It's not a binary normal/abnormal question. Smartphones triggered a rapid, extreme, and long duration shift in attention away from physical reality.

Imagine taking a person today and forcing them to use virtual reality for the average amount of time one looks at a smartphone over a 24 hours period.

You would see an even greater loss in overall happiness, increase in mental illness etc . We're evolving much too fast. The mind can't keep up. So it falls apart.
