Meaning most likely than the three work together for noise cancellation. I.E the query was about quality of call not that the mics were not working.
well support didn’t put it that way (that it is only related to noise cancellation) unless i misunderstood something.
plus when the other side doesn’t hear me at all, already when just one mic is covered, it has to do with the problem i initially explained:
I see you have tested the mics [Dial
#*#*#2886#*#*] and they all seems to work so it is a quality issue which may be down to some app interfering with the default use. Have you tried using in safe mode for a day or two ?
