The Galaxy S3 was one of 2012's best selling mobile phones, coming close to ousting Apple's iPhone 5 as the year's best seller.
The S3 stormed past the 10 million sales milestone within weeks of launching in July 2012, the 20 million mark in September and the 40 million mark in January this year.
Eager to repeat the S3's success, Samsung's loaded the S4 with a host of innovative business minded features.
These include the S4‘s Air Gesture and Eye Scroll services. Air Gesture lets users do things like change the music track they're listening to, scroll up and down the web page they're viewing, or accept a call with a wave of their hand. Eye Scroll is a nifty feature designed to let the S4 know when the user has finished reading text on the screen and automatically scroll down.
Sadly though the first run of Galaxy S4s will not feature the company's Knox security services.
Knox was unveiled earlier in the year and offers similar services to BlackBerry
Balance, letting users set up separate work and home areas on the phone.
