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.
It’s been six years since I switched from an X2 to a pixel 2 and I still miss the flashlight chop
I still chop chop the Teracube I’ve had for a while and then go “oh yeah…”
I had two moto phones back to back and then switched to the pixel. Can’t tell you how many times I tried to turn on the flashlight this way before realization kicks in.
