HTC are on the ball with dishing out the Android 4.4 KitKat firmware to all HTC One users as the Developer Edition and Unlocked variants of the device join the Google Edition smartphones and begin to get the new firmware via OTA upgrade. This time the firmware will include the Sense 5.5 UI and custom HTC tweaks. Carrier specific devices will be the last of the HTC One variants to receive the update and timing on that will be down to how quick the carriers can do their things. None the less, it’s nice to see how good HTC are keeping their word and are pushing the new firmware for all HTC One users to enjoy. If only other manufacturers would do the same.
