Android Auto and One UI 9 aren't getting along for some Galaxy owners

Your phone gets a shiny new Android update, but your car suddenly wants nothing to do with it. That’s the frustrating situation some Samsung Galaxy owners are facing after installing One UI 9, with reports of Android Auto refusing to connect or repeatedly dropping connections. The complaints have now caught Google’s attention, although the cause remains a mystery.

The problem isn’t limited to one Galaxy model. In a Samsung Community thread, a Galaxy S26 owner reported that Android Auto stopped working after updating to One UI 9. Re-pairing devices, clearing app data, and switching to a wired connection did nothing. Other Reddit users described similar failures, although some said Android Auto continued working normally.

One particularly revealing report involved a Galaxy S25 Edge owner who tested other Samsung phones running One UI 8.5. Both connected successfully, but updating a Galaxy S24 Ultra to One UI 9 reportedly reproduced the problem.

Meanwhile, Google has responded to a Galaxy A55 user’s complaint, confirming that the Android Auto team received the report and forwarded it internally.

However, that acknowledgment leaves several questions unanswered: We still don’t know whether an investigation is complete, whether these reports represent a known issue, or whether One UI 9 is responsible.

Android Auto has been down this road before. Earlier complaints involved wireless disconnections, including on the Galaxy A55, long before these One UI 9 reports surfaced.

Could this be an old problem resurfacing, or has Samsung’s latest update introduced a fresh headache? We’ve reached out to Google to clarify whether the company is investigating the complaints, if they’re connected to earlier reports, and whether a fix is in the works. We’ll update this article if we hear back.

For now, affected drivers will have to keep troubleshooting a connection that worked before their phones got smarter.
