After my old S2 I looked around for a new cell phone. The Galaxy Alpha liked optically very good, battery is replaceable. A green-blue tint, as claimed by some, I can not determine. I particularly like that it is easy and is yet to be operated with one hand. The sound is clear. The camera can make pretty good pictures. I would have liked, however, had a place for a memory card. Operating system is Android 4.4, in which I will remain in Zunkunft, although Samsung has promised the immature Android 5.0 with its otherwise disastrous update policy.
