PM and UX designer talks.

About a feature on android with viewpager (swipeable views) and a header with buttons.

PM : We need a back button and a close button on the header.
UX : A customer will be confused by both, with the swipe too.

PM : Then we need a close button alone.
UX : Customer will search for back button and not everyone might swipe left.

PM : We need a back button alone.
UX : Customer might not know how to close the view. He can't keep going back back back.

PM : we don't need any buttons.
UX : Customer should find it easy to close or go back.

PM : bruv.
