The Samsung Galaxy S6 Active and Galaxy S7 Active both have a discrete Active button that can be configured to launch two apps (one via short-press, the other via long-press).
The Android Settings UI makes it easy to configure these buttons to launch any installed app.
I want to configure the button to launch the Pro interface of the built-in camera. The built-in camera allows creating of a launcher icon (shortcut?) to launch the Pro interface from the launcher. But I see no way to specify this Pro shortcut for the Active button.
How can this be done?
