The Nokia 808 PureView is a Symbian-powered smartphone first unveiled on 27 February 2012 at the Mobile World Congress. It is the first smartphone to feature Nokia's 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 zoom. It was one of the most advanced camera phones at the time of its release in May 2012.

The Nokia 808 features a 41 megapixel 1/1.2 in (10.67 × 8 mm) sensor and a high-resolution f/2.4 Zeiss all-aspherical 1-group lens. The 808's sensor was the largest (over 4 times larger than typical compact cameras) sensor ever to be used in a cameraphone at the time of its launch, a record previously held by Nokia's N8 and, as of September 2014, by the Panasonic Lumix CM1. The 808's sensor remains the highest resolution sensor ever to be used in a cameraphone.

The 808 won the award for "Best New Mobile Handset, Device or Tablet" at Mobile World Congress 2012, and the award for Best Imaging Innovation for 2012 from the Technical Image Press Association. It was also given a Gold Award by Digital Photography Review.

On 24 January 2013, Nokia officially confirmed the 808 Pureview to be the last Symbian smartphone. In July 2013, Nokia released the Lumia 1020, a successor running the Windows Phone operating system common to Nokia's newer products.

PureView Pro is an imaging technology used in the Nokia 808 PureView device. It is the combination of a large 1/1.2 in, very high-resolution 41 MP image sensor with high-performance Carl Zeiss optics. The large sensor enables pixel oversampling, which means the combination of many sensor pixels into one image pixel. PureView imaging technology delivers high image quality, lossless zoom and improved low light performance (see below). It dispenses with the usual scaling/interpolation model of digital zoom commonly used in other smartphones, as well as optical zoom used in most digital cameras, where a series of lens elements moves back and forth to vary the magnification and field of view. In both video and stills, this technique provides greater zoom levels as the output picture size reduces.
