Inline with expectations, HTC has announced that unlocked units of its HTC 10 smartphone will receive the nougat update starting November 25. The announcement was made by the Taiwanese company's VP of Product Management Mo Versi on Twitter.
Happy Thanksgiving! HTC 10 unlocked owners will receive Nougat OS update tomorrow morning! Enjoy!— Mo Versi (@moversi) November 24, 2016
Given that the tweet doesn't mention any particular region, it'd be reasonable to expect that we'll be seeing a global roll-out of the update. The roll-out, however, could be phased, so it may take sometime before the update hits your device.
