My watch 6 classic mic stop working also. I'm nit sure when this issue started but Im sending it to UBREAKIFIX BY ASURION to be looked at and/or repaired/replaced. But after talking with other galaxy watch users (watch 4, 5 & 6) it appears that this is a on going issue with the watch mics. Can anyone else here say they've been having this same issue?
I've sent my Classic 6 watch in twice to Samsung with the same issue. I could hear people but they couldn't hear me during a call. The first time, this is what they reported:
Original Problem: POWER - POWER - NO POWER AFTER UPGRADE
Problem found: TX AUDIO - MIC - LOOPBACK FAILURE
Solution: S/W UPDATED - REPLACED COMPONENT
When they sent the watch back, I was able to have a convo using my watch. Well, over the last couple of weeks or so, the same issue occurred. I went through troubleshooting. Ended up sending the watch back to Samsung. This time, they have noted that they are sending the watch back unrepaired. I called and they said that means they couldn't get a part, and/or the unit is unrepairable. So I'll get a replacement or a refund. Unfortunately, there is definitely a problem with mics on these watches.
