Samsung Galaxy S4, the most anticipated smartphone of the year, was finally released at the company's Unpacked event held at Radio City Music Hall, New York, on Thursday evening.

The South Korean technology giant premiered its latest flagship phone with a 5.0-inch Super AMOLED full HD resolution display, 2 GB RAM, Samsung Exynos 5410 Octa-core processor, Android v4.2.2 OS (Jelly Bean), 13.0-megapixel camera and 2.0-megapixel front camera.

One of the main attractions of the smartphone is Smart Scroll, an eye-tracking feature that allows users to scroll automatically without having to touch the screen.

Galaxy S4 will be available globally by the end of April. Samsung said that all major US service providers will sell the smartphone. The company also revealed that Galaxy S4 would be available in 155 countries including India.

The pricing of the new smartphone is still under wraps.

According to The Times of India report, the device will be available in India around end of April or early May.

 JK Shin, president and head of IT & Mobile Communications, Samsung, said, "With the Galaxy S4, Samsung is again going to enhance the way we live."

Following the launch of the product, shares of Samsung Electronics Co Ltd fell by 2.4 percent in Seoul on Friday.

Analysts said that the new device might have dissapointed some investors who had huge expectations following months of rumours related to its features.

"It's just that investors feel technical smartphone upgrades are flattening out," Bae Seung-Young of Hyundai Securities told AFP.

The company's stock price has been at a steady position this year, while Apple's stock price declined by 20 percent.

According to AFP report, Samsung captured 29 percent of the smartphone market as against Apple's 21.8 percent in 2012. It also had 23 percent of the overall mobile phone market which is ahead of Nokia's 17.9 percent.
