If you're near your Google Nest or Home device and Pixel Tablet or phone, only one of the devices should respond to 'Hey Google'. Multiple devices might activate, but only one should respond.
Google chooses the best device to respond to based on various factors like proximity of the device, type of request and capabilities of the device, among others.
Step 1: Update your Google app version
- Open your phone or tablet's Google app
.
- Tap your profile
Settings
- Check the version number.
- If your version is below 6.5, go to the Google app page
.
Settings 
Step 2: Add the same account to all devices
If you have multiple Google Accounts, add the account that you used to set up Google Home on your device.
Important: If the device that responds isn't yours, these steps won't fix the issue.
Step 1: Check which account you use on Google Home
- Open the Google Home app

Step 2: Add the account to your device
