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 🫠)
I have a first gen iPod Touch somewhere in a box here. It was press once to lock and turn off screen. Hold to get power menu.
Fucking hell, Samsung? I’m typing this on a Galaxy A52 5g. Same thing. Press power to turn off the screen and lock, press and hold for power menu. They did have press and hold for bixby about a year after I bought it, which I disabled, but it wasn’t out of box default.
I’ve never encountered this multi-button power shit you’re talking about outside of old click wheel iPods, or as the force shut down option (equivalent of ripping out the cord on a desktop PC, definitively not the normal/intended power off procedure).
Don’t know what you’ve been using, but this has not been some standard thing forever.
