Nokia Lumia 930 is the best windows phone that can exist thanks in part to the outer layer "Cyan". Very advanced photo application, a fast enough grip, and a very nice screen. I do not regret abandoning android polué unnecessary applications with access to all your smartphone and stuffing you all your RAM. lumia 930 with no need to reboot often to empty the RAM. I ordered this smartphone in good condition refurbished, yet it was new. I do not regret my purchase.
