          Note: Not all Android smartphones support the screen mirroring function. For smartphones that support screen mirroring, there are options similar to this in the “Settings” or “More Functions” options of the smartphone, for example: “Screen mirroing”, “Wifi-display”, “multi-screen”, “screen projection”, “play to”, “media output”, etc.

          If the projector’s pre-installed screen mirroring app is not compatible with your Android smartphone, you can also download and install Airscreen, happycast and other apps that support wifi-display on the projector.

Tips：

          Some video apps with copyright protection cannot support wireless projection from other devices to the projector. For example, Netflix, iTunes Movie, Google Movie, Amazon Prime do not support this function on some smartphone and computers. All Android system projectors on the market are the same.
