This is how Sony have designed the software, they are using the same tech as Nokia do in their Lumia devices called 'Pixel Binning' in order to make better overall image quality.

There is currently no ability to change the resolution over 8mpx on the superior auto mode.

yes but can sony add the ability to change it to 20.7 mb in the next firmware ?
