I also did this, although only for a while. I first removed all notifications and apps from my phone (although I do not use social media anyway), and eventually went to some cheap flip phone. However, once I had to go rescue my wife when she locked her keys in the car.. And it took me 2.5 hours when it should have taken 1 hour because I got lost...

I've taken to using my smart phone but leaving it at home as much as I can, I only take it out if I'm going out for a long period of time now and I'll take my dumb phone so my wife can contact me if possible.
