(Updated With More Bug Fixes) Galaxy S II Software Update Begins Today, Wi-Fi Calling Included

I know Galaxy S II users were a little jealous by Mondays news of the HTC Amaze 4G software update that included Wi-Fi calling. Well be jealous no more Galaxy S II owners as your very own update is on the way beginning today giving you the very same Wi-Fi calling option.

Galaxy S II devices will be upgraded to Android 2.3.5, software version T989VUVKL1 that includes the following enhancements:

  • Caller ID enhancements
  • Battery enhancements
  • Wi-Fi calling enhancements

The upgrade will be sent Over-The-Air (FOTA) and will also be available via Kies Mini. This is great news for both HTC Amaze 4G and Galaxy S II owners as they finally have the awesome option for Wi-Fi calling.

    updated my phone …. tried rooting it and failed …. tried several times and it failed everytime :(

      You were already rooted?  I flashed the .tar but did not install the superuser.zip because I the app was still there but it turned out I still had to install the .zip in recovery mode and it worked.  Each time I rooted though, the .zip did not take on the first attempt but does on the second. 

      Dunno if that helps any.

    • IDONTPAY4WIFITETHER!

  • Androidman

    I cannot download Grand theft auto 3 on my galaxy s2!!! It says that it is incompatible.

    • anfrey

      looks like the sgs2 isn’t on the game’s device list (according to market description)

    • tmoRSL

      i got it , 

  • LuvFerrari

    u need to use the full version of kies for the S2 firmware update — kies mini won’t do it.

    after the update to 2.3.6 the phone does run smoother overall and the battery life improved about 10-15%.  other than the other improvements noted by others here, i found that the music player got a new icon n its UI also improved.

    my sim card (build 50-01) won’t work with the wi-fi calling anymore.  i was hoping to save the new sim which came with the S2 (build 50-05) for the future but guess i have to swap it out…  :-(

    overall the update was a needed improvement over the old 2.3.5.

    • anfrey

      my touchwiz music player looks the same as before, though it seems google music got reinstalled upon update.

      • LuvFerrari

        correct.  google music player was “re-installed” n updated.  however, the upgrade also affected the samsung music player thou — my settings in samsung music player were  reset to the default (my custom eq setting was gone, etc.)

        wi-fi calling is very convenient due to its “free minutes” feature.  unlimited calling while on wi-fi, in addition to continuous phone connection in non to low cell signal areas, was SWEET!

        • anfrey

          i was under the impression that wi-fi calling still used your minutes bucket… are you sure wi-fi calling minutes are gratis?

        • LuvFerrari

          i called tmo multiple times to get confirmation.  wi-fi calling is all FREEEEE, brother!  ;-)

    I had a worse case with my SGS update major fail. Using kies I downloaded the zip started to update and error came up. The SGS2 then went into this screen that said to do kies emergency recover. The cell stopped connecting correctly to my computer at this point. So, I can recover because its not being read by the computer correctly. The phone is in this limbo state where its not connecting to kies. Had now way of resetting. Vol up and down with power bottom didn’t do anything but give me the same screen (omni odmi mode, or something like that). Tried for about two hours to get it to sync and no go.  This was 12/16/11 night time.

    Next is not really about the update but does have a good ending. Next morning took it to tmobile store west covina on amar ave and I told the clerk/dude my phone locked up with this update. He said what update there is none for this SGS2. I told him the update for the wifi calling. He said the phone already has wifi calling. I told him well there’s a update. He said update from who? I told him from Samsung website using their sync software. The clerk said oh yeah you shouldn’t use stuff unless it comes from tmobile. That when I thought what a jackass who doesn’t even know there’s a update on what I assume their #1 phone and who thinks I shouldn’t update from the manufactures website. So the clerk takes the phone tries a reset and same omni emergency screen. He said you need to call customer service, last thing any one wants to here there just as bad sometimes as this clerk. I said who’s customers, He said what do you mean? I said Samsung’s or TMo? I thought it was his job to do this for me guess not. I know there was another person in the store being only helped by one other clerk so my clerk must have been in a hurry to help him so one would be there as there accustomed in Tmo stores. By this time I’m wasting my breath. Things are looking pretty down I’ve had the phone for less then a month and its junk now. On to plan B and Yess! I had it less than 30 days took it to Target in city of industry where I bought the thing. The cell phone guy was on it. Knew kies was Samsung software and I had my receipt so I want to see about a exchange. I get an exchange with what! 70 bucks back refund because the SGS2 is on sale for 129 today. Not only does he get me a exchange but gives me money back. The agitation I went though was more like 100 bucks worth but I’m happy camper with 70. Tmobile costumer service is a gamble sometimes you get people that are totally awful with no effort like the clerk at asuza and amar in west covina, ca on 12/17/11. Other times you get someone who knows there stuff and will do whats right.New phone over the air update today its…  good! 

    • anfrey

      did you catch the oblivious and unhelpful clerk’s name? perhaps worth writing a letter to tmo about?

  • Cwsl85

    I cant seem to get kies to connect to my phone. Is any one else having this problem?

  • Umiami47

    I bought my SGS2 on Thursday without the update and I can make WIFI Calling!

  • Sirivn
