Is my first smartphone and did not think that makes it so much fun, I bought it because of the small dimensions, so I can do it sometimes in your pocket. The battery lasts pretty long after my feel, but have no comparison to other smartphone. Even videos can be watched on the road, have tried several formats, such as AVI and MKV integrate with the wireless router on my Fritzbox 7390, there were no difficulties, recognized immediately. I hope it will remain so long as the state. Ok at the operator must get used to, from a normal cell phone to a smartphone, but it succeeds to a short time. But the most important you can still call with what almost overlooks the many applications which can be draufladen. Is certainly not the fastest, but for the price determined Ok
