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.

HTC One max owners on Sprint will wake up to an Android 4.4.2 KitKat update today. It weighs in at 344MB, and it brings everything you’d expect from a KitKat upgrade — including Google Cloud Print and security enhancements.

HTC’s Executive Director of Product Management took to Twitter earlier today to announce that the AT&T-branded variant of the One Mini, is expected to receive the much-anticipated KitKat update by the end of this week. The upgrade will bring the latest build of Android 4.4.2 and Sense 5.5 to the handset, in addition to the usual multitude of bug fixes and stability improvements.

Earlier today, Fitbit expanded capability for its wearable fitness tracker, the flex, to a further 44 Android devices. In addition to the Sync expansion, the American company also revealed that its recently revamped application will come preloaded on the brand new HTC One M8, which should, in turn, expose more people to its products, leading to an increase in sales.

According to a leak courtesy of French carrier SFR, the LG Optimus G will get the Android 4.4.2 update this Summer. So it seems like users of LG’s 2012 flagship still have a few months of waiting to do for the latest version of Android.
