Microsoft has a new smartphone competitor for the low end: the Lumia 530. Designed as a successor to the popular Lumia 520, Microsoft’s Lumia 530 includes similar specifications and a low price point of just 85 euros ($114) before taxes and subsidies. While the Lumia 525, a revision of the 520, included 1GB of RAM, Microsoft has opted for 512MB of RAM in the Lumia 530 and just 4GB of storage and a quad-core processor. The Lumia 530 also includes on-screen buttons, joining the Lumia 630 as the second Windows Phone to include this new functionality. Microsofts Lumia 530 faces stiff competition from Android
