Flossie McShea from Devon says she saw a shooting, a beheading and porn and that other students ‘show you their screen without invitation’

A 17-year-old girl who says she was exposed to horrific images and videos including porn, a shooting and a beheading on a smartphones during the school day has joined a legal action against the education secretary.

Flossie McShea, from Devon, says she also received threatening messages while at school, as she put her name to a judicial review in an attempt to get smartphones banned in schools in England.

Will Orr-Ewing and Pete Montgomery first notified the education secretary, Bridget Phillipson, in July that they would pursue legal action, arguing that current guidance, which allows headteachers to decide how smartphones are used, is unlawful and unsafe for children.

“Videos were going around all the time,” McShea recalls of her time at secondary school from year 7 onwards. “My parents were strict at home but at school people can airdrop you videos or show you their screen without invitation, to see your reaction.
