Can other Droids mimic Moto action gesture shortcuts?

[Android Central Question]

I've had a Moto Z ver.1 for over 2 years. I've been thinking of upgrading to the Note S9 or the Pixel 3. I looked at both in a Verizon store. I goofed around with them but noticed one major issue. Neither launched the flashlight or camera with hand motions like my Moto Z. I ask the sales guy & he said the "Chop-Chop" motion to launch the flashlight & the " Twist-Twist" to launch the camera were only on Moto phones. Is that true? Is there not an app or tweak that can make other android phones do the same thing? I use the chop motion for the flashlight 2nd only to texting every day. I love how I can do the flashlight & camera 1 handed. Its a great feature on such a big phone. I can't imagine having to wake up my phone then open or drag some app to turn the flashlight or camera on. I think most phones have a quick camera trigger like hitting the volume & home button at the same time. Does anyone know if you can get the action gestures to work on other android phones?
Thanks!
