Group FaceTime calls on the iPhone and other Apple products are still not working properly, after the company rushed to fix a major bug. Earlier this month, it emerged that it was possible to listen in on people through their iPhone by exploiting a bug in FaceTime, the app used to make audio and video calls over the internet. By adding someone into a group conversation, their phone would start ringing – and during that entire time, the microphone would be switched on and allow the caller to hear everything a person was doing.
