Earlier today, Motorola posted the official update documents for an upcoming OTA upgrade for Sprint’s carrier-branded variant of its flagship smartphone of 2013, the Moto X. The paperwork reveals that the handset is set to receive the much-anticipated Android 4.4 KitKat update, in addition to a multitude of bug fixes, stability improvements and speed optimizations.

In terms of performance, the Moto X is a relatively impressive high-end smartphone, packing a gorgeous 4.7-inch AMOLED display with a resolution of 720 x 1280, a beefy 1.7GHz dual-core Snapdragon processor, an Adreno 320 GPU, 2GB of RAM, 16GB/32Gb of internal storage, a 10-megapixel rear-facing camera and a 2,200 mAh battery.

Android 4.4.2 is a major upgrade from 4.3, packing a completely redesigned user interface, SMS message integration in the standard Hangouts application, Google Now on the home screen, Wi-Fi printing capabilities for HP ePrinters and Google Print customers, autocomplete for the traditional telephone dialer, Emoji integration for Google Keybaord, built-in word processing software and lots, lots more.

Sadly, neither Motorola or Sprint have announced a date for the rollout of this upgrade, but we can assume that it is pretty imminent, though, seeing as manufacturers usually post these documents on their websites just a day or two before carriers start pushing out the update.
