Previously known as the Nokia Lumia Series, Microsoft Lumia is a range of mobile devices designed and marketed by Microsoft Mobile and previously by Nokia.
Introduced in November 2011, the line was the result of a long-term partnership between Nokia and Microsoft—as such, all Lumia smartphones run the Windows Phone operating system. The Lumia name is derived from the partitive plural form of the word 'lumi', which means 'snow' in the Finnish language.
Microsoft on 3rd September 2013, announced its purchase of Nokia's mobile device business, with the deal closing on 25 April 2014. As a result, the Lumia line is now maintained by Microsoft Mobile. As part of the transition, Microsoft continued to use the Nokia brand on Lumia devices until October 2014, when it began to officially phase out the Nokia name in its promotion and production of smartphones in favor of Microsoft branding.
Also, Microsoft in November 2014, announced the first Microsoft (non-Nokia) branded Lumia device, the Microsoft Lumia 535. The device was first released in India and soon followed by other countries in late 2014 and early 2015. More....
