The much-anticipated Android 4.2.2 Jelly Bean upgrade for the flagship HTC One has begun its rollout in Taiwan, just days after making its debut in China. The over-the-air release weighs in at 465MB and introduces a number of key new features.

Those include the ability to add widgets to the lock screen; a quick settings panel with toggles for things like brightness, Wi-Fi, Bluetooth, and airplane mode; a new Zoe file format; and home button enhancements that allow you to remove that annoying navigation bar that appears at the bottom of your apps.

Here’s the full list of changes:

System

• Android 4.2.2
• Launcher bar enhancement
• Widget panel rearrangement
• Lock screen widgets
• Enhanced Home button behavior
• Add Home button options to make navigation menu bar removable

Power

• Show battery level in status bar

Notifications

• Quick settings panel: 12 default settings by new touch gesture

Gallery/Camera

• AE/AF lock feature: Lock exposure/focus in viewfinder screen
• New Zoe file format for better file management
• Video Highlights: Add 6 more themes

HTC Sense Input

These things may change slightly based on your region, but you can be sure that core features will be available to all HTC One owners with this update.

It’s unclear when this update will be available outside of China and Taiwan, but we’re expecting HTC to roll it out around the world pretty quickly. As soon as it appears in other markets, we’ll be sure to let you know.
