Samsung unveiled its new Galaxy S4 smartphone at the Radio City music hall in New York, with a performance from a tap-dancing child and a story about a lovestruck backpacker to show off its new features.

The highly-anticipated smartphone - the fourth generation of the Galaxy S - is likely to pose a major threat to Apple and its popular iPhones.

Samsung unveiled a host of new features with its S4, including a dual camera function that allows users to take simultaneous photos and videos using both rear and front cameras, which can then blend the pictures together.

A story album function allows users to create a photo album which is personalised around a timeline of special occasions and events in their lives, and lets them manage associated content such as comments on social networks, locations and weather information.

Group play lets people enjoy music, photos and games with people around them, and the Samsung "smart pause" function allows users to control the screen using their eyes.

Paul Thompson, managing director of mobile advertising company BlisMedia, said: "Again the S4 is setting the benchmark on how to really integrate a mobile device into your everyday life."

The handset is due to go on sale around the world between April and June this year.

However shares in Samsung fell as much as 1.3% in early trade in South Korea immediately following the launch.

The stock under-performed the wider market which was trading roughly flat.
