Well that two films are supplied: The first I could not hang up without foreign bodies / inclusions. Since the included cleaning cloth helps nothing. However, the first film held the particles, which I could not wipe, securely and took them away. The second film I could (almost) hang up perfectly. The two very small inclusions, which are still there but are to recognize only black screen and usually do not interfere. - The screen does not reflect (more). - Fingerprints and smudges form little and can be seen only with a black screen. - If required, the film is easily wiped (little need). - For sure the glass of the display is better protected with foil than without, although it calls itself "Gorilla Glass". The mirror freedom is probably conceded by a rough surface. The roughness is, however, so fine that the diffuse refraction of light rays which display little reduced in sharpness. Due to my strong myopia without glasses I'm still only just be able to recognize the Treppenstufung the pixels on oblique edges and although the film sharpness theoretically reduced (remember - Pixel density: 368 ppi = 15.5 pixels / mm -> Pixel size: 69 microns).
