You might need features like "macro" to make macro pictures. And "zoom" to zoom. And manual settings to make the best pictures in circumstances like fast moving subjects or dark environments.
All phones can phone. What kind of quality criterion do you have in mind to discriminate between 'good calling' and 'bad calling'?

I would like to know which phone is the best phone. Not which phone has the best features. A phone's main purpose is to send and receive calls. Which phones do that the best???
I am also looking to buy a camera, and want to know which takes the best pictures. Not the camera with the best features, but which one does what it is supposed to do best.
Whenever I am looking to buy electronics, this is the first place I look.
