Point function allows scrolling of the eyes, as was the rumor. By cons, when you play a video on the S4 and you leave the eye, it will automatically pause. Health S application count your steps, estimate the calories you burn in a day, while your finger will serve stylus functions View Air and Air Gesture: waving your finger a few inches from the screen you will be able to interact with it. The S4 will also be offered with a sort of "flip cover", but also with an optional strap to analyze your sleep and heart rate. Good by cons, to give you an idea of the thing, when you take the One HTC in hand, you really feel like to hold a sacred Smartphone, well finished, and last generation. When you weigh the sub-S4 Galaxy, you feel you hold in your hand a Galaxy S3 improved a little.
The Smartphone will be launched around April 2013.
