The fastest way to mirror your Samsung phone to your TV

Samsung phones connect to Samsung TVs wirelessly through SmartThings, the built-in mirroring feature that works without cables or extra apps. On your phone, swipe down twice from the top to open the full Quick Settings panel, tap Smart View, select your TV from the list, and your phone screen appears on the TV within seconds. The TV must be on the same Wi-Fi network as your phone, and both devices need to be within normal Wi-Fi range.

If you have an older Samsung TV or a non-Samsung TV, you can use Miracast, which is built into most Android phones and works with any TV that supports it. The steps are the same—open Quick Settings, find the screen mirroring option (sometimes called Wireless Display or Cast), and select your TV. Some Samsung TVs also support Chromecast or AirPlay if you prefer those standards, though SmartThings is usually the simplest choice for Samsung-to-Samsung connections.

Key Takeaways

  • SmartThings is the native mirroring feature on Samsung phones and TVs and requires only that both devices are on the same Wi-Fi network.
  • Open Quick Settings on your phone by swiping down twice, tap Smart View, and select your TV from the available devices list.
  • Mirroring begins within a few seconds and shows your entire phone screen on the TV, including notifications and status bar.
  • If your TV is not Samsung or is older, use Miracast (called Wireless Display on some phones) instead, which works with most modern TVs.
  • Your phone and TV must be connected to the same Wi-Fi network for any wireless mirroring method to work.

Setting up SmartThings mirroring on a Samsung TV

Before you mirror, make sure your Samsung phone and TV are both connected to the same Wi-Fi network. Check your phone's Wi-Fi settings by opening Settings, tapping Connections, and confirming the network name. On your TV, go to Settings (usually accessed with the remote's menu button), navigate to Network, and verify it is on the same network. If the TV shows a different network, select your home Wi-Fi and enter the password.

Once both devices are on the same network, unlock your Samsung phone and swipe down from the top of the screen twice to open the full Quick Settings panel. You will see a grid of options including Bluetooth, Wi-Fi, and other toggles. Look for Smart View (on newer Samsung phones) or Screen Mirroring (on older models). Tap it, and your phone will scan for available devices. Your TV should appear in the list within 5 to 10 seconds. Tap your TV's name, and the connection will establish automatically.

Your phone screen will now appear on the TV. The mirroring includes everything on your phone—apps, videos, photos, and notifications. To stop mirroring, swipe down to Quick Settings again, tap Smart View, and select Disconnect. You can also stop from the TV remote by pressing the input button and switching to a different source.

Using Miracast if your TV is not Samsung

Miracast is a wireless standard that works across brands and is built into most Android phones and modern TVs. If your TV does not have SmartThings or you are connecting to a non-Samsung TV, Miracast is usually the next option. The process is nearly identical to SmartThings: open Quick Settings on your phone, look for Wireless Display, Cast, or Screen Mirroring (the name varies by phone model and Android version), and tap it.

Your phone will search for available Miracast devices. Select your TV from the list. Some TVs require you to enable Miracast in their settings first—check your TV manual or settings menu for an option called Miracast, Screen Mirroring, or Wireless Display. Once enabled, your TV will appear in your phone's scan results. The connection usually takes 10 to 15 seconds. If your TV does not appear, restart both devices and try again.

Miracast works over Wi-Fi Direct, which means your phone and TV do not always need to be on the same home network, though they must be within Wi-Fi range. This can be useful if you are at a hotel or office with a Miracast-enabled display. Performance is usually smooth for video and photos, though some older TVs may experience lag with fast-moving content.

Troubleshooting when your phone will not connect

If your TV does not appear in the Smart View or Miracast list, the most common cause is that your phone and TV are on different Wi-Fi networks. Open your phone's Wi-Fi settings and confirm both devices are connected to the same network name. If your home has a 2.4 GHz and 5 GHz network with the same name, try connecting both devices to the 2.4 GHz band, as some older TVs do not support 5 GHz.

If both devices are on the same network and the TV still does not appear, restart your TV by unplugging it for 30 seconds, then plugging it back in. While the TV restarts, restart your phone by holding the power button and selecting Restart. Once both devices are back on, try the mirroring process again. This clears temporary connection issues that prevent discovery.

