I've always found it odd nobody, specifically Samsung or Sony (since Sony already makes their own high-end CMOS sensors), doesn't ship a phone with a slightly superior sensor? Yes, I get the unit economics of it (at least I think I do, I've never worked in the phone industry so that could easily be hubris on my part), but if you can spend an extra few dollars or even tens of dollars on your BOM for something that is…
Certain iPhones were manufactured by Samsung, cameras for a long time were almost exclusively supplied by Sony.
I guess someone ran the number on that and figured it would make more sense financially.
