How to Stream to Roku from Your Phone

Conveniently and timely casting your phone to a Roku device makes the experience even more satisfying. The initial setup to achieve this may take a few minutes the first time.

However, the good news is that once you complete the initial process, you'll be able to stream from your phone to your Roku device in no time.

Before streaming from your phone to Roku

  1. Download the Roku Remote app on your mobile device.
  2. Connect your phone and your Roku device to the same Wi-Fi network. The Roku app will only work if both devices are connected to the same Wi-Fi network.
  3. Make sure the mobile app you want to stream from is also installed on your Roku device.

Note: If you want to stream a subscription-based app like Netflix, you need to sign into the same user account on your phone and the Roku device. This step will not be necessary for applications that do not require a connection, such as YouTube.

After completing this unique setup, streaming will be effortless.

Streaming from your phone to your Roku

  1. Open the app you want to cast to Roku. You don't need to open the streaming app on your Roku.
  2. Tap the Casting icon inside the app.
  3. Select your Roku device when prompted on your phone screen.
  4. The app will automatically launch on your TV screen.

What you need to know about streaming on Roku

Casting gives you the ability to access other apps on your phone without interrupting your TV screen. You also have the option to turn off your phone while streaming.

For playback, you can use your mobile device or the Roku remote. You cannot share personal videos or photos via broadcast. You will need to use the free Roku mobile app for this.

You will know if an app is available for casting by the presence of the casting icon in the app. Remember that some apps will only show you the casting icon after you start playing a video.


It is important to note the difference between casting and mirroring your screen. These terms are often confused when casting mobile devices to your TV screen via Roku. Still, these are differences you should be aware of before choosing the feature that best suits your needs.

Unlike casting, mirroring gives you the ability to mirror your entire mobile device to your Roku. Which means your TV will show the exact layout of your phone, including all the buttons. All the actions you perform on the phone will be reflected on the screen. When casting, you can only see one app at a time.

Another difference to keep in mind when mirroring is that your mobile device must remain on for the duration of its use. Unlike casting, you can't use other apps on your phone or turn it off without interrupting your Roku's mirroring. Everything you do on your phone will be reflected on the screen.

Casting only works on apps that support casting while mirroring lets you see all the apps available on your phone. Which makes it a useful workaround when you want to cast unsupported apps to Roku. Having the same app available on Roku and your phone is a prerequisite for streaming.

At the moment, mirroring is only available on Android and Windows devices. However, the Roku OS 9.4 update soon promises Airplay 2 for iPhones on select 4K devices. This update will allow iPhone users to stream content from personal libraries and apps.

The benefits of streaming from mobile-to-Roku

Casting can save you time searching your Roku device once you complete the initial setup process. And it's a great workaround for iPhone users looking to stream content from their devices without having to mirror their screens.
