Actually, I want to have 5 only 'some' protector for my Nexus, until my tempered glass arrived from Hong Kong. Out of curiosity, I ordered the cheapest matte film ... and 3 days later I ordered matte screen protectors for all my mobile devices. Super fit. Feel excellent. Who has a little practice in applying films, will get no problems. Otherwise, like all other films also. They protect the screen from scratches, get with the times themselves but scratch - is in the nature of things.
And as he ind Headline: once matt, always matt. For years, I value matt displays with my notebook (non.glare, non-glossy), the exaggerated colorfulness subject with me the readability in difficult lighting conditions. And matt films are the mobile phone much less sensitive to fingerprints than anything else!
