iPhone 7 Microphones Freeze And Require Restart To Get Working Again
Hi there, I would be very grateful for an explanation to my problem as I am stumped. I have my iphone 7 128GB where the microphones on the phone decide to freeze up once in a while and require the phone to be restarted in order to work again. The mind boggling thing, for me at least, is the fact that all other functions related to sound work! The speakers work and microphones get detected for example the voice memo’s record button allows me to record audio however no audio gets actually recorded, complete silence! Once this happens all microphones follow, so neither the bottom microphone or back camera microphone work. The phone does have a cracked screen but I don’t believe it has anything to do with it as it is an original screen and the microphone assembly is more or less untouched. I have measured if there is a short on the microphone lines on the dock connector and found none. Is this perhaps Apple’s software issue? Is there any permanent fix to this? Or is this a audio IC fault and by fault I mean a pad connecting the microphone lines to the chip does not have a full connection? I have not said anything regarding a typical iphone 7 audio IC fault as if i recall that problem causes all sound functions to stop working and not just the microphones. There might be an easy fix to this so sorry if I sound a bit stupid. Any help would be much appreciated, thanks Sam.
