Car Stereo Bluetooth Issue Remains

[CrymsonDawn]

I reported this in every iteration of the beta for the S25+ and the issue has persisted into the stable release. 

UI8 has a bug where Bluetooth connection to non-Android Auto vehicle stereo systems that use only Bluetooth is not functioning properly. 

Auto connection never works and, on the occasions where it is able to connect after manual toggling, both audio and phone connections are prone to constant disconnecting. 

This seems to be an issue on most non-Android Auto Bluetooth car stereos and is not limited to just Samsung devices, with Android 16 at large having this issue based on reports from Pixel users.

Despite months of reports from Android users of many manufacturers, this issue has persisted.

Could you explain the bug a little further because I have a old infotainment system with an s25 Ultra and the only problems I have had are with Android auto itself which has always been quite garbage and in fact have been needing to use my regular infotainment systems Bluetooth over the Android auto.... also in many cases the problem isn't actually the Bluetooth or your infotainment system it's actually Wi-Fi as the infotainment systems only connect the Bluetooth for basic functions but everything else is literally ran through Wi-Fi and that honestly has seems to be the issue but unfortunately there is nothing that Google or Samsung can do about that Wi-Fi is becoming an old source of material anyway in favor of NFC and newer technology it's kind of fading out as well as regular standard Bluetooth Stacks that we currently use if you're having an issue the only thing I can suggest is hardwiring for a while unless you give them much more detailed explanation on what's going on and I may be able to help you as this is what I do for a living

Like I said, this is about non Android Auto systems that connect solely through Bluetooth.
The Auto connect function has ceased to work when it worked flawlessly pre update and disconnects constantly even when manually toggled to connect.

Usually phone calls might connect sometimes but audio will never work.

Any system with Wi-Fi seems to work fine

Could just be a flaw in that update that they'll fix in another system update other than that I'm not sure if it has nothing to do with Android auto itself or any Android infotainment systems unfortunately I've never used a non Android infotainment system before no car I ever purchased had one standard I've always used aftermarket the only thing I can suggest is maybe do a full system cash reset and try that if you don't know how to do that I can walk you through it

Already tried by myself and hundreds of others. It's definitely some issue baked into Android 16 itself that has yet to be solved and like I said, it's not relevant to Android Auto

[Zero_83]

Could very well be it seems like with every new Android update there's always some sort of a bug or an issue are you using the full or the beta?

Thanks for highlighting this. It looks like a broader Android 16 bug affecting Bluetooth connections with non-Android Auto car stereos, not just Samsung devices. Since it’s been reported across multiple brands and persists from beta to stable, the fix likely needs to come from Google in a future Android update. In the meantime, reporting through Samsung Members and the Android Issue Tracker can help keep pressure on for a resolution.

If it's an Android 16 issue and not a Samsung one, you should be reporting it to Google. If it was only happening with Samsung phones, then reporting it to Samsung would influence Samsung to work with Google on a fix. Since it's across multiple brands, it's a Google issue alone.

Im now dealing with this after the UI8 update

I'm sorry. Samsung has yet to address this issue publicly despite constant reporting, it's really disappointing.

I've figured out that if you try to manually toggle the audio switch in the Samsung Bluetooth menu while already playing music on your phone, it will connect on the 3rd or 4th try.

It doesn't connect if music is not playing already
