I think if you are someone’s emergency contact than leaving your phone in a kitchen safe is irresponsible. My strategy for fighting phone addiction always allows me to hear and answer a phone call because it’s the defacto method of communication during emergencies.
During the day if I’m working I’ll put my phone into kitchensafe for like 30 or 45mins so I can focus on the task without looking at my phone.
As far as calls are concerned if they are important they’ll probably leave voicemail and I’ll get back to them right away
Lastly I usually keep my phone locked at night before going to bed as It helps me stay away from it
