Samsung One UI 7 Update Breaks Wireless Android Auto: What You Need to Know and How to Fix It
Samsung’s One UI 7 update, which is based on Android 15, appears to be causing issues with Android Auto connectivity. Following the update, several users have reported that Android Auto either fails to connect entirely or becomes unstable during use. Here’s what you need to know and how to possibly fix it and report it to Google or Samsung.
The problem seems to have emerged after installing the latest firmware, suggesting that something within the One UI 7 or Android 15 software layer may be interfering with Android Auto’s ability to function correctly. This disruption is affecting both wireless and wired connections in some cases, leaving users unable to use key features like navigation, music playback, or messaging through their car displays.
Samsung and Google have yet to officially acknowledge the issue directly, but affected users are hoping for a swift fix in an upcoming patch or software update.
The highly anticipated One UI 7 update for Samsung devices, especially the Galaxy 2021-2024 launched devices are facing severe issues with Android 15. Android Auto users have reported widespread issues connecting their phones to wireless Android Auto systems post-update. From after market dongles like the Motorola MA1 and AAWireless to premium in-car infotainment systems like the Toyota Yaris Cross (model 2023), OPEL CORSA 2023, BMW X1 U11, 2023 Infiniti Q50 Luxe, and more things have suddenly stopped working.
Some Google Pixel devices running Android 15 also faced similar issues, but Google recently released Android 16 and things seem to be fine for now. While Samsung is also working on One UI 8 beta program based on Android 16, it will take a while for stable Android 16 to reach Samsung Galaxy phones.
The Problem — Wireless Android Auto Just Stopped Working
After updating to One UI 7, Android Auto community and forum users have raised red flags about losing wireless Android Auto functionality completely. Devices that were previously working flawlessly — like the Car or head unit make & model: BMW X1 U11, Toyota Yaris Cross (model 2023), OPEL CORSA 2023, or Samsung Galaxy S22 Ultra paired with AAWireless 2 or Motorola MA1 dongles — are no longer connecting at all.
Some reported problems include:
- Android Auto stopped working after updating to Android 15
- Wireless Android Auto won’t connect.
- Bluetooth auto-pairing fails in vehicles like the Infiniti Q50.
- In some cases, even wired Android Auto fails to initiate.
- Attempts to reset connections and re-pair devices show no improvement.
- The problem appears widespread, impacting various devices and car models.
Why One UI 7 Might Be to Blame
The One UI 7 update is based on Android 15, which brings underlying rework of connectivity frameworks, permissions, and background services. While these changes are meant to enhance security and stability, they can disrupt compatibility with third-party accessories and vehicle systems that rely on these things.
Something to note here is that Samsung’s One UI 7 firmware always had some underlying issues, and thus, was delayed for almost a year. It’s only now that Samsung has released stable One UI 7, while simultaneously developing One UI 8 internally.
With updates like One UI 7, any misalignment between the OS and the Android Auto app can break these interactions.
