AT&T Samsung Galaxy S2 Skyrocket Receives Android 4.1.2 Jelly Bean Update

A couple of days ago we’ve told you that the Android 4.1.2 Jelly Bean update for Samsung Galaxy S2 is rolling out at T-Mobile and we knew that AT&T’s Skyrocket should be updated soon after. Well, as you’ve probably guessed, today we will be talking about updating the AT&T Samsung Galaxy S2 to Android 4.1.2 Jelly Bean, as the biggest carrier in the US has started the firmware update roll out.

The Samsung Galaxy S2 came pre-loaded with Android 2.3 Gingerbread and received the Android 4.0 last year, but the Ice Cream Sandwich update didn’t bring any major changes in terms of user interface. Things will be different after you update your Samsung Galaxy S2 Skyrocket to Android 4.1.2 Jelly Bean, as the firmware update rolled out by AT&T is bringing the Nature UX interface that debuted on the Samsung Galaxy S3.

Besides the Jelly Bean-specific goodies like Project Butter, expandable notifications, or the highly appreciated Google Now, the Android 4.1.2 update for Samsung Galaxy S2 Skyrocket will also bring other goodies like S Voice, S Planner, S Memo, and some of the Galaxy S3-specific features like Direct Call or Shake to Update. Since we are talking about a firmware update released by AT&T, the Android 4.1.2 Jelly Bean update for Samsung Galaxy S2 Skyrocket will also remove the Qik and MSpot and it will come with bug fixes, performance improvements, and better call quality.

The Android 4.1.2 Jelly Bean update for Samsung Galaxy S2 Skyrocket will bring the firmware version to I727UCMC1. It was reported that the firmware update come through Kies, but you might also want to check whether or it’s available OTA. To do so head to Settings > About Phone > Software Update and hit the Check for updates button.

Just in case you forgot, we remind you that the Samsung Galaxy S2 Skyrocket 4.5-inch Super AMOLED Plus display, while being powered by a dual-core 1.5 GHz Qualcomm MSM8260 Snapdragon CPU with Adreno 220 GPU. It also comes with 1 GB of RAM, 16 GB of internal storage and 8 megapixel camera with full HD video recording support.

Summing up, grab your USB cable, open up Kies and install the Android 4.1.2 Jelly Bean update on your Samsung Galaxy S2 Skyrocket. If for some reason you can’t update the device through Kies, you can take a look at our tutorial for manual update via Odin here.

    Thanks for new

    Any bugs to speak of?

      I received S Voice with the 4.0 (ICS) upgrade but lost it with the 4.1.2 upgrade. Now, the unit is sluggish and sometimes the camera doesn’t work.

    • La Loeder

      Mine is super slow, now that I have installed it. Can not use the filters on Instagram, since the picture space is blank and flickers the pictures every couple of seconds.

    Pisses me off how the S2 got 4.2.1, but tose of us with the GS3 are still waiting. Seriously, WTF AT&T??

    • AssainXx32

      I agree if anything the gs3 should have gotten the update first since its newer and more powerful it just makes no sense how an old phone can get the update before the new at&t quit fucking up!

  • NBP

    Install on galaxy s2 skyrocket went effortless and it took twenty minutes start to finish; as opposed to the ics update, which seemed to overwhelm servers involved. All new functions are very welcome and the phone is faster. Some things are different as far as interface but are definite improvements i.e. messaging,, contact lists, settings, arranging of widgets . this phone has been the best yet for me and now new os=new phone.

  • SoMo

    Mine is running sluggish. Seems to take longer for apps to start. Any fix?

  • La Loeder

    I have updated my S2 to Jelly Bean, but it has slowed down my phone so much! It was running way better on the former program. Some apps dont work well any more, like Instagram. Anyway I can go back to the old settings? How do you do that?
