CNbeta.com reports that a slightly upgraded Nokia Lumia 820, the Nokia Lumia 825, has popped up in China.

The handset has been upgraded from 8 to 16 GB of storage, and now features the same Puremotion screen with supersensitive touch as the Nokia Lumia 920, vs the earlier AMOLED screen.

The specs remain otherwise the same, meaning a dual-core 1.5 Ghz processor, 4.3 inch screen, and 8 megapixel Carl Zeiss camera with dual-flash, and will run the latest version of Windows Phone 8.8.

WinP.cn speculated the device variant may be a customized version for a carrier, much like in the US at present with the Nokia Lumia 810. The upgraded device is expected to hit the market in February 2013.
