I had remapped single press to open a different app (leaving double press for Bixby). Now I cannot remap it. I'm not sure if it changed when I updated the system.
Android Version 9
Hardware Version 1.1
Android security patch level November 1, 2019
Go to settings then search Bixby and bbn set it to easy access and it should remedy.
@Samsung_ASNCD6r, What is bbn?
I'm not sure that this screen shot will come out right.
