Apple adds an extra year to the eligibility window for an iPhone 12 service recall program launched in August 2021. This program targets iPhone 12 and iPhone 12 Pro smartphones that are getting "no sound issues" because of a faulty component in the receiver module. When Apple launched the program, it covered two years of the affected units from its first retail sale. The company quietly updated the support document to extend the coverage to three years.
Apple said at that time a "very small percentage" of iPhone 12 and iPhone 12 Pro devices "may experience sound issues due to a component that might fail on the receiver module." The company said phones affected were manufactured between October 2020 and April 2021. The requirement to be eligible is that your iPhone “not emit sound from the receiver when you make or receive calls.” If you meet this criterion, Apple or an authorized provider will repair the issue at no cost. But if there are other damages/issues that "impairs the ability to complete the repair," it will fix this trouble first. And that repair could cost you.
