Murena Fairphone 5 isn't available in the USA.

Nice thing about Murena is they set up their phone and integrate it with their eCloud/Murena cloud ecosystem. (Their Murena cloud is Nextcloud)

With something like Graphene, you have to set all that up yourself, which I do because I like to host my own Nextcloud.

Also, Murena is a UK company (France) so they're beholden to laws that require them to give 3-letters access to your private data.
