Android Oreo has been slowly rolling out to devices, and with it comes a number of improvements to Android. Some of the changes include Picture in Picture support for many applications, access to a new Autofill API, fingerprint gesture support, rootless Substratum through native OMS support, and a whole lot more. Many OEMs have started to roll it out the update to their devices including OnePlus, HTC, and now Sony with the Sony Xperia XZ and the Sony Xperia XZs as reported by users on our forums.
The update (build number 41.3.A.0.401) comes with all of the expected Android Oreo features, along with the November 2017 security patch. This means users are protected against the likes of the WiFi KRACK exploit which we heard about last month. We do not know yet if the device supports Project Treble, but Sony has usually been more open to development on their devices with the Sony Open Devices Program, along with being firm believers in AOSP. Either way, the device should see unofficial upgrades past its official End of Life with Sony.
This update seems to be rolling out globally on both the Sony Xperia XZ and the Sony Xperia XZs, according to XperiCheck. Users should expect to see the upgrade in the coming weeks if they don’t have it yet as OTA updates tend to be staged rollouts so that if there are any bugs that the rollout can be cancelled before too many users are affected. The update so far seems (mostly) stable and fast, but further testing is necessary before any conclusions can be made. Users are currently reporting some Bluetooth bugs on the Sony Xperia XZ Premium, but hopefully the XZ and XZs are unaffected.
