I tried switching to graphene after frustration with the latest direction of iOS.

Yes I could use Firefox and ublock to get around YouTube ads, but it actually worked worse than using Orion browser on iOS to do the equivalent. The Pixel 10 Pro couldn’t manage 2x without audio stuttering even at 360p. My iPhone can do it with 4K YouTube video, not that I need that.

iOS natively supports self-hosted contacts and calendars. No hoops. Android needs a separate app that may or may not work (my experience: it doesn’t work and doesn’t give useful feedback when it doesn’t work).

The app quality is so much worse on Android I had to go back. No forward gesture in apps and browsers - insane omission. There are literally only two calendar apps on Android that allow touch-based event editing - Business Calendar 2 Pro (paid subscription) and the Samsung exclusive calendar.

How does a modern smartphone not ship with a decent calendar?? Or touch friendly web navigation?

The rendering engine of the browser is far down the list of priorities compared to supporting basic daily workflows.
