Following the release of full factory images for all supported Nexus devices, Google has begun pushing Android 4.4.3 to the Android Open Source Project (AOSP). The push is ongoing and should be complete within an hour or two.

The build numbers are KTU84M for the Nexus 5 and KTU84L for the rest of the Nexus devices. The AOSP branch is kitkat-mr2-release, with the tag most likely named android-4.4.3_r1 expected to arrive shortly.

Here are several links pointing to the newly released code to get you started:

Update #1: The tag, indeed named android-4.4.3_r1 (KTU84L), has just popped up as well:

Update #2: Another tag android-4.4.3_r1.1 (KTU84M) just appeared:

Of course, you might be wondering what the source code availability means to you. It means custom ROMs, such as CyanogenMod, AOKP, ParanoidAndroid, OmniROM, etc. can start merging the changes and attempting to build Android 4.4.3, maybe even as soon as tonight.

    It was about time. Now lets see how fast Motorola provides this update.

    • whispy_snippet

      I was starting to think Google was going to skip it and just move us all on to 4.5/5.0 at IO.

  • garychencool

    OMG OMG OMG OMG OMG *furiously spams the check update button*

  • Harvie Boles

    Running 4.4.3 already nothing unusual yet except for the color of the dialer I guess :D and "bug fixes"

    • Dominic Powell

      color of dialer?

      • Nathan

        White instead of black. Plus cards (Speed dial).

        Blue is slightly different. More colors for contacts. Uhm, maybe tapping the dial button has different effect I'm not sure.

      • Chazz Matthews

        KitKat was never meant to be colorless. Some devs thought less color than jellybean meant no color. That's bit what Google intended.

    • Sam Del Valle

      Thats something I was looking forward to!

    • Jdban

      I think it might've improved camera focus. But it could just be placebo.

      • h4m

        I was thinking the same. Could be improved, could be placebo^^;

      • Mad1723

        Part of the changelog was faster focus IIRC

  • Badouken

    Hopefully Paranoid Android's weekly update tonight slides 4.4.3 in there.

    • Frederico Silva

      It won't. "...we will never release anything without having time to test it and it is to close to release for any more merges "

      • Badouken

        I expected as much from PA, they love to be as stable as possible.

        • Evan Anderson

          Any ROM with a good release cycle and development practices would hold off on merging a new Android release if they have their own release slated for the same day.

  • tokuiten

    Please let this fix the data connection dropout bug, please let this fix the data connection dropout bug, please let this fix the data connection dropout bug...

    • Gsizzle

      For a second there I thought you mentioned 3 different things that were a 'must' fix.

      Then noticed you just repeated the same damn thing over n over again -_-'
      Thanks for making me use my brain.

    • Justin Swanson

      I don't remember seeing this is a bug, but since you've mentioned that it is. I hope they fix it also. I figured it was just my carrier being weird.

    • h4m

      When does this bug happen? How can I see it on a N5?

      • tokuiten

        If your data connection doesn't work half the time even though you've got full bars and it's showing white in quicksettings, your device is affected by it.

        It hit me only a few weeks after I got my N5.

        • h4m

          If it's not a hardware failure. That never happened on my N5. Maybe something with LTE or 5Ghz WiFi which I don't use.

          • Tomáš Petrík

            It's been happening to me in the past weeks on HSPA as well, so it's definitely not LTE-exclusive.

          • Andrew Beard

            From what I've seen it seems like an issue handing off between LTE and 4G towers Rarely happens near by office (which is blanketed with LTE), never happens at home (where I've got an AT&T microcell) but it happens all the time near home (where I go in and out of LTE pretty frequently). Maybe the LTE radio locks up, but the 4G data portion has already been shut off or something. I've definitely seen it on both T-Mobile and AT&T, though, so it doesn't seem to be carrier specific per se.

