During the last few days, some complaints have been published in the support forum Apple's iPhone 7 and iPhone 7 Plus owners claim to be experiencing poor audio quality during phone calls.
"It's like the phone is hollow and the sound is coming from deep," says one user describing the problem on the forum. It then adds that the issue only occurs on calls.
Lowering the volume seems to fix the problem, but it certainly can't be considered a permanent solution on a high-end device.
Fortunately, Apple seems to know the issue, and according to information it has replacements to customers with faulty devices.
It is currently unclear whether the hardware is harm or software-related. We can assume it has to do with the first, as if the problem existed in iOS, it is almost certain that it was widespread.
The news comes a week after Apple acknowledged and promised to fix an iPhone 7 software bug that makes the new EarPods' built-in remote lightning completely useless.
