power off using power button

[100GooN]

It was working before but suddenly not working now

When I long press power button, it is showing Bixby, not power off option

How do I revert the setting?

[Invonik]

Settings - Advanced features - Side key - press and hold: Power off menu
Btw, you can power off by press and hold both side key and volume down key.

Mine also does Bixby, but this was default setting. I power off by swipping down twice and tapping power icon as per screenshot. Looks like Invonik answered your question though :)

How do I update my email?
