Exactly after one week from now, Samsung will finally launch its next-generation Galaxy S smartphone – the Galaxy S4 – at a media event, scheduled to take place in New York, March 14. But regardless of that, the so-called rumor mill surrounding the upcoming device doesn’t seem to calm down just yet.
Following a report saying the Samsung Galaxy S4 will stick to the traditional plastic body, “despite rivals opting to use metal and other premium-feeling materials,” a new report has appeared online Wednesday with a set of screenshots, claiming to be of an American variant of the next Samsung flagship smartphone.
The leaked Samsung Galaxy S4 screenshots, published by the tech blog GSM Israel, apparently have confirmed a number of key features of the device that have been widely rumored of late. The screenshots have revealed that the Galaxy S3 successor will feature a 5-inch Full HD display with screen resolution of 1080 x 1920 pixels (441 ppi), a 13-megapixel primary camera, 2GB RAM and a Quad-Core 1.8GHz processor with LTE on board.

As SamMobile has pointed out, the leaked screenshots belong to an American variant of the Samsung Galaxy S4. That said, there is still possibility that the international variant of the smartphone will be powered by an Exynos Octa CPU.
‘Smart Scroll’ Confirmed!
Reports surfaced a couple of days back suggesting that the new Samsung Galaxy S4 will include a new eye-tracking feature that can track users’ eyes to scroll through pages. Now, the new reports featuring Galaxy S4 screenshots have confirmed that the device will indeed have the ability to allow users scroll up and down a page with an eye movement, thanks to a new feature called “Smart Scroll.”
How it will work - A camera on the front of the handset is able to focus on the user's eye.It can then calculate where on the screen they are looking - and automatically advance pages when they reach the bottom, for instance

Apart from that, the Samsung Galaxy S4 will also have features like “Smart Pause” that will freeze any multimedia playing on the device when the user turns his head away, “Smart Rotation” that will adjust the screen orientation according to the user’s angle of sight and “Smart Stay” that will disable screen timeout when the device detects that the user’s face is watching the screen.
