context_page_description: Microsoft Lumia is a discontinued line of mobile devices that was originally designed and marketed by Nokia and later by Microsoft Mobile. Introduced in November 2011, the line was the result of a long-term partnership between Nokia and Microsoft—as such, Lumia smartphones run on Microsoft software, the Windows Phone operating system; and later the newer Windows 10 Mobile. The Lumia name is derived from the partitive plural form of the Finnish word lumi, meaning "snow".
  On 3 September 2013, Microsoft announced its purchase of Nokia's mobile device business, with the deal closing on 25 April 2014. As a result, the Lumia line's maintenance was transferred to 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. In November 2014, Microsoft announced the first Microsoft branded Lumia device, the Lumia 535. In October 2015, Microsoft announced the first Lumia devices running on Windows 10 Mobile, the Lumia 950, Lumia 950 XL and Lumia 550.
context_section_description: In February 2011, Stephen Elop and Microsoft's CEO Steve Ballmer jointly announced a major business partnership between Nokia and Microsoft, which would see Nokia adopt Windows Phone as its primary platform on future smartphones, replacing both Symbian and MeeGo. The deal also included the integration of Bing as the search engine on Nokia devices, and the integration of Nokia Maps into Microsoft's own mapping services. Nokia had planned to use the MeeGo platform as part of its future plans prior to the announcement, although the company announced that it would still release one MeeGo device in 2011. Aligning with Microsoft had been considered a possibility by analysts due to Elop's prior employment with the company.
  Nokia unveiled its first Windows Phone 7-based devices, the mid-range Lumia 710 and high-end Lumia 800, on 26 October 2011 at its Nokia World conference. Motivated by requests from the U.S. carrier AT&T for an LTE-enabled device, Nokia quickly developed the Lumia 900 as a follow-up, first unveiled at the 2012 International CES. The Lumia 900 received heavy promotion by the carrier as a flagship device, but its launch was dampened by a software bug that prevented the device from connecting to certain mobile data networks, forcing AT&T to issue credits to those who purchased the device. Upon its launch in April 2012, the Lumia 900 was listed as a top seller on Amazon.com, but online sales began to taper off by May. While not revealing further details, a Nokia representative stated that the company was "pleased with the consumer reaction, as well as the support we have received from AT&T", while AT&T's mobility chief Ralph de la Vega stated that the Lumia 900 had "exceeded expectations".
  In early 2012, Nokia released the Lumia 610, a new entry-level device taking advantage of the lower system requirements introduced by Windows Phone 7's "Tango" update. These new low-end devices were intended to improve Windows Phone adoption in emerging markets such as China. In June 2012, both Nokia and Microsoft received much criticism after it was revealed that the Windows Phone 7 Lumia devices will not be upgradable to Microsoft's second generation Windows Phone platform, Windows Phone 8. It has been said that those devices won't be upgraded because Windows Phone 8 uses an entirely different kernel (Windows NT). The original Lumia range instead received a different update called Windows Phone 7.8.
  Later in September 2012, Nokia unveiled the Lumia 820 and the Lumia 920, its first two devices to use Windows Phone 8. Both featured NFC, with the Lumia 820 embedding a microSD card slot, and an optional Wireless Charging Shell for Qi wireless charging. The Lumia 920 also notably featured Qi wireless charging, and a "PureView" camera with optical image stabilization. While Nokia received criticism when it was revealed that a demonstration video of its image stabilization technology was, in fact, filmed using a professional camera, the Lumia 920 was a commercial success for the company.
  At MWC 2013, Nokia introduced two more Windows Phone 8 devices: the mid-range Nokia Lumia 720 and the budget Nokia Lumia 520, the latter of which has become the highest selling Windows phone device ever. In 2013, Nokia also introduced the Lumia 925, a revised version of the 920 with a slimmer build incorporating aluminium, and the Lumia 1020, which features a 41-megapixel camera based on technology from its Symbian-based 808 PureView. On 22 October 2013, Nokia extended the Lumia brand into the tablet market with the unveiling of the Lumia 2520; running Microsoft's Windows RT operating system, it was the company's first tablet since the Nokia Internet tablet range. Some critics believed that the usage of Windows RT rather than full Microsoft Windows 8.1 led to bad sales, as most major Windows tablet makers have used Windows 8.1 in favour of Windows RT. Alternatively, others have claimed that the device's failure was due to its heavy weight and high price. Lumia 2520 was discontinued in early 2015.
