No sound in phone calls

[robohyrt]

There is no caller sound audible in phone calls. Total silence. Doesn't matter who the caller is, or whether I receive a call or make one myself. I hear no sound.

This happens frequently enough that I can't rely on using my phone's main function: Making phone calls.

It will sometimes fix itself if I restart my phone, but will happen again sooner or later. Sometimes restart won't fixing it either. Clearing the phone app's cache is also useless. All software is up-to-date.

I can't believe this happens in a flagship "phone" in 22. I mean, after all, this is a "phone", and I'd expect it to work like one.

I appreciate if there is a permanent solution, and explanatation to why this is happening.

Have you removed SIM, or upgraded your SIM

Ok, basics first
Like a radio sometimes it looses signal. It happens, despite a full set of bars.

If rebooting only sorts it for short times, it's more than likely network or sim card.

If this is your first 5g phone (not 5g ready) then you need a new SIM card.

You can try this....
Turn off handset
Remove SIM card
Give it a wipe
Replace SIM card after 1 min
Turn on handset
... Hopefully that sorts it.

If not, speak to your network ... If O2 then good luck!

Sorry friend but this is a much larger issue than just removing the sim or upgrading it. If you check all the samsung forums, so many people including myself are experiencing this no audio issue which Samsung seems to be doing zero about! Messenger call audio and whatsapp audio are working perfect.

FYI, i recently upgraded the sim and it made no difference so unfortunately that's not the solution here. Really getting sick of this company, that's been since April we've had this issue.

Let's say 20,000 handsets from Samsung are faulty, just plain old, ***** up and faulty ... What percentage is that

I'll tell you, it's 0.2% (give or take)

I think that's more than except able to be faulty

Then let's put this into more perspective

How do the sums work now?

Sometimes a faulty handset is out there.

This issue has nothing to do with SIM card nor connection. It is most likely a software issue, some bug that interferes with the audio thread or the audio output when using the phone.

Agree! This happens from time to time and I need to reboot the phone to fix. So fcking annoying

Hi,

I have the same issue in the UK. S22 bought directly from Samsung shop.

I get your point about faulty units and percentages. However, the low percentage should also mean quick warranty fixes or replacements.

Has anyone tried or had luck with getting a replacement?

[Specdee]

Exactly the same problem with S22+ in the UK. Really frustrating. Reboots worked before at least. It is not even working today...

Have the same issue in Poland. My brother same. Anyone found any fix?

I just ran into the issue once again, as I have more debugging option on the far end I checked behaviour there.

In regards to the problem the Phone App (plain GSM call only) seems to have issue with speaker & mic, according to my trace my S21+ is receiving audio (far end is sending) but not playing it to the speaker just dead air, also no audio is send or if it is send (not sure how much provider helps out) it is also just dead air, received packets if any are there look all like this:

But speaker and mic are just working fine meanwhile with other apps like Signal/Whatsapp.

Workaround: Restart phone fixes it

Haven't tested to force stop the app, yet to see if this might also fix it temporarily.

Also let me know technically on why this should be a problem with the SIM? either it is working or not, if it is a SIM problem you should be prompted for the SIM PIN as an indicator for a SIM read problem.
