There has been a serious bad FaceTime bug which allows users to eavesdrop on others. Though Apple has automatically made FaceTime unavailable and is trying to fix this bug.
The bug is so bad that it allowed users to listen in on the people they were calling when they did not pick up the call. Sometimes, the bug also allowed callers to see the video of the person they were calling before they picked up. Which is a serious threat to one’s privacy and we hope Apple will fix it ASAP.
Meanwhile we advice our readers to disable your FaceTime ASAP.
