Moreover, some tweaks have been made to the camera app, also notification has been revamped, a Siri-like feature called Google Now and Android Beam have also been introduced in the new operating system. The new OS also launches a faster user interface enabled by "Project Butter."

Meanwhile, Samsung has notified users that it will be offering Jelly Bean update for "eligible" devices. The Korean giant has released its statement to folks at PocketNow.

As the world's largest smartphone manufacturer, Samsung, leads the Android community with best-in-class devices like Galaxy S III, and is creating new device categories with products like the Galaxy Note. Samsung has delivered the most Nexus-branded lead OS devices and we are pleased that Google will be bringing Samsung Galaxy Nexus and Nexus S customers the first experiences of Jelly Bean on a handheld device."
