Hello,
my Samsung Galaxy A7 (2018) bluetooth can not connect anymore or just for 10 seconds to my car ("HFP connection lost, Blutooth Audio connection lost") than dropps the connection again and again after the latest software update (A750FNXXU3BSKB). There was no any bluetooth connection issue with the previous version. Nor all of the listed trouble shooting steps nor finally the factory reset could not solve the problem. Can anyone help, please?

Hello, last 3 update (dec, jan, febr) could not fix the issue, you can go back to 01.nov.2019 firmware, it is the last working firmware.

I have found a workaround to fix this temporarely , till Samsung releases a patch for fixing it.
Well , when Mobile phone is trying to connect to the car bluetooth device , that time do a call using the mobile phone.
When call established and you are talking to the one you have called , after 10 sec the connection will be established with the car audio system and then it will stay connected. But , as been said, the connection is valid till the next time you will switch off the car and break the connection. So every time I get into the car , I do a fake phone call to a number and wait till the connection is established. Try it

I think it relates to the smart lock of the screen, it seems that if the screen is active, Bluetooth connectivity is fine.
