In an internal document distributed to Apple's approved service providers this week, obtained by MacRumors, Apple said that affected customers may encounter a grayed-out speaker butt during phe calls. The problem may also prevent the affected customers from being heard during phe calls or FaceTime video chats.
Apple's authorized service providers were instructed to first ask customers to discnect or power off Bluetooth headsets or other audio accessories cnected to their iPhone to see if this solves the problem .
If the speaker butt remains dimmed during a call, service providers have been instructed to initiate an audio diagnostic. Affected devices will display a "device can not detect docking stati" or "unsupported accessory" alert in the diagnostic panel, in which case the service provider may initiate a repair for the iPhone. .
If an affected iPhone 7 or iPhone 7 Plus is no lger covered by the warranty, Apple says its service providers may request an excepti for that particular problem. The Apple document does not specify whether the repairs will be performed for free, but this seems likely given the circumstances.
Although this does not seem to be a widespread problem, there have been some complaints about microphe issues iOS 11.3 scattered MacRumors, Reddit, Twitter and Apple Support Communities in recent mths .
It's unclear why iOS 11.3 and later versis unintentially disable microphes some iPhone 7 and iPhone 7 Plus devices. Apple mentis that some devices may require repair, suggesting that updating the software could cause a hardware problem, but that information is missing.
Affected customers can make an appointment with an Apple Authorized Service Provider or the Genius Bar in an Apple Store via the Apple Support appleiphonestop page: iPhone → Repairs and Physical Damages → Can not & # 39; hear through the receiver or speakers → Built-in speaker → Bring for repair.
Apple has not cfirmed this problem publicly, but MacRumors has verified the authenticity of the document with a reliable source. However, outside of our ctrol, some Apple employees may not be aware of or refuse information. In this case, we recommend that you forward your case to a senior AppleCare advisor if possible.
