- Turn off the TV.
- Unplug the power cable.

4. Connect Both Devices to the Same Wi-Fi
Your phone and Android TV must be connected to the same Wi-Fi network for Chromecast and most casting technologies to work.
5. Restart Your Wi-Fi Router
Restart the router to refresh network communication between devices.
6. Check Internet Connectivity
Verify that both the TV and phone have a stable internet connection.

9. Update Google Play Services
Ensure Google Play Services on your Android phone are up to date.
10. Update Google Home App
The Google Home app should be updated to the latest version for reliable casting.

Open Google Play Store on the TV and install updates for Chromecast Built-in if available.
12. Turn Wi-Fi Off and On
Disable Wi-Fi on both devices for a few seconds, then reconnect.
13. Disable VPN
VPN connections may prevent Chromecast discovery on the local network.
14. Disable Guest Wi-Fi
Guest networks often block communication between connected devices.
15. Reconnect to Wi-Fi
Forget the Wi-Fi network and reconnect on both devices.
16. Enable Location Permission
Android requires location permission for nearby device discovery used during casting.
17. Check Router Isolation
Disable AP Isolation or Client Isolation if enabled in the router settings.

Move Bluetooth devices away temporarily if wireless interference is suspected.
19. Try Another Casting App
If one application cannot cast, test another app such as YouTube to determine whether the issue is app-specific.

Settings → Apps → Chromecast Built-in → Storage → Clear Cache
21. Reset Network Settings
Reset your Android TV network configuration if persistent connection issues continue.
22. Factory Reset the TV
23. Check Device Compatibility
Some phones support Google Cast, while others rely on Miracast or manufacturer-specific screen sharing features.
