It is the first smartphone to feature Nokia PureView Pro technology, a pixel oversampling technique that reduces an image taken at full resolution into a lower resolution picture, thus achieving higher definition and light sensitivity, and enables lossless digital zoom. [3] It was one of the most advanced camera phones at the time of its ...
