Just hours ahead of Samsung’s official unveiling of the Galaxy S IV there’s an avalanche of leaks being unleashed upon us, all demonstrated on the Chinese GT-I9502 — which according to some reports will not be the real deal. But let’s cut to the chase: the lock screen on the S III and Note II (and pretty much all other Galaxy phones) had a nature theme to it (inherited from TouchWiz Nature UX) and they mimicked water droplets. This year it looks like Samsung stuck with the nature theme but the lock screen appears to be a rainbow.

Much more interesting than that is the floating touch, present already on phones like the Sony Xperia Sola, which allows the user to interact with the screen of the phone without physically touching it. Instead, just hovering over the display can trigger an action, pretty much like AirView on the Note II, with the S-Pen.

LG just announced eye recognition for smart video on the Optimus G Pro and it looks like the exact same principle will exist on the Samsung Galaxy S IV. Look at the screen and it plays the video; look away and it pauses; look back and it resumes. Their take is SmartPause.

Check out all those demonstrated in the leaked videos below and remember to check back with Pocketnow for our comprehensive coverage of the launch event.
