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 🫠)
That dialer change was evil. I have switched to Fossify Phone now and use that as a dialer. The Fossify apps are amazing, they also have a gallery and messages app, so Google’s proprietary BS isn’t neccessary.
