Nokia mobile hardware and software updating books
In 2010, its market share had declined to 28%, and in April 2012, Samsung Electronics (a prominent user of Android) ultimately overtook Nokia as the largest mobile phone vendor in the world.
Nokia's CEO Stephen Elop vetoed the idea of producing Android devices, believing the company wouldn't be able to suitably differentiate its Android products from that of other vendors.
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.
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.
From 1998 to 2012, Nokia was the largest vendor of mobile phones in the world, which included early smartphones built on its Symbian platform.
However, in recent years, its market share declined as a result of the growing use of touchscreen smartphones from other vendors, such as Apple's i Phone line and Android-based products.
It was one of two known Android projects at the company; the other was running the OS on low–end Asha hardware, which resulted in the Nokia X family of devices.
In an employee memo, Elop infamously described the company as being on a "burning platform", blaming the "war of ecosystems" between i OS and Android as part of Nokia's overall struggle, and asserting that the company needed to make major changes to its operation.
