The Three Ways to Control Chromecast
You control a Chromecast through your phone, tablet, or computer — the device itself has no remote and no buttons except power. The most common method is the Google Home app, which works on Android and iOS and lets you cast video, music, and photos from your device to your TV. You can also cast directly from apps like YouTube, Netflix, and Spotify without opening Google Home first. A third option is Google Cast for Chrome, a browser extension that lets you send what's on your computer screen to the TV.
Once something is casting, you control playback — pause, play, volume, skip — from the same app you used to start it. If you have a Google Home speaker or display in the same room, you can also use voice commands to control the Chromecast without touching your phone.
Key Takeaways
- The Google Home app is the main control hub for Chromecast and works on both Android and iOS phones and tablets.
- Most streaming apps like YouTube, Netflix, and Spotify have a built-in cast button that sends video or music directly to your TV without needing Google Home.
- You control playback — pause, play, volume, and skip — from whichever app you used to start casting.
- Google Cast for Chrome on your computer lets you mirror your browser or cast specific tabs to your TV.
- Voice commands through a Google Home speaker or display can pause, play, and adjust volume without touching your phone.
Using the Google Home App to Control Chromecast
Open the Google Home app on your phone or tablet and tap the device icon in the top right corner. Select your Chromecast from the list of devices. From here you can see what's currently casting and control volume with the slider. You can also cast content by tapping the cast icon inside any compatible app — YouTube, Spotify, Google Photos, and hundreds of others have this button built in.
The Google Home app also lets you adjust settings like the device name, Wi-Fi network, and display preferences. If you want to stop casting, tap the cast icon again and select "Stop casting" — this disconnects your phone from the Chromecast but leaves the TV on the last thing that was playing.
Casting From Individual Apps
Most streaming and media apps have their own cast button, usually in the top right or bottom corner of the screen. In YouTube, it's a rectangle with a corner bracket. In Spotify, it's a speaker icon with a Wi-Fi symbol. Tap this button, select your Chromecast, and the app takes over the controls — you pause and play from the app itself, not from Google Home.
This method is faster than opening Google Home first because you stay inside the app you're already using. The cast button appears only when a Chromecast is on the same Wi-Fi network as your phone, so if you don't see it, check that both devices are connected to the same network.
Controlling Playback and Volume
Once something is casting, the app you used to start it becomes your remote. Pause and play buttons appear on the screen, along with a volume slider. On your phone's lock screen, you'll also see playback controls if something is actively casting — this lets you pause a video without unlocking your phone.
To change the volume, use the volume buttons on the side of your phone, or use the slider in the app itself. If you have a Google Home speaker in the same room, you can say "Hey Google, pause" or "Hey Google, turn up the volume" and the Chromecast will respond. The TV's remote does not control Chromecast — only your phone, tablet, computer, or voice commands work.
Casting Your Computer Screen or Browser Tabs
Install Google Cast for Chrome from the Chrome Web Store, then click the extension icon in your browser toolbar. Select "Cast" and choose your Chromecast. You can cast your entire screen or just the current tab — "Cast tab" is useful if you want to watch a video in your browser without mirroring everything else on your desktop.
Screen mirroring sends everything on your computer to the TV, which is helpful for presentations or showing photos stored on your hard drive. Tab casting is faster and uses less bandwidth because only the browser tab is sent, not your whole screen. To stop, click the Cast icon again and select "Stop casting."
Troubleshooting Connection Problems
If the cast button doesn't appear in an app, make sure your phone and Chromecast are on the same Wi-Fi network. Check that your Chromecast is powered on — the light on the device should be solid white or blue, not blinking. Restart your phone's Wi-Fi or restart the Chromecast by unplugging it for 10 seconds and plugging it back in.
If an app keeps disconnecting while casting, try moving your phone closer to the router or Chromecast, as distance and walls can weaken the signal. Some apps also require you to be signed into the same Google account on both your phone and Chromecast. Check the app's settings or help section if casting still doesn't work.
Using Voice Commands to Control Chromecast
If you own a Google Home speaker or display, you can control a Chromecast in the same room using voice. Say "Hey Google, pause" to pause what's playing, "Hey Google, play" to resume, or "Hey Google, turn up the volume" to increase sound. You can also ask Google Home to cast specific content: "Hey Google, play The Office on the living room TV" will search for that show and start playing it on your Chromecast.
Voice control works best when the Google Home device is in the same room as the Chromecast and both are on the same Wi-Fi network. You don't need to hold a button or unlock your phone — just speak naturally and Google Home listens.
Frequently Asked Questions
Can I control Chromecast without the Google Home app?
Yes. Most streaming apps like YouTube, Netflix, and Spotify have their own cast buttons and let you control playback without opening Google Home. You only need Google Home if you want a central control hub for all your devices or if you're casting from Google Photos or Chrome.
What if my phone and Chromecast are on different Wi-Fi networks?
They must be on the same network to communicate. Check your phone's Wi-Fi settings and make sure it's connected to the same network name as your Chromecast. If you're on a guest network, try switching to the main network.
Can I use my TV remote to control Chromecast?
No. Chromecast does not respond to your TV remote. You must use your phone, tablet, computer, or voice commands through a Google Home device. The TV remote can only change inputs and adjust the TV's built-in settings.
Does casting use a lot of data?
Casting streams video or music from the internet to your Chromecast, so it uses your home Wi-Fi bandwidth. It does not use your phone's data plan. If you're on a limited Wi-Fi plan, streaming will count toward that limit.
Can multiple people control the same Chromecast at the same time?
Yes, but only one person can cast at a time. If two people try to cast simultaneously, the second request interrupts the first. Multiple people can control volume and playback of what's already casting, but only one device can send new content to the TV.
