This is a valid point, and the people I talked to tended to be younger. I assume older people don't lock their devices? Or maybe its a regional thing? In German

This is a valid point, and the people I talked to tended to be younger. I assume older people don't lock their devices? Or maybe its a regional thing? In Germany I (anecdotal) have met maybe a handful of people under 40 who didn't lock their phone and one under 30 of a 100+ people.
