Official: Verizon HTC One Android 4.3 now available for download
After posting the official HTC One Android 4.3 changelog to its support site, Verizon has started pushing out the update to the phone. The update was originally promised for an October release, but carrier certification by Verizon seems to have taken a little longer than HTC had anticipated. Most of the tweaks are under the hood, but be sure to check out the full list of new features here. 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.
Now that Android 4.3 for the Verizon HTC One is out, work on HTC’s side should be shifting to the Android 4.4 KitKat release which is currently scheduled for the first quarter of 2014.
