What about settings, though? Don't you have to set up each user profile separate...

I've successfully used Material Files [1] to set a nework shared folder (I think it was FTP) on one Android profile, and accessing it ("connecting" to it) from the other. So this might also work between GrapheneOS profiles.

Sharing files requires a bit of creativity.

You can share with file synchronisation apps like Syncthing/Ouisync [0], exploit a temporary weakness in the isolation model with Inter Profile Sharing [1], or simply copy the files over to an external storage device and transfer them that way.

See: https://github.com/VentralDigital/InterProfileSharing

It also shows that profiles can't really prevent an app from correlating profiles on the same device, by listening on a local socket.
