Galaxy S10 bluetooth constantly reconnecting to Car head unit

I have a Android head unit in my Car on Android Oreo.  I keep having issues with the Bluetooth connection from my S10 in which it disconnects and reconnects over and over every 30 seconds.  Here are results and a work around I found.

 

Galaxy  S4 connection to Head Unit

First pair:   Works fine

Future auto connects:  Works fine

 

Galaxy S9 connection  to Head Unit

First pair:   Works fine

Future auto connects:  Works fine

 

Galaxy S10  to Head Unit

First pair:   Works fine

Future auto connects:  disconnects and reconnects over and over every 30 seconds

 

Galaxy S10  to Head Unit paired using 3rd party app called Force Pair

First pair:   Works fine

Future auto connects:  Works fine

 

I tried everything to get this working since my S10 arrived. 

S10 is on the latest update

Updated my Car Head Unit to the latest Firmware and Software. 

Played with the developer bluetooth settings on the S10. 

Tested pairing from the head unit and the phone separately. 

Tried factory reset on both phone and head unit. 

Tried forgetting all network settings on S10. 

Tried disabling media and ringtone volume sync

Disabled Sleeping Apps, adaptive battery etc

Set All apps to not optimised

Tried unlocking the screen.

 

NON of the above worked.  Only using this 3rd Party app Force Pair works, which has to suggest its a bug in the Bluetooth Connection Pairing.  I dont even seem to need to keep this app running on my S10, just paired with it and the problem is gone.  Samsung support just keeps telling me to take my phone to a repair centre but its not broke, all other bluetooth devices work fine.

 

If your experiencing any issues like this, its possible this workaround will work for you also
