Nobody hears me during a call, but it is not a mic - Samsung Galaxy S7 Questions and Answers

I caught such a bug - during a call I hear, but nobody hears me (at all). All other apps that use a microphone perfectly worked (voice recorder, fb messenger call, skype and so on). I made 10 calls in both directions, the 'microphone' did not work. With a speakerphone and bluetooth headset nobody heard me too. So that's why I believe that was internal call bug in the firmware, not a mic problem.
It was fixed only with rebooting (off and on).
I happened with my SM-G930T with lastest firmware (G930TUVS4BQJ2). I have been using it just for 13 days, but this is a very unpleasant bug and I do not know what to do. Should I change it, or is it a rare software bug? Or maybe it is a bug only in T-Mobile firmware?
Did someone encounter the same problem?

Strange Muted Outgoing Call Mic Ongoing Issue..

Hello all,
I am making this thread because I am having a really strange and frustrating issue that I am hoping can be solved before I am forced to get rid of my phone. I have a factory unlocked SM-G955U running the most current stock software. Basically my issue is my phone randomly mutes my mic during outgoing calls. I can hear the person on the other end but they can't hear me. Sometimes all I have to do is hang up and call back to fix the issue. Other times, the only way for me to fix the issue is for me to restart my phone. Strangely if I hang up and the other person calls ME back, then the problem is instantly solved. I thought this was limited to actual phone calls, but I had the same issue happen today with and outgoing Whatsapp call as well. I can confirm the problem is 100% isolated to OUTGOING calls and has no effect on incoming calls. I would have to assume this issue is software related and not hardware related given the fact this is only happening randomly on outgoing calls and has never once happened on incoming calls.
Ive done all of the basic troubleshooting and even removed my ultra thin phone case with no change in results.
Any help would be much appreciated thanks!

Can't hear caller?

Appreciate any help.

Incoming/Outgoing calls issue on the G7 One LM-Q910UM

I have been experiencing incoming call issues. Also outgoing call issues but not as frequent.
Incoming calls while on Android 10 are silent. I cannot hear the caller and they cannot hear me. If I enable speaker phone I hear them and they hear me fine, I then can disable speaker phone back to the ear piece and all is normal again. I am not sure if this is for carrier specific incoming calls or just a sw bug or both...
Outgoing call issue has happened a couple times. In this circumstance I made a call put it on speaker phone. It was on speaker for a while the call was fine I could hear everything so I muted my side until I needed to speak. When I un-muted they could not hear me. I took it off speaker while un-muted and still nobody could hear me. I had to hang up and switch sim cards back to my V30+ because of this issue.
I have yet to test other dialers or phone apps, to see what might be happening here. Anyone have any suggestions to check logs or is there a way to get to a service menu to troubleshoot?

Question Problem with sound in voice calls in messengers after upgrade to Android 13

I have Samsung galaxy A32 5g ,model sm-a326u. A 2-3 weeks ago it received OTA upgrade to Android 13 Tiramisu. And after that upgrade i can't use any voice calls via WhatsApp ,Viber, Google voice, skype, Signal, etc. - anything that uses microphone and internet calls. The other side hears very distorted voice, not recognizable at all. When I use test calls on Skype I hear the same, totally unrecognizable voice (can't test in WhatsApp or Viber, there are no test call options). I thought that is a mic problem, but no, video or audio recording from camera works without problems, online mic tests are passed too. Regular phone calls are fine, but no Google Voice calls. Also, if i use any Bluetooth headphones (I tested 3 different), there is no sound coming from me in internet calls to other side.
Please help
Looks like people have all kinds of sound problems after Android update, reported here Samsung Community forum and here, and here
I tried a few things to fix this issue: clear the cache partition of the phone (doesn't help at all), reset all network settings (doesn't help at all). Only Factory data reset seems to fix it. But it is not the best solution, a lot of apps and data can't be easy restored after that.
I had same issue on various Android 13 roms. Trying different roms did NOT fix the problem.
The FIX is to
Disable Bluetooth A2DP hardware offload
Now all the messenger app's audio works perfectly!
Enjoy!
