I carry my smartphone with me but I keep it on DND most of the time unless I'm expecting a call or an email.

That way I get the best of both worlds: lack of constant interruptions and the ability to use important features such as maps, camera, etc. when I need.

I always keep mine on DND, but I find that I impulsively check news sites and social media. It puts me in this constant state of never really being bored, so I'm less likely to pursue new and interesting things (reading books, practicing hobbies, exploring new interests).

My smartphone is used mostly for the combination of checking emails (if necessary sending a quick reply that I'll follow up on later), and predominantly as a portable entertainment device.

I have setup SOME trusted contacts (mostly family, skilled coworkers who understand decorum) to pierce the DnD veil.
