S23+ Bluetooth not working for phone calls

[csdall]

Hello all!

I am having issues with my new S23+ and receiving/making phone calls with a Bluetooth headset/headphones. The Bluetooth function works fine for everything else, including pairing with my headset/headphones to watch movies or listen to music, and pairing with my car to receive or make phone calls, listen to music, etc.

However, the Bluetooth functionality does not work with phone calls when paired with a headset/headphones.  For example, I have my headphones paired and am listening to music. I receive a phone call, or go to make a phone call, and the Bluetooth automatically switches off. If I hang up/end my call, the Bluetooth then turns on, and automatically picks up the music I was listening to/movie I was watching. 

This occurs regardless of the type of headphones/headset I am wearing (Beats Powerbeats Pro Wireless Earphones, Sprout Harmonic 3.0 Bluetooth Headphones, etc.).

I have reset/restarted my phone multiple times, unpaired and repaired my devices, nothing is working. Please help!

Hi JCkira - I have tried most of the solutions below and nothing has worked still, any other suggestions? I tried turning on audio option on at a time, audio and then calls, then reconnecting, restarting - still nothing...no sound when making calls with either bluetooth device.

I have continued to try the suggestions in this response feed and still am having no sound when making or receiving calls on my bluetooth devices (this happens on multiple bluetooth devices, not just one set of earphones). I switched on "audio" only then "calls" only, restarted the device, disconnected and reconnected...and still nothing. Did anyone have another solution that worked??

In my case it was Windows Phone Link, even though in its device settings the phone not was to  set to not handle calls.

On the Spanish forum they published this solution: https://eu.community.samsung.com/t5/otros-galaxy-s-series/llamadas-en-bluetooth-no-se-escuchan/td-p/...
In developer mode, find 'Select Bluetooth SAP Activation'. Select 'Force SAP activation'. By default it is 'Default (no effect)'. It worked for me.

Same problem here! I can listen to music, i can record audio, send audio messages, but when i make a call it just like mutes both incoming and outgoing voice not just normal phone calls, also whatsapp calls have the same problem. Bluetooth appears on. Tried the call and audio options but they are already on. Also tried with 3 different bt headsets and got the same result...

And also i'm using the same bluetooth devices for the last 2 years with no problem. It started 2 days ago...

Bro, thank you so much.  I made an account just to post because this has been driving me insane for a few weeks now.  This fixed it for me in a matter of seconds.

Yes , absolutely the same problem. Tried as well to press on BT headsets button during call manually (on the phone screen) but it just doesn't activate.

I got the same issue on my Z fold 7, tried bluetooth headset, car bluetooth and all possible options. Same bluetooth headset work on other mobile including my S21 ultra. So its the Z fold 7 giving issues. I trasfered data from my previous phone, is it beacuse of that bluetooth calls not working. Tried the developer setting also (Sap ON) still no luck
