I personally don’t like icloud, as I like to just put in 1tb of external memory and only just buy the card and not pay to use that service all the time. I also have a 4gig mobile plan. Not beneficial for me, but could be for OP.

Coming from a s20 maybe she’ll ask where the mini sd expansion port is… hope you got lots of storage.

I have both phones. What I do miss on an iPhone is the complete lack of split screen, multitasking so I can have a tiny window of YouTube open and DEX to use a phone as a computer when connected to a monitor.
