Software keys are awful. A compromise to save money by not using hardware keys. They take up screen estate (even though you can hide it at times with a swipe). A true flagship phone should not have compromises. They also spoil the look and symmetry of the phone. The bottom bezel would be plain and a waste of space when capacitive navigation buttons could be there. Awful on 950 xl. Perfect on 1520. So... how can we let Microsoft know not to make this awful shortcut on their next flagship phone?
