T-Mobile HTC One Android 4.3 update now available - HTC Source
T-Mobile has certified the Android 4.3 update for the HTC One and is now rolling out the update to its customers. Like the AT&T and Sprint updates for the HTC One, the Android 4.3 was originally promised with an end of September release, but T-Mobile’s testing and certification process simply took took a little longer than HTC expected.
The T-Mobile HTC One is jumping from Android 4.1 to 4.3, delivering 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 all the under the hood functionality that Google built into its Android 4.2 and 4.3 updates. 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 T-Mobile HTC One.
