Previous rumors claimed Samsung will give up on its traditional home button and navigation keys on the next Galaxy S model.
In addition, rumors also pointed to the integration of an S Pen stylus.
But Korean publication Digital Daily now reports that Samsung actually decided to keep the home button and that the S Pen Stylus should remain specific to the Galaxy Note family.
The same site recently wrote that, in addition to the usual functions, the screen of the device could be operated with gestures without touching the screen, with a similar process used by Sony’s Xperia Sola that featured the “floating touch” navigation.
Rumored specs of the Galaxy S IV include a 4.99-inch full HD 1080p AMOLED display, a 1.8GHz eight-core Exnoys 5 Octa processor and a 13-megapixel camera.
Recent speculation suggested that Samsung could announce the Galaxy S4 on March 15, after the MWC 2013.
