Samsung's One UI 9 update, the company's first software release based on Android 17, is causing trouble with Android Auto for owners of Galaxy smartphones. Users report that after installing the update, their phones either cannot connect to the car's infotainment system at all or lose the connection repeatedly while driving.

What users are reporting

The complaints fall into two main groups. In the first, the phone simply fails to establish a connection with the vehicle's multimedia system. In the second, the connection works at first but drops at random during a drive, which interrupts navigation, music or calls routed through the car.

Some users also describe a laggy interface, with Android Auto stuttering and responding slowly. The reports do not point to a single car brand or Galaxy model, and the scale of the problem has not been confirmed.

Why it matters

Android Auto is a daily tool for many drivers, and an unstable connection is more than an inconvenience: it can force people to fiddle with their phone behind the wheel. The issue adds to earlier complaints about problems with the new One UI 9 software.

For anyone who has not yet updated and relies on Android Auto, it may be worth waiting for feedback or a follow-up patch before installing the new version.

Samsung has not yet been cited with an official fix or timeline in the available information. Users affected by the bug will have to wait for a corrective update.
