About the Qaulität the films there is nothing to complain about. You could very good application and it was absolutely perfect fit. But what's not at all that through this film quality of the screen is impaired. The razor-sharp AMOLED display is completely lost and you always see a sparkle of foil. In our normal S4 Original was a clear film, which you put next to each other at a direct comparison has. For me, this matte film is a flop.
