I am wondering, what are the "many forks" of GrapheneOS?
I know Nitrokey phones but afaik they just preinstall GrapheneOS
Then there was this one scammer company from somewhere in Europe that used GrapheneOS on cheapo phones, havent heard from them anymore.
Then there is "un plug gedphone" which uses "Li bertOS" no idea what that is based on, they steal Hypatia from DivestOS and are shady as heck, their hardware is likely also very cheap.
Then there is BharOS, a closed source indian GrapheneOS fork for use in Governments, that sounds like the only real fork out there.
And the FBI might have forked GrapheneOS but no idea how reliable that is.
I know no other forks or potential forks.
