as transfer passengers iPhone (iPhone 4) has the Lumia 630 convinced me alone on the speed and reaction time. The Appauswahl is not quite as big as iOS or Android, and some app I already miss and hope that they will be submitted later by the developers, but there are already many apps which I have used on iOS in the Windows Store. If there is not even an app, you can often find after some research an alternative. The tile appearance of Windows 8.1 like it very much, especially the live tiles spice up the smartphone and make it very lively. The matte back cover is reversible and there is it in garish colors. I chose the green and did not regret it. To change I've still worried the orange back cover, there probably also the shiny rear shells are sold for the Lumia 635 also in Matt. The matte backs like me personally but better. The battery life is sufficient to good, we come ever up to 2 days without recharging down when it is not only in their hands and thus playing around. The Lumia 630 is also my first dual SIM phone. The implementation is really very well done, because you can preset for each contact with which SIM you want to call this. In addition, you can also select which SIM to be responsible for data usage.
The camera has no front camera bothers me a little, the back camera is enough for snapshots from the Hellen. A flashlight would the Lumia 630 does not hurt but I can look the other way about it.
When developing with Windows Phones continues and the market share by such favorable beginners smartphones increases, the Appentwickler will recognize the potential in this young operating system and port your apps on this platform. Definitely I will go and stay on Windows Phone and even if it is intended more for beginners to keep the Lumia 630 first.
