Samsung has pushed a Samsung Mobile UNPACKED 2012 app on Google Play which, surprise surprise, contains a clear reference to the Galaxy S3. The app itself is fairly bland (given that nearly half of the user reviews give it only one star out of five).
Oddly enough, there's no word about the "next Galaxy". The app provides details about all the previous Samsung Mobile Unpacked episodes, the event schedule (which will happen on the 3rd of May in London), the event location and transportation for that event (bear in mind though it is an invite only event), the teaser and a link to the live stream.
Unfortunately, the app won't change your life. Not only it doesn't appear to work on non-Samsung devices, but as one reviewer puts it " But there is no much info present and it says that wait until may 3rd to get the info revealed.But i don't know why the app size is so huge 14MB with nothing much in it?"
To date, there has been a video of the phone (via a Vietnamese website), a formal confirmation that Vodafone will sell it, a teaser website, a hint of a Samsung equivalent of the iCloud (called the S-Cloud) and a rumour about a possible eye tracking technology.
