Three days ago, OnePlus released another preview of its Android 7.0 update. Like its other beta releases, the latest one was exclusively available for the 3 — but with no sign of a preview for the 3T, and with only a few days of the year remaining, it seemed very unlikely that the company would fulfill its promise to begin upgrading both handsets to Nougat by the end of 2016.
But in the last few hours of the year, OnePlus said that it had begun rolling out OxygenOS 4.0, based on Android 7.0 Nougat, to both the 3 and the 3T.
