A survey of thousands of pupils, teachers and parents has found struggling students are more likely to come into contact with potentially harmful content on their phones compared to their better performing peers.
The University of the West of England study found pupils who categorised themselves as struggling academically were at greater risk of seeing content on topics like self harm.
It also found parents underestimated the types of harmful content their children were viewing and that there was support for stricter rules on phones in schools.
Researchers found "toxic" aspects of smartphone use and said better conversations around the negative impacts of devices were needed.
