The Sony Xperia XZ1 and XZ1 Compact have started receiving their first update. Arriving as build number 47.1.A.2.374, it’s a security update that brings along Android fixes for the month of October.
Sadly, there’s currently no information on what other changes (if any) are included in the update. As is usually the case with OTA roll outs, it might take some time for the update notification to show up on your device, so be patient.
