@futurebird I know this isn´t any help, but my wife and I are in the same predicament with her parents.
We gave them iPhones in the hope that this would make it easier to help them with tech stuff, just walking them through it all. Turns out that both of them really missed out on careers in software QA. I hadn´t realize there were so many ways to do things wrong on an iPhone. 🙄
My father, on the other hand, just flat-out refuses to get a smartphone. It's probably for the better.
