    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
