Need to know – Samsung Galaxy S3

Samsung Galaxy S3 – Android 4.0 Ice Cream Sandwich

Unsurprisingly, the Samsung Galaxy S3 comes with Android 4.0 Ice Cream Sandwich out of the box, skinned with Samsung's polarising TouchWiz interface – pre-loaded apps include Dropbox and Flipboard.

Samsung has packed the Galaxy S3 with extra features; Smart Stay uses the front-facing camera to detect whether or not you're looking at the screen, and prevents it from dimming accordingly.

Smart Alert triggers notifications when you pick the phone up, while Siri-baiting S Voice gives you full-featured voice control over the phone's functions. You can use it to activate the phone, for example – or even switch the camera on and take a photo.

As well as setting its sights on the iPhone's Siri, Samsung is gunning for AirPlay with the Galaxy S3's AllShare Cast TV mirroring feature. The phone's video skills also include Pop Up Play, for viewing picture-in-picture video while you're in another app.

Finally, S Beam uses the phone's NFC features for data sharing by touching your S3 with another S Beam-equipped phone – like, say the Galaxy Nexus.
