Camera

All of the devices on test have a similar camera set up. The BB Z10, iPhone, Nexus 4 and Galaxy S3 have 8-megapixel snappers on the rear, whereas the Nokia has a slightly larger 8.7-megapixel camera. All devices also have front-facing cameras, primarily for video calling purposes.

As the devices have similar resolution, picture quality is unsurprisingly similar. The camera software also helps to differentiate between them, so we've run through what each has to offer.
