Turn advanced gestures on/off

Turning on advanced gestures gives you two additional gestures, previous and next, and also changes the way you make the back gesture and the forward gesture in Web. Having these gestures on or off affects the way you can switch among open applications on your smartphone.

•Previous and next gestures: The previous and next gestures let you move among your open applications without first going to Card view. The previous gesture is a full swipe from left to right across the entire length of the gesture area. The next gesture is a full swipe from right to left across the entire length of the gesture area. Use these gestures when you have more than one app open and an app is displayed full-screen. By making the previous and next gestures, you go from full-screen view to full-screen view of each app. The order of applications is determined by the order that you opened them or arranged them in Card view.

•Change to the back gesture and to the forward gesture in Web: The back gesture still goes from right to left in the gesture area, but you must make a shorter swipe, from the centre outwards. The forward gesture in Web also requires a shorter swipe.
