Apple has posted a service bulletin for owners of the iPhone 12 and iPhone 12 Pro.

According to the tech giant,  a "very small percentage" of iPhone 12 and iPhone 12 Pro models in   are suffering from an issue that is affecting the phones' speakers. As a result, Apple said in a statement that "If your iPhone 12 or iPhone 12 Pro does not emit sound from the receiver when you make or receive calls, it may be eligible for service. Apple or an Apple authorized Service Provider will service eligible devices, free of charge."

To be clear, this problem is affecting only the iPhone 12 and iPhone 12 Pro and is not impacting the iPhone 12 mini and iPhone 12 Pro Max.
