The Basic Steps to Cast from Android

To cast from your Android phone to a TV with Chromecast, open any app that supports casting, tap the cast icon (it looks like a rectangle with curved lines in the corner), select your Chromecast device from the list, and the content appears on your TV. Your phone and TV must be on the same Wi-Fi network. The cast icon appears in apps like YouTube, Netflix, Google Photos, Chrome, and many others — not all apps support it, but the major ones do.

The whole process takes about 10 seconds once you know where the cast button is. After you tap it, your phone becomes a remote control for what's playing on the TV. You can pause, rewind, adjust volume, or stop casting from your phone at any time.

Key Takeaways

  • Your Android phone and Chromecast device must be connected to the same Wi-Fi network before casting will work.
  • The cast icon appears in supported apps like YouTube, Netflix, and Google Photos, usually in the top or bottom corner of the screen.
  • After you select your Chromecast, the content streams to your TV while your phone acts as a remote control.
  • You can cast the entire screen of your Android phone to the TV if the app doesn't have a built-in cast button.
  • Casting stops when you disconnect, and your phone screen returns to normal — you don't have to do anything else.

Setting Up Your Phone and Chromecast on the Same Network

Before you can cast anything, both devices need to be on the same Wi-Fi network. Check your phone's Wi-Fi settings and note which network you're connected to. Then check your Chromecast — during setup, you chose a Wi-Fi network for it. If they don't match, your phone won't see the Chromecast when you tap the cast button.

If you recently changed your Wi-Fi password or moved your router, your Chromecast might be trying to connect to an old network. In that case, you'll need to set it up again. Unplug the Chromecast for 10 seconds, plug it back in, and follow the on-screen prompts on your phone to reconnect it to your current Wi-Fi.

Finding and Tapping the Cast Icon in Apps

The cast icon looks like a small rectangle with three curved lines in one corner — it resembles a TV with a signal. In YouTube, it's usually in the top right corner. In Netflix, it's often in the top right as well. In Google Photos, it's typically at the top. The exact location varies by app, but it's always visible when casting is available.

If you don't see a cast icon in an app you're using, that app doesn't support casting. Google's own apps (YouTube, Google Photos, Google Play Music) always have it. Many third-party apps like Netflix, Spotify, Hulu, and Disney+ support it too. If you're unsure, look for the icon or check the app's menu — usually a three-dot icon or settings button.

Selecting Your Chromecast Device from the List

When you tap the cast icon, a small menu appears showing all Chromecast devices on your network. Each one is labeled with a name — often something like "Living Room" or "Bedroom" depending on what you named it during setup. Tap the name of the device you want to cast to.

If you only see one Chromecast, it will be selected automatically. If you see multiple devices and pick the wrong one, just tap the cast icon again and choose a different device. Switching between Chromecasts takes a few seconds.

Casting Your Entire Phone Screen to the TV

If an app doesn't have a built-in cast button, you can still cast your entire phone screen. This is called screen mirroring. On most Android phones, swipe down from the top of the screen twice to open the quick settings menu, then look for "Cast" or "Screen cast." Tap it, select your Chromecast, and your whole phone screen appears on the TV.

Screen mirroring uses more battery and data than casting from within an app, and there's a slight delay between what you do on your phone and what appears on the TV. But it works for any app, including ones that don't officially support casting. To stop screen mirroring, tap the cast icon again and select "Disconnect."

Troubleshooting When Your Phone Won't Find the Chromecast

If you tap the cast icon and don't see your Chromecast in the list, the most common cause is that your phone and Chromecast are on different Wi-Fi networks. Check your phone's Wi-Fi settings and make sure you're connected to the same network as your Chromecast. If you're on a guest network and your Chromecast is on the main network, they won't see each other.

If both devices are on the same network and you still don't see it, restart both. Unplug the Chromecast for 10 seconds, plug it back in, and wait for it to fully boot (the light on the device will stop blinking). On your phone, toggle Wi-Fi off and back on. Then try casting again.

If your Chromecast is very far from your router or there are thick walls between them, the connection might be weak. Move the Chromecast closer to the router or move your phone closer to the Chromecast and try again. Interference from other devices on the same Wi-Fi band can also cause problems — if you have many devices connected, try disconnecting a few temporarily.

What Happens While You're Casting

Once casting starts, your phone screen usually goes back to normal — you're not watching the video on your phone anymore, it's on the TV. Your phone becomes a remote. You can pause, play, skip forward or backward, adjust volume, and control subtitles all from your phone while the content plays on the TV.

You can also lock your phone, open other apps, or even leave the room — the content keeps playing on the TV. The only thing that stops casting is if you manually disconnect (by tapping the cast icon and selecting "Disconnect"), if your phone loses Wi-Fi connection, or if you turn off the Chromecast.

Frequently Asked Questions

Does my phone screen show the same thing as the TV while I'm casting?

Not usually. When you cast from within an app like YouTube, your phone screen goes back to normal and you use it as a remote. When you screen mirror (cast your entire screen), your phone and TV show the same thing, but there's a slight delay.

Can I cast from my Android phone to a TV that doesn't have Chromecast built in?

Only if you plug a Chromecast device into the TV's HDMI port. Chromecast is a separate device or feature — it's not built into all TVs. If your TV doesn't have it, you need to buy a Chromecast dongle or a TV with Chromecast built in.

What if I'm on a work or school Wi-Fi network?

Some networks block Chromecast devices or don't allow devices to communicate with each other. If you're on a network like that, casting won't work. You'd need to use a personal Wi-Fi hotspot from your phone instead, though that drains your phone battery quickly.

Can I cast while using my phone for something else?

Yes, as long as you're casting from within an app. Your phone screen returns to normal, so you can text, browse, or use other apps while the video plays on the TV. If you're screen mirroring, your phone screen is locked to what's on the TV.

Why does casting sometimes stop on its own?

If your phone loses Wi-Fi connection, moves out of range, or your Chromecast loses power, casting stops. If your phone goes to sleep, casting usually continues, but some apps pause playback. Check that both devices are still on the same network and that your router is working.
