One of the images [above] is probably of the Lumia 920, Nokia’s new flagship smartphone that will boast of a 4.5-inch display and PureView camera. The Lumia 920 is said to have a dual-core processor, NFC, 4G LTE connectivity and expandable storage.
The second image [below] is purportedly of Lumia 820 that will be equipped with a Carl Zeiss camera lens and will feature a 4.3-inch display. Not much is known about this phone as yet except the above two things.
Nokia is holding a press event with Microsoft on September 5.
