A significant bug has been discovered in FaceTime and is currently spreading virally over social media. The bug lets you call anyone with FaceTime, and immediately hear the audio coming from their phone — before the person on the other end has accepted or rejected the incoming call.
Here’s how to do the iPhone FaceTime bug:
Start a FaceTime Video call with an iPhone contact.
Whilst the call is dialling, swipe up from the bottom of the screen and tap Add Person.
Add your own phone number in the Add Person screen.
You will then start a group FaceTime call including yourself and the audio of the person you originally called, even if they haven’t accepted the call yet.
You can listen in to soundbites of any iPhone user’s ongoing conversation without them ever knowing that you could hear them. .
Apple has said the issue will be fixed in a software update later in the week. Until then, if you are concerned, you should disable FaceTime in iOS Settings.
