Apparently, the Android 4.4.3 KitKat update will be made available for the likes of the Nexus 4, Nexus 5, and Nexus 7 (2013), where all of them happen to be listed as including “security enhancements” and “various bug fixes”. Do not expect to see new features thrown into the mix, however, which would not come across as a surprise, either.
In the updates for the Nexus 4 and Nexus 7, those happen to be listed as build number KTU84L, whereas the Nexus 5 would carry the build number KTU84M. This update is touted to weigh in at approximately 54MB thereabouts, which is pretty much in line when it comes to an incremental update to a Nexus device. Well, it has also been rumored that Android 4.4.3 KitKat is said to have undergone internal testing for Samsung devices, not to mention a soak test invite that targeted T-Mobile Moto X users recently.
