## Troubleshooting

<Accordion title="TV not appearing in app">
  Ensure both your phone and TV are connected to the **same Wi-Fi network**. Try restarting the SmartCast app and power-cycling your TV. Also confirm your TV has an active internet connection by checking its network settings.
</Accordion>

<Accordion title="Pairing code not appearing">
  Manually trigger a new pairing code from your TV by navigating to **Menu > SmartCast > Pair Device**. The code will then display on screen for you to enter in the app.
</Accordion>

<Accordion title="Why does the SmartCast app keep disconnecting?">
  Battery optimization settings on your phone may be causing the app to close in the background. Go to your phone's settings and **disable battery optimization** for the VIZIO SmartCast app to maintain a stable connection.
</Accordion>

<Accordion title="Can't cast from phone">
  Casting requires the app to have permission to access your local network. Open your phone's settings, find the SmartCast app under app permissions, and ensure **Local Network** access is enabled.
</Accordion>

<Tip>
  Use voice commands through the SmartCast app — say **"Hey Google"** or **"Alexa"** to control your TV completely hands-free.
