Protection of good quality, but the Lumia 920 does not lend itself to host this kind of protection. Indeed, on the one hand the film night at the excellent display quality, and secondly it is very difficult to adjust during installation (on the screen framing domed), for there is no edge on the screen of the Lumia to wedge the film during installation (the film is slightly narrower than the screen). For those who want at all costs protect the screen, the film nevertheless remains a good alternative. I lai removed.
