The Samsung Galaxy S2 is finally getting caught up on a much-anticipated Android system update, with the device now receiving Android 4.1.2 on the AT&T network, months after the Galaxy S2 Skyrocket variant received its Jelly Bean update.

While AT&T has yet to make an announcement about the update, many Galaxy S2 owners report that the operating system is now available through Samsung Kies. It remains uncertain whether the update will also be made available over the air. Samsung Kies allows users to download the update and install Android systems and updates through a computer, as opposed to having the software be downloadable directly from a device. However, we expect the OTA update to be available soon.

Galaxy S2 owners who have already received the update don’t seemed to mind if they have to computer-install the new system instead of having a direct download, as they have been waiting quite a while for the update to hit their handsets.

Android 4.1.2 Jelly Bean will be the third operating system to run on the Galaxy S2. The device was released in May 2011 running Android 2.3 Gingerbread and was upgraded to Android 4.0 Ice Cream Sandwich in December 2012 for AT&T.

Android 4.1.2 brings to the Galaxy S2 up to build number UCMD8 and provides such enhancements as a smoother user interface and improvements to multitasking, notifications and various stock apps like the browser. We will likely see improvements to the device’s camera and calendar and the introduction of Google Now, among many other updates.

As the AT&T Galaxy S2 is switching over to a whole new operating system, updates stand to be significant. However, seeing that the Galaxy S2 is a considerably old device at more than two years on the market, adopters should be mindful that it may be prone to having issues with the more current software.
