Hi
Just received a brand new (sealed) boxed Sony Xperia XZ3 (Model H8416). It is currently on Android 9 Build number 52.0.A.1.215. However despite going into settings , system, Software update and System then refresh, it says "Your device already has the latest available system updates". I've had the phone for about a month with no sign of any update to Android 10. I have also tried the Xperia Companion but it says that everything is ok.
So basically how do I go about upgrading my XZ3 to Android 10.
