Google Home today is rolling out the latest updates to Gemini for Home and the mobile app (July 23, 2026), while there’s also new Nest Cam firmware.

On the voice assistant front, Google has expanded the conversational memory that allows you to ask a follow-up without repeating the original command or context. The window “across the entire Gemini for Home experience is now 15 minutes.” This lets you say: 

”Hey Google, turn on the kitchen lights.” … then a few minutes later say, “Hey Google, dim it to 50%.”

The other update brings Gemini Live to the first-generation Google Home Mini and Nest Hub. Say “Hey Google, let’s chat” to start the back-and-forth conversational experience. It’s already available for the Nest Mini, Nest Audio, Nest Hub, Nest Hub Max, and Google Home Speaker.

Meanwhile, Google Home 4.22 for Android and iOS brings automation and smart lock updates:

Automation

• Clearer automation saving guidance: We’ve added helpful alerts when saving automations with conditions but no starters, helping ensure your automations run successfully as expected.
• Expanded window covering controls: We’ve updated controls and labels for smart blinds and window coverings, making it simpler to set precise shade positions.

Smart Locks

• Clearer security action disclaimers: We’ve added reminders that if you remove a member or leave a home to clarify that smart lock passcodes for those users need to be manually changed or removed.

In terms of bug, performance, and reliability fixes:

• Enhanced iOS Video Experience: We’ve lowered playback error rates and improved stream availability closer to real-time on iOS Google Home App.
• Seamless video playback resuming: We’ve fixed an issue where video feeds that had been in progress failed to resume properly after unlocking your phone.
• Improved app link navigation: We’ve fixed deep link navigation so opening device setup or settings links brings you directly to the correct screen.
• Fixed missing battery alerts: We’ve corrected an issue where full camera batteries were incorrectly reported as having zero hours remaining.

Google is also gradually rolling out a Nest Camera July 2026 Software Update for the Nest Cam Indoor (wired, 3rd gen), Nest Cam Outdoor (wired, 2nd gen), and Nest Doorbell (wired, 3rd gen). 

• More reliable connectivity: Improvements to help  cameras stay online with fewer unexpected drops or crashes.
• Smoother setup: Under-the-hood updates deliver a more reliable, consistent, and faster setup flow when adding new cameras to your home.
• Accurate Activity Zones: Fixed person and familiar face alerts  triggering inside ignored zones.
• Improved app reliability: Fixed issues where the app might freeze or display the incorrect camera online status.
• Camera settings: Fixed issues where camera settings were not applied when changed in the app.
