Samsung S8 - Bluetooth media audio works but call audio doesn't work

[Android Central Question]

Hi,
I have had an issue for last few months and none of the software update till latest one installed today doesn't resolve the issue.
When I connect my S8 to any Bluetooth device (car Bluetooth system, couple of different Bluetooth headset), media audio works okay always and call audio doesn't work. I can't hear the call audio but on other end can hear me which I reckon mic is working bluetooth call, but bluetooth speak is not working.

I have done everything I have seen in many different forums - clear Bluetooth cache, memory, unpair/ repair, disable "Ok google". Only thing I haven't tried is factory reset, which I know may fix temporarily but issue will come back again after few days.

Very rarely, incoming call works but most of the time it doesn't work. Outgoing call never works. So I have been using mobile's call speaker mode instead of Bluetooth mode which is inconvenient and more so driving me nuts

I have tried previously but still tried deleting cache, data and force stop but still issue occurs when device connected again.

Regarding permission, my setting is set to "No permissions required"

Check in system app bluetooth has the permission on ?



Also all 3 on that list clear data,cache,force stop

I can see you're permissions. But most of my inbuilt aystem apps have got "No permissions required" which I not sure how to change on my Samsung S8 running android 9.0. Other apps that was installed, I am able to control permissions.

Try this setting>apps>3 dots upper right corner tap>reset app preferences
