With regard to the quality of the film, there were on my old phone no complaints. Extremely resistant, display fully functional, and the finger slipped well above the material. This is also the case with the film for the S3. The application was again easily and without air pockets possible, the recesses for the sensors and the home button match exactly.
I am disappointed, but from the fact that the film does not cover the entire front. At the edges missing each 2.5mm, while the film for the S2 in fact the entire front covered. Besides the fact that this is a visually unattractive broken, that bothers me here is that the uncovered parts are not protected against scratches.
