Questioning my glass globe has led to the conclusion myself to decide for grade 4. Why: the smartphone away from the lifestyle with all facilities is an important role outside of their own 4 walls take in daily life and for that it needs power, reliability and a certain screen size. This would I start for me at least 5 inches and as the alpha was me at the end to fiddly. This brings me to the point. The new S6e would be perfect, but precisely because of the possibilities is a permanently installed battery clearly nonsense. Initial tests showed 34% battery consumption when S6 in just 2 hours. The new Zeitgeist with fast charging and battery pack awkward, just sick. Thus, I have here at Amazon, the grade 4, which might last of its kind still fast gained AirFrame + with charger, second battery, 64GB SD and Kenu. Compared to the Alpha I tried a magnifying glass to see differences in the screen display. The N4 is of course an absolute high end, top equipment, function and Camera is head and shoulders above the Alpha. Only the camera well draws current and is warm, could the permanent Focus lie? The N4 is set in the media in general to no. 1, that says it all! My recommendation: people bought You still a SP with replaceable battery, more relaxed it may never be again.
