Step 1. Get started
Casting your Android screen is available on devices running Android 5.0 or higher.
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.

-On your Android device, tap Settings.
-Scroll down and tap Apps and then Google Play Services and then Permissions.
-Look for 'Microphone' and slide the slider On.

-Tap the device for which you want to cast your screen.
-Tap Cast my screen and then Cast screen.
