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?
Thanks for the comments so far. All updates are the latest versions and without wifi calling on then the other people couldn't hear me at all. With Wifi calling it is a little better. After checking some bits online I did a full factory reset of the phone and started again. Its not perfect but it is much better now with wifi calling on. I can actually have conversations now and very occasionally the sound drops out and the other person can't hear me. That's a vast improvement on them not being able to hear anything from the second the call started.
The issue is when I call others and when they call me. I don't actually know anyone else on Three network everyone I have tried speaking to has either been a different network or a landline.
