How does the green view screen work and how do I view it?

To quickly access green view, once in the in-play menu swipe left to right to view.

X5 has green view functionality allowing you to see the shape and layout of the green on a hole. Within green view you can alter the position of the pin by clicking 'move pin' then using your finger or crown to adjust the position on the green. To confirm the pin position click the crown or tap the tick on screen, this will then give you an updated distance to the pin position.
