Background
For the last several months, Google has been rolling out Gemini to Android Auto (AA). The AI upgrade has received mixed reviews since the rollout began. Some users who preferred the older Google Assistant have now encountered a bug that swaps Gemini back to Assistant.
User Reports
- Multiple users on Reddit have reported that Gemini suddenly disappears and is replaced by Google Assistant.
- One of our writers has also experienced this issue. While some users cannot switch back, others say the problem is temporary.
- On the Android Auto community forums (via PiunikaWeb), a user noted that Gemini worked fine until updating to AA version 16.7; after the update, the system reverted to Google Assistant. Clearing caches, toggling digital assistant settings, and restarting devices did not resolve the issue.
- Another user reported encountering the bug on version 16.6.661414, suggesting the problem may not be limited to a single version.
Official Response
A Google community specialist replied:
