The basic steps to send video, music, or your screen to Chromecast

Casting from Android to Chromecast works through the Google Home app or through individual apps that support casting — Netflix, YouTube, Spotify, and many others all have a cast button built in. You do not need to pair devices or enter passwords each time. As long as your Android phone and your Chromecast are on the same Wi-Fi network, you can cast with a single tap.

The process differs slightly depending on whether you are casting from an app (like YouTube) or casting your entire screen. Both methods are straightforward once you know where the cast button lives.

Key Takeaways

  • Your Android phone and Chromecast must be connected to the same Wi-Fi network before casting will work.
  • Most streaming apps have a cast icon (a rectangle with curved lines in the corner) built into the player — tap it to send video to your TV.
  • You can cast your entire Android screen to Chromecast through the Quick Settings menu without opening any app.
  • If the cast button does not appear, restart your phone and Chromecast, then check that both are on the same Wi-Fi network.
  • Casting does not require pairing or a PIN — your phone and Chromecast communicate automatically over Wi-Fi.

Check your Wi-Fi connection first

Before you cast anything, make sure your Android phone and your Chromecast are on the same Wi-Fi network. Open Settings on your phone, go to Wi-Fi, and note which network you are connected to. Then check your Chromecast by opening the Google Home app, tapping the device, and looking at the Wi-Fi network listed under Device Info. If they do not match, connect your phone to the same network as your Chromecast.

If your Chromecast is not showing up in the Google Home app at all, restart both devices. Unplug the Chromecast for 10 seconds, plug it back in, and wait for it to fully boot (the light will stop blinking). Then restart your phone. This usually solves connection problems.

Casting from apps like YouTube, Netflix, and Spotify

Most streaming apps have a cast button built in. Look for a rectangle with curved lines in the bottom right or top right corner of the video or music player — that is the cast icon. Tap it, and a list of available devices will appear. Select your Chromecast by name, and the content will start playing on your TV within a few seconds.

Once casting starts, your phone becomes a remote. You can pause, rewind, skip forward, and adjust volume from your phone screen. You can also lock your phone or switch to another app — the content keeps playing on your TV. To stop casting, tap the cast icon again and select Disconnect.

If you do not see a cast icon in an app you use regularly, that app may not support casting. Check the app's settings or help section to confirm. Many older or smaller apps do not have this feature.

Casting your entire Android screen

If you want to show your entire phone screen on the TV — not just a video or song — use screen mirroring. Swipe down from the top of your screen twice to open Quick Settings (the full settings panel). Look for a button called Cast, Screen Cast, or Wireless Display. Tap it, select your Chromecast from the list, and your entire screen will appear on the TV.

Screen mirroring is useful for showing photos, browsing the web, or playing games on a bigger display. The image on your TV updates in real time as you touch your phone. To stop, open Quick Settings again and tap the cast button to disconnect.

Note that screen mirroring uses more battery and Wi-Fi bandwidth than casting from an app. If you notice lag or your phone getting warm, switch back to app-based casting if possible.

Troubleshooting when the cast button does not appear

If you tap the cast icon in an app and no devices show up, or if you cannot find the cast button in Quick Settings, try these steps in order. First, restart your phone completely — hold the power button and select Restart. Second, unplug your Chromecast for 10 seconds and plug it back in. Third, open the Google Home app and confirm your Chromecast is listed and online.

If the cast button still does not appear, check that both devices are truly on the same Wi-Fi network. Some phones have separate 2.4 GHz and 5 GHz networks listed — Chromecast works on both, but your phone must be on the same one. If you have a guest network enabled on your router, make sure you are not connected to that.

If you have tried all of this and casting still does not work, the app itself may not support casting, or there may be a problem with your Wi-Fi router. Try casting from a different app (YouTube is a good test) to narrow down whether the issue is the app or the connection.

What to do if your Chromecast is not showing up in the Google Home app

If your Chromecast does not appear in the Google Home app at all, it may not be set up yet or it may have lost its connection. Open the Google Home app and tap the plus icon to add a device. Select Set up device, then choose Whether you are setting up a new or existing device. Follow the on-screen steps to connect your Chromecast to Wi-Fi.

If your Chromecast was already set up but has disappeared, restart your phone and your router (unplug the router for 30 seconds). Then open the Google Home app again. If the device still does not appear, unplug the Chromecast, wait 30 seconds, and plug it back in. The Google Home app should detect it within a minute or two.

Casting when you are away from home

Casting only works when your phone and Chromecast are on the same Wi-Fi network. You cannot cast to your Chromecast from your phone while you are at work or on the road unless you have set up remote access through the Google Home app.

To enable remote casting, open the Google Home app, tap your profile icon in the top right, go to Settings, and look for Casting options. Some Chromecast models support remote casting, but not all. Check your device's settings in the Google Home app to see if this feature is available.

Frequently Asked Questions

Do I need to pair my phone with Chromecast before I can cast?

No. As long as both devices are on the same Wi-Fi network, casting works when ready without any pairing or PIN entry. The connection is automatic.

Can I cast from multiple phones to the same Chromecast?

Yes. Multiple phones can cast to the same Chromecast, but only one can cast at a time. If two people try to cast simultaneously, the second person's content will replace the first person's.

What happens to my phone while I am casting?

Your phone acts as a remote control. You can lock it, switch to other apps, or even leave the room. The content keeps playing on your TV. To stop casting, open the cast menu and select Disconnect.

Why does the cast button not show up in some apps?

Not all apps support casting. Older apps and some smaller services do not have the feature built in. If an app does not have a cast button, you can use screen mirroring instead to show the entire phone screen on your TV.

Can I cast if my phone is on a different Wi-Fi network than my Chromecast?

No. Both devices must be on the same Wi-Fi network. If your phone is on a guest network and your Chromecast is on your main network, they cannot communicate. Connect your phone to the same network as your Chromecast.
