Update: AT&T has published the changelog for the update (link to complete info):

The software update improves the AT&T branded application launch process, an EAS/Office 365 security pop-up fix,  and an update to all Google branded applications.

Hey, do you still have an original AT&T Galaxy S II? Really? You should probably work on an upgrade. However, on the off chance you haven't already custom-ROM'd the ever-living-Cyanogen out of it, Samsung's rolling out an update for it, as we've heard at XDA, and had confirmed by Samsung's own support website. Note that this is the original AT&T Galaxy S II (model i777) we're talking about - not the Skyrocket.

The ATT GS2 was upgraded to Ice Cream Sandwich back in June, and that was largely considered to be the end of the update line for Samsung's previous-generation flagship on Ma Bell. Turns out that's not the case.

A new update - obtainable only through Samsung's Kies software - is available. Update: Even though Samsung's FAQ insists it's Kies only, multiple users have reported receiving the update over-the-air.

The build number is LK3, and you'll need to be running build KK6, KH7, or LE5 in order to get it (all those builds start with the 'I177UC' prefix in the software version info in settings). There's no changelog at this point, other than upgrading to Android 4.0.4, but it's likely one will emerge sooner or later.


Samsung Support, XDA, Thanks Van!

      Whoops - and sorry for not giving you a shoutout! Let me rectify that.

        Thanks :D

  • David Z

    Gah is it that old? I have to wait till next winter to upgrade... AT&T didn't have any other great alternatives when I got mine (sure as hell wasn't getting the skyrocket). Anyway going to give CM10.1 for a spin tonight! Keep up the good work!

      It's been discontinued by ATT

    • Dima Aryeh

      If you haven't, try SHOstock 3. Pretty damn amazing ROM.

      • needa

        i was on shostock3. the theming was taken too far. it started looking pretty bad. great boot image though.

        • Dima Aryeh

          Oh, i see. Look out for some themes in the Themes and Apps section. Some people have released them already.

          • needa

            im on a n4 now. but thanx.

          • Dima Aryeh

            Lucky haha

          • needa

            i miss using my gs2 more than i like using the n4. gs2 is a monster at taking a slam to concrete. i find myself too scared to walk around with my n4 because of how clumsy i am.


          • Dima Aryeh

            It's indestructible. Excellent design

  • Dima Aryeh

    I believe the previous update was 4.0.4, was it not? This must be a bug fixer. Anyway the S II is an amazing device, still rocking one. Have a Note II in the mail but damn does this thing fly... ESPECIALLY with Samsung's TouchWizzed 4.1.2 ROMs.

  • Christopher Theofilaktos

    The S2 is a pretty good phone that a lot of people still use, so it's awesome that it's still getting support, definitely deserves it.

  • http://twitter.com/GitMuny Ciroc Obama

    Hey don't hate on the s2. It's an s3 with smaller screen really. Ok the camera is slightly worse and it isn't as fast or powerful but this thing still flies and hey, it's even getting updates. The S3 buttons are all wrong anyway...

    • Reginald Spence II

      Thank you. I can't stand that center cheap looking home button and that super glossy back. I'll gladly keep my S2 over that S3. Hopefully the S4 will be a whole lot better.

  • andrew__des_moines

    Time for an upgrade? Not with two year contracts. I love this phone, but I am more than ready to upgrade to the Note II.

    By the way, I just checked and it is available OTA (and downloading now for me).

    • http://www.androidpolice.com/ Artem Russakovskii

      Weird, the FAQ says Kies only. I'll update the article.

  • sylar

    The update is also over available over the air because as son as I connected to wifi it began prompting me to update.

    • http://www.androidpolice.com/ Artem Russakovskii

      Updated, thanks.

  • Eric John Nagel

    Just got the update, just before a thunderstorm moved in. Has just what screen shot above shows. All apps updated quickly, no problems so far.

