In my case back brings me to kodi homescreen. Which is correct behavior. And B to go back to the previous folder.

Controller needs a direct way to kodi homescreen and back button is for that.

Not sure if im understanding.

If you want back to act as b button, just copy b button on back button, on joystick.xml.

But if you are browsing subfolders, you will have to press back or b several times to get to kodi homescreen if you change that.
