Our middle child (aged 12) has an Android phone, but it has Family Link on it.
Nominally he gets 60 mins of phone time per day, but he rarely even comes close to that, according to Family Link he used it for a total of 17 minutes yesterday. One comes to the conclusion that with no social media apps, the phone just isn't that attractive.
He seems to spend most of his spare time reading or playing sports...
Just one of the many joys of parenting :)
If it's a concern, parents can prevent or limit their children's use. If all this were being done to prevent consistent successful terrorist attacks in the US with tens of thousands of annual casualties, I'd say okay maybe there is an unavoidable trade-off that must be made here, but this is so absurd.
