If you have a decent smartphone purchased in last one year, one of the top reason to get a new one would be for better mobile-camera quality. Luckily we have a single online service from GSMArena which allows anyone to not only pitch-n-compare smartphone specifications across a lot of brands, but also compare their picture and video quality side-by-side visually taken at a professional setup providing multiple charts and scenarios (like Good and Low light) to get the best evaluation.
