I am also having this problem. I am running version 0.1.24 on a Galaxy Tab 2 with Android 6.0.1. In the map view, the game does not respond to pressing or dragging anywhere in a roughly-inch-width band on the top and bottom of the screen. However, the lower-left buttons do respond to taps about an inch above where the buttons appear to be. Since there are filler bands on the top and bottom of most other screens, I imagine those bands just are not being rendered in the map view, stretching the screen and pulling the buttons' apparent locations away from where they actually are. Oddly, the selectable locations on the map itself seem unaffected.
