Call sound issues - others can't hear me during calls

Hi there, 

Ever since I got my Samsung Galaxy S21 I have an issue where when either making or receiving calls I can hear the other person but they can't hear me. 

Initially I thought it might be a signal problem but it happens wherever I am, I have even turned on wifi calling to get around signal issues. 

If I call via whatsapp or facebook messenger then it is totally fine so its not a problem with the microphone. It happens whether i'm using the phone as normal or with earbuds. 

In addition sometimes when someone calls I press the button to answer the call and it says it has answered but the phone is still ringing so the call isn't actually connected. 

It feels like it is an issue with the phone and not my signal as with old phone (S10) it was fine in the same areas and no issue.

Any ideas on how to fix it?

 Same issue here. It's really frustrating that a top line phone can't be used as a phone!! (the other end can't hear me on 90% cases)

I read somewhere else that if you "downgrade" the type of mobile network from 5G, it works (I've set 3G/2G for both my SIM cards, because when I had 4G selected I had the same problem). I tried it out (eliminating the automatic choice) and for now it works... waiting for a more permanent solution though!
Hope it helps!

I'm having an issue when I first call someone they can hear me but I can't hear them. When I hang up then call back I can hear them perfectly. I have switched the phone off and on and it's still the same.

I have same problem. At least twice to 3 times a day when I ring out I can hear them but they can't hear me. So I ring back and it works. I know of others with same phone and same fault. Its completely unprofessional as I use my phone for work everyday.

I have found a fix for myself. Just went to settings, connection, mobile networks and then disabled VoLTE calls sim 1. Restarted and hey presto, I could start making calls again.
