Putting an end to a long wait, Samsung has started rolling out the official Android 4.1.2 Jelly Bean firmware update for the International Samsung Galaxy S2 (GT-I9100) Wednesday.
Although it was reported earlier this month that the South Korean tech giant would release the firmware update in February, a Wednesday report from SamMobile has revealed that the update had landed much earlier than it was expected before.
Considering the new Jelly Bean update for the Galaxy S2 as “by far the most major update given to a smartphone yet,” the report also has stated that in the latest firmware update “Samsung has completely ditched the old UI and has given the new Nature UX Interface, which is the same as the one being used in the Galaxy S3 Mini and the Galaxy S3.”
At the time of writing this article, the only region where the Android 4.1.2 Jelly Bean firmware update for the Galaxy S2 (GT-I9100) was accessible is Spain. Other regions are likely to receive the update in the coming weeks as it is rolling out in phases.
