Android Pie has been out for two months now, and Sony is finally serving up a slice of Pie to owners of the Sony Xperia XZ Premium and the Xperia XZ1 and XZ1 Compact. The update was originally announced for October 26; some late-stage bug-busting pushed the update back, but the update is rolling out now to the Xperia XZ Premium, XZ1 and XZ Compact in some markets.
This update is a big one — you'll definitely want to download it over Wi-Fi — and while it bring a lot of Pie's loveliness, it does not appear to include Android Pie's new navigation gestures, which could be seen as a "feature" depending on if you love or hate the new method. There are several additions and refinements to the camera app and offerings, including 1080p Super Slow Motion and a re-branded Portrait mode. This update was supposed to go up last month, which may help explain why it brings the October 2018 security patch instead of November.
We haven't been able to see the official change log show up on the Sony Mobile support site yet, but the update is slowly making its way out, just a few weeks later than scheduled. And yes, no one likes late updates, but look at it this way, you don't have to wait until March to see Pie like Xperia XA2 line does.
