How can I active gesture navigation (hide the navigation bar)?

Android has always featured navigation buttons, including a back button — but they’re now going away with Android 10 in favor of a new gesture-based navigation system.
There’s no gesture indicator on the screen under new gesture navigation mode, but you can switch back to the three-button navigation system of old if you want to.
Just go to “Settings” -> “Advanced features”-> “System Navigation” to choose the right option for you
