South Korean mobile phone maker Samsung has reportedly started to push out the Android 4.1.1 Jelly Bean OS upgrade for the Galaxy S III flagship phone, with users in Poland being the first to receive it. Users in Eastern European countries such as Croatia, Macedonia, and Serbia should also see the update available for download through the Samsung Kies application, reports suggest. Unfortunately, it appears that users cannot download the new update over-the-air, though it should not be too long before they will be able to do so as well. The update weighs 282.5MB and comes with all the features Google has unveiled so far for the new platform flavor. Project Butter is included in the mix, which means that users will take advantage of increased performance capabilities, with everything moving smoother and faster than before. The settings menu has been reportedly reorganized; there is a new Notifications bar available for users to take advantage of, as well as the appealing Google Now feature, which provides users with snippets of information on their homescreen. Following the update, Galaxy S III users will also take advantage of a resizable Pop-up play screen, as well as of two Homescreen modes, the guys over at SamMobile report. The new update will arrive on devices as firmware PDA I9300XXDLIB CSC I9300OXFDLI1 MODEM I9300XXDLIB, it seems. As one can imagine, Samsung will most probably deliver the update in stages, meaning that only some users will receive it now, and that the rest of them will have to wait a bit longer for it to arrive. Earlier this month, Samsung said that the update would be delivered only in October, but it appears that it was able to start the roll-out sooner than that. Handset owners in the aforementioned countries are encouraged to check for the availability of the new software both on their handsets and via the Kies software. Before kicking the update process, users should also consider backing up all data on the phone, just to make sure that nothing is lost. They should also make sure that the battery inside their handsets has been charged at least at 50 percent.
