Sony has started pushing out a new update to the Xperia XZ1 series and XZ Premium smartphones. Carrying a build number of 47.1.A.12.205, it's a security update that brings along Android fixes for the month of June. 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 may take time for the update notification to pop up on your unit, so you'll have to be patient. Via
