The fastest way to mirror an iPhone to a Samsung TV

You can mirror an iPhone to a Samsung TV using SmartThings, Samsung's built-in wireless casting system, or through AirPlay if your Samsung TV supports it. The SmartThings method works on most Samsung TVs made in the last five years and requires no extra apps or cables — just both devices on the same Wi-Fi network.

The process takes about 30 seconds once you know the steps. Your iPhone screen will appear on the TV in real time, and you can control what displays from your phone. Audio plays through the TV speakers unless you change the output in your iPhone settings.

Key Takeaways

  • SmartThings is the most direct method for Samsung TVs and works wirelessly without needing AirPlay support.
  • Both your iPhone and Samsung TV must be connected to the same Wi-Fi network before you start.
  • AirPlay mirroring works on newer Samsung TVs (2018 and later) if you enable it in the TV settings first.
  • If wireless mirroring fails, an HDMI adapter connected to your iPhone can display your screen as a backup option.

Mirror using SmartThings on your Samsung TV

Open the SmartThings app on your iPhone. If you do not have it, read it from the App Store. Tap the Devices tab at the bottom, then tap the plus icon to add a device. Select TV from the list, then choose your Samsung TV from the available devices. Your TV will ask you to confirm the connection — select Allow on the TV remote.

Once your TV is added to SmartThings, go back to the Devices tab and tap your TV. Look for the Mirror or Screen Mirroring button — it usually appears as a rectangle with a curved arrow. Tap it, and your iPhone screen will appear on the TV within a few seconds. To stop mirroring, tap the Mirror button again or swipe up from the bottom of your iPhone to open Control Center and tap Screen Mirroring, then select Stop Mirroring.

SmartThings works best when your TV is on the same Wi-Fi network as your phone. If your TV does not appear in the app, restart both devices and make sure they are on the same network. Some older Samsung models may not support SmartThings mirroring — check your TV's manual or settings menu to confirm.

Use AirPlay if your Samsung TV supports it

Newer Samsung TVs (2018 and later) have built-in AirPlay support. To use it, first enable AirPlay on your TV: press the Menu button on your remote, go to General, then Apple AirPlay Settings, and turn it On. Make sure your TV and iPhone are on the same Wi-Fi network.

On your iPhone, swipe down from the top-right corner to open Control Center. Tap Screen Mirroring, then select your Samsung TV from the list. Your iPhone will ask you to enter a four-digit code that appears on the TV — type it in, and mirroring will start. To disconnect, open Control Center again and tap Stop Mirroring.

AirPlay is more reliable than SmartThings on compatible TVs because it is Apple's native standard. If your Samsung TV does not show AirPlay in the settings menu, it likely does not support the feature — use SmartThings instead.

Connect with an HDMI adapter if wireless fails

If neither SmartThings nor AirPlay works, you can use a wired connection. Buy a USB-C to HDMI adapter (if your iPhone has USB-C) or a Lightning to HDMI adapter (for older iPhones). Plug the adapter into your iPhone, connect an HDMI cable to the adapter, and plug the other end into your TV's HDMI port.

Switch your TV to the correct HDMI input using the remote. Your iPhone screen will display on the TV when ready. This method does not require Wi-Fi and works on all Samsung TVs with an HDMI port. The downside is that your iPhone stays tethered to the TV, so you cannot move around the room.

Wired adapters cost between $15 and $40 depending on the brand. Apple's official adapters are more expensive but tend to be more reliable. Third-party options from Anker or Belkin work well for most people and cost less.

Troubleshoot when mirroring does not start

If your iPhone does not find your TV, restart both devices and check that they are on the same Wi-Fi network. Open your iPhone Settings, go to Wi-Fi, and confirm the network name. Then check your TV settings to see which network it is connected to — they must match. If they do not, reconnect your TV to the correct network using the remote.

If SmartThings shows your TV but mirroring fails, try removing the TV from the app and adding it again. Go to SmartThings, tap Devices, find your TV, tap the three dots, and select Remove Device. Then add it again using the plus icon. This usually fixes connection problems.

If AirPlay is enabled on your TV but does not appear on your iPhone, restart your TV by unplugging it for 10 seconds, then plugging it back in. Some Samsung models need a firmware update to support AirPlay — check the TV settings under Support or About This TV to see if an update is available.

What to expect when mirroring is active

When your iPhone is mirrored to the TV, everything on your phone screen appears on the TV in real time. This includes apps, web pages, photos, and videos. The TV will also display any notifications that pop up on your phone. Audio from your iPhone plays through the TV speakers by default, but you can change this in your iPhone settings if you want sound to come from your phone instead.

Mirroring uses Wi-Fi bandwidth, so your internet speed may slow slightly if other devices are streaming. The connection is usually stable, but if your Wi-Fi signal is weak, the picture may lag or drop. Moving closer to your router or reducing the number of devices on your network can help.

Battery drain is noticeable when mirroring — your iPhone will use more power than normal. If you plan to mirror for more than an hour, plug your phone into a charger. Wired HDMI connections do not drain the battery as quickly as wireless methods.

Frequently Asked Questions

Can I mirror my iPhone to a Samsung TV without Wi-Fi?

No, SmartThings and AirPlay both require Wi-Fi. A wired HDMI adapter is your only option if you do not have Wi-Fi. The adapter connects directly to your iPhone and TV, so no network is needed.

Will mirroring work if my Samsung TV is older than 2018?

SmartThings mirroring works on most Samsung TVs from 2015 onward. AirPlay only works on 2018 models and newer. If neither works, use an HDMI adapter. Check your TV's manual or model number to confirm which features it supports.

Can I use my iPhone while mirroring?

Yes. You can open apps, take photos, or browse the web on your iPhone while mirroring, and everything will display on the TV. You can also lock your iPhone screen and the TV will show a black screen, but the connection stays active.

Why does my screen keep disconnecting from the TV?

Weak Wi-Fi is the most common cause. Move your phone closer to the router or restart your router. If the problem continues, try removing the TV from SmartThings and adding it again. Interference from other devices on the network can also cause drops — try mirroring at a different time to see if it is more stable.

Do I need to buy anything to mirror my iPhone to a Samsung TV?

No, if your TV supports SmartThings or AirPlay. Both are free and built in. If you want to use a wired connection, you will need to buy an HDMI adapter, which costs $15 to $40.
