Pressing and holding the Power button alone will bring up Bixby instead of powering off your phone, but you can change that. Press and hold the Volume Down and Power buttons, then tap Side key settings then tap to select Power off menu under the “Press and hold” header. Next time you press and hold the Power button, you’ll get the Power Menu instead of Bixby. However, if you just want to restart your phone, pressing the Volume Down and Power buttons at the same time and holding them for about 15 seconds will cause your phone to reboot. Keep pressing them when you see the Power menu and your phone will turn off. Let go of the buttons when you see the startup logo flash on the screen and your phone will resume turning on.
If you use one finger, the panel will only half open and you’ll need to swipe again to pull the panel down completely.
