I want to change the back button hard press assignment too. You can do it with the home button, why not with the back button. I don't want to use Samsung pay so I don't want to hard press the back button and get Samsung pay. Please how can we change it to something else. I tried to do it with the app and the watch settings and even though I uninstalled Samsung pay from the watch, I still get Samsung pay when I hard press the back button. Help please and thanks
I need this too! In water mode the back button is the only one we can use.
I need to assign long press back button to messages app so I can see missed messages in water mode.
