Samsung Electronics is reportedly rolling out Android 4.1.2 software upgrade to the GALAXY S II GT-I9100G model. But dont get to excited about it just yet as this rollout is underway in stages and it may not be available in your area (country, network operator).
The upgrade is available through Samsung Kies or OTA (over the air) and the new firmware build should be JZO54K. SamMobile was kind enough to provide a few screenshots too.
We can not confirm at this time any country or any network operator where the update is available, however if any of our readers manages to pull this off and successfuly install it please do let us know. Enjoy
