Hello. How can I power my new Xperia 10 IV fully OFF? A quick press on the power button switches off the screen. Does this also send the phone asleep? All my previous Xperia phones displayed a message inviting me to confirm shutdown. This does not feature on the 10 IV, it appears. Instead, a long press on the power button activates the annoying Google Assistant which I have no interest in. Am I missing something here?

Thanks.
