These two slides have been leaked from a Nokia presentation. IT168 has managed to get some photographs of upcoming and heavily rumored  Lumia pureview phone, but it is not clear whether the phone in the slides is a real phone. The design of the phone rather makes it a fit candidate for a concept Lumia pureview phone.

The specs of the model as shown in the slide are very impressive,

  •  4.3″ curved glass with HD resolution (720p).
  • 41MP camera module as the Nokia 808 PureView.
  • 1080p video recording along with Nokia’s Rich Recording Technology.
  •  The processor is a dual core with Adeno 320 GPU. The only dual core SoC with Adeno 320 is Qualcomm MSM8960 Pro (Snapdragon S4) with 1.5GHz dual core Krait processor.

The capacitive buttons look like WP7 version of OS, but the menu key now bears a Windows 8 logo confirming the Apollo as the OS.
