Personally, I have a proper camera, but I am not carrying it around with me at all times. My phone takes excellent pictures (I have a pixel 6) but I do feel the lack of zoom.
The quality of the main cameras hasn't really gone up in a few generations; but I do think there's been significant improvements in the photography department in phones in the last 5 years. Wide lens, macro photography, zoom lenses. These are genuine innovations.
It does make me a bit angry when software is kept locked into new models when older models are perfectly capable of running it though. But there's been hardware innovation for sure. Don't really see much of a reason to go from a Pixel 7 pro to a Pixel 8 pro, and probably not going to be the case for a few years. But who knows.
