The long-awaited Android 4.2.2 update for the HTC One has started its rollout on the Chinese dual-SIM version (M7C-DUC). It is rumored that the international versions — including those in the U.S. — could also receive this update sometime later on today day.

This update brings a shedload of much-needed changes to the device, including several optimizations and bug fixes. One of the biggest changes it brings is the new file format for Zoe, which makes for a much better file management tactic. And it goes without saying that this update also brings all of the usual Android 4.2.2 features, such as Google Now, Daydream, Gesture Typing, and expandable, actionable notifications.
