Samsung is set to launch a device in its flagship best smartphone range, expected to be named the Galaxy S4. It follows the S3, a handset that has sold more than 40 million. The Galaxy handsets are seen as the contiguous competitor to Apple's iPhone. Analysts forecast software that tracks where users are looking and routinely scrolls down the page as it is read, without it being touched.
There is also likely to be a souped-up camera and processor. But crucial to Samsung's prospect success, analyst’s state is how the South Korean company plans to turn its strong position in the smart phone market into greater success with other devices such as tablets. Prior to Thursday's launch in New York, Samsung has unleashed a huge advertising campaign, with a series of videos involving a small boy tasked with looking after a top secret box.
