Apple says it's working on a fix
The Verge reports that a statement from Apple said the problem was limited to a “small number” of cases, and that Apple is working on a software update to fix the problem. The problem apparently only happens during some phone and FaceTime calls, and not when the earpiece is used as a loudspeaker. The crackling sound is actually the second problem that Apple has acknowledged related to its latest product rollout. Apple also said that there were some issues with the Apple Watch 3 connecting to LTE. As the first model with LTE support, this was a big reason to purchase the device. Apple said this will also be fixed in a software update.
Apple did not immediately respond to Fortune‘s request for comment.
