The two ways to connect your phone to Roku

Your phone can connect to a Roku TV in two separate ways, and they do different things. Screen mirroring (also called casting) sends your phone's entire display to the TV — useful for showing photos, videos, or anything else on your phone's screen. The Roku mobile app turns your phone into a remote control and lets you search for shows, launch channels, and adjust volume without needing the physical remote.

Most people use both at different times. The app is faster for everyday control. Screen mirroring is better when you want to show someone something from your phone or play a video stored on your device. Both require your phone and TV to be on the same Wi-Fi network.

Key Takeaways

  • Screen mirroring requires your phone and Roku TV to be on the same Wi-Fi network, and the process differs between iPhones (AirPlay) and Android phones (built-in casting).
  • The Roku mobile app works as a remote control and search tool, and you download it from the Apple App Store or Google Play Store, then sign in with your Roku account.
  • If your phone and TV are not on the same network, screen mirroring will not work, but the Roku app can still function if you are signed into your Roku account.
  • Roku TV models from 2019 onward support screen mirroring, but older models may not — check your TV's manual or settings if casting does not appear as an option.

Screen mirroring from an iPhone to Roku

iPhones use AirPlay to send their screen to compatible devices. Open Control Center (swipe down from the top-right corner on newer iPhones, or up from the bottom on older ones), then tap Screen Mirroring. You will see a list of devices on your network. Select your Roku TV by name — it usually appears as "Living Room" or "Bedroom" or whatever you named it during setup.

Your iPhone screen will appear on the TV within a few seconds. The TV will show a small AirPlay icon in the corner. To stop mirroring, open Control Center again, tap Screen Mirroring, then tap Stop Mirroring. If your Roku TV does not appear in the list, make sure both devices are connected to the same Wi-Fi network and that your TV is powered on.

Screen mirroring from an Android phone to Roku

Android phones have a built-in casting feature, though the name and location vary by manufacturer. Look for Cast, Screen Cast, or Smart View in your phone's quick settings (swipe down twice from the top). Tap the casting option, then select your Roku TV from the list of available devices.

Some Android phones require you to go into Settings instead. If you cannot find casting in quick settings, try Settings > Display > Cast (or Screen Mirroring). Once you select your TV, your phone's screen will mirror to it. To disconnect, tap the casting icon again and select Stop Casting or Disconnect.

Using the Roku mobile app as a remote

Download 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 — the same account you used to set up your TV. The app will automatically find your Roku TV on your home network.

Once connected, you can use your phone as a remote: press buttons to navigate menus, search for shows by typing on your phone's keyboard, and control volume and power. The app also shows you what is currently playing on the TV. If the app cannot find your TV, restart both your phone and TV, then try again.

Troubleshooting when your phone will not connect

The most common reason a phone will not connect to Roku is that they are on different Wi-Fi networks. Check that both devices are connected to the same network — look at your phone's Wi-Fi settings and your TV's network settings (usually under Settings > Network on Roku). If you have a 2.4 GHz and 5 GHz network with the same name, try connecting your phone to the same band your TV is using.

If screen mirroring still does not work, restart your TV by unplugging it for 30 seconds, then plugging it back in. Restart your phone as well. If you are using the Roku app and it cannot find your TV, sign out of the app completely, restart your phone, then sign back in. For older Roku TV models (before 2019), screen mirroring may not be supported — check your TV's manual or go to Settings > System > About to see your model number and search Roku's support site for that specific model.

What to do if your Wi-Fi network is unstable

Screen mirroring and the Roku app both depend on a stable connection between your phone and TV. If your Wi-Fi keeps dropping or is very slow, mirroring may lag or disconnect. Move your phone and TV closer to your router, or move the router away from walls and metal objects that block the signal.

If you have many devices on your network, try disconnecting some temporarily to see if that improves the connection. You can also try restarting your router by unplugging it for 30 seconds. If the problem persists, contact your internet provider — the issue may be with your connection speed rather than the devices themselves.

Frequently Asked Questions

Can I use the Roku app if my phone is on a different Wi-Fi network than my TV?

Yes, the Roku app can work over the internet if you are signed into your Roku account, even if your phone is on a different network. However, screen mirroring requires both devices to be on the same Wi-Fi network and will not work across different networks or over cellular data.

Does screen mirroring use a lot of battery on my phone?

Yes, screen mirroring drains battery faster than normal use because your phone is constantly sending video to the TV. If you are mirroring for a long time, keep your phone plugged in or use the Roku app as a remote instead, which uses much less battery.

Why does my screen mirroring keep disconnecting?

Disconnections usually happen because of Wi-Fi interference or a weak signal. Try moving closer to your router, reducing the number of devices on your network, or switching to a less crowded Wi-Fi channel. If your TV is far from the router, consider moving the router or using a Wi-Fi extender.

Can I mirror my phone to Roku without the Roku app installed?

Yes, screen mirroring works without the app — it uses your phone's built-in casting feature (AirPlay for iPhone, Cast for Android). The Roku app is separate and is only needed if you want to use your phone as a remote control.

What if I forgot my Roku account password?

Go to the Roku website and click Forgot Password on the sign-in page. Enter your email address and follow the link sent to your inbox to reset your password. Once you have reset it, sign into the Roku app with your new password.
