Those lucky enough to get their hands on a new iPhone 7 have been reporting a strange defect with the device.
When the handset is pushed to its processing limits it has a hissy fit, according to users. Basically, if the phone is working overtime by, for example, running lots of applications at once, it begins to make a faint hissing sound.
The noise was first pointed out by Stephen Hackett at 512 Pixels and was quickly followed by other users reporting the same thing.
In terms of malfunctions it absolutely pales in comparison to the exploding battery issue in Samsung's Note 7 that prompted a global recall recently. But nevertheless, Apple customers and technologists have been debating the exact cause of the curious hissing sound.
"Some suspect coil whine or similar electromagnetic effects, but there's no guarantee that this is the case," claimed Jon Fingas from engadget.
