To the extent that I have been able to analyze the problem here, it would appear that this is the cause.  The question then arises: why does the bounding curve (ellipse) have holes through which the flood-fill leaks, and why is it happening on your specific Android device but not generally?  I'm pretty confident that nothing in BBC BASIC is to blame, so I fear it may point to a bug in Samsung's implementation of OpenGL ES 1.1 on your Galaxy S7 phone.

Does anybody here have a Samsung Galaxy S8 or S9?  If so, can they please check whether the 'ellipses' demo works correctly or not?
