I will agree. Because if teachers allow using the phone, there will be a separate rule when using the phone. For example, if using it without the teacher's permission, it will be warned the first time and the second time will be confiscated. So I will say yes. And that is all.

The first consequence is the situation that students are too passionate about the phone but forget to study, neglect in studying, cause disorder in the classroom, and lack of knowledge because of not paying attention. Listening to lectures, ... Since then, leading to poor academic results, parents cannot find out the cause, pressure to scold them even more, which makes them more and more immersed in the mobile phones, considering it a part of life, are so vicious that it is difficult to completely solve the problem. Excessive use of mobile phones also leads to negative health problems, such as eye defects, astigmatism, nearsightedness, and even blindness. Too focused on the phone but away from reality, away from society is also one of the causes of depression, distraction, decreased ability to think creatively, people become weak and sensitive to external impact.
