I've noticed on on the liberty GB (currently running v.8) that the call-answer screen seems to have a mind of its own. Sometimes it'll do the normal way most are used to, slide to right to answer, slide left to ignore. But on other occasions it will be a button. Button on left bottom answers, button on right ignores.
Anyone have any clues as to why it flip-flops? And it there a way to force it to do one or the other?
