As per image phone looks big brother of Lumia 620 and might have 4.7 inch screen and it will be WVGA with no ClearBlack filter on it. It should be noted that if this phone feature 4.7 inch screen then it will be the largest screen phone from Nokia as Lumia 920, Lumia 952, Lumia 928 and Lumia 1020 features max to max 4.5 inch screen.
It might house 2000 mAh battery, it will run on Windows Phone 8 with Amber update out of box. There is no word on CPU but we are hoping for at least 1 GHz processor with 512 MB of RAM.
Till now Nokia has failed to make any impression if we consider high end phone market with its Lumia 920 or Lumia 820, however its low end phone like Lumia 520 has emerged as most popular Windows Phone till now.
