In the biggest challenge to date to Apple’s smartphone dominance Samsung on Thursday launched the Galaxy S4, touting several features not available on iPhones.

Due to go on sale in late April in 55 countries, the new device sports a 5-inch HD AMOLED screen with a density of 441 pixels per inch.

It includes a 13MP and 2 MP dual camera capable of taking shots with both lenses simultaneously while recording sound and attaching it to the image. Dual video recording is possible, Samsung said.

The phone will run on Google’s Android operating system, with extra layers of Samsung software, which the South Korean electronics giant hopes will differentiate it from both Apple’s iPhone and numerous Android rivals.

Other notable features include the S Translator, which converts spoken and written language on the fly, Smart Scroll and Smart Pause, which track eye movements to automatically scroll the screen or pause videos, and Air View and Air gesture, which allow users to control icons by hovering their finger over the screen, and accept calls by waving their hands. An app called S Drive uses voice recognition to control navigation and communications while driving.

The phone will ship with the latest version of Android, known as Jelly Bean, and will have a choice of 16, 32 or 64 gigabytes of internal storage, as well as a micro SD slot for adding up to 64 GB of card memory. It has 2 GB of RAM memory and a 2600 mAh battery.

Analysts have cast the S4 as the most significant challenge to the iPhone’s dominance, based on Samsung’s powerful market position and the popularity of its S3 predecessor.
