HTC is among the first to confirm existing Android handsets that will be updated to the newest version of the mobile OS.
The manufacturer has said that its One X, One S, and One XL phones will all be upgraded to Android version 4.1, also known as Jelly Bean.
The upgrade will come to both the T-Mobile and AT&T versions of the phone, as well as overseas carrier Rogers.
The company didn't confirm any sort of time frame for when it expects the update to go live, but it should be one of the first to offer an over-the-air Jelly Bean rollout.
The Jelly Bean upgrade could be considered a minor update for the Android platform, which is why it only brings the version number up to 4.1 instead of 5.0.
The most functional aspect of the update is that it looks different depending on the kind of device, so 7-inch tablets have a different presentation of Jelly Bean than 10-inch tablets or smartphones.
Among the updates are increased enhancements to the speed and performance of Android, new and sleeker widgets for the home screen, expandable notifications, and a more user-friendly app for viewing and deleting photos.
It also offers a new touchscreen keyboard for even more seamless text input, as well as new features for the ever-growing list of near field communication (NFC) devices, allowing users to tap phones together to enable things like photo sharing.
