I feel like the Pinephone Pro is super close to being what I want, so I think Framework could totally take it the rest of the way. They could ship with AOSP, but also support Linux mobile as well.

I’m a developer and I’m totally willing to help with the rest of the little things, but it needs to fulfill my basic requirements first. If parts are easy to replace (e.g. upgrade the camera by sliding in a new one w/ USB-C), I’d pay a premium for it even if the actual functionality kinda sucks.
