It might soon be possible to use Google Assistant to power off your Android phone. 9to5Google has been digging around the beta versions of Android 12 and Search and found clues leading to this option. With Android 12, Google is adding a long-press to access Google Assistant. The dilemma this feature brings is you can't find a way to turn your phone off when you select this option. One potential solution the site found is adding a power button in Android's quick settings menu. Another is pressing the Power and Volume Up buttons to access the power menu. And then, there's also the option to tell Google Assistant to "Power off" your phone.
But since the features aren't live yet, it isn't clear if the voice command will immediately shut down your phone or open the power menu. It isn't also clear if this feature will be exclusive to Pixel devices or Android 12. When we get more details, we'll be sure to update you.
