Tapping "Set to Screen" sets the width and height to -1 for you? That's so strange. I will run some tests today on my BOOX Tab X to see if I can find a way to reproduce that. The width and height that are reported take into account screen decorations/bars, such as the navigation bar at the bottom of the screen or the status bar at the top of the screen (if it is visible). MobileSheets is just using the value that the SDK is returning for the application window size instead of using the raw dimensions of the tablet (as rendering to the raw dimensions could lead to the full screen not being utilized due to those decorations/bars). The information about the width/height isn't saved in the database anywhere.
