The only difference in 920 and 822 is 920 has slightly larger screen and PureView technology camera. The camera is supposed to be better in the dark. The 822 has a Carl Zeiss lens who made lenses for NASA. That lens was developed to compensate for low light pictures. It works on the 822. Great photos in low light. The under the hood and apps are identical on both phones. The 822 is a bargain. It can even be $50.00 at Best Buy on an upgrade. Verizon "phone" customer service cannot match prices. However, if you purchase online at a higher price via Verizon and someone is selling for less they can give you the first month of the phone for free.
