Head teachers in the first London borough to introduce a ban on smartphones in schools have reported that pupils are happier and better behaved as a result. The move reflects growing concern among educators and parents about the impact of smartphone and social media use on children's mental health, attention spans and classroom conduct, and could serve as a model for other areas considering similar restrictions.

The article does not provide further specific details, figures or direct quotes from the heads involved beyond the headline claim, as the full text of the report was not available. It nonetheless points to a wider debate over school phone policies, which has gained momentum in the UK amid calls for tighter national guidance on device use among children.
