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 🫠)
Is that a nothing?
Yes, the Nothing Phone 1. I reset it, because I switched to a Unihertz Titan 2 now and only use it as a USB webcam. :)
