Android 4.1.2 Jelly Bean Update For Samsung Galaxy S2 Released By T-Mobile

Samsung has been really busy lately, not only with the launch of the Galaxy S4 and other mid-range smartphones, but only with preparing the Android 4.1.2 Jelly Bean update for its older Galaxy S2. Such a software update takes time because the device has sold by many carriers, each of them offering a different version.

The good news is that Samsung is taking care of the problem and after readying updates for some of the Galaxy S2 variants such as the GT-I9100P, the Indian variant and the Three UK Galaxy S2, now its time for the T-Mobile model to receive the Android 4.1.2 Jelly Bean update.

T-Mobile’s version of Galaxy S2 has the model number SGH-T989 is it’s different from the standard model sporting a Qualcomm Snapdragon S3 dual-core processor clocked at 1.5 GHz. The smartphone also includes 1 GB of RAM, and a 4.52-inch Super AMOLED display with a pixel resolution of 800 x 480.

When the T-Mobile version of the Samsung Galaxy S2 was launched, it was running Android 2.3 Gingerbread. The device was updated in June 2012 to Android 4.0 Ice Cream sandwich. However, with the Android 4.1.2 Jelly Bean update, the users of the Galaxy S2 will get a new user interface, which can be found on the Galaxy Note 2 and the Galaxy S3, along with brand new features like Project Butter, Google Now, Pop-up Play, Smart Stay, Direct Call and improved notification system.

Of course, you are probably eager to download and install the Android 4.1.2 Jelly Bean update on your Samsung Galaxy S2, but you have to be a little patient as the software updates are usually pushed in phases, which means that if you will not receive the notification today, you will probably get it tomorrow or the day after.

The Android 4.1.2 Jelly Bean update is available though Samsung Kies, as well as over the air. Before beginning the download process make sure your smartphone is at least half charged. Also, you may want to find a good Wi-Fi connection for a smooth download. Let us know if any of you have received the update.

      • Bek Kurd

        download the latest KIES on your PC first. Then plug-in your phone and be patient. It takes a while… will be done automatically.

    • Tess

      Virgin sent upgrades last week for Galaxy S2. Heard Telstra wont yet because of issues. Back up first as many Samsung apps are deleted and data will be lost – Task being one for example. I upgraded without reading about it or backing up and regret it greatly.

  • Pravin

    SII Battery last 50% less after new update to 4.1.2. Also, the screen refresh is slow. I am waiting the fix or would have to roll back to ICS.

  • raiderlu

    Jellybean 4.1 drains too much battery. Has a couple bugs. 100% charged I unplug it and it drops down to around 95%. Cool update, but these issues need to be fixed. I thought this update is suppose to be the top of the line. Or maybe the galaxy s 2 can’t handle 4.1??? Can someone let Samsung know! Expert feed back Please!

  • kimmy

    I updated my Samsung s2 today and it restarted and got as far as the samsung screen and that’s it, I’ve tried restarting, taking the battery out ect but no luck 🙁 any idea on what this could be?

  • First OTA update crashed the phone repeatedly. I did a factory reset hoping it would go back to 2.3.4 since 4.0 had been buggy too. It reset to a fresh 4.1 but after 5 days it wouldn’t start at all. The update is a HUGE space hog. Between all the new Google and Samsung apps more than 75% of the onboard storage was already used. The TouchWiz Home app crashes routinely. If this reset/reload doesn’t last I’m going back to 2.3.4 There’s nothing that cool that I can’t live without.

    • mohsin

      How we can go back to older version?
      Immediate suggestions needed…Phone is very slow with very low battery life…wana go back to 2.3

  • ParisAlishia

    I’m on tescos and still haven’t received an update yet 🙁 will I ever?

  • Jeff McCully

    4.1.2 on s2 has significantly ruined the swipe functionality. I spend more time correcting words now and typing instead of swiping. Seems that it’s library is different and alternative words are not even close. How can I get the old version back?

  • Pratima

    Got the firm ware upgrade, it took close about 2 hours though i was connected over wifi. But facing issues after that on my galaxy s2. Phone has become slow and switches off more often. Now I regret doing an upgrade.

  • Jane Williams

    Got it. It’s lost half my apps, and my wallpaper is no longer the nice custom one I’d downloaded (can’t find the file to put it back), but a different one I was using as the wallpaper on my desktop PC – or rather, a detail from the centre of that wallpaper (can’t find that file to adjust it, either).

  • Bek Kurd

    i installed the 4.1.2 on my S2 via Kies. I don’t see Project Butter, Pop-up Play, Smart Stay…

  • Shon

    it says my tmobile galaxy s2 doesn’t support initilising everytime i connect it to kies to try and update it. ive been trying everyday since it came out and it still wont update.
