Google tests v3.79 on legacy speakers, boosting audio, Wi-Fi and smart home controls

Google is currently testing firmware version 3.79.550760 for several older smart speaker models through its Preview Program, according to 9to5Google. The update targets the Google Home, Home Mini, Nest Mini and Nest Audio devices. It introduces changes to audio performance, connectivity and smart home control features.

What devices are included in this update?

The testing wave covers the Google Home released in 2016, the Home Mini from 2017, the Nest Mini from 2019 and the Nest Audio from 2020. According to TechRadar, the Google Home Max and the newer Google Home Speaker are not part of this specific rollout. The latter device launched recently and may already include these improvements, while the Max has been running older firmware for some time now.

What changes does the firmware introduce?

Version 3.79.550760 delivers improvements listed by 9to5Google. These include enhancements to audio and media streaming, volume adjustments and setup connectivity fixes for Wi-Fi issues. The update also addresses overall performance stability and smart home control functions. Additionally, it improves the Google Assistant entry experience, which is likely related to Gemini integration.

How can users access the preview build?

Users must enroll in the Google Home Preview Program to receive this update early. According to 9to5Google, participants can sign up via the Google Home app by navigating to the device page, selecting settings, then device information and finally the Preview program option. Updates are applied automatically overnight. A production release for all users is expected in a few weeks.

What comes next for this firmware?

Google has not announced an exact release date for the production channel. According to 9to5Google, it should take a few weeks before the 3.79 update is released to all users. Until then, only those enrolled in the Preview Program will receive the changes. The company continues to operate the Preview Program for speaker firmware testing.

Questions to ask your suppliers

Check whether the vendor provides a timeline for production releases of preview features. Ask if the update changes how devices authenticate with local networks or cloud services. Determine if there is a rollback plan if the firmware causes instability. Inform your network operations team about potential changes to device connectivity patterns. Ensure your asset management records reflect which devices are receiving these updates. Verify that any smart home integrations dependent on these speakers remain functional after the change.

What to do and how to stay safe: Google

• Audit your inventory to identify which Google Home or Nest devices are currently in use.
• Monitor the Google Home Preview Program page for official release notes and known issues.
• Test the firmware on a single device before rolling it out to a larger group.
• Verify that Wi-Fi connectivity and audio streams function correctly after the update.
