Vodafone Australia noted the upcoming Android 4.4 KitKat for Galaxy Note 2 but still awaiting for software testing with estimated time of arrival this month. It is the same status for the Galaxy S3 LTE I9305T in the country except there is no estimated time of arrival and awaits official confirmation from Samsung.

Optus Australia goes the same with Android 4.4 KitKat for Galaxy Note 2 N7105 and will commence testing phase as soon as Samsung makes it available. According to the Web site, Android KitKat update for Galaxy Note 2 from Optus is expected to be released publicly from mid to late July of 2014.

Telstra Australia Android 4.4 KitKat update for Galaxy Note 2 4G has been delayed and based on their site, "Samsung have further delayed test submission to a date TBC" and classified the firmware under "scheduling." Galaxy S3 4G and 3G models are not included on the list of devices expecting to get an update.

Eligibility Status

By default, Samsung Galaxy S3 GT-I9305 4G and Galaxy Note 2 are eligible to Android 4.4 KitKat. Both were released at the same time around September in 2012 with first anniversary celebrated in 2013. If following the conditions of 18-month software support, April 2014 should be the expiration date.

It is up to Samsung to push further updates such as Android 4.4.3 and 4.4.4 KitKat versions on both devices which can be very useful due to reported bugs found on the Android 4.4.2 KitKat. However, users must wait till the network carriers finish the testing phase which can only be confirmed by Samsung.

Android 4.4.4 KitKat Changes

Android 4.4.4 KitKat has one major role and it is related to the OpenSSL. According to Android Police, the update was released to fix the OpenSSL bug that allows a "man-in-the-middle" attack which can be linked to the distinct Heartbleed bug on Android 4.4.3 KitKat version.

Aside from that, Samsung will add several changes as well to improve performance, increase battery life and optimize system apps just like any other firmware updates. At this time, there are no official details if Samsung will feature unique services such as a new TouchWiz or exclusive apps from Galaxy S5 on Android 4.4.4 KitKat update.
