Sony has started rolling out a new update to its Xperia XZ and X Performance smartphones. It's a minor, bug-fixing update that bumps the build number from 39.2.A.0.361 to version 39.2.A.0.374.
This is the second update that has been rolled out to these devices ever since they received Nougat. The last update brought along Android security fixes for the month of December.
As is usually the case with OTA roll outs, it may take sometime for the update notification to pop up on your device's screen. Meanwhile, if you feel impatient, you can manually check for the update by heading to the Settings menu on your handset.
