Samsung officially revealed a teaser photo of the Galaxy S4

Samsung's Mobile US Twitter account has posted this picture showing what appears to be a smartphone.  Yes, you have guessed, it's the Galaxy S IV that will be announced this Thursday.

It looks almost exactly the same round design as the leaked photos we saw yesterday.  But what we do miss is the speaker, camera and of course the level sensors. 

The Galaxy S4 is most likely to have the Smart Scroll feature that lets the phone sense a user's eye movements to scroll up and down. This, along with the Smart Pause was reported on the NY Times more or less a week ago, which somehow makes it a bit credible. It will feature an Exynos Octa made by Samsung in place of the previously and widely-rumored Snapdragon chipset. A future upgrade to Snapdragon is also possible. It may also have a plastic (polycarbonate) build, which is being panned by some supporters who are expecting an aluminum exterior. These are only some of the more credible features that the S4 will and may have.
