An unannounced Nokia smartphone has appeared in a Windows Phone promo video and many believe the device, with its large screen, to be the leaked but unannounced Nokia Lumia 900, which should best the Lumia 800 on specs. Currently, Nokia has only announced the entry-level Nokia Lumia 710 and the more feature-rich Nokia Lumia 800, both of which run the Windows Phone Mango operating system.
The Lumia 900 is also believed to sport the codename of Ace. Speculated specs include 4G HSPA+, 4G LTE, a larger 4-inch or greater display, and either 16 GB or 32 GB of on-board storage.
Curiously, the device in the video appears to lack the three Windows Phone navigation keys for back, Windows or home, and search. The front of device is dominated by a huge touchscreen.
The video of the phone has since been made private, but a screenshot is posted here for reference.
