If a renowned Samsung fan site is to be believed, Samsung could be first with the Jelly Bean update, with new firmware planned for the Galaxy S III, Galaxy S II, Galaxy Note and the unannounced Galaxy Note 2.
SamMobile is reporting that the Galaxy phone maker is close to finishing the update, which would advance the software on its best-selling phones to the Android 4.1 platform. It reports that the Galaxy S III firmware has been successfully tested internally, and that a public build will be ready for the telcos once Google has signed off on it. By their estimates, the updates should begin rolling out at the end of Q3, or September for those of us who don't speak in quarters.
The Galaxy S II and the Galaxy Note are in the internal testing phase, but this is running smoothly. This means that the update for these models will be slightly later than for the Galaxy S III, but not too far behind it.
As we reported yesterday, the Galaxy Note 2 is expected to launch at an event in Berlin at the end of September, and SamMobile believes there is a chance that Samsung will try to ship this new model with Jelly Bean pre-loaded. If this isn't the case, an update will be made available "a couple of months after".
Of course, all of these update timings are subject to the approval of the local carriers, too. If Samsung does begin to finalise its Jelly Bean update at the end of September, the telcos would need a testing period of their own, and this could add several weeks to the wait for end users.
