Ok so i have a third party app call
Camera ZOOM FX and i would like to use the app as default like opening it from lockscreen.

My current version is android marshmellow 6.0.1 and there is a shorcut where you press home button two time and the camera open but its the default so how i can change it to czfx.


I have try default everything and it does not give me option to pick which app.
