Hardware:
Feels very valuable. But is also heavier than comparable devices because of the many cameras and the Gorilla Glass on the front and back. [Irony] Finally a phone where the fingerprints are not only forward but also backward to see [/ irony]. Well, a bag will probably be required.
Software:
Was already much too say. A question of philosophy. Either you are on Amazon, is prime customer and perhaps even a Fire tablet, or you have already had an Android smartphone and now weeps bitter tears because of not coming to his apps from the Google Play Goals. You have to weigh halt before. I can only say from my perspective that I miss nothing. For most apps not available there are viable alternatives or corresponding counterparts Amazon.
Conclusion:
Have purchased the equipment for 149 euros. This is a blast from the price / performance ratio. One must not forget the Amazon with this device a few months ago still wanted to attack the iPhone and also the price was accordingly. The current low price can be explained only with massive subsidies. For prime customers: buy recommendation!
