My iPhone was working perfectly until a few weeks ago. Then suddenly I could barely hear some callers - or they couldn't hear me. Tried all the obvious things: checking that the volume is high enough, cleaning microphones, checking not on airplane mode … still the same problems. I can, however, hear people (and they can hear me) if I use speakerphone.
Today, I had my phone checked at an Apple Genius Bar. I was informed that my phone was in perfect working order (it’s only a few months old and still under guarantee) - and that I should maybe check for any problems with my network. However, as far as I can see, iD mobile hasn't had any outages. And, in any case, why would this sometimes result in me hearing the other person but them not hearing me - or vice versa?
Any advice or insight appreciated.