  • Uncle_Rico

    It just downloaded via WIFI and is in the process of installing.. it looks to be about an 80MB download... I can attest that this is NOT a KIES ONLY update... yeah I was surprised this morning as I went to check my morning email and BAM!! the update notification was front and center... it just did it's first reboot after installation.... hmmm sitting at the "Rethink Possible" screen... hope it's not a "Rethink UPDATE!" scenario... my SG2 has been running smoothly on ICS so far... doesn't reboot randomly like it did on GB. NICE it's doing Application optimization... well.. there goes my APPS!! :/ DAMN.. hope my stuff still WORKS after this! more later.... it's coming back up now!

  • Uncle_Rico

    The "connect the dots" lock screen looks different... no more grren,, it's all the "holo" blue look. some of the icons have changed in the Notification Bar. It's in the process of "Installing Applications"... I don't remember this step from previous updates.. although it stated that it completed successfully... I have a feeling I'll experience a few issues with some appications.. only because this update seems to have it's hands ALL OVER the applications...?

  • http://twitter.com/MrZaius Sean Crago

    How sad is it that this news hits on the day CM10.1 nightlies are announced for it?

  • Uncle_Rico

    you know what all the Application activity is... ATT is REINSTALLING their baked-in Apps.. DAMN IT!!

  • Uncle_Rico

    nice! The messaging UI is cleaner... more ICS "holo" like.. and ATT DID "reissue" all 10 of their bloatware apps.. and are now crying for manual updates through Google Play! ugh...

  • Uncle_Rico

    According to my ChangeDroid App, there seems to be quite a number of core android services changes that came with this update... LOTS! hmm.. I'll have to play around with it more to see what these cahnges "look like" from the user pspective.. I've seen some minor UI changes so far.

  • spunker88

    A dual core phone with a GB of RAM and you think people should upgrade? All of us aren't made of money, theres a reason we picked Android and not the iPhone.

    • fixxmyhead

      yea seriously the s2 is still a good phone. im selling mine cuz the power button is messed up and i have my nexus 4 but yea i dont think people should upgrade. this phone can handle anything u throw at it. i swear david is dumb.

      • http://twitter.com/Imaginos88 Scotty Heinl

        Most people on the internet that write these reviews are dumb. :P

  • Jake Achee

    I came here to echo what everyone else is saying, The SGS2 is getting a bit 'long in the tooth' but the phone is still fully capable of running any app I throw at it. Sprint Galaxy S2 owners like myself can flash the official JB 4.1.2 leak and drastically improve the speed and usability. The phone feels a lot more like a GS3 now, including the quick-toggles and brightness slider in the pulldown. I would have upgraded if I wasn't on this lame 2-year contract but now I'm glad to get my money's worth and will be content until the GS4!

    • Dima Aryeh

      Same for the AT&T model, it has an Exynos and runs I9100 ROMs. We have the same 4.1.2 S3-esque ROMs :)

  • Noah

    Has anyone else noticed that after the update, the phone is very sluggish? Everything is running somewhat poorly right now, almost as if I am using my old Captivate

  • GoCrzy

    does anyone notice with this new upgrade your battery dies super fast and freezes?i have the galaxy s2

    • http://twitter.com/rdenton74 rdenton74

      Yes i have and my phone shut of for no reason

      • Luca

        Same here. Updated 5 days ago and had about 5 random shutdown. To restarted I had to long press the power button. Anybody can tell me how to go back to 4.0.3?

        • Rahul

          Same here 5 days..... 8 shutdowns and it doesn't even starts with power button you have to take out the battery and then restart.

          • Raffi

            Been having this same problem for months. Anybody get any solutions?

  • Kraut

    Just got that 4.0.4 on my '777', what an unexpected Christmas Present.

  • http://twitter.com/Imaginos88 Scotty Heinl

    S2 Kicks ass S3 Is Ugly Looking Upgrade ?? No Your a Dumb Arse

  • giomarco

    damn the update locked my phone. :|

  • s2tils4

    Battery life is majorly improved. Finally squashed that battery bug! Three more hours of battery life! Camera launch speed is fixed and app load speed is better, also ui speed is much better. No more auto restarts. Much happier now i don't have to rely on my spare battery so much.