    • valapsp

      Fixxxxxxxxxxxxxxxx

      • Noob

        This happened to me too. What's weird is that it happened to me at exactly ' 12 minutes ago ' as well.

    • Bakaouji

      Well, did it?

  • Ryan Callihan

    Hoping that the T-Mobile Moto X soak tests are 4.4.3 as well...

    • usamaisawake

      That would be awesome! Of course last time AT&T was slow on the uptake so I'll know to be patient with my AT&T Moto X. Honestly though I was expecting Motorola to skip this and wait for the next big update to Android.

  • Defenestratus

    *Crosses fingers for NxP HCE support*

  • usamaisawake

    Love these factory images. All the Nexus devices in the family are now up to date. So easy to push and update that way. I only wish other Android devices were this easy.

    • http://about.me/jovanphilip Van

      They are. All the major manufacturers already do this. Of course, they aren't as timely as Google is.

      • usamaisawake

        It was my understand the unlocked nature of my Nexus bootloaders is what allows me to flash these factory images to the device? My AT&T Moto X does not have an unlocked bootloader so I didn't think this was possible on that phone?

        • http://about.me/jovanphilip Van

          Nah. The locked bootloaders stop you from flashing non-factory images. There are stock images for every version of the X.

          • usamaisawake

            Actually I think you cannot flash with a locked bootloader. https://motorola-global-portal.custhelp.com/app/standalone/bootloader/recovery-images -- the AT&T Moto X does not participate in the unlocking of bootloaders. And according to that website it seems Motorola does not support the flashing of stock images to devices that have locked bootloaders.

          • http://about.me/jovanphilip Van

            It may not be supported but it's possible. There are threads in the Moto X subforum on XDA explaining how to flash other carriers' ROMs for example.

            It's also possible with the international versions of the Galaxy S3 and Note 2 (which probably means it's possible with every other Sammy device).

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

            Sim unlock is not the same as bootloader unlock.

          • http://about.me/jovanphilip Van

            I'm confused. Where was sim unlock mentioned? o_O

            Also, wow, 5 months. Please tell me you aren't drunk replying to old comments lol.

    • Rod

      Without losing data?

      How is that done?

  • Noob

    Wondering why they didn't throw in the whole

    " Power by Android "
    thing to the boot animation.

    • Ali

      Probably because Nexus users know the difference between Android and Galaxy.

      • Richard

        Its not just android and galaxy because it's also on HTC m8 if I'm not mistaken.

        • J_Pod

          Also on it's on the HTC M7 after the Sense 6 update.

        • Noob

          Exactly what I was thinking. First phone I saw with it was the Moto X.

    • mgamerz

      Cause they wrote an article on it already about Google Play Certification?

      Edit: to the article or the update?

  • John Vines

    Nexus 7 2013 mobile seems to be MIA

  • Rod

    Camera focus and notification led fixes, please!

  • Matthew Fry

    What does the L vs M thing mean again?

  • rectangularcircle

    gotta say i am really let down by both google and the android community that frequent message boards. i feel i need to have a discussion on this matter

    let me explain.

    have been using android for years. came over from iphone and loved it. My first android was the htc sensation followed by the htc amaze, galaxy s3, note 2, nexus 5 and now moto x. the nexus 5 and moto x just happened within the last two months.

    here's why i am letdown,
    For years, or as long as i can remember most of the android community have had a very deep dislike of skins. (touchwiz, sense, blur etc) They have always claimed the superiority of stock android, for various reasons. no matter what website or blog i went to, if there was a mention of android skins there would be a ferver of posts proclaiming hate and inferiority of that said skin.
    so i got in the mood to get a new phone. I went and got a nexus 5. after about 10 days of disappointment in stock android i decided to get another phone. I heard great things about the moto x and heard that it was a slightly modified version of stock android. So I got it. Yet still i sat around for almost a month trying to figure out what the big deal is. As far as i can tell stock android just might be the most inferior OS on any smartphone.

