Samsung starts Android 4.1.2 Jelly Bean update for the Galaxy S II GT-I9100G

Samsung has just started to push Android 4.1.2 Jelly Bean update to the Galaxy S II (GT-I9100G). The Galaxy S II is the best-selling Android device of 2011 and has a very large user base that’s why Samsung keeps on updating this device with all the new Android versions as they want to provide the Galaxy S II users with their best support experience.

You might not be able to update your device to Android 4.1.2 Jelly Bean right away as the update is rolling out in phases. So, it might not yet be available for your country or network provider (If Your device is Carrier branded) but don’t worry the update will arrive soon.

In the history of software updates, the new Jelly Bean update by Samsung to the Galaxy S II is by far the most major update given to a smartphone yet. As we all know Samsung’s ICS update didn’t had any UI changes and had exactly the same UI which was in its Gingerbread but this is not the case with Samsung’s Android 4.1.2 Jelly Bean update. The new jelly bean update breathes a new life into the Galaxy S II, 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 S III Mini and the Galaxy S III, in its latest Jelly Bean update.

Some of the Enhancements in the new Jelly Bean Update:
- Buttery Smooth Performance & Great Stability (Thanks to Project Butter)
- Full User Interface Revamp (Same UI as of the Galaxy S III and Galaxy Note II)
- TouchWiz Nature UX
- Samsung’s S Cloud services
- Improved Camera features
- New Lockscreen With Many Customization Options
- New Features like Direct Call, Smart Stay and Pop-up Play
- New Widgets (From Galaxy S III)
- 2 Home screen modes
- New Notification bar With More Notification Toggles
- Google Now

You can update your Galaxy S II (GT-I9100G) through Samsung KIES or via OTA. Make sure you fully charge your device’s battery before upgrading as the update is quite big.

Official Firmware Details:
Android Version: 4.1.2 – Build JZO54K

All the new Android 4.1.2 Jelly Bean Firmwares for the Galaxy S II are present in our Firmware Section as well. You can use our Firmware Section to manually update your device if for some reason you can’t officially update your device via Samsung Kies or via OTA as you are using a Custom ROM or if your Country has yet not received the Android 4.1.2 Jelly Bean Update. Also, bookmark this page as we will keep this page up to date with the latest information on countries and network providers releasing the Android 4.1.2 Jelly Bean Update.

@ Pearl :- go to Accessiblity > Talk back > settings > Sound feedback

3 years 6 months ago

No this isn’t the option !
My intention is to turn OFF the vibration that comes when I press the 2 physical touch buttons (Back button).
The normal I9100 has an option called “vibration intensity” in Settings->Sounds which we also had in previous version ICS…. And this is missing in I9100G after the JB 4.1.2 udpate!!

Please do check and let me know !!

Can anyone help me out with something – I just upgraded my phone yesterday and I pretty much customized everything to my liking apart from Gallery. Albums used to be in alphabetical order and now they are not. I tried renaming, adding numbers at the beginning of the name, moving photos to my computer and back to phone, but no luck. It is a mess and since I have a lot of albums I can’t find quickly what I’m looking because they are in no particular order. Is there any way to sort my photo albums in built in Gallery app in alphabetical order?
