In a move which marks the latest development in the Apple-Samsung battle for dominance in the smartphone market, Samsung unveiled its much-anticipated fourth-generation Galaxy handset - the Galaxy S4 - at a gala Thursday-evening event at the Radio City Music Hall in New York.

The event - which was attended by 3,000 people, including Samsung's partners from all across the world - was broadcast at the Times Square, which is close to Apple's flagship store.

The unveiling of Galaxy S4 in New York was the first overseas smartphone launch which South Korea-based Samsung has hosted in North America; with the event coming at a time when the company leads the global smartphone market, even though Apple still continues to be the dominant player in the lucrative US market.

According to some of the early reviews about the Samsung Galaxy S4, the smartphone lives up to predictions.

It is a thin as well as light handset which features a 5-inch super-bright full HD resolution screen; a powerful processor; and a 13-megapixel camera.

The handset also boasts some of the much-awaited features such as an eye-tracking screen which scrolls down automatically when users read to the bottom of the page.

Despite the fact that Samsung did not officially disclose the pricing of the Galaxy S4 at the event, it has been reported that the handset is scheduled for launch towards the end of April with 327 carriers in 55 countries.
