My hearing aids do that if something blocks the grill in front of the mic. Check the holes for dirt, fluff, etc.
Does it have two mics?
Id say its blocked too since it can "hear" tapping. Ive fixed a phone in the past by putting the vacuum cleaner nozzle over the hole (dont seal the gap with your fingers or anything or youll burst the microphone membrane) :thumbup:
I'll give it a shot!!!
