Is the order not to use cell phones in the classroom enforced?

Since one year, in schools across the country, cell phones are not allowed in classrooms. A measure of the Ministry of Education that forces students and teachers of 9-year and secondary schools in the country to focus only on learning and which seems to have calmed the teachers down a lot. Mobile phones were often used as a means of blackmail against teachers who, fearing the videos that often ended up on social networks, had also banned the request for an account in classes. But a year later, is this order enforced? 31 Minutes went to schools where it turns out that this order is not always implemented. It is violated openly and no one is punished for it.
