am thrilled completely. have to say, I switched from a Nokia 6303i classic, so is my first smartphone. but I am super got along, the surface is self-explanatory and I was the choice also use the Desktop PC Windows and not Linux quite clear: Windows Phone. 8.1. is truly a masterpiece and, if combined with the free update to Windows 10 now desktop and mobile, it is perfect. As one and only disadvantage I feel that the smartphone does not include as a network drive to the home network via WiFi (works only on the inserted USB connection) but can no Android or iOS. All around a successful mobile phone with Office, OneDrive and much apps that I do not know what I should first install. And there are no viruses in Windows Phone. The camera is absolutely gigantic, the vivid images are a hit. Each image saves about 1 second in front of the actual picture starting, and watching it does this second then off to the actual picture and then it stands still. Export can be the whole then even as a GIF. When copying onto other media, only the actual JPG is then hergenommen that no longer naturally moves. The whole can also turn off if that should not like. PS it's great. But slowly I come with a bit of practice behind it, it can only be operated with one hand. So this goes. Even if one comes from 6303i classic :)
