Yesterday my brand new shiny OnePlus 3 arrived. My old phone was only Jellybean and so I'm new to Marshmallow. The OnePlus 3 has a setting to use the capacitive recent/back buttons, which I like. The only snag is that I can't see how to bring up an app's "Settings" menu. (If I switch the OnePlus back to using on-screen soft buttons, then some apps have that vertical three-dots button showing, which works fine.) Is there some way of getting at an app's settings menu when the capacitive buttons are switched on?
