I had in front of a Samsung Omnia WP7. After WP8 came out I naturally wanted to equal a new model. Quick struck me is that the whole Nokia Windows Phones looked the same or at least similar. I did not want that. Alternatives were quickly found, however, a device that came here as the flagship of Samsung S series and looked but almost paid the price. The Ativ S looks very high quality made but is not quite as high. The cover on the back is made of plastic, for comparing the Omnia WP7 was made entirely of metal. But overall not bad, since the mobile phone is still quite stable and robust. I have the phone now almost 9 months. It gives me a few times fallen down, yet everything is perfect, nothing knarscht or creaks. For OS I want to be brief. I'm a fan of the Windows Phone operating system because finally came out something different and yet sexy. The ATIV S is not only because of its Änlichkeit with the S3 a strong buy recommendation, but because it is very low price, the grandiose displays and good operating system for me.
