Following through on their commitment to get Android Oreo updates out to various devices, Sony has begun rolling out the latest Android build to the Sony Xperia XZ and the XZs today. The build, version 41.3.A.0.401 for those keeping score at home, comes in at just over 1.2GB in size and brings all the goodness of Oreo to these two devices as well as some Sony specific features.
Xperia Actions comes with this update and it gives recommendations on the best configuration for the device based on scenarios. They have also added Smart Text Selection which suggests actions based on the content of selected text.
Due to the size of the upgrade, it is only going to be available to download via WiFi and you will want to make sure you have at least 70% of battery life remaining prior to updating (or have your phone charging via AC). The update will take about 15 minutes to complete including a reboot after it is done.
Sony has a wide range of Xperia devices that they have committed to getting Oreo out for in 2017 and 2018. The Xperia XZ and XZs are the latest to get it with more expected in early 2018. Remember that the XZ Premium already has had the update roll out to it.
Keep in mind that the update is only for unlocked variants of these phones.
