Finnish mobile giant Nokia Corp introduced its first ever Windows tablet, the Nokia Lumia 2520, and launched a portfolio of large screen Lumia smartphones: the Lumia 1520 and 1320, in Abu Dhabi on Tuesday.

The 10.1-inch Nokia Lumia 2520, running on Windows RT 8.1, combines both 4G LTE and Wi-Fi connectivity, a 6.7MP camera, and for the first time ever on a tablet, ZEISS optics, letting people take good pictures — even in low light.

The Lumia 1520 and Lumia 1320 were the first batch of big screen smartphones introduced by Nokia. With a six-inch screen and the latest software advancements for Windows Phone, the Lumia 1320 and Lumia 1520 are perfectly suited for entertainment and productivity, Nokia said at the event.

On Tuesday's event, Nokia unveiled six new devices in total. Nokia is pulling the wraps off three handsets under $100 for its more basic Asha mobile-phone lineup.

"Now more than ever, mobile devices are at the center of consumers' lives as they look to capture, curate and share experiences on the go,” said Stephen Elop, executive vice-president, Devices and Services at Nokia.

"Today we're inviting people around the world to switch to Nokia. With our latest range of Lumia and Asha products, we're delivering industry leading design and imaging innovation to bigger devices at more accessible prices,” Elop said.

"And clearly, with Lumia and Asha smartphones enjoying quarter-on-quarter volume growth in Q3 2013, that quality and value is resonating with consumers around the world,” he added.

Once the world's No 1 mobile phone vendor, Nokia has lost market shares globally to rivals like Samsung Electronics Co Ltd and Apple Inc.

In China, Nokia was the seventh-biggest mobile phone vendor in the second quarter, but the company was not even among the top 10 smartphone makers in the country during the period, according to a report released by Beijing-based research firm Analysys International.
