20 megapixels is 5000x4000 which is unpractical, and always scaled down on the web. The phone lens aperture might be too small to capture meaningful details beyond a certain distant from the camera, so 20 megapixels is probably physically overkill anyway. Also, post/processing on the phone lightens underexposed regions and darkens regions that would be overexposed, and then evens white balance to a "nice" contrast. So, understandably, people can find cameras with better optics and "raw" images better for artistic use.
