Another problem with my S21 FE, Bluetooth calling

[AndrewMiller573]

Have found recently another problem that i have tried to fix in numerous different ways, when using Bluetooth for calling i cannot hear anything and the person on the other side cannot hear me, i have tried calling in safe mode using Bluetooth and no luck after using a few different developer options to do with Bluetooth still nothing will work, problem occurring on a S21 FE, this is getting annoying because this is not the first problem im having a problem with this phone having a problem with WiFi not working, check my other post for details on it.

@AndrewMiller573: If you have a Bluetooth headset connected to your Galaxy S21 FE, then please head to Settings > Connections > Bluetooth > On > Tap the cog symbol to the right of your headphones > Toggle on 'Calls' from here. If you have a set of Galaxy Buds then you can double tap the touchpad to answer an incoming call. For call audio issues, try pressing and holding the Volume Up button to increase the overall call volume. If the caller can't hear you, then please confirm the model name/number of your Bluetooth headset, so we can explore further troubleshooting steps.

If WiFi calling not working speak to your network provider

I have the same problem, with multiple functioning headphones, and this does not solve it. I've restarted and reconnected. Any suggestions?
