Can a teacher take your phone away?

I do not think this is a question for homework but if you are caught, during a lesson or in school, with a electronic device then because of the laws they are legally allowed to take your phone away. They don't do it because they want too, they do it so that you could pay attention to education and get a good career one day if you have good grades.

If you are caught using your phone in class, teachers are legally allowed to take the phone for that class period or even until the end of the day ... However, a teacher cannot legally look at anything on your phone, that is an invasion of privacy.

Explanation:

That is the legal answer, however whenever a teacher tries to take away your phone, you can simply say "This phone is legally under my parents names, and since they do not go to this school, taking my phone would technically be theft." which was also legally correct.
