New Nokia Lumia 1520 phablet photo leaked ahead of New York launch

Just ahead of the expected next-gen iPhone reveal, Nokia has managed to stand out in the crowd of rumours with a leaked image of the Lumia 1520 smartphone.

The 6in Windows Phone device, once codenamed "Bandit," reportedly comes with a 1080p display and a Qualcomm Snapdragon quad-core processor — and looks pretty much exactly like every other Nokia Lumia smartphone.

Diligent source @evleaks (aka Evan Nelson Blass) tweeted a photo, dubbing the phablet the Nokia Lumia 1520 — presumably due for unveiling at a 26 September press event in New York City.

Based on recent reports, the handset's massive screen means an overhauled Windows Phone 8 OS (GDR3) making way for changes like another column of Live Tiles to take advantage of the extra real estate, as shown in the image above.

The so-called Lumia 1520 will also likely come with a 20-megapixel rear camera, housed under a slight hump at the bottom of the device — similar to the Lumia 925.

Under the same @evleaks handle, Blass last year leaked two photos of the new Windows Phone 8-based Lumia 920 and 820, ahead of their unveiling.

This move comes just days after Microsoft revealed its $7.2 billion (£4.6 billion) acquisition of Nokia's handset business and key mobile IP licenses.

The Redmond-based firm is shelling out $5 billion for the Finnish company's devices and services sector, as well as another $2.18 billion to acquire Nokia's Qualcomm licenses. The deal is expected to close in the first quarter of 2014.
