Official Samsung Galaxy S2 I9100G Update to Android 4.1.2 Jelly Bean Firmware is now available

The I9100G variant of Galaxy S2 has officially received the new Android 4.1.2 Jelly Bean update. Samsung pushed today the official update for various devices all around the world and you should wait until the OTA notification is sent. Also, you can easily check for the update using the Samsung KIES software.

Android 4.1.2 Jelly Bean for Galaxy S2 I9100G will bring a new UI, the Nature UX which is the same one that was launched with the Galaxy S3,Galaxy S3 mini, Galaxy Note 2. You will get for the first time the Project Butter software which brings a smooth performance and a more stable OS. Also, you will get the Samsung S Cloud services, improved Camera functions, a brand new lockscreen with multiple new customization settings, Direct Call, Smart Stay, Pop-up Play, New widgets just like the ones in Galaxy S3, two homescreen modes, the Google Now service and a new notification bar that offers you more notification toggles.

Numerous other small improvements are implemented within Android 4.1.2, that you will find only testing the entire OS. This Jelly Bean update for Galaxy S2 I9100G has the JZO54K build with the XXLSR firmware. Note that by updating your device with the latest Jelly Bean ROM, then your battery life might suffer. That’s why you should create a backup of your current before installing it.

If your Galaxy S2 I9100G runs on a custom ROM, then you will not receive the official OTA notification, which is why you will be forced to use the Samsung KIES software in order to get the Android 4.1.2 Jelly Bean update.

The guys at Sammobile are the ones who spread the word out about the latest Jelly Bean update for the I9100G phone.

If you don’t want to use any other software to update and you didn’t receive the OTA alert, then you will need to get to our I9100G device section and look for the ‘how-to’ guide. It will teach you how to manually install the Android 4.1.2 stock XXLSR Jelly Bean firmware on your Galaxy S2 (you can find a direct link at the end of this post). IMPORTANT: If you’re installing the update over a rooted device, then the root will be revoked. That’s why you should return to our website, as we will post a brand new rooting guide for Android 4.1.2 JB on Galaxy S2 I9100G.

NOTE: Not all countries are getting the update today, which is why you can choose to wait until Samsung / Carrier pushes the update for your region. Also, if you found this post but your device is the Galaxy S2 model I9100 then you can find the Android 4.1.2 update guide HERE.

Update your smartphone, test all its new features and tell us in comments which are your favorite components in Android 4.1.2 JB or you can choose to post any bugs you might find in it.
