Android Auto Broken After One UI 9? Google Says the Fix Is Rolling Out Now

If your Galaxy phone stopped talking to your car after the One UI 9 update, the problem wasn’t your cable or your car. Google has confirmed that Android Auto connection failures on Samsung phones running One UI 9 are real, and that a fix is already rolling out.

Google told 9to5Google on November 3 that “a fix has been rolled out.” It also told Android Authority that affected users “should see the issue resolved soon.” Below: what went wrong, who was affected, and what you can do while the fix reaches your phone.

What broke after One UI 9

One UI 9 is Samsung’s Android 17 update, and it is now reaching more Galaxy phones in the U.S. Some owners who installed it found that Android Auto started acting up. The reported symptoms:

• Android Auto won’t launch on the car’s screen at all.
• It connects, then drops, sometimes repeatedly and sometimes in the middle of a drive.
• Stuttering, laggy performance while it is connected.

The failures happened over both wired USB and wireless connections, so switching from one to the other didn’t help. According to autoevolution, users also tried the usual fixes, including clearing the app cache, reinstalling Android Auto and updating to the latest version, without luck. Many said the same cable had worked fine on One UI 8.5.

Which Galaxy phones were hit

Reports came from Reddit, Samsung’s community forums and Google’s support forums. Phones named in those threads include the Galaxy S24 Ultra, Galaxy A55 5G and Galaxy S26. Android Authority reproduced the problem on an S24 Ultra running One UI 9, while a Galaxy S25 Edge still on One UI 8.5 connected normally. That was an informal test on two different phones, but it pointed to the update.

9to5Google described the problem as not “massively widespread” but with “a clear pattern.” If you drive with Android Auto every day, that is little comfort. A dead dashboard means no Maps, no podcasts and no hands-free texting.

How the fix reaches your phone

Sources disagree on this part. Google has said only that a fix is rolling out. It hasn’t said publicly whether that means an Android Auto app update, a Google Play services change or a server-side switch.

• Autoevolution reports that the fix arrives with Android Auto 18.1, which started rolling out on the Play Store this week.
• Germany’s Netzwelt describes it as a server-side patch delivered in the background through Google’s services, with no Samsung firmware update needed.
• Gadget Hacks notes that Google hasn’t named a delivery method, version number or completion date.

Google’s own statements are the most reliable source, and they don’t name a version. Either way, you don’t need to wait for Samsung. Keeping Android Auto and Google Play services up to date covers both possibilities.

What to do right now

Try these in order. Most people should be fine after step 3.

1. Update Android Auto. Open the Play Store, search for Android Auto and tap Update if it’s offered. If you can get version 18.1 or later, install it.
2. Update Google Play services. Go to Settings > Apps > Google Play services > App details in store and update it if a newer version is waiting. Also check Settings > Security and privacy > Updates for a pending Google Play system update.
3. Restart the phone, then reconnect to your car.
4. Re-pair the car. On wireless, forget the car in Bluetooth settings and remove it under Android Auto’s previously connected cars, then pair again from scratch.
5. Clear Android Auto’s cache. Go to Settings > Apps > Android Auto > Storage > Clear cache. Leave Clear data for last, since it wipes your Android Auto settings.
6. Check for a Samsung update under Settings > Software update. Google isn’t relying on one, but a later One UI 9 patch won’t hurt.

Skip the factory reset, and don’t buy a new USB cable or book a dealer visit yet. This is a software problem on Google’s and Samsung’s side, and the fix is already rolling out.

If none of that works, the fix probably hasn’t reached your phone yet. Google rolls updates out gradually, and Play Store releases can take a week or more to reach everyone. Give it a few days. If Android Auto is still failing after a week, report it in the Android Auto app (Settings > Help & feedback) so your device model reaches Google’s team.

The bigger picture for Galaxy owners

This is the third notable One UI 9 problem in about two weeks, after a battery-drain complaint on the Galaxy S24 and S25 and a setup bug on the Galaxy S26 Ultra. Big Android version jumps always shake out bugs, and Google moved fast on this one. Still, it’s a good argument for waiting a week or two before installing a major update, especially if your car relies on your phone.

There’s better news ahead. Google is preparing its first major Android Auto redesign since Coolwalk in 2023, a project reported under the name “Cielo,” with widgets, support for more screen sizes and new video and browser app categories. Autoevolution expects testing to start around the end of the year. Google hasn’t announced a timeline.
