Android phones, apps and tablets

Velocio I do think the Nokia Pureview is the exception to the rule. The N8 wasn't bad either, but the Pureview is miles ahead of everything else.

There is no exception to the rule.

If the diameter of the aperture is only 1mm > 3mm, then the photo is goign to be shit quality.

You can use all the software in the world to smooth things out, guess at intermediary pixels, average the readings from multiple sensors to make a good guess... but the fundamental remains true: If you don't give a sensor a lot of light, then you have a shit quality photograph.

All the Nokia Pureview does is accept it has a shit quality photograph and set about guessing how it could try and fool the viewer into thinking it's actually a decent quality photograph.

You can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time. If you want a good quality photograph, grab a camera.
