One in four teenagers and almost one in five adults has admitted to using their smartphones during performances, new research has suggested.
People without smartphones are less likely to keep their phones turned on during a play or film, Ofcom, the government's communication's watchdog, found.
According to Ofcom, using phones to surf the web or post messages on Twitter raises issues of "social etiquette and modern manners", wireless communication device users may be interested to learn.
James Thickett, director of research for Ofcom, said: "I think what we have found before is that teenagers have always been more likely to use mobile phones in cinemas and theatres. What we are finding now is that for smartphone users, it is much, much higher, but adult smartphone users as well.
"So it is not just about adults and teenagers having different values, it is about technology driving the values towards the way you behave in social situations."
