Hi guys, (I fixed it, read and let me know)
I see you are struggling with this issue. It happened to me since 3 days ... right after the last update of my phone.
This is my set up : - Galaxy note 9 with updated android pie 9.0 (before 8.1 oreo)
- Jaguar XE 2016
So right after the update I noticed that the bluetooth connexion in my car was lost all the time which was a pain in the *** of course.
I searched google and fall here, I went through all 23 pages and tried it all omg anyway nothing worked except one thing : Downgrade to oreo 8.1
For me downgrading was maybe something insanely hard to do and I refused to do it, it was a solution given in the very few first pages here.
Anyway, hopeless, I gave it a try and I made the downgrading and it was very easy.
First of all (VERY IMPORTANT) make a back up of your phone cause this procedure will remove everything on it, you will start from scratch there is even a factory reset at the end !!
For back up : I used samsung smart switch on my computer it was very easy, just few hours of time needed. in less than 3 hours my phone is back to oreo 8.1 and I got all my datas back like nothing happened.
AND IT F***** WORK BACK ON MY CAR !!
It's quite easy to do, and the software needed to download are safe, I used it myself.
So if you guys give it a try, let me know if it works for you.
