How do I screen-cast Phone (2a) to my TV?

1. To set up screen-casting, swipe down twice from the top of the screen to access the expanded quick settings. Press the edit (pencil) icon and drag the screen cast tile up from the hidden tiles.
2. To begin the screen-cast (mirroring), swipe down to open the quick settings and find the newly added Screen recording tile. Click on it once and select the targeted device to cast to connect in the same local area network.
