HTC has started rolling out Android 7.0 Nougat OTA (over-the-air) update to its One A9 smartphone in India. The update comes with software version 2.18.707.1 and is 1.05GB in size.
Along with the Android 7.0 OS, the update also brings the latest Android security update by Google and some system enhancements.
As we know the firmware updates are rolled out in stages, so it may take a few days before they reach all the devices out there. Notification for the update should automatically pop up on your device when it is available for you, or you can check it manually by heading to Settings -> About Device -> Software Update.
