It depends on whether you hold a world view where every person is valuable and needs help and understanding to become their best self or one where there are good and bad people and the baddies need to be punished and locked away so everyone else can live their life in peace.

It is the correct term. I would just like to know who came up with that?

I also do that but I think „Handy“ is still the most common term. When there is any need for clarification for what you mean by „phone“, „handy“ will clear it up for everyone.
