Has your device updated to Android 4.4.3 yet? Well, Android 4.4.4 is now rolling out. Google posted the factory images earlier today, and users of the Nexus 5 are starting to receive OTA updates as we speak.

What’s in the Android 4.4.4 update?

According to the changelogs floating about, the Android 4.4.4 update is mostly a security patch related to OpenSSL and a potential man-in-the-middle attack. The main bug appears to be the CVE-2014-0224, OpenSSL early CCS issue, which stems in part from the Heartbleed whopper we’ve all just gotten over. Here is a shortened sample of the changelog:

  • 6da2c75 : CTS test for OpenSSL’s early CCS issue (CVE-2014-0224)
  • e502d40 : Fix a concurrency bug in OpenSSLHeartbleedTest.
  • 1856a4e : CTS test for Heartbleed vulnerability in SSLSocket.
  • afae5d8 : Block access to java.lang.Object.getClass in injected Java objects

If you are interested in the nitty gritty of it all, check out the full changelog at the end of this post. So far, it looks like this update is not the next version of Android that we are all expecting to include a kill switch and run on ART instead of Dalvik. We also do not get a new name, the update still keeps KitKat in its title.

What devices will get this update?

Nexus 5 Android 4.4.4 infoFor now, Google has posted the factory images for the Nexus 4, Nexus 5, Nexus 7 (2012 and 2013 WiFi only) and the Nexus 10. Factory images require a bit of ADB know-how, good thing there is the Over The Air (OTA) updates for the rest of us. At this time, the OTA update is only pushing out to the Nexus 5 – if that is you, follow the normal update procedures and look for Build number KTU84P.

We have no confirmed word yet as to the updated Android 4.4.4 plans for GPE devices, or the normal carrier supported units that most users have in hand. Please check out your manufacturer or carrier website to see when they plan to update your device, if ever.

Back to that Nexus 5 OTA update. If you are familiar with ADB sideloading and don’t want to wait for the official OTA to hit your device, head on over to the Google Dev site to download the KTU84P image, you might then head over to this XDA article to get started pushing the update to your machine.

Are you receiving the update yet?

    Ok.. bring it on Google :)
    I know that most manufacturers will now skip 4.4.3/4.4.4 and directly jump board to the next major version of Android

    • Dude, nice name! You are probably right, but that is a dangerous game the manufacturers/carriers play, after all, Android 5.0 will be out soon (ish), then 5.1 and so on. Do you think avoiding the work to push out every iteration of Android is worth the security vulnerabilities for users?

      • suit up !

        The next version will obviously have all the changes till date
        But what security vulnerabilities ru speaking about
        I don’t see any worries other than personal data
        But that I thought was understood, when a person decides for an Apple

        • For sure, the next version will have previous patches, I consider any time spent unpatched to be somewhat of an issue though. So if a phone on 4.4.2 now has to wait for 5.0, that’s a lot of time out there with vulnerabilities. I do refer to user data vulnerabilities. I know we ‘freely’ hand our data over to Google and more, but that is a known entity, the idea of an anonymous hacker intercepting that data between me and Google is not cool.

    • Brendon Shipley

      Manufacturers will skip any heartbleed vulnerabilities? That word is such a buzzword now.

  • Ray

    4.4.4 was released to prepare your device for 4.5/5.0 or whatever the next version will be. Google has released a minor update immediately before a major update many times. Not surprised by this tbh.

  • OTA to the Nexus 10 is rolling too. Got mine a couple of hours ago.

  • Jakub Galuszka

    What about battery drains ,signal issues etc in 4.4.3.??

    • Jesus

      Haven’t had any of those issues with 4.4.3.

      But, the camera seems stuffed up – reboots phone sometimes.

    • Johan

      No issues here with all those. Working fine just like 4.4.2, signal is on the same level, no battery drains or whatsoever noticed on my phone. Just running as it should, only having the most recent app popping up for a second when using the back key to exit an application.

      • John Doe

        I am on 4.4.3 (Nexus 5) and have only seen an issue when using the app Zello.
        I exited the app and all is well again. You can see what is using the processor/memory/Battery in
        the system settings area under the appropriate heading.
        I have also switched to ART to test out certain apps, but not sure if this would have any effect on my battery or not..
        My phone with normal usage gets approx 2 days of use which is incredible compared to the Samsung phones I have
        had in my past!!
        Got’a say that this phone has been the best phone I have ever had … not only for battery usage, but also OS updates, speed and usage capabilities! It will be a Black Day in the industry, if Google never makes another phone!
        Yes, it might not have the best features compared with other phones, but then other phones lack the speed of getting their OS updates (if they even get updates …), and to me that is huge!
        I cannot wait to see what the Android team comes up with for the next iteration of the OS!!!

        Question: Will ART release Google from any patent issues that it has with MS or other companies?
        Was it created to eliminate patent issues, and make the system more Google centric or just
        to enhance/better the Dalvik run time process?

      I’ve had huge issues with battery drain since upgrading to 4.4.3 even after doing factory resets, clearing ALL caches and not running any third party apps. One Google Search will show you MANY people have the same issues. From what I can tell it seems to be Google system apps polling WiFi and data constantly.

    • Jakub Galuszka

      Yeah thats the problem ,there is many issues and everybody experience them…
      You dont have battery drain?Then you have GPS issues,you dont?Then buggy camera :(

      I hope they fix it.

  • Polys Antoniou

    And still no update for Nexus 7 (2013) LTE.

  • MasterMuffin

    It doesn’t have the kernel vulnerability fix that Towel root uses. Now it just warns that app is trying to bypass Android’ security protections. Hopefully 4.5/5.0 will have the fix

  • Jayfeather787

    Waiting for the custom ROMs to get 4.4.4.

    • Tommych

      They’re already out…

      • Jayfeather787


  • Mehul

  • Saad Khan