    why do i say that? because in 2014 mobile OSes should be equipped with certain features as standard. the answer to everything should not be to "download a third party app" if i am having to download a 3rd party app than that means that functionality is not provided to me in my OS, or a better version awaits me from someone else.

    examples:
    -automatic rejection of a phone number. i have to create a contact? and save it?!? seriously??!?
    -notification quick toggles, no i should not have to swipe down and then press something just to get access to be able to turn off or turn on basic functions of a phone by holding it down. one swipe and tap is much more convenient and better.
    -volume controls are specific to the task that the phone is currently doing. being able to control the volume of the ringer, media, and notification is way more convenient and better than the stock android way.
    -notification badges are not present in stock. thats just stupid. my last flip phone had that!
    -sms....too much to say, in short, just about every alternative is better and more feature rich than the stock version

    the fractional speed difference in the stock vs skins is not enough to validate everything a person gives up by moving to stock

    i could go on and on, but i hope we can have a clear discussion about this instead of fanboism taking over. so help me out here, what am i missing about stock that everyone else sees? if i were to eliminate the generic answer of "you can download this app or this launcher" what argument could the stock enthusiast provide?

    • Ajanu

      By not downloading apps, or rooting, you are missing much of the point of stock android. There is no way Google can design an os that is perfect, but my Nexus 4 is. That is due to lots of playing to get it to do exactly what I want. If someone asked for a phone recommendation, I would not recommend a Nexus, for the reasons you listed.

      • rectangularcircle

        thanks for the reasonable response.

        but let me ask you, if your stance is that stock android's strength is being able to replace/improve the os, than arent you saying the same thing i am?

        customization and rooting exists for a lot of phones, thats not something exclusive to stock android. so i dont see how that is positive for stock android. and i will venture to say that when you do root and customize you are putting features and abilities on your nexus that skins already provide.

        • Ajanu

          Skins don't provide everything I want. I have never seen a skin give custom autobrighness, rearrangeable quick settings, nav bar height adjustment and key reassigning. No one else uses their phone like me, and so no one else would design a phone to work like mine does. I concede that I am making my own skin, stock android is just the best place to start since I can't code and create my own rom from AOSP.

          That said, Google is making big improvements and I expect once android silver is released it will have a much more polished stock experience.

          • rectangularcircle

            not sure by what you mean but
            -auto brightness and a brightness bar are available to you in touchwiz in the notification shade if you want it. (one swipe down) neither is available to me in the nexus 5
            -the quick toggles are also available for you to rearrange in touchwiz one swipe down(thats not possible on the nexus 5, since their are no quick toggles)
            -i dont see anything in the nexus to adjust key reassigning or nav bar height.

            but i think your missing the point of what i wrote and i definitely think your the one i was aiming at. i am aiming at the ones who claim stock is better always and forever and i am challenging that idea with the examples i gave, still waiting for some one to counter.

          • Ajanu

            I adjust the brightness that autobrighness reaches because I find it too bright most time. I get quick settings tiles as a single pull down from the right if the status bar, just like a toggle bar but not taking uo space in the main notification shade.

            You are missing the reason stock is great. It's because it comes relatively bloat free, and what is there is easily removed. Then you can make it what you want. You are looking for someone who likes stock with no modifications, and I don't know if that person exists.

          • rectangularcircle

            no i am not looking for "stock with no modifications" considering that is what you took away from my post i can already tell your comprehension is lacking and that this may very well be a waste to try and explain it to you.

            to all the stock is better than skin people out there, what do you base that comment on?
            - the lack of common features present on every other major platform including basic/flip phones?
            -the fractional speed difference that only gets noticed when doing side by side comparisons?
            -the ability to replace stock with something else?

            for all the praise stock gets, barely any of it is warranted. this post was directed at those guys to explain to me why the average person should be impressed with an inferior operating system that needs a third party app or launcher for just about anything.

