I don't feel qualified to answer that particular question, but I feel about done with smartphones for myself as an adult. I kind of miss my super-basic Motorola flip-phone that I usually left turned off in my backpack.
Or even my pocket of change for a payphone... though that wouldn't work out very well any more.
Lately I occasionally put my phone into airplane mode. It sort of / not really emulates the feeling of old phones and gives a taste of relief from suddenly not being online and at the beck & call of notifications.
