4 hidden gestures on Android's navigation bar
With gesture navigation on, that little bar at the bottom does way more than go home.
- Swipe sideways to flip between apps.
- Touch and hold for Circle to Search.
- Swipe down for one-handed mode (turn it on first).
- Swipe up from a bottom corner for your assistant.
Menus and gestures vary by phone maker.
