HTC has confirmed that it is working on updating its One series of smartphones to the latest version of Google’s mobile operating system, Android 4.1 Jelly Bean.

The confirmation came hot on the heels of a leaked document from the Australian wireless carrier Telstra that hinted that the Taiwanese manufacturer was working on a Jelly Bean update for the One XL, which is a 4G LTE-compatible variant of the One X.

Android 4.1 is easily the best version of Google’s operating system released so far, with a far smoother user interface and a slew of new features like the Google Now virtual assistant, updates to the phone’s search functionality and far better voice features, which include voice search and offline voice typing.

The HTC One X was the first flagship smartphone from a major manufacturer to be shipped this year, and it, alongside the One S and One XL, shipped with the then-newest version of Android, 4.0 Jelly Bean.

The One X features a 4.7-inch 720p display and a quad-core NVIDIA Tegra 3 chipset under the hood, while the One XL replaces this silicon with a dual-core Qualcomm Snapdragon S4 chipset that is compatible with 4G LTE networks.

While HTC has declined to give out a specific time table for the update, it confirmed that all the carrier-specific variants of the One X will get Jelly Bean update – including those offered by service providers in the United States. The promise for a Jelly Bean update could encourage additional sales for HTC, particularly considering that its primary Android rival, Samsung, hasn’t committed to pushing out an upgrade for its flagship, the Galaxy S3.
