Oh, I'm very into this!
What I want to know is whether you can use GrapheneOS as a genuine, no BS replacement for a fully kitted out iphone or android phone.
I want to know what gaps you bumped into.
I want know how much time it takes out of your life to keep the thing working.
I want to know if it's a realistic alternative to Google and Apple.
One last thing, very specific: is there a way to get GrapheneOS to play nice with Apple Calendar? (My whole family is on iphones.)
