Protection very well adapted to the Nexus 4, but the matte coating interferes too image

Positive:
- Size perfectly adapted to the screen and back of the Nexus 4. The screen protector does not interfere at all using a shock-shell (tested with the official Nexus 4 hull)
- The establishment of the protection is well designed and adherence to the screen is perfect, but it does not prevent the taking off later. However it is difficult to perfectly align the risk and put a little crooked.
- The matt protection well limit glare almost without changing the brightness and screen color hues

Negative:
- Unfortunately, the process used to make the screen protector matte screen that appears with a kind of highly visible stationary texture which decreases detail and gives the impression of looking at the screen through a bumpy glass. The sub-pixel screen appear irregularly, and so instead of uniformly see the colors displayed, the more we see the red, green and blue elements of the screen.
- I think it could have been much better if the "grain" of the matte surface was much finer, preventing glare without distorting the pixels / sub-pixels of the image. For example, my PC screen ASUS PA238Q is matte but does not exhibit the problem. Obviously that is especially bothersome on the Nexus 4 because the pixels are very small.

Conclusion: This is especially for the matt appearance that I wanted this protection, since in my opinion this type of protection will not prevent the screen to break if dropped anyway, and the Nexus screen 4 seems scratch resistant. But there, the loss of definition is too large. So in the end I prefer not to put any protection at all.
