After giving the Developer Edition of the HTC One Android 4.3 last week, HTC is now seeding Android 4.3 to the Canadian versions of the One. As you can see, it’s clearly a massive update at 572.22 MB.
The old version of Android was 4.1, so now you can get 4.2 and 4,3’s features of Bluetooth 4.0, Quick Toggles, and Lock Screen Widgets.
This update is currently hitting the Rogers and Telus variants of the One, but should be rolled out to the other carriers over the next few days and weeks. So go and check for your OTA update in the settings now, if you have a Rogers or Telus One.
Enjoy the latest version of Android. Hopefully this hits the US models soon as well, and the other international variants.
