I want to remove old saved networks that are no longer in range. I can forget visible networks, but out-of-range networks are not visible anywhere so I can't do the standard long-tap => "Forget Network" action.
There is no option for "Saved Networks" or "Manage Networks" under the built-in Wi-Fi app's "More" menu.
I have tried a third-party app, WiFi Manager, where the networks are visible but reported an error on forget:
Android 6 allows apps to change (edit password, forget) only those networks that were originally "created" in same app.
I quite distinctly remember being able to view saved networks on previous Android phones...
My phone is rooted, so methods requiring root are acceptable, but it's better if that's not necessary.
I have an Australian (CSC XSA) Galaxy S7 Edge (SM-G935F).
Apparently this was a problem with the S6, where the 'solution' was to use third-party Wi-Fi management apps that no longer work in Marshmallow.
But that no longer works, as per the error message above...
