Apple has reportedly directed its service providers to run audio diagnostics on the affected devices and ask users to manually disconnect any audio accessories connected to their iPhone to replicate the problem. Now it seems that the tide is turning as the most expensive phone was the world's best-selling smartphone in the first-quarter of 2018, according to Strategy Analytics.
Apple is said to have admitted that a major bug exists in some of its iPhone 7 and 7 Plus models.More news: Microsoft Build 2018: The 3 key takeaways for business leaders
It sounds like there might be a connection between the iPhone X back camera failure and the front TrueDepth sensor system. The telephoto lens wasn't working, hence the problems with Face ID. The lenses differ on which they do.
In an internal memo sent to Apple's Authorized Service Providers, the company said that some iPhone 7 and iPhone 7 Plus owners running iOS 11.3 or later have complained of a grayed-out speaker button when they place calls. "My front facing camera works fine but the rear is messed up, which leads me to that conclusion". Run AST 2 on the customer's device to check the camera.
Customers facing the iPhone X Face ID issue can arrange an appointment with an Apple Authorized Service Provider via the Contact Apple Support page. In the past, users have come forward linking failures of Face ID and the rear camera. There have been instances where users explained that features like pano, slow-mo, and time-lapse still worked, while others did not. Apple is offering an exception for this specific problem if your iPhone warranty has expired.
