‘Put learners first’: Unesco calls for global ban on smartphones in schools - eviltoast
Major UN report issues warning over excessive use, with one in six countries already banning the devices

I personally think that responsible smartphone use should be learned and practiced, rather than outright banning them.

I think this shows that adults are terribly addicted to their devices and think if they can’t stop using them, children won’t either. They certainly can’t teach how to use phones responsibly if they can’t do it themselves. Unfortunately for children the result is an outright ban.
