Audio IC and Your iPhone 7 Speaker Problems
Another pervasive board-level issue is duping a growing number of Apple iPhone owners. In the past, users ran into iPhone 6+ touch issues which became known as Touch Disease. A surprising amount of iPhone 7 owners are now reporting problems with various audio functionalities. Users will first notice their microphone not working while making phone calls. The fault is known at the C12 pad on the audio integrated circuit chip. Technicians now commonly refer to it as the ‘Audio IC’ or ‘Loop disease’. It is unclear whether the issue is a manufacturer defect or due to regular wear of the device. Apple was recently hit with a class action lawsuit because of this particular issue.
A common indicator of Audio IC disease is an error when using the voice memo app. Reports mention a grayed-out record button or an error message that reads ‘Recording Failed. No audio device found.’ Users also notice their microphone not working during phone calls. The speakerphone and Facetime icons also become grayed-out on your call screen. Many users have also reported their iPhone won’t turn on. Others state very long boot up time when powering up their devices. An Apple icon will seem to hang for minutes on end before finally powering up all the way.
