Android 4.4 KitKat, unveiled on Halloween Day 2013, saw the arrival of some pretty amazing features to Android OS as we know it. Some of the newest features that made waves with vanilla Android users concern OS printing capabilities and a data monitoring feature, not to mention camera filters and the “easter egg” feature placed within KitKat itself. Android 4.4 KitKat was, indeed, the “sweetest” update to come along for Android users, but the dessert line doesn’t stop there.

Nearly three weeks ago, tech leaker and Twitter user @LlabTooFeR posted an Android 4.4.3 announcement on the wall, with the message “Android 4.4.3 is under testing. Build number is KTU72B. Probably it will fix known camera bug.” The same information was conveyed in a log file, showing a Nexus 5 running Android 4.4.3 KitKat. No information was provided at the time, except the announcement that there was an Android 4.4.3 KitKat build in testing.


With new information surfacing in the weeks since the new KitKat sighting, we can now confirm by way of even more details that Android 4.4.3 KitKat does exist and is headed to Nexus users in a few weeks. With that said, however, we want to take time to cover a few things that Android users can expect to endure before Google’s latest KitKat treat arrives.

Nexus Users Top Priority in Android 4.4.3 KitKat

This is not a surprise, but Nexus users will be the first in line to receive Google’s latest Android 4.4.3 build. As LlabTooFeR said in his Twitter post, the Android 4.4.3 KitKat update will likely fix the mm-qcamera-daemon bug that has been present within the Nexus 5 camera experience. The mm-qcamera-daemon bug is known for draining battery life significantly, with some users reporting in recent days that a their 12-15-hour battery life reduced at a quicker rate than earlier days with the device. Camera bugs are common with the release of new updates, but Google’s latest Nexus 5 bug does complicate things, especially when you consider that Google released its TRIM process into the Android experience last summer to extend the battery life of its Nexus devices.

As for the breakdown of the release of Android 4.4.3 KitKat, Nexus users will receive it first, likely in the order of new to old. This means that Nexus 5 users and 2013 Nexus 7 tablet users will receive the update first, followed by Nexus 4 and 2012 Nexus 7 users a few days later. Hopefully, the Android 4.4.3 KitKat update will improve my 2012 Nexus 7’s crashed camera.

What Will Android 4.4.3 KitKat Bring?

The one thing we know right now is that Android 4.4.3 KitKat will remove the Nexus 5 camera bug that is responsible for battery life drain and camera crashes. There have been other reports of additional bug fixes to come alongside of the camera bug fix, such as the following:

  • LED bug fix (missed calls)
  • Additional camera fixes
  • Wi-Fi auto connect
  • Phone call clarity
  • USB debugging
  • Bluetooth
  • App shortcut issues
  • Activation screen fixes
  • Subtitle improvements
  • Calendar, phone dialer, email, MMS, and VPN improvements
  • Random reboot bug fix
  • Power Manager display fix
  • Data connection drop

Alongside of these fixes, Google also looks to improve the camera experience with regard to camera focus. When the Nexus 5 was first released with Android 4.4 KitKat, the Nexus 5 camera had poor focus and was often responsible for blurry photos – even with the use of optical image stabilization (OIS) and video image stabilization (VIS). While the Android 4.4.2 KitKat update seemed to address the focus quality to some extent, there still remains room for improvement. While there are camera fixes embedded within the Android 4.4.3 KitKat update that we know little about, I sure hope there is a fix for the bluish tint on Nexus 5 photos that collides with accurate color representation.


Android 4.4.3 is currently in its “dogfooding” stage, meaning that the update has made its way outside of Google’s halls and into the hands of some OS testers. At this stage, it seems as if the update will soon make its way onto Nexus devices.

As the OS update number suggests, Android 4.4.3 KitKat will only prove slightly better than Android 4.4.2 KitKat. At the same time, Android 4.4.3 may prove to be significantly better for Nexus 5 camera users who are looking for a rescue from the current Nexus 5 camera.

  1. Yes android update 4.4.3 will also fix the leak found in SSL certificates which are used on two-third of all the websites online. With the new android 4.4.3 update heartbleed will be none of your concern anymore. Keep on pressing “check now” at system updates on your nexus device to be sure you’re the first who receives the update.

  2. We would also like if you’d add a sound profile widget which would make changing sound profile easy for us by just bringing the widget to the screen..And also display the battery percentage option

  3. Will this update resolve the major problem of not being able to receive phone calls or text while in 4g LTE! Or are we have to purchase a new phone. From another company like HTC.

  4. Not sure if others have faced this on their nexus 5 but my phone decides to make some calls to my contacts on its own. Then there’s the radio screech background to the calls. The worst thing thats happened, my phone just went into ‘coma’ on 2 occasions. Only the phone would ring and nothing else happens, the screen wont come up, u cnt switch it off.. Then after hours like a miracle saves the day the phone starts working again.. If anybody could discuss this or maybe provide more insight?

  5. Hangouts is also buggy with outgoing messages dissapearing into thin air after sending to certian contacts. Android Keyboard has also been failing on a weekly basis.

  6. To siba, some app permissions ask to make calls on your behalf without telling you. Try installing dcentral1 app from Google play.

  7. The ringing sound was so less
    Camera will not work at some moments
    WiFi direct problem
    Wifi problem
    Other mobiles are better compare to nexus 5
    At least for this moment and for new update 4.4.3 is going solve all these issues are not?

  8. Any possibility of LTE finally being activated on the Nexus 4? I could install the radio fix but there us no option to turn it on and off in settings.

  9. SIBA, I know what you’re talking about! I had the same thing happen to me. the phone would just stop working. i was using the phone and a call comes. all of a sudden the phone blanks out and goes to black screen and does not respond to any of my commands. i cant silence my phone and neither can I answer the call… The phone just keeps ringing and ringing.. i had to wait until the phone stopped ringing. I don’t know what the issue was but it just happened a couple of times.

  10. @Bull Durham dial *#*#4636#*#* to access the secret menu to enable 4g if you have flashed the correct radio.

    Also hangouts is extremely laggy.

    How many of you made your way here from the Google now page?

  11. I think google has to target the screen flickering issue or the bug bar at the toggle on screen button area. it is creating a pixel bar across the bottom of the screen . after 1-2 days use out from the box. Due to my device is brought into singapore I have to pay a couple of hundred dollars to send it back to google to fix my brand new phone. making me piss off.

    • hello tan key zin.. i have exactly the same issue, i was wondering if you already got the OTA and if that issue went away with it? or maybe did you solved it without getting a replacement? im in another country also and i have to send it back to USA…thank you
