i don't even do sms on my 'dumb' phone.

when the phone makes a noise, it's either low on battery (or, if it was plugged-in, fully charged), an alarm or timer i set, or a very high probability of being a legit call (the carrier has reasonably-effective blockers for spam, bots and spoofed origin calls).

Personally I keep my installed apps to a minimum, heavily use Firefox on mobile with uBlock Origin, and heavily curate what's allowed to send notifications and when, so my phone is quiet and not distracting but there when I want it/need it

At this point it's like the Onion article that they release after every school shooting about how nothing can be done to prevent it in the only country where it occurs regularly; the data raping and pillaging that goes on in the US despite other countries having passed basic common sense privacy and control laws...well too bad you can't afford the lobbyists to pass it, Poor.
