>(in fact, no device at all is reported as having a fully functioning camera, let alone everything else)

Nit: The Pine64 PinePhone's cameras at least have been fully functional since 2021. It's a very shitty pair of cameras, but they're definitely fully functional.

I know the wiki.postmarketos.org page for it says the camera support is "Partial" and that a bunch of drivers are out-of-tree. This and much of the rest of the page is extremely outdated, and I (maintainer) just haven't had the time to go through that page and fix it up.

I'm not a PostmarketOS user (I prefer Mobian), but thanks for maintaining the PmOS Pinephone port. It's thanks to people like you that real Linux distros on phones can continue to work and get better.
