I have an intermittent problem when receiving calls on my mobile. I can hear the caller but they can't hear me. Often they hang up and call back and this fixes the problem. I also try restarting my handset but the problem still recurs.
I use a galaxy A10 handset but also tried the SIM in an iPhone 5s and got the same problem.
It has happened in different locations and at with different callers. It is not a signal issue as the call connects fine but there is absolutely no sound at all from the start of the call.
It's having an affect now I'm working from home and I am missing work calls. Help please.