          • braxton

            The POINT in stock is that is is barebones! That way we can customize to be exactly as we want it for ourselves with no bloatware, no outdated system services, no hardware-locked apps or permissions, etc.

            The very reason you crave touchwiz/sense/etc. is the very reason we hate it. That's why you can't understand.

    • mgamerz

      Swipe down with two fingers to get to quick settings a phone. I find it's great having all the extra notification space instead.

    • Zak Taccardi

      It's not a fractional speed difference. The Moto E loads certain apps faster than the GS5. The Nexus 5, with a worse processor, has a faster overall user expereience.

      It's also a very cohesive user experience - unlike Touchwiz, for example.

      The most important part - when a new version of Android drops around Google I/O - stock users get it right away (or within a month).

      Nexus/Stock devices can also be supported longer too

      • rectangularcircle

        i cant speak of the gs5's fractional speed difference. but i do have a note 2 and nexus 5. and when launching apps, or scrolling around the os (except the browser) the difference is only noticeable if you are doing side by side tests.

        do you mind me asking just how much of a difference you experienced? ( 2 seconds, 5 seconds, or less than 1 second)

    • twat

      you're a fucking idiot

      • rectangularcircle

        way to contribute.

    • gargamel

      You're funny, and I don't think you understand what is the meaning of an OS. The OS should provide core functionality, bare bones. You should then ADD functionality that you like. IF you are looking for a phone full of apps pre installed, get a dumb phone.
      To make it clearer- what happens if I want to remove one of the apps/functions that come with a Samsung phone? I cannot, can I? on a Nexus, you can add what you like, so more control for the user.

      I actually think that Google is putting too many apps on recent nexus phones. I should have the choice to install Keep, not have it pre installed. But that's another story, how AOSP is dying and Google Android is taking its place...

      • rectangularcircle

        i find that your remark of "i dont understand what the meaning of os is" is semantics. they are their to provide functionality. i agree, where we differ is what is definition of basic functionality.

        quick example:
        considering i have used all those different phones with different OSes. stock android was the first one that did not provide me with notification badges. at this point in 2014, after using all those phones and including my basic flip phone from almost 6 years ago. i consider the notification badge a basic functionality since every other phone had that ability. to try and say that not having it is equal to or better than having it is unreasonable.

        as far as your example goes of removing apps. that goes for every phone. i cannot uninstall the dialer app, chrome, hangouts, or email. so i end up having to do what i did on my other phones. either hide it or disable it. the same can be said for functions. i want to get rid of the scrolling wallpaper and have it with a stationary one. that isnt allowed in stock android either.

    • Bakaouji

      1) Mr Number from the play store
      2,3) Xposed + gravitybox after rooting your phone (rooting nexus 5 is very very easy and won't void your warranty)
      4) ????
      5) Plenty of great SMS alternatives on the play store.

      Or just install a custom rom. Nexus 5 has dozens of stable roms, something the other phones can't boast of.

      • rectangularcircle

        i appreciate the response but i already have downloaded apps that provide me the basic functionality available on everything else. that was the point of my post.

  • fjleon

    what is happening on every story? i can only see the subject, not the body of the articles, i tested every major browser.

    I can't read any articles of AP on my phone
    anyone else having the same problem!?

  • username_already_exists_error

    new kernel source isn't available yet

  • Fatal1ty_93_RUS

    So the AOSP is already ahead of factory image in terms of how new it is?

  • Amarus Kh

    Shame on you AP, it's unacceptable that you have still not reported whether "Performance Boosting Thing" made the cut in 4.4.3 or if it's being saved for the next major version.

    • Android Developer

      I'm sure they didn't notice it, as it will probably come in the next major release.

  • Android Developer

    I wonder which rom will be the first to use this version , that is not for Nexus line.

  • CyberPunk

    Shaded background on the multitasking screen is back in 4.4.3. I had a dislike for the all-black one in 4.4.2.
