The iPhone Killer has been unleashed in London yesterday. The Samsung Galaxy S3 which was finally revealed at the Samsung Mobile Unpacked 2012 event, is expected to dominate the Android smartphone market with its huge 4.8-inch HD Super AMOLED display with 1280x720p resolution.

The phone features an 8MP camera, 1GB ram and a powerful Exynos 4 Quad (1.4GHz) processor. The Samsung Galaxy S3 follows its predecessor - the Galaxy S2 - which was the best-selling mobile phone in the world.

The coolest new feature is the eye-tracking control, which keeps the phone awake when it sense that your eyes on the screen. If iPhone 4S comes with Suri, the Samsung Galaxy S3 has the S Voice - which would allow you to search for anything by voice command. Samsung says S Voice can be used while driving - as it can reply to you out loud.

Another feature is that you have the option of charging your phone wirelessly if you dish out on a separate wireless charging kit. Your phone can charge while in your pocket!

It also has an NFC chip which will allow you to share content just by tapping the phones together. With NFC in partnership with Visa, this may also be used as a virtual wallet - where you can just tap to pay.

The phone is expected to launch in Europe on May 29. Those in the States will have to wait another month to get their hands on this device - as it is expected to launch here in June.
