I make photographs everyday with my iPhone and welcome "hardware," such as an additional lens, which provides more opportunities for making better photographs.
With respect to portrait effects...it sounds like you don't understand who Apple's audience is. And that's causal shooters who make photos of their friends and family and know next to nothing about making portraits nor having the lights, modifiers, etc to do so.

I didn't say it was a bad camera...So im not sure what the point of that photo was... Their HEAVILY advertised portrait mode is absolute garbage. Google handily destyos the iPhone in that regards. The edge detection, or lack thereof is trash. Google has nailed this, Apple has not.
