Customer Fault Description:
My iPhone 7 has just started to crackle if I answer a call or I can’t hear the person on the other end. The speaker and FaceTime options for the calls are greyed out too. I have checked my sound and it’s all ok, but have noticed I can’t record a voice memo either. Would greatly appreciate any advice. I am on IOS 11.4.1 and have restarted my phone a number of times with no change.
