After I ordered the wrong film, I have now resorted to PhoneNatic film. Here is true, in my view absolutely the price / performance ratio. With a little skill, the film can muster good. She has 2 "support films", the first is applied to the actual film, remove any air bubbles and remove the 2nd carrier film. In my view, will create bubbles only if there are on the screen even specks of dust. When the display has been previously cleaned properly can this film super muster. I use a Galaxy S4 and the film fits perfectly. It is equally shaped as the original film from S4, ie recesses Home key, and camera sensors.
A clear recommendation.
The only drawback: Other manufacturers pack a small squeegee to apply it. Only the film and a sparse Cleaning Web is delivered. If you have ever changed sheets, perhaps a doctor has available.
