      You might know this already, I’m not sure about Mobian, but postmarketOS at least is usually a mainline Linux kernel, so it shouldn’t matter what android version is installed. Ubuntu touch I think usually uses libhybris and Halium which uses the android kernel and vender driver blobs, which is why it has to have a specific version of android. Those projects have only updated supported to android 9’s kernel so far (i believe). Its also why projects based on Halium and Libhybris usually have better hardware support vs postmarketOS, they’re using the binary blob drivers the manufacturer provided vs reverse engineering them like postmarketOS and mainline kernel approach does.
