When I read here so as some have difficulties to raise the film, I can only shake his head. It is repeatedly forgotten that the film can be removed again without leaving any residue and just as I can also use several times. If the first attempt fails, so what? What's the problem, then it is withdrawn again and if I want to make sure these are on the adhesive side dust particles it is placed in a water bath and swung there a little back and forth. The surface of the pad or smartphone is slightly damp cleaned and then dried with a microfiber cloth, as this leaves no lint. Then I prepare me a spray bottle with water and a few drops of dishwashing detergent before and spray the foil so that a robust, thus any residues disappear, the dishwashing detergent should I use so that the water surface relaxes and forms a uniform film. Which in turn minimizes the inclusion of air. The water I will run to about 50% of the film, then put them on the surface, best fit the home button, there is still water under the film lets you align well. While holding the scheduled film now and pull with the other hand to the doctor once over the entire surface, so that can not slide the foil. Now the rest of the water with the squeegee from the center underline piece by piece out, and there is a smooth bubble-free surface. The same with the microfiber cloth to carry out (from the center to the edge) and the surface is bright and clean.
