has begun rolling out the Android 4.4 KitKat
software for owners of the HTC One Unlocked and HTC One Developer Edition handsets over the holiday weekend, and in the process has started to make good on a previous promise to equip every HTC One device
in the U.S. with Google's latest and greatest version of Android by the end of January 2014.
Neither of the above mentioned smartphones are tethered to a specific wireless carrier, therefore they didn't need to go through a lengthy carrier certification process. However, that isn't true of the remaining HTC One devices in the U.S., which are offered by all four major wireless carriers (AT&T, Verizon, Sprint, and T-Mobile).
Coinciding with HTC's roll out, Google announced on its Google+ page for Android that Samsung Galaxy S4 owners have also started receiving the update as well. Regardless of the device you're rocking, KitKt introduces a number of core and supplementary features, such as the ability to use your voice to do certain tasks ("Ok Google"), faster multitasking, prioritized contacts, a smarter caller ID, and many more.
