Cannot hear person in calls

[Gary100]

Hi

I have an S24 and for some reason today when I make a phone call I cannot hear the person at the other end, but they can hear me perfectly fine. I can't even hear when the phone is ringing when I dial it. The audio works fine on everything else, and I can also make WhatsApp calls and hear perfectly fine, but if I just try to do a normal phone call it doesn't work. Is this a known issue and if so is there a way to get it working again?

I put my SIM card in my old S20 and I can make and hear calls perfectly fine so it is not a SIM card or network issue. I also downloaded the Google phone app and having exactly the same problem with that.

Thanks

Hi,
Is it working on speaker phone? If you're using a case, then also try it without.

No, speaker phone doesn't work either and I've also taken it out of the case. I tried using my Bluetooth earbuds and I don't hear anything with them either

Thanks, There's a diagnostic you can use via your Samsung members app in the Support section. Give it a go and post back with the result.

Factory reset phone

It says everything is fine

Will that lose all my settings and apps and data etc?

You can backup your files

You need an usb to store all your things like settings contacts app data and etc.
