The Alpha and Omega is the first-time application of the film on the display. Here the phone display should be absolutely clean and free of dust and ideally also the space in which you work. I have therefore applied the film in a very damp room (after showering) in one go. These best fix the film not just piece by piece on the display, but the best remove the carrier foil completely, then the outside include the protective film at the edges and even hang up and then deliberately rausdrücken resulting air bubbles. The Screengards films can be in this sense, simple and well-attach, because the fit is very good and also the recesses are cut cleanly.
However, one must say that the films are relatively thin, at least compared to my previous, which has not so far been a negative impact for me. Here the long-term testing is still pending.
As already mentioned by a previous speaker, the film is quite sensitive to fingerprints and grease streaks. This is not necessarily beautiful, but would not have been different without foil.
I can only recommend the film!
