I managed to install the film without much trouble (I got picked up twice because I was not in the center) and bubble. Small issue procedural experience (several other movies models left in the trash): identify the positioning of the film on the screen without removing the protections, degrease the screen (glass product) and vigorously wipe with the cleaning cloth provided, begin installation by the bottom of the phone and keep protection (mask 1) under the film by pulling it as and measuring the progress of the installation. This prevents the dust in the air to stick to it, causing the bubbles which can not then discard. The sensitivity of the screen is complete after laying the film. The film is discreet and easy to clean.
