Happy news everyone, HTC has begun rolling out Android 4.3 Jelly Bean update with Sense 5.5 for the HTC One in India. The update should be available within a day or two on your One, just keep a lookout. Its a 705 MB download, therefore it would be preferable to be downloaded on a Wi-FI network when you have time. If you don't see any update notification just go into Settings->About->Software Update and then check for updates.
Sense5.5 for the HTC One brings in Blinkfeed and Video highlights updates as well as some camera improvements. Do tell us if you find something new in the update.
