Samsung unveiled its latest smartphone at the iconic Radio City Music Hall in New York City on Thursday, with software features aimed at helping the electronics giant win the smartphone battle.

The launch of the flagship Galaxy S4 is not significantly different design-wise from its predecessor, the Galaxy S3, but its new software sets the bar high for its rival Apple to beat.

One new function is called 'Air Gesture,' which allows users to navigate their phone without actually touching the device.

The phone also features a function called Samsung 'Smart Scroll', which enables users to scroll without touching the screen. It tracks the users' face to tell where they are looking.

'Smart Pause' is a similar feature that tracks when a user is watching something on their phone so that it can pause the media when a user looks away.



Samsung did not reveal a price for the new handset, but carriers confirm that it will become available in the coming weeks. The device, which has a 5-inch display, will come in both black and white models.
