Yeah it is not always simple, we need empathy when dealing with this kind of problem, not brushing off people that may be having difficult times.

It's not "brushing off" to suggest that someone use their phone less. If picking up the phone is an automatic behaviour to fill moments of dullness, then that's a problem.

All the empathy in the world won't save anyone here. On one side of that screen is you, alone. On the other side are an army of designers, developers and behavioural experts whose job it is to keep you looking at the screen for as long as possible.

I don’t disagree with you on a personal level, but it is worth noting that “social disgust” is what has driven down tobacco rates as a population, even if it’s perhaps less effective for any one individual than empathy, etc.
