As promised, AT&T is now in the process of pushing out the much-anticipated KitKat update to all its carrier-branded One Mini variants currently located in the United States. In terms of functionality, the upgrade will bring the latest build of Android 4.4.2 and Sense 5.5 to the handset, in addition to the usual deluge of bug fixes and stability improvements.

The One Mini is essentially a scaled-down version of HTC’s former flagship smartphone of 2013, the One, and packs a stunning 4.3-inch 720p HD display, a 1.4GHz dual-core Snapdragon 400 processor, 1GB of RAM, 16GB of internal storage (not expandable), an Adreno 305 GPU, a 4-megapixel “Ultrapixel” rear-facing camera and a measly 1,800 mAh non-removable battery.

Android 4.4.2 is an incredibly 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, autocomplete for the telephone dialer, Emoji integration for the stock keyboard, built-in word processing software and lots more.
