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
