Sounds like the phone‘s not the problem. Just don‘t twitter, instagram, facebook, snapchat or whatever you do 24/7 and simply use it for its most useful features. Ditch every social app, delete your accounts. Maybe turn it off every day at a fixed time (quite a while before you‘re in the bathroom brushing your teeth). Leave it at home when you‘re going for a walk. It’s not like there‘s nothing inbetween a flip-phone user and a hopeless smartphone addict.

The point is that choosing to not do these things is hard for a lot of us. Getting rid of a smartphone is a decision you have to make once. Not using Facebook, Instagram, Twitter, Snapchat, Hacker News, and Reddit is a decision that you have to make tens to hundreds of times a day, every day.
