Enable Samsung screen mirroring on Chromecast and Android TVs

To do so, open Smart View, tap on the three-dot icon in the upper-right corner, tap on Settings and enter the About Smart View menu. Tap 10 times on Smart View and when you are asked for a password, enter #00rtsp00. A developer options menu will open up where you need to enable Google Cast.

Once you go back to the Smart View menu, you will see non-Miracast TVs and Chromecast available for screen mirroring.

The same steps are required to enable the Start SecondScreen feature that allows you to extend your Windows 10 or 11 PC's desktop environment. Windows key + K is the quick shortcut to connect to your Samsung phone.

It's nice to finally get support for this, but hiding the feature in secret menus like that is a disservice to all users. Maybe Samsung is still testing it before providing official support in upcoming versions of One UI.
