A new UN report raised concerns on Wednesday about the excessive use of smartphones, calling for them to be banned in schools worldwide. According to the UN's education, science and culture agency UNESCO, the over-use of mobile phones impacts learning.
There is no way to do that without giving the school remote control over the phone, which would be a security and privacy violation.
I was moreso referring to dealing with the dark patterns that apps use in general, not the school doing that.
