Google has just started rolling out the Android 4.4.3 update for the Nexus 5 and its other Nexus branded siblings. While the company has already uploaded the factory images and binaries on its website, the OTA update is yet to go live.
The Android 4.4.3 update does not really bring with it any major new features or improvements, except for an improved Dialer and People’s app, and is mainly focused on squashing some internal bugs and improving the overall security level of the OS.
