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.

      Wow! I bet most iPhone users don’t know this exists. This is more like a usability feature than an accessibility one. It even supports triple tap!

    Pixel phones also have this feature, called quick tap. Quite handy to turn on and off flashlight for example.

    Reading the comments, it looks like there are lots of other phones doing this.

    Personally I use it to turn on the flashlight on my Pixel 6.

    The Pixel series have this. It’s called Quick Tap.

    Combined with Tasker, you can make it do anything – if the existing options aren’t enough.

      Cool. It’s incredibly useful. Didn’t know Pixels had this too.

    On other devices, you can use Tap, Tap but it may not work as well

      Requires root or a compatible Pixel device…

    Samsung has this as well as triple tap under RegiStar via Good Lock, but it randomly just stops working. It was great at first, but now I don’t even try to use it because so often it just doesn’t work.

    Quite a few phones have similar features. Samsung users can use GoodLock to use the back tap too.

    But when I tried in the past, I didn’t like it, too many false triggers.

    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.

    I miss my Motorola phones.

    Had nothing but Motorolas since my very first Android. Absolutely loved the gestures and hands free interaction. Went through a series of Moto phones over the years until I accidentally destroyed my last one and needed a new device ASAP. Ended up with a Samsung S21 which is a perfectly fine phone,but it doesn’t have the personality of any of my old Motos. It does have a much better camera though than any of my Motorolas.

    I don’t want to buy a new phone any time soon, but I definitely want to go back to Motorola.

    The two underneath it are lifesavers too.

      Yeah both are brilliant design ideas. Only someone who has used a moto phone knows what we mean.
