Wi-Fi Display (Miracast) Receiver is a useful application that allows you to use your Android device as a Wi-Fi display. This means that you can use it to mirror the screen of your phone or tablet to a TV or other compatible devices.

To start, open the application, select your Wi-Fi network, and then click on the "Start" button.

This will create a network connection, and then you can select the Wi-Fi network you want to mirror.

You can now start using the application. To do so, select your screen and click on the "Mirror" button.
