Official: AT&T HTC One Android 4.3 now available for download
AT&T is now the second US service provider to roll out the Android 4.3 update for the HTC One. Jason Mackenzie announced on Twitter about an hour ago that the update can now be downloaded by AT&T HTC One owners. The update was originally promised with an end of September release, but carrier certification by AT&T took a little longer than HTC had anticipated.
The AT&T HTC One is jumping from Android 4.1 to 4.3. User should expect to see launcher bar enhancements, a widget lock screen style, home button behavior modification (remove black menu bar from screen), advanced notifications, ability to display battery level percentage in the notification bar, quick settings, 6 new Video Highlights themes with custom music options, improved Zoe file management and more. The update is being pushed out right now, but if you have not yet received the notification of your device, we recommend checking manually by going to Settings > About > Software updates > Check now on your HTC One.
