How to find out which script is starting doubletap to wake gesture in options menu?

Hello guys

I need small help.

I have Zopo china-phone. In the options menu, there is "Smart wake" option which enable double tap to wake and other gestures. It works fine, but I need to find where is located the script which is enabling this option. I need it because of tasker.

So, any ideas how to find where this script could be located?
The only thing I could find is in screenshot

Thank you for any idea
