HTC has announced that the US carrier versions of the One smartphone will be getting updated to Android 4.3 this month. The Sprint model started receiving its update yesterday, while the AT&T and T-Mobile versions will be seeing the update around the middle of October. Verizon's update is due to follow before the end of the month. HTC already pushed the update to developer and Canadian editions late last month. The company had expected to make the update available on US versions of the phone before the end of September, but it says it was held up by certification processes.

For the Sprint, AT&T, and T-Mobile versions of the One, the update brings the devices from Android 4.1 to 4.3, and includes lock screen widgets, numeric battery levels in the status bar, a quick settings panel in the notification bar, options to configure the home button, improvements to the camera, and a easier to manage file format for Zoe clips. Since the Verizon version launched with Android 4.2, it already had many of the user interface improvements that are coming to the other carrier versions.

HTC is the first manufacturer outside of Google to release Android 4.3 updates

Android 4.3 was announced by Google earlier this summer, along with the launch of the new Nexus 7 tablet. Google quickly released updates for its other Nexus devices, as well as for the Google Play editions of the HTC One and Samsung Galaxy S4. A number of manufacturers have committed to updating their existing devices with the new software, but HTC is the first one to make it available on carrier-locked phones. Google has already revealed the next version of Android, named 4.4 KitKat, is coming soon. Though the company has not detailed exactly what KitKat will offer, it is widely expected to be announced some time this month.
