Whoa well for once I feel like a real valid human because everything OP suggested, my android phone settings look exactly as he showed, and he taught me something new ❤️
the camera app may literally be the only thing that every OEM changes! even the most AOSP-adjacent OEMs have bespoke camera apps with their own secret sauce
Yes, they are all slightly different on my phones, yet they look very similar to OPs. For example, on my Samsung and Honor the switch for selfie camera disappears in the Pro mode, while in OPs it's still present. On my Samsung, the shutter speed setting has just an icon and no label, but on the Honor it has no icon, but the label "S"
