The basic connection process

You can connect your phone to your Roku TV in two main ways: through the official Roku mobile app, or by casting content directly from apps that support Roku. The Roku app is the most reliable method and works on both iPhone and Android phones. You'll need your phone and TV on the same Wi-Fi network, and the TV must be powered on and set up with a Roku account.

The Roku app lets you control your TV like a remote, browse channels, and cast photos, music, and videos. If you want to mirror your entire phone screen to the TV, that's a different process called screen mirroring, which works differently depending on whether you have an iPhone or Android phone.

Key Takeaways

  • Download the Roku app on your phone, sign in with the same Roku account linked to your TV, and both devices must be on the same Wi-Fi network.
  • Once connected, the app acts as a remote control and lets you cast compatible content like photos, music, and videos to your TV.
  • Screen mirroring (showing your entire phone screen) requires AirPlay on iPhones or the built-in cast feature on Android phones, not the Roku app.
  • If your phone won't connect, restart both devices, check that they're on the same network, and make sure your Roku TV is fully set up with a Roku account.

Connecting through the Roku mobile app

Start by downloading the Roku app from the Apple App Store (for iPhone) or Google Play Store (for Android). Open the app and sign in with your Roku account — this must be the same account you used to set up your Roku TV. If you don't have a Roku account yet, you'll need to create one before the app can find your TV.

Make sure your phone and TV are connected to the same Wi-Fi network. The app will search for available Roku devices on that network. When your TV appears in the list, tap it to connect. Once connected, you'll see a remote control interface on your screen. The app is now ready to use as a remote, and you can navigate channels, adjust volume, and change inputs from your phone.

If the app doesn't find your TV automatically, you can manually add it. In the app, look for an option to add a device by entering your TV's IP address or serial number. You can find this information in your TV's settings menu under System or Network.

Casting content from your phone to the TV

Many apps on your phone — including YouTube, Netflix, Spotify, and others — have a built-in cast button that lets you send content directly to your Roku TV. Look for a cast icon (usually a rectangle with a Wi-Fi symbol in the corner) within the app you're using. Tap it, select your Roku TV from the list, and the content will start playing on your TV.

Not all apps support casting to Roku. If you don't see a cast button in an app, that app doesn't have Roku casting built in. In those cases, you can use screen mirroring instead, though the experience may be slower or less reliable than native casting.

Screen mirroring from iPhone

To mirror your entire iPhone screen to a Roku TV, you'll use AirPlay, not the Roku app. First, make sure your iPhone and Roku TV are on the same Wi-Fi network. On your iPhone, swipe down from the top-right corner to open Control Center. Tap Screen Mirroring, then select your Roku TV from the list.

Your iPhone screen will now appear on your TV. To stop mirroring, open Control Center again, tap Screen Mirroring, and select Stop Mirroring. Keep in mind that AirPlay mirroring can be slower than casting native apps, and some content (like streaming video from certain apps) may not mirror due to copyright protection.

Screen mirroring from Android

Android phones use a feature called Cast or Screen Cast to mirror to Roku TVs. The exact name and location depends on your phone's manufacturer and Android version. On most phones, swipe down twice from the top to open the full Quick Settings menu, then look for Cast, Screen Cast, or Smart View. Tap it and select your Roku TV from the available devices.

Your Android screen will now mirror to the TV. To disconnect, open Quick Settings again and tap the cast option to stop. Like iPhone mirroring, Android screen casting can be slower than casting from individual apps, and some protected content won't display.

Troubleshooting connection problems

If your phone won't connect to your Roku TV, start by restarting both devices. Turn off your TV completely, wait 30 seconds, and turn it back on. Restart your phone the same way. Then try connecting again through the Roku app or casting from an app.

Check that both devices are on the same Wi-Fi network. Your phone and TV must be connected to the same network name (SSID) — if your router has separate 2.4 GHz and 5 GHz networks, try connecting both devices to the same band. If your Roku TV isn't showing up in the app at all, go to your TV's Settings menu and confirm it's connected to Wi-Fi and signed into a Roku account.

If casting works but is very slow or keeps stopping, move your phone closer to the router or TV, as weak Wi-Fi signal can interrupt the connection. You can also try switching to a different Wi-Fi band if your router supports it. If problems persist, restart your router by unplugging it for 30 seconds, then plugging it back in.

Frequently Asked Questions

Do I need a Roku account to connect my phone?

Yes, you need a Roku account on both your phone and your TV, and they must be the same account. The account is free to create. Without it, the Roku app won't be able to find or communicate with your TV.

Can I control my Roku TV from my phone without Wi-Fi?

No, your phone and TV must be on the same Wi-Fi network to connect. The Roku app and casting both require an active Wi-Fi connection between the devices.

What's the difference between casting and screen mirroring?

Casting sends specific content (like a YouTube video) from an app to your TV, while screen mirroring shows everything on your phone screen on the TV. Casting is faster and more reliable, but only works with apps that support it. Screen mirroring works with any app but can be slower.

Why does my phone keep disconnecting from my Roku TV?

Weak Wi-Fi signal is the most common cause. Move closer to your router, or check if other devices are using a lot of bandwidth. You can also try restarting your router and TV. If disconnections happen only with screen mirroring, try casting from individual apps instead, which is more stable.

Can I use my phone as a remote if I'm away from home?

The Roku app can control your TV remotely if you're signed into your Roku account and your TV is connected to Wi-Fi at home. However, casting content requires both devices to be on the same network, so remote casting won't work.
