Make it so you can turn the home button into a home icon icon in the settings.

Go to settings And go to navigation bar and if you have navigation bar set to buttons there there is a option called turn home Button into a home icon  Then turn it on and It should pop up And that's my suggestion for the next update next update of the Galaxy Z fold series.

@morover300 You should check out Samsung's NavStar. It is part of Samsung's Good Lock app. It offers several customizations of the navigation buttons. 

To check it out:

1. Visit Galaxy Store and download Samsung's Good Lock.
2. Open Good Lock and click on NavStar to install it.
