I too am having problems connecting to the BlueTooth Audio from the S24 to my Mazada 3. The phone bluetooth connects, but the audio does not automatically connect as it used to in UI 7. Every time I start the car I have to start the audio playing on the cellphone (if the audio is not playing the bluetooth will never connect for audio. This used to work in UI 7 whether the audio was playing or not), then on the S24, go to bluetooth, go to the device (Mazda), select details and wait to see if it will connect to the audio. If it takes too long and the Mazada stops scanning, I have to turn off the car and try again. It seems like all my other bluetooth devices are working, but none connecting automatically. Something in UI 8 broke this function.
I have tried deleting the devices, re-pairing, resetting the networks, clearing cache, starting in safe mode, and I can't remember every thing else I've tried, but no go.
SAMSUNG, PLEASE FIX THIS!!! Better yet, give us a way to roll back the UI to a previous version that worked.
Once this is fixed, and everything is working, you can bet I'll be turning off automatic updates. Just like I have my computers setup to absolutely NO auto updates.
One last thing. I refuse to factory reset my phone over something like this, so please do not recommend that option. Fix the problem and send out a patch or a new UI.
After almost two days of troubleshooting this is what I found for my situation. October 08, 2025
Hi,
I found that by going to Bluetooth, viewing the Bluetooth devices, and going to detail view for the car connection, the phone connection is turned on, but the audio is turned off. When I turn it on, it immediately turns off again. I turn it back on, and it immediately turns off. I have to do that 3 or 4 times before it stays on. However, by the time I win the on/off battle, the Bluetooth scan that the car is doing times out and I have to turn off the key and restart the car to get the Bluetooth scan to work again. The only way I can get it to work, somewhat consistently, is to have the audio playing on the phone, then start the engine, set the car radio control to Auxiliary, and while the car is scanning for a Bluetooth connection I have to quickly go the Bluetooth settings, details for the device and then turn the audio on, it turns itself on, I turn it back on, it turns itself off, I turn it back on and usually the third time I turn it back on, the audio connects. I have to do this every time I start the car. It no longer connects automatically. I have a 2010 Mazda 3, so that's long before Android was built into the cars. Bluetooth is an auxiliary function of the car's audio system. It's just simple Bluetooth that use to work great, and now it doesn't. Shame on you Samsung!!!
UI 8 broke this functionality and I or we have not heard a peep from you about a fix. Everything worked fine when using UI 7.
2023 X3 my bluetooth was syncing perfectly with android auto etc. Now I can't even find where to pair the bluetooth. I'm so upset, where I live hands free is the only way. Its illegal to hold your phone while driving I'm by no means a techie. I am a frustrated person.
2010 Mazda 3, haven't been able to connect audio on Bluetooth for MONTHS. Only works by toggling the audio button repeatedly as suggested in the Bluetooth settings.
However the entire connection also cuts out every 30 seconds to 10 minutes, so I can't maintain a connection for the average drive, and it's illegal for me to touch the phone at any point while driving. This is really, really frustrating.
I've been going back and forth with Samsung via error reports for months trying to solve this issue, and I can genuinely say it is the most frustrating customer service experience I've ever encountered.
They constantly tell me to try things that I have told them I have already tried with no success. I've sent heaps of error reports with no sign of any advancement.
They even tried to tell me that it was my car that was at fault. Really? As soon as I do a software update, I encounter the same problem that many others are having after the same update? Not buying it.
It is extremely disappointing and frustrating that Samsung have made no effort to fix this problem. It makes me want to switch to an iPhone.
