I have a smart phone, but struggle to use it. Not for the usual reason in older people - that I cannot cope with the technology but because I am dyspraxic, which means I have no fine motor control and because the tips of all the fingers on my right hand are numb, following a carpal tunnel operation, so I have no idea how lightly or how hard I am tapping,swiping etc etc. If typing text or anything like that I have to do it slowly, to be sure I hit the right tiddly little letters. I struggle with all the icons
I also find the screen far too small, I have difficulty understanding text when I only see it one sentence at a time, completely out of context with the sentence before and after.
Finally I find it very difficult to hear what people are saying if I am rung when I am, say, in the street, a shop, restaurant etc because the ambient noise distracts me. I had a hearing test last week and my hearing is remarkably good, so that is not the problem.
I was talking to a friend yesterday, 20 years my junior who works in a technical job in a tchnologically based industry and she shares many of my problems with a mobile phone.
As I said, I've got one, I use it on occasion, I also use the sat nav on it, it stores my NHS COVID certificate, I use it as a camera. I would love to be able to use it more, but I wish it was the size of a tablet or my Kindle. It would make it so much more useable for me.
