Android manufacturers are often slow adopters when it comes to updating respective smartphones to the newest operating system versions. However, it appears that the oft-repeated mode will not haunt smartphones this time as HTC is reportedly already working on the Android 4.1 Jelly Bean update for the mid-range HTC One S and the super-sized One XL.

Australian network carrier Telstra updated its Smartphone Software Updates page on Wednesday with HTC One XL and HTC One S listed on the top, along with Samsung Galaxy Nexus, to receive the latest iteration of Jelly Bean.

"HTC is preparing an update but is yet to confirm the date it will be submitted for Telstra testing," the carrier quotes on the update page.

There is no ETA date associate with the update. Nevertheless, the words are enough to confirm that HTC is on the track to update its One S and One XL with the latest Android operating system. However, do not expect the update to reach smartphones any time soon. HTC has just started prepping the update, which goes through many stages, where the manufacturer will integrate Sense UI skin on the top along with some additional apps and features.

The foremost feature of the Jelly Bean OS is a significant boost in responsiveness of user interface with what Google calls "Project Butter". The new innovative feature offers triple buffering in graphics pipeline to ensure that consistent frame rate is maintained during animations. Other features of Android 4.1 include Google Now (bumped- up version of Google Search), offline voice typing, update to Android Beam, and couple of tweaks to the homescreen and notification bar.

Reportedly, many smartphones on the Android 4.0 update list are still waiting for the OS to arrive. It is believed that the Android 4.1 Jelly Bean may not reach any non-Nexus smartphone this year. However, the speculations seem to be incorrect as HTC is prepping a Jelly Bean update for its One series of smartphones. This time the newest Android OS will reach smartphones in a lesser time than what Android 4.0 ICS update took.
