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.

I've read somewhere that the massive explosion in popularity happened in 2020 when someone stole and cloned the PCs that were used to install the ROMs on Android phones. By then GrapheneOS head dev's conflict with CopperheadOS team was very widely publicized and GrapheneOS's security debate was impossible to miss.

Anyway, here's a phone and a messaging app that will only be provided to you and other criminals, it is very secure
