Unlocked single-SIM and dual-SIM units of the Sony phone are seeing updates push out for Android 7.0. Firmware version 39.2.A.0.327 will take its time rolling out.
The Nougat update is behind the schedule as promised by Sony, though it remains true that the X Performance is one of the first to receive it. The Xperia XZ should be next.
This report of the roll-out is based on several tips into Xperia Blog.
