Samsung however had promised it will actually bring the update to the device, and is now closer to delivering on its promise. Why? The company has published the manual for Android 4.1 Jelly Bean on its official website and while that doesn’t necessarily mean the update is soon coming, it is a good hint at that.
Androird 4.1.2 is expected to arrive on 2011 devices like the Samsung Galaxy Note and the Samsung Galaxy S II in January to February.
