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.
