As a longtime Android user and tech expert, I've helped countless people adjust to OS updates. You're probably used to long-pressing the power button to turn your phone on/off, restart, lock, or access emergency options. (Android 10 even added screenshots briefly.)
After upgrading to Android 12, that long press now launches Google Assistant instead of the shutdown menu. This deliberate change prioritizes Assistant access, but it's customizable.


You can still open the power menu by pressing power + volume up together—great if shutdowns are rare. For quicker emergency access or classic long-press behavior, here's the reliable fix:


And you're done!
The Gestures menu unlocks more: Set Quick Tap (double-tap back) for screenshots, apps, or Assistant. Double-press power for camera, revert to three-button nav, or use face-up/down for Do Not Disturb.


Tweak these for a personalized experience—proven ways to boost usability based on years of testing Android features.
