As a millennial I never understood any time I hear about this sort of thing since I remember phones were strictly forbidden and teachers would take them from you. Not sure if California was different from Florida, but I could have sworn Florida passed similar legislation if I am not mistaken.
Only after school were teachers laxe for obvious reasons. During lunch time we were not expected to use phones.
