I have a cheap smart phone. I hardly ever use any of the features, except text and phone. One really useful thing, though, is being able to take and send a photo quickly and easily. Last week I needed to send some photos of my problem to a tradesman, and it was just so easy.
Really, the best compromise for me, would be two phones, a simple one, that just makes calls, then a smart for all the cleaver stuff. I'm still trying to fathom out my new Iphone 13's features, trouble is, some are so complex, I quickly forget how to work them and have to experiment again..
It's predecessor, a little SE, constantly offered app updates - this 13, once it had got them up-to-date, hasn't flagged up any at all, apart from a couple of OS updates.
