Hi @Samsungers ,
happy to help you get this sorted. Google has made changes on their devices and software, meaning that this is no longer compatible with Smart View on Android 12. However, you can still connect your phone to your TV using the Google Home app.
Thanks for letting me know @Samsungers . Is your phone data turned on when that happens? If so, turn your phone's mobile data off and start the process over. When your phone connects to the device's wifi temporarily, it thinks that there's no internet connection and switches to mobile data — turning it off will prevent it from happening.
If this is not the case, I would recommend resetting the Chromecast: While the Chromecast is plugged into the TV and powered on, press and hold the button on the back of the Chromecast. The LED will start blinking yellow. When the LED light turns solid white, release the button and the Chromecast will then reset.
I manage to connect when I share my wifi hotspot, but once my S22 ultra connects to mobile data, by chromecast cannot connect to wifi! Hotspot credential remain the same. Pls help.
I have the exact same issue. My chromecast will not connect to my S22 Ultra hotspot once this is on mobile data. That means my Chromecast is unusable when not at home.
Samsung should provide assistance to this.
