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.
The problem is that phones are intentionally made to be addictive. There isn’t always a responsible way to use them at all if you have any apps other than ‘calls’.
Tackling the manufacturer’s and software designers would be more useful for everyone than an outright ban for children. Banning manufacturers and carriers from preloading and bloating phones with social media apps and any games would be a start. Platforms actually stopping (young) children from signing up might also help.
