It is I think an inevitable consequence of trying to design something to fit onto a phone-sized screen that you do not have the luxury of labelling all the buttons and the user just has to get used to it. That is an observation I have discovered about Android generally having now used it for a few weeks in a variety of apps.
In any case, it is not like there is no precedent for making unlabelled screen space clickable even in the BBO mobile app. We can already click on the final contract to get the auction, or the score to date to get the last trick revealed, and it is only by actually clicking on these areas that the user ever becomes aware of the potential.
I agree with what you have said. These issues apply to the iOS as well as Android.
