What happened
After Samsung rolled out the One UI 9 software update, a number of Galaxy users began experiencing a failure of Android Auto to stay connected to their car displays. The problem manifests as an inability to pair the phone with the head‑unit, or an abrupt loss of the wireless link during use. The issue was first noted on community forums and social media, and has since been reported across multiple device models.
Details of the problem
According to reports collected by Sammy Fans, the malfunction appeared only after the upgrade to One UI 9, which runs on Android 17. Users who had previously used Android Auto without trouble found that the feature either refused to pair or disconnected without warning. Attempts to resolve the issue—including clearing the Android Auto app data, re‑pairing the phone, and switching to a wired connection—did not succeed for at least one Galaxy S26 owner.
Another contributor highlighted a direct comparison: two Samsung phones still running One UI 8.5 paired with Android Auto flawlessly, while a Galaxy S24 Ultra that had been updated to One UI 9 exhibited the same connectivity failure. The problem is not limited to a single flagship; complaints have been logged for the Galaxy S26, Galaxy S24 Ultra, Galaxy S25 Edge, and even mid‑range models such as the Galaxy A55 and Galaxy A34.

Reddit threads, Samsung Community posts, and the Android Auto support forum have all featured similar accounts. Some users noted that the issue mirrors earlier complaints about wireless Android Auto dropping connections, a problem that Android Authority documented before the One UI 9 rollout.
Background on Android Auto and One UI 9
Android Auto is Google’s platform that mirrors phone apps, navigation, and media onto a car’s infotainment screen, supporting both wired and wireless connections. Samsung’s One UI is the manufacturer‑specific skin that sits atop Android, and the recent One UI 9 update brings Android 17 to a wide range of Galaxy devices. The update has been gradually expanded to include tablets and mid‑range phones, following earlier releases that caused occasional glitches, such as a freeze on the error screen for some models.
Google confirmed to a user with a Galaxy A55 that the complaint had been forwarded to its Android Auto team for further review. However, neither Google nor Samsung has released an official statement identifying the root cause or a timeline for a fix.
What it means for users
At present, affected owners have no definitive remedy. The standard troubleshooting steps—clearing app data, re‑pairing, and switching to a cable—have not restored functionality in the documented cases. As a result, many users are forced to revert to older software versions where possible, or to wait for a future patch from either Google or Samsung.
The situation underscores the interdependence of Android Auto and the underlying operating system. A change in the OS layer can inadvertently disrupt the communication protocols that Android Auto relies on, especially for wireless pairing. Until the companies coordinate a fix, drivers who depend on Android Auto for navigation and hands‑free operation may need to use alternative methods, such as a direct USB connection (if supported) or a different smartphone platform.
Outlook
Both Google and Samsung have acknowledged the reports, but no concrete resolution date has been announced. The issue is being tracked internally, and a software update that restores Android Auto connectivity is expected to arrive in a future release cycle. In the meantime, users are advised to monitor official Samsung and Android Auto channels for announcements, and to share any additional findings that could help isolate the problem.
