Android 11 requirement stops old phones
Google disabled Android Auto access for smartphones running Android 10 or older, requiring Android 11 or higher as the minimum operating system version, mobzine.ro reported.
The software block took effect in November 2026, leaving older devices unable to connect to vehicle multimedia systems.
Older models lose Android Auto functionality
The update blocks popular older models that no longer receive official software updates from manufacturers. Devices affected by the requirement include the Samsung Galaxy S9, Galaxy Note 9, and Sony Xperia XZ2 Compact, according to ziare.com. These phones reached their maximum official firmware at Android 10.
Users first received warnings about the upcoming compatibility drop in October, as noted by Zona IT. While affected phones still handle calls and basic apps locally, owners can no longer mirror Google Maps or media apps onto car dashboard displays through Android Auto.

Historical requirement updates by Google
Google adjusts the platform requirements periodically as older operating system usage declines across the active user base. In 2022, the company blocked devices running Android 6, followed by Android 8 devices in 2024, mobzine.ro reported.
Most users encountered the sudden loss of connectivity following a routine Google Play services update. Some devices running Android 10 briefly retained functionality with newer service packages while displaying expiration notifications.

Samsung One UI 9 update complications
Driver reports on Reddit, official Samsung forums, and Google support pages describe intermittent freezing and audio stuttering.
One UI 9 updates cause performance issues
Samsung continues distributing its Android 17-based One UI 9 update globally to an increasing number of models. An interesting example was highlighted by the publication Android Authority, where a test conducted by a user showed that a Galaxy S25 Edge running One UI 8.5 operated without issues, while a Galaxy S24 Ultra updated to One UI 9 immediately exhibited difficulties similar to those reported online.
This comparison does not confirm the cause, but Android Auto support cannot improve the in-car multimedia experience if your phone does not run at least Android 11, though users can still use Google Maps or Waze.

Potential workarounds and community modifications
In some cases, it might be possible to upgrade your device to Android 11 by turning to the Android Modding community. If your phone is popular enough, there is a chance you will find a Custom ROM version based on an Android kernel slightly newer than the last one supported by the device manufacturer, though it is good to know that not all of them offer Android Auto compatibility.
Gemini and Android Auto face bug complaints
What seems similar to recent complaints in the US is when Gemini refused to call 911 or pretended to be calling. Google promotes Android Auto as an advanced competitor to Apple CarPlay, but it is so full of bugs that one observer stated they are surprised it can work at all.
