Well, looks like most of the issue is me my dry fingers plus some touch screen imprecision. Tapping in place can produce a minor, but distinct spread which is enough to miss repeatedly given the size of the buttons.
That said, occasionally the touch event does not fire, in which case the prompt tends to not respond. Very rarely the prompt works but the touch event does not or the crosshair is drawn over a button with no response from the prompt.
EDIT: notably I have not had any trouble reliably hitting, e.g., buttons in the calculator app. I don't know if there's a UX difference with full screen applications prompting me to be more precise or something else.
