Yes, but took a detour via CalyxOS 3 or 4 years ago. Not for long though, Graphene is better in my opinion.

CalyxOS isn't a hardened OS and reduces rather than improving security. It doesn't provide comparable fundamental privacy improvements such as Storage Scopes, Contact Scopes, Sensors toggle, per-connection MAC randomization and many others either.
