Credit: Rita El Khoury / Android AuthorityGemini has been available in preview on existing Google Home and Nest speakers and displays for a while now, but as my colleague Rita put it, it is slow, unpredictable, and a painful experience. Every question takes longer to answer, and every answer is unpredictable. Users have been complaining about these issues since the beginning of the preview, and while Google has taken note of the feedback and rolled out changes, some people do want to go back to the older Gemini-free experience. Here’s how you can roll back from Gemini to Google Assistant on your Google Home and Nest speakers and displays with a little bit of work.To be fair, many users are enjoying Gemini on their Google Home devices, but many aren’t. It’s very easy to opt into the Gemini preview, but pulling out of the program isn’t a simple switch. You actually cannot revert Gemini back to the legacy Google Assistant once you opt in and receive the upgrade in your Home.
