything properly. At transparency, this is what I expected, we see the protection (only because of the dust that settles on the sides of the protective film) and the screen is a little less bright but we made it very quickly, you can compensate by increasing the brightness of a screen of the phone. So no real problems. Regarding the touch, I noticed that the first day of use the protective film is highly adherent, making it difficult slides, this is completely fades eventually and found almost identical touchdown the phone.
Anyway after a few days of use I recommend. Take your time to follow the installation instructions and watch youtube videos. Being in a very clean room with minimal dust helps tremendously.
