Samsung has been gradually rolling out the KitKat software update for international models of the Galaxy S4 and Galaxy Note 3 over the last couple of weeks. But surprisingly, it looks like at least one American carrier is eager to get Android 4.4 on the latest Samsung flagships as well. Noted XDA Developers forum member Designgears has posted official leaked builds of KitKat for AT&T's variants of the Galaxy S4 and Galaxy Note 3 - you can download and flash them right now.

These KitKat builds probably aren't the final versions that will eventually be sent out as an over-the-air update. The S4 build in particular (I337UCUFMLD) has a reboot issue when using video codecs. But those who don't mind taking a few risks (including flashing a new bootloader and losing any root privileges they might have) can load up the ZIP files and flash them via Samsung's Odin desktop tool. Designgears takes care to note that if you're unfamiliar with that sort of thing, it's best to wait for the official release. Apps and related data will probably be wiped out.

Both the AT&T Galaxy S4 build and the Note 3 build (N900AUCECMLG) weight in at a gigantic 1.5GB, which is consistent with official system image sizes. The build ID shows them as KOT49H, a.k.a. Android 4.4.2, which matches the international releases. We've got no idea how long AT&T will take to actually send out these updates, so if you're impatient, feel free to give them a try.

    I'd rather just wait. I used to own a Galaxy Nexus on VZW and just gave up with them. I flashed CM to that thing and I was happy. Once I got my GS4 on ATT, I really wasn't feeling the need to put CM on it. I think that once phones were on Android 4.1 or up, there isn't a glaring need to jump to the next version so quickly. Once you have Google Now most of the main features aren't that different, especially if Google keeps separating their apps and putting them in the play store.

    But we'll see with all of that if Google ever pushes out Android 5.0

    Been running it on my note 3 for a few days. Runs pretty nice so far.

    I don't see any comment in this article about the way AT&T's last big flash locked down the bootloader in July and made reflashing to custom ROMs on the Galaxy S4 a risk too large bare. I fully intended to get CM or the Google Play ROM going when I bought this phone. Then AT&T was pleased to cripple a feature that Android users expect from most devices; the ability to mod. So I'm stuck with Touchwiz and a dumptruck full of Samsung bloatware. No clue yet about what the new update will be good for, but until AT&T stops limiting its users, it is not exciting news.

      Download Nova launcher. It's way better than touchwiz and it has the kitkat settings. I'm so pleased and happy with Nova. It let's you customize your phone completely free and no risk

    Darn you Verizon, get a move on with that Moto X 4.4.2 update! Don't let AT&T and Samsung pass you!

  • dontsh00tmesanta

    If only CM11 had wifi calling I would be on it but since it doesnt it looks like I will have to wait for official tw 4.4

    "Samsung has been gradually rolling out the KitKat software update for international models of the Galaxy S4 and Galaxy Note 3 over the last couple of weeks."

    There's no offical 4.4.2 builds for SGS4 as of yet, only a couple of leaks.

    The biggest new features is the transparent notification bar and bottom launcher. I don't know about you but my Sprint version is already transparent, so if this update doesn't fix a few bugs, the update will be worthless.

    Can you guys confirm what we found - no Tap & Pay and no Wallet support in this KitKat build on the Note3?

    • Pleahy

      Tap and pay we the major reason I was waiting for Kitkat.. this would suck if Wallet was crippled

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

        Same here.

          FWIW, NFC is still broken in CM11 on the Note3 too :) , and was one of the big features in KK I was looking forward to. (The Wallet app doesn't seem to know that NFC is broken, though, and offers Tap2Pay up for use)

            T-Mob, but the NFC chip is similar. afaik, the international version uses and older nfc chip that's easier to support.

    Really wish I'd looked more at development before I got the AT&T Note 3. Locked bootloader, no CyanogenMod/AOKP/Slim etc. Just terrible.

    Hopefully someone comes up with a root method for this leak soon.

    I recently purchased a Note 3 via e-bay (overseas) unlocked for gsm and have been trying to decide on a Sim card from Walmart's discount service - AT&T or T-Mobile. In the meantime, I have been using my WiFi connection and downloading apps, etc., as well as stuff from my Nexus 7 (2012). Yesterday, the phone downloaded 4.3 and than 4.4 Kitkat. So Samsung is already putting Kitkat out in the US. Just thought I would let you know!

  • Zach Miller

    Heres the official install video guys!! Hope you like it!!
