There is something of a workaround. In settings choose the gesture option, then choose the option to disable gesture hints so it isn't visible at all. You still have to use the swipes for all the buttons but you don't lose any screen real estate. Also, to access the Google assistant swipe up the middle and hold it. If you want to customise the look of the navigation bar, go to the Samsung store and install an app called Good Lock . This app has various add ons that you can install. Once you have Good Lock installed, tap on Nav Star down the bottom of the list to install that add on. You can also down load the Quick Star add on which gives you the option of moving the clock back over to the right hand side where we are used to it. And all the add ons are free. Hope this helps!
