> "relax" or "do not disturb" modes - curious if that actually works for anyone?

Ever since I've owned a smartphone, they have been on "do not disturb" 24/7. People that know me know they won't reach me directly, but that I will call them back eventually. I do have a couple of voice calls every day; I schedule them ahead of time based on my own actions, and set an alarm to take out the phone.

I am typically involved in something and I don't want to be disturbed during it; it may just be thinking, or reading, or actually talking to a human being present with me; why would I ever want to be disturbed? I only check my phone when I want to actively perform some task with it anyway, e.g. to look at maps, and then I put it away again. I don't mind carrying it around and needing to use it increasingly for tickets and such. I do not experience this as "self control". I don't have the urge to take out my wallet or keys or umbrella unless I need them either. Why would I.

I typically (also) carry a paper book to read on public transport or in cafés.
