An update is hitting AT&T's Galaxy S4 active today, but it's not KitKat. No, this update is finally bringing the more durable S4 variant up to Android 4.3 with the rest of Samsung's current generation.

unnamed 222

The update will come with version number I537UCUBML2 and the following changes:

  • Android 4.3 OS upgrade (http://www.android.com/versions/jelly-bean-4-3/)
  • Samsung Galaxy Gear compatibility
  • Drag and drop to uninstall or disable applications
  • AT&T Signature Experience preloads such as Kindle, Lookout, City ID, Password Keeper, Games and AT&T Mobile Protection.

The OTA should be available to manually pull down now from the system update menu. The download will be pretty heft at 772MB, so AT&T won't let you download it without WiFi.

    What a joke Samsung!!! Deciding to exclude fitness (ANT+) capabilities to your "ACTIVE" smartphones!!! ANT+ wireless capability connects S4 to fitness sensors like Heart Rate Monitors(HRM), foot-pods, etc.which was included in the standard S4 4.3 update. Bought this phone not to swim with it but rather to take it with me to hike, run, kayak, etc and have a built-in added water-resistance from an active outdoor lifestyle (sweat, rain, etc.) and sadly a clueless Samsung exec decides that their "Active customers" don't need fitness functionality that ANT+ provides. FAIL. Whoever made that absurd decision is totally clueless on customers that the "S4 Active" would attract.

    Has anyone actually been able to download this update yet? I've checked everyday since the announcment on my wife's S4 Active and I always get "Update interupted. Please try again in 24 hours." Found where I could download the .cfg file it pulls on XDA but her device isn't rooted so I can't move it to /data/fota manually. She won't let me root it :-/

    DO NOT DOWNLOAD 4.3!!!!! After download I cannot connect to wifi "your internet connection is unstable." Must charge my phone 3 times a day now compared to once a day before update, nothing else changed.
    Going back to iPhone as soon as I can!!!!

    Bullshit. As the Disappointed Runner said and still the 2 year old volume issue where you can't hear a fucking notification in your pocket. Then you go the shit hole called Google Play for a fix and that won't install. FO Samsung. Piece of shit. Unfortunately everything has stopped working and "OK" is all you can do about it. The battery cover is on correctly morons, and I'm on hold for support now over 11 minutes. Imagine that, thousands of calls about bullshit. 15 minutes now I'm hanging up.

    Here is a MAJOR impact of the update and it's NOT good. It totally will not charge if you use a NON Samsung battery or charger... Just will not work.
