Hey there Sabz,

I'm sorry to hear that your new Chromecast with Google TV (HD) is giving you issues! I'd be happy to help you out, since I know troubleshooting screen mirroring is a bit tricky. Here is a list of prerequisite settings that you'll need:


Things to know

  • Cast screen is available on devices that run Android 6.0 or higher.
  • Screen casting via the Google Home app isn't supported on Windows and iOS devices.
  • To start screen casting, Power Saving Mode must be turned off.
    • Power Saving Mode can limit the processing power of Android devices which might affect the performance of the Cast screen feature.
  • You must allow Google Cast to use their network information.


Google Nest and Home speakers or displays and Chromecast devices might not be discoverable for mobile devices on Android 12.

During setup, your mobile device might ask them to "Allow Google Cast to use your network information."

Go to Settings and then Use network information Onand then Continue

You also have the option to select Not now, but if you select this option, you can’t continue with setup.


 Important: The Microphone permission in the Google Play Services app needs to be turned on to successfully use the Cast screen or audio feature with Chromecast. If you don't have this permission turned on, the Cast screen session immediately disconnects after it attempts to connect. 

To turn on Microphone permissions:

  1. On the Android device, tap Settings .
  2. Scroll down and tap Apps and then Google Play Services and then Permissions.
  3. Look for Microphone and slide the slider on On.

I look forward to your response, and if you have any other questions or concerns for me, please let me know!

Best regards,
