Sony Xperia XZ2 Premium receiving the Android 9 Pie update

Although it didn't quite happen as planned since the first three Xperia phones have been updated to Android Pie only this month, at Sony kept its promise in regards to the Xperia XZ2 Premium.
The folks over at XperiaBlog report Sony has already kicked off the Xperia XZ2 Premium Android Pie rollout, and they have screenshots to prove it. The update adds the November security patch and some changes to the camera interface.
Unfortunately, no detailed changelog is attached to the update, so we can't be sure if Sony implemented any improvements to its only phone with a dual rear camera, other than a new interface. If you've got the update, let us know in the comments if there are any major changes besides those that come with Android Pie.
