I'm having issues with the on screen soft buttons on some of the newer Windows Phone (Lumia 640 etc.). The soft buttons occlude the bottom portion of the screen. The on screen keyboard is fine - it moves around as you show and hide the on screen buttons (swipe up from off the bottom of the screen), as does the toolbar.
I've tried trawling through the various ViewManagement namespaces in the Universal bits but nothing seems to give you a value or event for these buttons!
ApplicationView.GetForCurrentView(); etc.
Has anyone got any pointers?
