The firmware may be bad, yet I take a picture faster on my Sony compact camera than I do with my smartphone thanks to the physical buttons. I can also do it while cycling while doing the same with my smartphone is annoying as fuck in winter with gloves, in summer with sweat and expose the risk of losing and destroying my precious pocket computer.
Also for some my phone screen show as a black screen when using my polarized sunglasses while the lcd of my camera is still visible and allow me to point and shoot quickly. No idea what is the difference in tech on both that would explain that difference.
Most flagship smartphones may be super responsive but the average sub 200usd smartphone won't necessarily fire up the camera app faster than my Sony compact camera. And there is no way I will buy a 600 to 1000usd smartphone. I'd rather repair/replace either a 200usd smartphone or a second hand compact camera in the event I drop it and break it than a single 1000usd one.
Also from my experience with friends using flagships and apple ones, even the best smartphones are crappy under low light. Smartphones are great during the day, once it is dark they are pretty much useless.
