To view your phone's screen, you need to go to the developer menu on your Galaxy smartphone. This is well hidden. To do this, first pull down the quick settings and then long press on the “Smart View” tile.
These steps are now important for transfer:
- Tap the three-dot icon at the top right and open Settings.
- Open the About Smart View menu at the bottom of the screen.
- Quickly tap the part of the screen that says Smart View 10 times.
- When prompted, enter this password: #00rtsp00
- With the Developer Options menu open, enable the Google Cast switch.
You can now turn off Quick Settings, tap Smart View as usual, and view all your Chromecast, Android TV, and Google TV devices. The required developer list will only be available if you repeat the steps above.
If you want to try it first, feel free to type in the password I provided. But be careful: you can do a lot with the developer menu. So it is recommended to test only the screen transfer and not change any other settings.
