How to Cast Android to TV? 3 Working Methods

Casting your Android phone or tablet to a TV is simple when both devices share the same Wi-Fi network.

One wrong setting usually causes the whole thing to fail, and it’s almost always the network. The fix comes down to three routes: casting from inside a Google Cast-enabled app, pairing through the Google TV app, or mirroring your whole screen with the Google Home app. Each works on Chromecast, Google TV Streamer (4K), and supported Android TV and Google TV devices.

What You Need Before You Cast

Your phone and the TV receiver must sit on the same Wi-Fi network—the most common cause of failure. Confirm both are connected to the same router and band before troubleshooting anything else.

Google’s Cast help documents specify an Android phone running Android 6.0 or later for casting media from Cast-enabled apps. The TV side usually needs no setup at all—Google Cast is automatically turned on for Android TV and Google TV devices. On other brands, you may need to enable Cast during initial setup or inside the TV’s settings menu. Google also says a secure Wi-Fi network is required for setup, so a completely open network may block pairing.

Method 1: Cast From a Google Cast-Enabled App

This is the most common route, working with over 3,000 Cast-enabled apps. The Cast button looks like a small rectangle with a Wi-Fi-style symbol in the corner, but its location varies by app.

1. Open a Google Cast-enabled app on your Android phone, like YouTube, Netflix, or Spotify.
2. Tap the Cast button—usually near the player controls or in the top corner of the screen.
3. Select your TV or streaming device from the list.
4. When the Cast button turns solid white, casting is active and your media plays on the TV.

Your phone becomes a remote; the TV streams directly from the internet, so you can close the app. To stop, tap the Cast button again and choose Disconnect. Some apps require the latest version to cast, so update the app if the button doesn’t appear.

Method 2: Pair and Cast Using the Google TV App

For TVs without Cast built into every app, Google’s own TV app handles pairing and control—especially well with Google TV and Android TV devices.

1. Open the Google TV app on your Android phone.
2. Tap TVs nearby near the top of the screen.
3. Select your TV from the list, then enter the code shown on the TV screen.
4. Tap Pair.

Once paired, you can browse content on your phone and tap Watch on TV to push playback to the big screen. The pairing persists, so you won’t repeat this setup every time.

Method 3: Cast Your Whole Screen With Google Home

When you need to mirror everything—photos, documents, or apps without Cast support—screen casting is the answer. It mirrors your entire display, not just a single app’s media.

1. Open the Google Home app on your Android phone.
2. Tap the menu icon (three lines), then choose Cast screen / audio.
3. Select your TV or device from the list.

Your phone’s screen appears on the TV in real time. This method drains battery faster than app casting because the phone does the heavy lifting, so keep it plugged in for long sessions. To stop, tap Stop casting in the Google Home app.

Why Casting Fails and How to Fix It

Most failures trace back to the network. If your phone and TV don’t share the same Wi-Fi network—including a guest network or a different band—casting won’t start. Some routers broadcast 2.4GHz and 5GHz under separate names; both devices must be on the same one.

TV brand differences also matter. Google’s documentation notes that setup flows vary by manufacturer, with Vizio and LG as examples. On some sets, Cast is enabled during first-time setup; on others, you’ll dig into the TV’s network or dashboard settings. If the Cast button finds no devices, check the TV’s manual for where Cast lives in its menus.

If you’re shopping for a new set and want built-in Cast without a dongle, many Android TV models support it out of the box. For tested options that fit smaller spaces, our roundup of the best 32-inch Android TVs covers the top picks for bedrooms and kitchens.

When none of the above works, restart both the phone and the TV, then try again. Google’s own docs repeatedly return to the same-network rule as the first thing to verify.
