Apple has made the group chat function in FaceTime unavailable after users said there was a bug that could allow callers to activate another user's microphone remotely.

The bug was demonstrated through videos online and reported on this week by tech blogs. Apple's online support page on Tuesday said there was a technical issue with the application and that Group Facetime "is temporarily unavailable."
