To realize screen projection, you need to pay attention to the following points to ensure that both the mobile phone and the TV or screen projection device support the screen projection function and are connected to the same wireless network. Open the video on Mango TV mobile phone, and check whether there is a screen projection icon after entering full screen mode. If the icon is displayed and you can search for devices, you can use the screen projection function. Due to copyright protection, some video content may not support screen projection. If this happens, you can try other methods, such as mobile phone mirror projection. There may be a bug in the operation of the equipment, which leads to the failure of the screen projection function.
