Android Mirroring Requirements

To mirror your Android device to your computer using Reflector, you need to install Reflector 4 on your Mac or Windows computer.

If your Android device has the option to access the native Cast option, you do not need to install anything on the device in order to mirror.

Directions to mirror via the native Cast option can be found in the article below.
