Can't speak for the rest of the country, but in our district smartphones were allowed for a couple years. I don't know the rationale about allowing them in the first place, but it happened in 2020. It took them two years to decide it was an unmitigated disaster and they promptly re-banned all electronics. No music players, phones, headphones, etc. Get caught and it gets confiscated and your parents have to come retrieve it.

Maybe that's draconian. But maybe it's just good sense -- our high school is close to #1 in the state for academic performance, so they are doing something right.
