The film is very well tailored to the mobile phone. I could no differences when operating the touch screen determine what sensitivity or accuracy concerns. From the feeling you realize that you rumdrückt film on a (stable) and not on a glass screen which I do not find bad. The attachment of the film was pretty easy. An illustrated guide and a QR code for demo video were also there. You can also readjust if it was not right the first time properly is if, yes if it were not for the dust. Who has a hermetically sealed-off laboratory, stuck there on the film, all other I recommend not to breathe when sticking and hope :)
