Google Rolls Out Fix for Android Auto Problems on Samsung One UI 9 Phones

Overview

• Samsung began a wider rollout of One UI 9, and users soon reported Android Auto stuttering or failing to connect on several recent Galaxy models.
• Affected owners described two main symptoms: audio and display stuttering after connection and complete failure to establish Android Auto links with car head units.
• A limited test by Android Authority reproduced the issue on a Galaxy S24 Ultra running One UI 9 while a Galaxy S25 Edge on One UI 8.5 did not show problems, suggesting the OS update may be the trigger.
• Google has confirmed it deployed a fix to address the problem, though the company did not say whether the change comes from an app update or a server-side adjustment and has not listed a version number.
• If problems persist, users should check for system and app updates, restart the phone, clear Android Auto cache, try a different USB cable or wireless setting, and report remaining cases through Android Auto feedback so vendors can track unresolved pairings.
