HTC has announced that the unlocked variant of the HTC 10 is now receiving the update to Android 7.0 Nougat in the US. You should now be seeing the update roll out, though like with all rollouts, it might take some time to get to you.
The Nougat update brings lots of new features like an improved Doze mode, better notifications with quick replies, split screen mode, and a lot more. It’s definitely a nice update to an already great device.
If you have an HTC 10, head to Settings > About to check for updates! And if you have a carrier model of the HTC 10 or HTC One M9, you should see your Android 7.0 update early next year.
