Microsoft has also launched the Nokia Lumia 520’s successor, the Nokia Lumia 530. It’s 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. Nokia Lumia 520 has a fairly generous 4-inch, 480 x 800 display and is powered by a 1GHz dual-core Snapdragon S4 processor and 512MB of RAM.
