Brazil’s President Luiz Inácio Lula da Silva on Monday signed a bill restricting¹ the use of smartphones at school, following a global trend for such limitations².

The move will impact students at elementary and high schools across the South American nation starting in February. It provides a legal framework³ to ensure students only use such devices⁴ in cases of emergency and danger, for educational purposes, or if they have disabilities and require them.

“We cannot allow humanism to be replaced by algorithms,” Lula said in a closed ceremony at the presidential palace in the capital, Brasilia, adding that the bill “acknowledges⁵ the work of every serious person in education, everyone who wants to take care of children and teenagers in this country.”

In May, Fundacao Getulio Vargas, a leading think-tank and university, said Brazil had more smartphones than people, with 258 million devices for a population of 203 million Brazilians. Local market researchers said last year that Brazilians spend 9 hours and 13 minutes per day on screens, one of the world’s highest figures.

Education minister Camilo Santana told journalists that children are going online at early ages, making it harder for parents to keep track of what they do, and that restricting smartphones at school will help them.
