Even when the Nokia 808 was launched, it had a 41-megapixel camera to make it stand out in the crowd. But, at the end of the day, while more megapixels will give you a ‘larger’ image that image won’t necessarily be as precise.
Rather than focusing on bringing on higher and higher megapixels, smartphone brands should focus on bringing out better lenses and fitting in bigger sensors in order to improve the quality of the images — not just their size.
