Two things left to improve for mobile phone video that would massively increase image quality: increased dynamic range and higher bit rate. Increasing dynamic range in going to be tough. The only way to to do that would be to make the pixel's electron well bigger, but phone cameras have limited pixel size. Image sensors will probably have to provide a separate stacked electron well capacitor below each pixel, instead of using the photosensor PN junction. Also, the industry really needs a standard raw video format that allows for high-quality post exposure correction and white-balance.
