Samsung may announce the Galaxy S IV on March 15
The Galaxy S IV is then expected to hit most European markets by the end of April, while the Americas, Australia and Africa are said to get it sometime in May or June - a two month delay similar to what we've observed with previous Galaxy S launches.
As most of our readers surely know, the GS IV is expected to be one of the hottest Android phones of the year, due to the great popularity of the series. Unofficial sources claim that the new model will step things up with a larger, 5" 1080p display, the recently-announced Exynos 5 Octa SoC, 2GB RAM and a 13MP camera. All of this will surely be powered by the latest version of Android, which is 4.2 Jelly Bean. Of course, don't forget about Samsung's own TouchWiz user interface, which will probably also get an overhaul of its own. The first versions of this UI were pretty poor in terms of design and responsiveness, but Samsung made a big step forward with its latest iteration last year - the Nature UX, so we're looking forward to seeing what new stuff the manufacturer has come up with for 2013.
