nothing lesser about grapheneos or lineageos at all.

iirc there are problems with trying to use some mainstream apps on these operating systems. When I say lesser I don't mean to demean them, I mean they're the lesser used and not really known about alternative and thus not really supported unless you can live your life in f-droid which if so, kudos to you, you're livin' the dream.

but im all ears if you have a usable alternative for a foss phone.
