HTC U11 will get its Android 8.0 Oreo update before 2018 begins
After being released for the U11, Android Oreo will be made available for the HTC U Ultra and HTC 10 (probably starting early 2018). Other HTC devices might also be updated to Android 8.0 at some point. However, for now, HTC doesn't have anything else to share on the matter.
Alongside various improvements that aren't immediately visible, Android Oreo brings novelties like adaptive icons, a revamped settings menu, enhanced notifications, and a customizable navigation bar.
