Anyways, coming to how devices fared in the month of September; Lumia 630 and Lumia 635 kept making gains and combined they are the 2nd most sold Lumia ever after Lumia 520. Lumia 520 also has shown some movement after a hiatus in last months and is now at 30.6%. It is also amusing to see Lumia 521 as the 5th most sold device worldwide.
