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. Other versions of the A9 are probably bound to follow.

If you haven't seen the update notification, you can head into your phone's settings and check for it. And this isn't the only goodie you'll get before the end of the year. The One A9 is also scheduled to get Marshmallow 6.0.1 in December, so it looks like owners of HTC's latest almost-flagship have struck gold in regards to prompt software updates.

Here are the official update details:
