A couple of months later than expected, Sony has now started pushing out the much-anticipated Android 4.4.2 KitKat over-the-air update to all unlocked variants of its flagship smartphone phablet of 2013, the Xperia Z Ultra, located in the United States. In addition to the latest build of the open-source operating system, this upgrade also brings improved battery efficiency and enhanced call quality.

Sprint has announced that the much-anticipated Android 4.4.2 KitKat over-the-air update is currently in preparation for its carrier-branded Samsung Galaxy Mega (5.8 and 6.3), Galaxy Note II, Galaxy S4 Mini, Galaxy S III, and Galaxy Tab 3 7.0 variants located in both North and South America.

Motorola has updated its official Touchless Control application on the Google Play Store for Droid Ultra, Droid Mini, Droid Maxx and Moto X owners running the latest build of Android 4.4 KitKat. This latest version of the app allows its operators to say a voice command and in return have their notifications read aloud to them without even having to come into physical contact with their phone.

Earlier today, Sprint posted a series of upgrade documents on its website for an over-the-air update that it’s already in the process of pushing out to all its carrier-branded Galaxy Tab 3’s currently located in the United States. Sadly, this upgrade doesn’t bring any major software modifications, such as Android 4.4.2, but it does bring the usual multitude of bug fixes and stability improvements.

Samsung is currently rolling out the much-anticipated Android 4.4.2 KitKat update to all International models of its former flagship smartphone, the Galaxy S4, located in parts of Asia and Europe including Poland, Malaysia and the Philippines. This rather hefty upgrade is a fairly major bump up from Android 4.3, bringing support for the Galaxy Gear, together with the usual multitude of bug fixes, stability improvements and speed optimizations.
