Not long after Google released images of the Android 4.4.3 KitKat update for its Nexus devices, the company has started to roll out the mobile operating system update to its Nexus lineup, including the popular Nexus 7 tablet as well as the Nexus 5 smartphone. Google Play Edition devices are also expected to receive the update soon. 

The update consists of mostly minor tweaks and bug fixes, among which is the newly redesigned Dialer app that was originally used simply to access contacts and make phone calls. With the 4.4.3 update, the application now offers more flexibility and features like allowing direct access to all information as well as marking favorite contacts. Another major fix that comes with the update is a solution to the crashing issue brought about by the 'mm-qcamera-daemon' process. Users of the Nexus 5 smartphone noted another issue -- that the battery life of their device experienced a quicker battery drain. Google has said that this was due to the process's high CPU usage. According to NDTV Gadgets's website, other devices powered by Qualcomm and Android 4.4 KitKat also experience the same problem. Other issues include phone call audio quality and GPS navigation. However, it is not apparent if the latest update will be able to fix these problems. 

Other flagship and popular smartphones will not be receiving 4.4.3 KitKat until their respective manufactures adjust and make the update compatible with their gadgets. The process could take anywhere from several weeks to even months. Samsung has reportedly been testing the latest version on its flagship smartphones including the Galaxy S5 and Galaxy S4 variants, according to an official document that has been recently leaked. While other manufacturers are in the testing stages, Google, in a developer's conference to be held this month, is expected to announce bigger updates -- possibly Android 4.5 or 5.0.
