The Nokia Lumia 520 was the fifth Windows Phone 8 handset from the Finnish firm and it slots into the very bottom end of the range, just below the Nokia Lumia 620.
And we do mean just below - the specs of the 520 and 620 are remarkably similar, meaning that Nokias main competition at the bottom end of the market is itself. Theres also the mid-level Lumia 625 that Nokia released last November and the newer Lumia 630 and Lumia 635.
Microsoft has also launched the Nokia Lumia 520s successor, the Nokia Lumia 530. Its another budget smartphone from Microsoft and at first glance it looks like not much has changed, with the Lumia 530 retaining the brightly coloured plastic body, 5MP camera and 4-inch screen.
