1. The screen is perfect, has no pink veil and pulls no streaks as often described. Perhaps there is now and then Grafikfehler (mine is still not noticed), or if very closely looks an edge to the tiles (but only for geeks who want to imagine that). I say to all those who desire to criticize what. Look times on the screens of your android. Tried as times as a gigantic contrast, as in the Windows tiles to produce. You fall but only on any mistakes, because they could never stand out in your tangled unorganized and graphically chaotic Android operating system.
2. The reception is huge, I guess because Stiftung Warentest gemurkst, or Nokia improved. I can only say that the reception is better than the Nokia 1520 where there were problems so no test. In addition, it is better than the Samsung S4 in the same network (even tested).
3. The operating system is fast and top. Tidy, yet customizable. The most important apps are available, less important can be found by looking. There is always a substitute for a corresponding Android app, you just have to see.
Conclusion: If a business - wants to have mobile phone that synchronizes with Outlook, and Word files can open anywhere that you with offline - wherever navigate maps and real megageile sharp camera, as I have in any phone in the world have seen, which is right here.
