I don't know how it is now, but in the olden days of CM, you could simply talk to the CM guys and ask to be a maintainer for a specific device as long as they thought you wouldn't flake. I can't see why they would change that policy now. The used to say no because you were way too out in the weeds when it came to the changes you made to get stuff working, but if this build is created anyway like it works then that shouldn't be a problem.
All that being said, I found a bug, the max resolution of camera app is showing up as 6MP.
oh that's interesting, I wasn't aware of how that worked.
Google Camera seems to count all 12 but yea Snap doesn't go past 6.
