Overview
- Preview Program firmware version 3.77.500695 makes Nest Mini and Nest Audio cycle blue, red, yellow, and green after “Hey Google” before returning to white.
- The update is rolling out through the Google Home app’s Preview Program, with the current stable firmware remaining at 3.76.495998.
- The effect is most noticeable on Chalk and Charcoal finishes and is less visible on Coral units.
- The same preview build is also appearing on older Google Home and Home Mini speakers, according to reporting.
- The visual change arrives ahead of Gemini for Home early access expected in the U.S. on October 28, and some users report subtle shifts in voice responses and behavior.
