trgna it was about as smooth as switching from iOS to Android can be. For me even on iphone I always used google’s suite of apps like keep, calendar and Gmail because it just made it much easier to sync across all my devices and if I ever wanted to switch back to Android my stuff could seamlessly transfer so ig my experience was pretty smooth because I already did not use most of apples apps. Nothing os is much cleaner in my opinion than iOS now especially when nothing os 4.0 releases.
