Galaxy A7 bluetooth connection error after update HFP connection lost

Apprentice

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, as usually the users come from different regions therefore could you share your region, provider and the safety level of your installed update, please?

I got the One UI2 Android 10 update in the Netherlands and it looks like the issue has been solved. I had to check for updates manually to install the new version.

Since then I didn't see disconnects, but because of the Corona Crisis I do not use my car so often.

Hi.  I am in the UK and following the recent UI software update my bluetooth connection to my car is working perfectly.  This just proves that it was a software fault caused by Samsung!  They insisted the fault was with my car and that I should get it checked out at the dealership!  I told Samsung on 8 separate occasions that it was a fault with the Samsung software update in January.  They repeatedly refused to concede this fact and I spent many hours pairing/unpairing, clearing the bluetooth cache etc.  What a waste of my time!!

 

I hope you have all had the latest update and your bluetooth connection is also working now.  Stay safe people.

I have similar problem with ATOTO.  They requested to turn off "HD audio: Qualcomm aptX audio" option on your phone. However, unfortunatelly Galaxy A7 has this function.
