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.
(Yes, I have no idea why the Assistant is in German when the phone is set to English either 🫠)
Not just new ones. Last month my mom asked for help because she could no longer turn off her phone. I checked the settings and the power button had been assigned to the assistant.
