HTC already said back in August that they were bringing the Android Oreo to the U11, specifically in the fourth quarter of the year. And it seems like the company might be staying true to their word. Twitter tipster LlabTooFeR claims the update is in its final stages of development and will being rolling out between November and early December time frame. HTC hasn’t confirmed the report.
Aside from the U11, the HTC U Ultra and HTC 10 are going to receive Android 8.0 update, too. However, there is no word yet when the update will be coming to these devices.
