Nowaday,teenagers mostly have their own smartphones.Using smartphone is not bad because you can search informations,study or relax.But,bring them to schools is not nice.It is not safe for you.Why?Firstly,if you bring an expensive one,you might be robbed and the school you're studying won't have the responsibility of this.Secondly,if you are running,you may fall and break it.Thirdly,you will be scold when you lend your phone to your friend without any good purpose.Not only that,you may use your phone in class and that will affect the other classmates.So,I say that bringing your phone without purpose is not good,but bringing it to call your parents to take you home is still alright.
