haha, none at all! I've spent like 6 months trying to boot normal NixOS instead of mobile-nixos, got it booting last week, almost nothing works, currently I'm trying to build a newer kernel and maybe fix sound.

I quite like the boot chain that I achieved (bootloader -> tianocore EDK II UEFI from Renegade Project -> normal systemd-boot) and I also installed the whole thing via USB by mounting disks directly.

On Mobian I think at least one camera did work but was purple all over, never actually tested the hardware on android.

All mobile distributions ship without kernel modules that I need, compiling manually on every update is not really sustainable, this is the reason why my setup is so convoluted.
