Troubleshooting Tips When Chromecasting Your Screen

• If the Cast tile is missing on Android, restart your phone and confirm both devices are on the 2.4 GHz or 5 GHz Wi-Fi band.
• Black screen on the TV usually means the app you are using blocks mirroring; try opening a different app or enabling developer options to force screen recording permission.
• Audio not playing through the TV? Disconnect and reconnect the cast session, or check that media volume is not muted on your source device.
• Lag or stuttering improves when you move the phone closer to the router and close background apps that consume bandwidth.
