You can use gestures to control incoming calls, glances, and more. Once glances are enabled within the Navdy app, ensure that the 'Gestures' setting is also enabled via Settings > General.
Navdy uses the gesture sensor on the front of the display which should be pointed towards you. Swiping will need to be visible to the sensor which sometimes happens above the wheel or even higher.
Navdy uses two gestures, swipe left, and swipe right. To accept an incoming phone call, swipe left. To ignore, swipe right.
You can swipe left to open glances and swipe left again to read it. If there are pending glances you can swipe left to bring them up. To go back, swipe right, and to close swipe right again.
