I see folks, head down scrolling, as they shop, walking the sidewalks, sitting in their car and even with it propped ion the wheel as they drive. My phone?? In my pocket generally when I'm out unless someone calls or I need to call. Not interested in browsing the net, watching tv/movies, playing games or trading random messages. I'd rather watch the world around me. My brother's kids will retreat at family gatherings to corners with theirs rather than associate with the wider group.
I have read that there are some studies that indicate excessive smartphone use can rewire parts of the brain similar to a chemical addiction.
