Computerized phone photography is not for desktop viewing, printing, etc.
It appears to look "amazing" on phone displays - probably optimized for that.
If my phone photos did bother me, I would turn on RAW mode and do the processing myself.
My "real" camera is a 15 year old Canon Rebel XSi. It's big and can't do a lot of the things my iPhone can and the photos are about the same quality (which is impressive because the Rebel is only 12 megapixels).
