Beside the new Android 6.0.1 version, we saw the release of the December security updates earlier this week. Many manufacturers committed to roll these updates monthly to their devices and HTC seems to be keen on jumping to the front of the line with its near-stock One A9.
Owners of the device on AT&T should have started seeing an OTA update yesterday with the security fixes as well as camera improvements, says HTC’s VP of Product Management Mo Versi.
