I recently switched the other direction and one rough edge I was surprised to hit on Android is the state of copy and paste for images; on iOS I would copy from Google photos and paste in WhatsApp, now that's just gone and the only option is either Google photos share-to or WhatsApp insert-from. There seems to be pseudo image clipboard support but it's mostly limited to pasting between Chrome tabs afaict.

My switching was due to a build up of minor frictions and frustrations with feeling like a second class citizen on iOS because I use largely gsuite apps rather than being bought into the Apple way for everything, with the last straw being the limitations on Pebble functionality.

I've been a lifelong Android user and still find this a glaring omission. As far as I can tell, copying an image in a browser and then pasting it elsewhere results in a character.
