About a couple months ago, we heard from HTC that its flagship U11 will get Android Oreo update on November this year. The company had then reconfirmed that this update will arrive any time during the fourth quarter of this year. No further official confirmation has so far arrived after that about this issue.
However, now a famous Twitter handler namely LlabTooFeR has revealed that the Android Oreo update for HTC U11 is in the final stages of progress and completion, whereas the company will start rolling out the Oreo update for U11 users either in end of the November or early part of December.
Other than U11, this Oreo update will also arrive in other HTC phones too, i.e. HTC U Ultra and HTC 10. However, the definite rolling out time of Oreo for these two devices is yet to be confirmed.
