I was playing with a Motorola G72 and noticed this feature by accident: double-tap on the back of the phone to trigger a custom action.
Here is a video showing this feature
This is not the same as double tapping the fingerprint scanner. This phone has a front-facing under-display scanner.
It’s very neat and handy, I hope other phones implement this too.
Update: See this comment for a link to an app that enables the feature on many phones.

This works on Pixels. I have mine set to flashlight.
Back when I had my Mi A1, I used to run a Pixel 2XL GSI ROM that enabled the same feature.
I used that to take a screenshot, and later, show the accessibility menu when my power button and volume buttons stopped working.

chop chop flashlight is the very best feature of the Moto series
Should be noted it’s fairly simple to do this on any Android phone with Tasker.
