iOS 11.3 brought many improvements in terms of both security and performance, but is everything so rosy? As it became known from messages of users of Reddit portal, this update did not affect the work of microphones of iPhone 7 and 7 Plus in any way.
The problem occurs during a phone conversation or FaceTime. The microphone and speaker icon stops being active, as a result of which the interlocutor can not hear the caller. Rebooting the system does not solve the problem.
According to the MacRumors edition, Apple is already aware of this problem and sent out the appropriate instructions to authorized service centers for correct diagnosis in case of appeals in this regard. Apparently, the problem is serious, and it can not be fixed simply by updating it. In the event that the defect is confirmed, the repair will be performed at Apple's expense, even if the official warranty for the device is no longer provided.
The company stressed that this problem affected only a small number of smartphones, the iPhone 7 and 7 Plus.
This is not the first time that the software update leads to hardware problems. The recent story, when the new version of iOS blocked the work of non-original displays on the iPhone 8, iPhone 8 Plus and iPhone X – a vivid confirmation of this. Let's hope that in the future Apple will be more careful in testing its software.
