There are several reasons that PanzerGlass is better than film protection:
Using film protection often causes problems with air bubbles, because film is not a solid material like glass. Therefore, people often struggle with the installation of the film, as it is difficult to get it to sit properly. Most films are also very problematic to reuse, if it have been placed it wrong.
PanzerGlass is more resistant than film, film can usually only protect against scratches. But PanzerGlass protects better against scratches and can even absorb shock damage.
Even the feature that it is made of real glass means that you get a glass feeling when you have PanzerGlass on. In contrast to film where it often can feel rough and “plastic -like”. Most new users feel that they are getting a brand new screen.
