Apple has announced a service repair program to fix defective iPhone 12 and 12 Pro speakers for free.
A small percentage of iPhone 12 and 12 Pro phones shipped with a defective receiver module component. As a result, once the component fails, impacted devices may have sound issues, including no sound coming through the receiver when making or receiving calls.
The issue affects devices manufactured between October 2020 and April 2021. Apple says in a blog post that it will repair defective devices for free.
To initiate the process, customers should go to an Apple Authorized Service Provider, make an appointed at an Apple Store, or contact Apple Support for mail-in Apple Repair Center service.