If the TV appears in the list but the connection fails after you select it, check that your TV's mirroring feature is turned on. On Samsung TVs, go to Settings, select General, then find Wireless Display or SmartThings and make sure it is set to On. On non-Samsung TVs, look for a Miracast or Screen Mirroring setting in the TV's main menu. Some TVs also have a dedicated input or source button for wireless displays—check your TV remote or manual.

If you see a connection prompt on your TV asking you to allow the phone to connect, select Yes or Allow on the TV remote. Some TVs require this approval the first time a new phone connects. After you approve it once, future connections from the same phone usually connect without prompting.

What to expect once you are mirrored

Once your phone is mirrored, everything on your phone screen appears on the TV in real time. If you open an app, swipe between screens, or change the brightness, the TV updates when ready. Audio from videos and apps plays through the TV's speakers by default, though you can adjust this in your phone's sound settings if you want audio to come from your phone instead.

Mirroring uses Wi-Fi bandwidth, so your internet speed affects video quality. On a typical home Wi-Fi network, video streams smoothly and photos display clearly. If you are streaming video from the internet while mirrored, you may notice slight buffering if your Wi-Fi signal is weak. Move closer to your router or reduce the number of other devices using Wi-Fi to improve performance.

Your phone remains fully usable while mirrored—you can receive calls, texts, and notifications, and they will appear on both your phone and the TV. If you want to hide notifications from the TV, some phones have a Do Not Disturb mode that silences alerts without disconnecting the mirror. Battery drain is moderate; mirroring for an hour typically uses 10 to 15 percent of your phone's battery.

Using Chromecast or AirPlay as alternatives

If your Samsung TV has Chromecast built in (many newer models do), you can use Google's Cast feature instead of SmartThings. Open any app that supports Cast—YouTube, Netflix, Google Photos, and others—and look for the Cast icon (usually a rectangle with a Wi-Fi symbol). Tap it, select your TV, and the content plays on the TV while your phone acts as a remote. This method works well for specific apps but does not mirror your entire phone screen the way SmartThings does.

Some Samsung phones also support AirPlay if you are connecting to an Apple TV or an AirPlay-compatible display. The process is the same as SmartThings: open Quick Settings, look for AirPlay, and select your device. AirPlay is less common on Samsung devices than on iPhones, so check your phone's Quick Settings to see if the option is available.

For most situations, SmartThings or Miracast is simpler and more reliable than app-specific casting. Use Cast or AirPlay when you want to stream a single app or video without mirroring your entire phone, or when your TV does not support SmartThings or Miracast.

Frequently Asked Questions

Do I need to be connected to the internet for mirroring to work?

No. SmartThings and Miracast both work over your local Wi-Fi network without needing an internet connection. As long as your phone and TV are on the same Wi-Fi network (or within range for Miracast), they can connect. However, if you are streaming video or using apps that require internet, you will need internet access for those features.

Can I mirror to a TV that is not on the same Wi-Fi network?

Miracast can work without a shared home network because it uses Wi-Fi Direct, a peer-to-peer connection. SmartThings requires both devices on the same network. If you are at a hotel or office, ask if the TV supports Miracast, or use a casting app like YouTube or Netflix if the TV has those apps built in.

Why does my phone screen show a notification that says "mirroring to [TV name]"?

This notification confirms that mirroring is active and shows which device you are connected to. It stays visible so you remember that your phone screen is being displayed on the TV. You can dismiss it by swiping it away, but mirroring will continue. To stop mirroring, open Quick Settings and disconnect from Smart View or Wireless Display.

Can I use my phone while it is mirrored to the TV?

Yes. Your phone remains fully functional while mirrored. Everything you do on your phone appears on the TV in real time. You can open apps, take photos, answer calls, and use your phone normally. The TV straightforward displays whatever is on your phone screen.

What if the mirroring connection keeps dropping?

Frequent disconnections usually mean weak Wi-Fi signal or interference. Move your phone and TV closer to your router, or move the router away from microwaves and cordless phones that can interfere with Wi-Fi. If your router is far from the TV, consider moving it or using a Wi-Fi extender. Restart both devices and try again. If the problem persists, check that your TV firmware is up to date by going to Settings and looking for a Software Update option.
