After one ui 8 my car will no longer hold a connection via Bluetooth. (2010 Mazda 3) I've had this car for 15 years, never had a connection issue until now. My phone works with my work vehicle and my friends iPhone 13 has no issues with my Mazda. I can't figure out the conflict! I've tried removing the device and starting fresh, but nope. The weird part is my phone connection will connect, stay connected, but the audio toggle for music won't stay connected and takes multiple times to connect. If it does connect, after i turn off my car, it won't reconnect like before one ui 8. It always connected the 1st time and always connected if i turned my car off and on again. Sorry for the rant, but it's driving me crazy.

In the Playstore Store you can do this.

I can't post links here but search for the android Auto community and there will be "experts" there that can escalate to the android team

You will have to wait for Google to issue a Play System update unfortunately. Ui8 is still on July, every other device I am on is September.

Does anyone know how to S25 to connect to Android auto. Samsung is no help and states there is no problem on their end. Funny, my S20 works just perfect but not the S25.

I try all ideas on the internet for help nothing works.

Thanks

Saying you've tried "all ideas on the internet" doesn't tell us anything. Do you want to use AA via wired or wireless connection? If wireless, are you using a BT dongle or does the vehicle have wireless AA? Which vehicle do you have?

There is a different procedure for connecting to AA on newer devices than there was on the S20. For one thing, AA is no longer a separate app. Look in settings/connected devices for Android Auto and configure it for your vehicle and preferences.

We ran into issues with AA as well and it acting like it would connect but not actually functioning. We were using wired AA. Turns out the cable was old and needed replacing.

I would suggest going wireless if you can though. So much nicer and easier. No worrying about cables. They sell dongles to convert wired to wireless. Probably the best one out there is the Motorola one.

That's the same one I use. Not a single problem in the 3 years I've had it.

My S25 ultra keeps disconnecting from my car bluetooth randomly mostly with my audio and I would have to manually reconnect it and sometimes it still won't connect for the next couple minutes. If anyone knows of how to fix this please let me know.
