Brazil's President Luiz Inácio Lula da Silva on Monday signed a bill restricting the use of smartphones at school, following a global trend for such limitations. The move will impact students at elementary and high schools across the South American nation starting in February.

School districts in Washington state would be required to enforce policies that restrict student use of phones under a new bill proposed Monday.

The rule was enacted on Monday in order to drive people away from excessive phone use because "humans are born to live in community".
