If you own a Roku-based smart television or if you connect a Roku streaming stick or set-top box to your TV, you have access to thousands of native streaming apps. However, there are some services and applications that are not supported by a native Roku app. That’s where the Roku screen mirroring feature comes in. But how do you cast to Roku from your Android app and how do you mirror to Roku from your Android phone?

In this article, we will show you exactly that. We will also offer up a few app suggestions you can mirror to Roku that are currently not available on its platform.

What’s the difference between casting and mirroring?

Casting and mirroring content are often mistakenly thought of as the same. In reality, they are two different things.

Casting: When you cast content from your phone to your Roku TV, you are only casting the content from one app to a native Roku app. For example, if you want to watch a YouTube video on your Roku TV, you can just cast the content to the YouTube app installed on your Roku device. You can then control the playback of that content from your mobile device. You also have the option to turn off your phone, but you still can watch and control the media on your Roku TV.

Mirroring: Mirroring means you actually display the entire Android phone or tablet screen on your Roku TV. So, for example, you can play games on your Android device, while your friends watch the gameplay on your Roku television. You can also show other streaming apps that are not native to Roku on that TV. However, once you shut off or disconnect your Android device from your Roku, the screen will go back to the regular Roku home screen.

How to cast to Roku from Android

  • First, make sure your Android device is on the same home network as your Roku device.
  • If the mobile app on your phone supports casting to a native Roku app, open it up, and then go to the video content you want to cast.
  • Then, just tap on the casting icon in the app.
  • If you have more than one Roku TV or device on your network, you will be asked to pick which one you want to display the content.
  • Finally, the native Roku app should start casting the content from the mobile app to the Roku TV.

  • First, check to see if your Android phone or tablet will let you mirror your screen to Roku. Some phones may label the feature differently. For example, LG phones may label its casting feature either as Screen Mirroring, or Screen Share. Samsung phones use the term Smart View for screen mirroring. Google Pixel phones, oddly, use the term Cast.
  • Once you find your phone’s screen mirroring feature, just tap on it.
  • If you have more than one Roku TV or device on your network, you will be asked to pick which one you want to display the content.

  • The Roku screen will then show a notification, asking you if you want to cast your screen from your device. You can select “Accept”, or “Always accept” if you want to keep using this same device to mirror your phone’s screen. Alternatively, you can also select “Ignore” or “Always ignore” if you decide not to mirror your phone’s screen.
  • The phone’s screen should then be displayed on your Roku TV.

Apps that you should screen mirror to Roku


Roku used to have a native Twitch app, but it stopped offering it over a year ago. Now, if you want to watch all the great Twitch content on Roku, you must either have kept that old app stored on your device or screen mirror the Android app to your Roku TV.

Spectrum TV

Recently, Roku pulled the dedicated Spectrum TV app from its download store. That was because Roku and Spectrum TV’s parent company Charter Communications were unable to agree to a new contract for the app. That means if you are a new Spectrum TV user, but one or more of your TVs just has a Roku-based device, you can still mirror the Spectrum TV mobile apps for iOS and Android on your TV to watch Spectrum content.


YouTube TV

In early 2021, Roku and Google got in a bit of an argument over renewing YouTube TV‘s contract with Roku. In the end, the two companies failed to reach an agreement and YouTube TV is no longer available to download officially for new Roku owners. If you have YouTube TV installed on your Roku smart TV or streaming device, don’t delete it. However, if you did happen to get rid of the app, you can still mirror YouTube TV on Roku via your mobile device.
