On my Samsung Galaxy S 4, I can add contacts to the "ICE - emergency contacts" group. When I initiate the emergency dialer, there are four gray buttons with plus signs. Pressing any one of them brings up a list of the contacts I added to that group.
Each of the buttons acts the same. I would think that you should be able to assign one contact per button and have the button show a name or relation.
Is it possible to do this? How?
