In the area of the window with me within 2 weeks very fast micro-scratches caused on the display!
I have been using no protective film, I thought, the case protects against scratches yes. In the lower part of the imitation leather no micro-scratches are visible. In my opinion, that should not happen in an expensive device with more expensive casing within 2 weeks. It is therefore essential to use a protective film.
Very annoying that my new device already has minute scratches (but fall in normal operation not on) ....
