Cast to Roku from Android | How to Screen Mirror From Phone

In this guide, I’ll walk you through how to Cast to Roku from Android. Because the Android mobile operating system largely powers phones and tablets, sharing content on your physical Android device can be difficult because of the smaller screen size.

Android makes it easy to mirror your screen to a Roku device, allowing you to display your Android content on a larger TV screen.

Setting Up Your Roku Player

So, first, we’ll start with the Roku player and ensure these settings are set up correctly.

Check Network Connection
We’re going to our network, and we just want to make sure that we’re connected to the same wireless internet router on both our Roku and our Android cell phone. If you are connected directly through an Ethernet, that’s also fine. We want to ensure that we’re connected to the same Internet source on both our Roku and phone so that the two devices can communicate.

Configure Screen Mirroring
Also, in the settings, we’ll go to System and then Screen Mirroring. We want to make sure that in the Screen Mirroring Mode, it’s selected on Prompt. It should be good to go as long as it’s not on Never Allow. “Prompt” means that when you try to mirror cast over to your Roku, you must select Okay that you accept that casting.

Next, we’ll go to our phone to start this mirror-casting process.

Access Phone Settings
On our phone, we’ll need to drag and drop the top area and then click the little gear to open Settings.
Navigate to Connection Preferences
In the Settings area, we’ll click on Bluetooth and Device Connection, then Connection Preferences, and finally Cast.
Ensure Internet Connection Matches
Again, we need to ensure we’re on the same Internet connection as our Roku and phone. Once we find our Roku player popping up in the Cast area, we can select it so that our device can start communicating with it.

Allowing Screen Mirroring on Roku

Now, back on our Roku, we need to click Allow when this Prompt shows up. Then, it’ll take some time to boot up and get ready to go with that screen mirroring.

Testing Screen Mirroring

Now you can see that your phone is on a Roku player. Play a video to see how this part works.

Play a Video in Portrait Mode
Now, I’m using the YouTube application. I’m just going to play one of my videos in portrait mode.
Switch to Landscape Mode
Then, you rotate your phone, and it changes to landscape so you can get that full-picture view.
