/e/OS is that middle ground between GrapheneOS and stock Android, and it has most of the benefits of the former while stripping away most of the deficiencies of the latter. You also don’t have to use Murena’s cloud suite, but it’s pretty good for what it is if you do want or need that part of it.

And a bonus is that /e/OS runs on every device that can run GrapheneOS in addition to other devices, and the Fairphone 6+ is one of them.
