The basics of controlling Chromecast

You control Chromecast through the Google Home app on your phone or tablet, or by casting directly from compatible apps on your phone, computer, or tablet. The device itself has no remote — instead, your phone becomes the remote. You can pause, play, adjust volume, and skip forward or backward from your phone's screen, and you can also use voice commands through a Google Home speaker or your phone's microphone.

The first time you set up Chromecast, you connect it to your Wi-Fi network through the Google Home app. After that, any device on the same Wi-Fi network can cast to it. You don't need to pair devices the way you would with Bluetooth — as long as they're on the same network, casting works.

Key Takeaways

  • read the Google Home app on your phone or tablet to see all Chromecast devices on your network and control them from one place.
  • Cast content directly from apps like YouTube, Netflix, and Spotify by tapping the cast icon inside the app itself.
  • Control playback — play, pause, volume, and skip — from your phone's screen while content is casting to your TV.
  • Use voice commands by saying "Hey Google" followed by your command if you have a Google Home speaker, or by tapping the microphone in the Google Home app.
  • Adjust Chromecast settings like Wi-Fi network, device name, and display preferences through the Google Home app's device settings menu.

Casting from apps on your phone

Most streaming apps — YouTube, Netflix, Spotify, Disney+, Hulu, and many others — have a cast icon built in. It usually looks like a rectangle with a curved line in the corner. Open the app, start playing the content you want, and tap the cast icon. A menu appears showing all Chromecast devices on your network. Tap the one you want to cast to, and the content moves to your TV within a few seconds.

Once casting starts, your phone screen goes dark or shows a smaller version of what's on the TV. You can lock your phone, use other apps, or even turn the screen off — the casting continues. Your phone is still controlling playback, but you're not watching the phone screen anymore.

If the cast icon doesn't appear in an app you're using, that app doesn't support casting. You can still mirror your entire phone screen to Chromecast instead, though this uses more battery and can be slower. To mirror, open the Google Home app, tap the device you want to cast to, tap the three dots in the top right, and select "Cast my screen."

Using the Google Home app to control playback

The Google Home app is the central control point for all your Chromecast devices. Open it and you see a list of every Chromecast on your network. Tap the device you're currently casting to, and a playback card appears showing what's playing, the current volume, and buttons to play, pause, skip forward, and skip backward.

You can adjust the volume by dragging the volume slider on the card, or by tapping the volume icon to mute and unmute. If you're casting music, you can see the current song and artist, and skip to the next or previous track. If you're casting video, you can see how far through the content you are and tap anywhere on the progress bar to jump to a different point.

The Google Home app also shows you what's casting right now on each device. If someone else in your home is casting to the living room TV, you can see it in the app and take over if you want — though this will interrupt what they're watching.

Controlling Chromecast with voice commands

If you have a Google Home speaker or display in your home, you can control Chromecast by voice. Say "Hey Google" followed by a command like "pause the living room TV," "turn up the volume," or "skip to the next song." The speaker sends the command to your Chromecast device, and it happens when ready.

You can also use voice commands through your phone. Open the Google Home app, tap the microphone icon at the bottom, and speak your command. This works the same way as speaking to a Google Home speaker. Voice commands work best when you're specific about which device you're controlling — for example, "pause the bedroom Chromecast" rather than just "pause."

Common voice commands include: "play [show or song name]," "pause," "resume," "skip," "next," "previous," "turn up the volume," "turn down the volume," "mute," and "unmute." You can also ask Google to cast specific content — for example, "Hey Google, play The Office on the living room TV" — and it will find the content and start casting it automatically if the app is available on your phone.

Adjusting Chromecast settings

To change how your Chromecast works, open the Google Home app and tap and hold on the device you want to adjust. A menu appears with options to rename the device, change the Wi-Fi network it's connected to, adjust display settings, and more.

The most common settings you'll adjust are: the device name (so you can tell which Chromecast is which if you have more than one), the Wi-Fi network (if you change your home network), and the display settings (like whether to show a screensaver or backdrop when nothing is casting). Some Chromecast models also let you adjust picture quality and audio settings.

If your Chromecast stops responding or casting isn't working, the first step is to restart it. Unplug the device for 10 seconds, then plug it back in. Wait for it to fully restart — this usually takes about a minute — and try casting again. If that doesn't work, make sure your phone and Chromecast are on the same Wi-Fi network.

Troubleshooting common control problems

If the cast icon doesn't appear in an app, the app may not support casting, or your phone and Chromecast may not be on the same network. 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 or a different band of your Wi-Fi (like 5GHz instead of 2.4GHz), casting won't work.

If casting starts but then stops, or if playback is choppy, your Wi-Fi signal may be weak. Move your Chromecast closer to your router, or move your router closer to your TV. Interference from other devices can also cause problems — try moving your phone away from the Chromecast while casting, or restart your router.

If your phone can see the Chromecast in the Google Home app but casting fails, try restarting both your phone and your Chromecast. Unplug the Chromecast for 10 seconds, plug it back in, and wait for it to fully restart before trying again. If the problem persists, you may need to remove the device from the Google Home app and set it up again from scratch.

Casting from a computer or tablet

You can cast from a Mac or Windows computer using Google Chrome. Open Chrome, click the three dots in the top right corner, and select "Cast." A menu appears showing all Chromecast devices on your network. Select the one you want to cast to. You can then cast a tab, your entire screen, or a file.

On an iPad or Android tablet, casting works the same way as on a phone — open a compatible app, tap the cast icon, and select your Chromecast. The Google Home app also works on tablets, so you can control playback from a tablet even if someone else is casting from a phone.

If you're casting from a computer and want to stop, click the cast icon in Chrome and select "Stop casting." The content will stop playing on your TV, but the Chromecast will remain connected to your network and ready to receive new casts.

Frequently Asked Questions

Can multiple people cast to the same Chromecast at the same time?

No. Only one device can cast to a Chromecast at a time. If someone else tries to cast while you're already casting, they'll see a prompt asking if they want to take over. If they confirm, your casting stops and theirs begins. You can prevent this by locking the device in the Google Home app settings, which requires a PIN to take over.

Do I need to be on the same Wi-Fi network to control Chromecast?

Yes. Your phone and Chromecast must be on the same Wi-Fi network to cast or control playback. If you're away from home and connected to a different network, you won't be able to cast. However, if you have a Google Home speaker or display at home, you can still control Chromecast by voice through that speaker, even if you're not home.

Why does my Chromecast keep disconnecting from Wi-Fi?

This usually happens if your Wi-Fi signal is weak or if your router is dropping the connection. Try moving your Chromecast closer to your router, or restart your router by unplugging it for 30 seconds. If the problem continues, check if your router is set to a 5GHz-only network — some older Chromecast models only work on 2.4GHz. You can usually change this in your router settings.

Can I control Chromecast if I don't have a smartphone?

If you have a Google Home speaker or display, you can control Chromecast by voice without a smartphone. You can also use a computer with Google Chrome to cast and control playback. However, the Google Home app (which requires a smartphone or tablet) is the easiest way to manage multiple devices and adjust settings.

What happens if I turn off my phone while casting?

The content will continue playing on your TV. Your phone is only needed to start the cast and control playback — once casting begins, the Chromecast connects directly to the internet and doesn't rely on your phone. You can turn your phone off, lock it, or use other apps, and the casting continues uninterrupted.
