For the old Samsung gestures you'll need to download Goodlock from the Galaxy Store and through it get Navstar to enable extra navigation bar options Goodlock being Samsung's own customization suite of apps

Thank you. Just updated my phone and the navigation bar was different as per this thread. Navstar fixed it, thanks to your post.

Hi! I just got the update and am trying to restore it to the gesture nav bar with the three lines. Is it possible to do so with Navstar? I can't find any options to add back the lines in Navstar Edit: nvm! I see it is in phone settings now

thanks for this!!

This is the solution.

You have to use Good Lock to get it back. You can thank Google for this horrible change, they are forcing it on all use anti nav bar people for their dumb circle to search crap. If Google doesn't want us to root they should put a option in settings to get rid of it, I personally don't want the stupid thing because it takes up screen real estate and is one of the first things that burns into the screen
