How to Cast your Android screen from the Google Home app ?

Casting your Android screen lets you mirror your Android device to the TV so you can enjoy your content exactly as you see it on your mobile device—only bigger.

For a video demonstration, check out the YouTube video at the bottom of this article. If you prefer step-by-step instructions, see below.

Step 1. Get started 

• Casting your Android screen is available on devices running Android 4.4.2 or higher. Please note: Some devices have been optimized for screen casting so your experience may vary.
• Casting your Android screen is not supported on iOS or Windows devices.
• Turn off "Power Saving Mode" on your Android device. Power Saving Mode can limit the processing power of your device which might affect the performance of the Cast Screen feature.
• Important: The "Microphone" permission in the Google Play Services app needs to be turned on to successfully use the 'Cast Screen/Audio' feature with Chromecast. If you don't have this permission turned on,  the Cast Screen session will immediately disconnect after trying to connect. 
  • To turn on microphone permissions:
    1. On your Android device, tap Settings  .
    2. Scroll down and tap Apps  Google Play Services  Permissions.
    3. Look for "Microphone" and slide the slider On  .
