A bug has been discovered in the iPhone's video calling app FaceTime, which allows callers to listen to their recipient before they have answered or declined the call.
The bug was originally shared on Twitter and people are nervous about whether anyone has listened to their audio without their knowledge.
After the original bug was reported, Buzzfeed found that with the push of a button the caller can also see video of the person they called.
Newshub tested the bug between an iPhone 6s and an iPhone 8, both phones operating on iOS 12.1.2, and the glitch was shown to be legitimate.
In a statement, an Apple spokesperson said the company was "aware of the issue and we have identified a fix that will be released in a software update later this week".
It is unclear when exactly this update is scheduled.
How to test whether your FaceTime has the bug
- Make sure both iPhones have iOS 12.1.0 or above.
- On one phone, open FaceTime and call the other using the video call.
- While the call is ringing, swipe up to show the full menu screen, and click where it says 'add person'.
- Type in your own number and add this to the call. Now you should be able to hear audio from the person you called, even if they haven't accepted the call.
- If the call recipient presses the volume button to mute the call, their video function will also turn on and you will be able to see video from their phone.
Users have the option of disabling FaceTime in iOS settings, which, if you have an iPhone and are concerned about the bug, will provide a defence till the update is ready to download.
