Apple has disabled the Apple Watch Walkie Talkie app due to an unspecified vulnerability that could allow a person to listen to another customer’s iPhone without consent, the company told TechCrunch this evening.
Apple has apologized for the bug and for the inconvenience of being unable to use the feature while a fix is made.
The Walkie Talkie app on Apple Watch allows two users who have accepted an invite from each other to receive audio chats via a ‘push to talk’ interface reminiscent of the PTT buttons on older cell phones..
