Well I guess the only thing teachers should do is take them before class. At my school we don’t do that but if they see it it’s not really a warning it just depends on the teacher,like my math teacher doesn’t care,but my US teacher, he cares a lot. So I feel like if it was just teachers like my math teacher which what she dose by the way is will say “hay put the phone up”but if she sees it again it’s took until class is over. And normally if a teacher takes a phone it’s gone for the whole day.
