After extensive research (hell again I Phone be ???) we opted for the Lumia 1020. Ok, Microsoft and Nokia have the OS 8.1 no huge community, but what works fine on the machine works well on the phone. And so it is: we are a fan of this as personalized mobile phones, that does not make the operation via nice big tiles for Puzzle. Therefore, equal to: Windows 8.1 for Smartphone is just great. With a few steps you set the part in operation and all major apps are also available from the Windows Store. This one has a full-fledged browser and various NOKIA great apps that do not exist with other manufacturers so. Clear advantage. High praise, we would like especially the app to navigate. The is free plus fast. Really also a highlight. Also class: the camera. Great shots with the lens are guaranteed, a powerful flash is on board and dubbing to a PC is easy. Since the I Phone comes with its comparatively spartan features and especially the mini screen therefore real puny. Speaking of the screen: the Nokia offers a very good display (knackscharf). Disadvantage? Yeah. The maturity is after a few hours "in danger". One should not expect that for example when navigating, browsing and Co. to get along for half a day with a full battery. Good news is that the charger is small and you should also have it here, because that it charges the battery quickly again. And nice it would be if the device "waterproof" as Sony would. But honestly, that's whining at a high level. The NOKIA 1020 is practically highly recommended for Bildermacher and callers.
