Who would need to press the power button to actually turn off or restart the device, right?
The setting to change this is also pretty much buried under Settings -> Special Features -> Gestures.

it’s almost like they should have just gone with both volume buttons, that way it doesn’t matter if one manufacturer uses volume up and volume down and the other manufacturer uses volume down and volume up
