K9 (X3) Smartwatch Keys Mapping

Is it possible to re-map the back key? I would like to get “multitasking apps” when you keep pushing it.

Sorry That’s True! It’s a K9! I’ll edit it

To all who wants to do this… I have installed this App (not need root):https://play.google.com/store/apps/details?id=com.irishin.buttonsremapper

And now I can access to multitasking pressing back buttom for 2 sec. Much more useful!
