Owners of Samsung Galaxy S2 on Three UK waited patiently for an Android Jelly Bean update, and now the wait has finally come to an end.

Three UK has started rolling out the Android 4.1 Jelly Bean update for Samsung Galaxy S2 devices over the air (OTA).

Samsung release the Android 4.1 Jelly Bean update for Galaxy S2 unlocked devices in early February, but as the carriers always take a long time to tweak the software a little to give their own flavor, mobile carriers across the world are taking time to roll out the software update.

By releasing the Android 4.1 Jelly Bean update, Three UK has gone ahead of U.S. carriers like Verizon, AT&T and Sprint who are still waiting to roll out the update.

After getting the Android 4.1 Jelly Bean update, Samsung Galaxy S2 will move from Android 4.0 Ice Cream Sandwich.

The update will bring so many new and amazing features to the device that will enhance the performance and the user experience both.

The update will enhance the smartphone's performance by giving it better notifications and improved battery life.

The Android 4.1 Jelly Bean update will also bring the most talked about feature of the Jelly Bean update -- Google Now - to Galaxy S2 devices.

Google Now tells the user about the weather, traffic of the city and other things like train timings or live scores. Apart from Google Now, the firmware update also improves the user interface (UI) of the devices with the help of smooth Project Butter. The Android 4.1 Jelly Bean update also allows the Samsung Galaxy S2 users to taste some of the TouchWiz features that debuted on the Samsung Galaxy S3, like Smart Stay, Direct Call, Pop-up-play, or Lockscreen shortcuts.

The Samsung Galaxy S2 devices on Three UK can be updated to Android 4.1 Jelly Bean over the air or the firmware can also be downloaded via Samsung Kies.
