The update is now being released over the air and can be manually triggered by going to Settings<<About Phone<<Software Update. The One S Android 4.1 update is about 598MB in size, so it is strongly recommended that you download this update via Wi-Fi.
According to change-log given on the update notification screen, the update comes with:
- Android 4.1.1, HTC Sense 4+
- Enhanced UI and better performance in camera
- New landing page and Event/Map view in Gallery
- Power management improvement
We can also expect to see Jelly Bean features like Project Butter improvements, Google Now, enhanced notifications, enhanced widgets, and new embedded speech recognizer.
HTC One S update details:
- Version: 3.19.720.100
As most of the Android update released in batches, so you might not see the update right-away, but you will get it in the next few days.
