Screen mirroring your Android phone to a Roku device can be a convenient way to enjoy your local media or show friends your vacation photos on the big screen. Roku makes the process of connecting your Android phone an easy one, assuming both devices support the Miracast protocol. While very few Roku devices appear to lack support for screen mirroring, certain Android devices may not support Miracast natively. Below, we'll cover how to mirror your screen to a Roku from the most popular Android devices that support casting — namely, Samsung Galaxy phones and tablets. For example, LG phones have Screen Share, and on OnePlus devices, you'll find Screen Projection.
