this problem started suddenly

Reset all settings. If this does not work, backup your phone and restore it.

tried reset, then a restore and even vacuumed the mic and it still won't work while the speaker is activated

use of earphones uses mic normally

is there some echo cancellation circuitry that could have failed?

Is there any possible chance that your phone was exposed to water?

i am trying to clean the oriface and that has helped, so i think this is a simple mechanical problem

thanks to all for advice
