I switched in october 23 on grapheneOS from my iPhone. I absolutly agree that android is not even close to ios. I was a bit of a shock for me xD But, where shadows are there is also light. The installation from opensource apps was really refreshing for me. After 4 months I understand a bit more why privacy is a path to walk through and not a apprupt change. With my independence through grapheneOS, I no longer plan to switch back to iOS.
I've gotten used to Calyx. Some things need improving though. Maps and notifications mostly.
Apple make a great product, but they're still exploiting and controlling all your info. For me no more apple. Waiting for the graphine on apple for my old devices
