Preparing equipment and network
Before you begin setup, make sure your Samsung TV is connected to the internet. The model must support the technology. Smart Hub or Tizen OSOlder models without smart features may not support wireless image transmission.
⚠️ Important: Make sure your router is broadcasting at 5GHz to minimize latency when streaming high-definition video.
The smartphone must also be connected to the same access point as the TV. If you plan to use Wi-Fi DirectInternet access on the router may not be required, but both devices must support this protocol. Make sure both devices have the latest software updates.
For stable operation, we recommend disabling VPN services on your phone, as they can block local device discovery on the network. You should also temporarily pause large file downloads on other devices to avoid overloading your bandwidth.
Using Smart View on Android
Owners of Samsung smartphones and many devices based on Android have access to the function Smart ViewThis technology allows you to mirror your phone's screen to your TV without installing additional software.
To launch, open the Quick Settings panel by swiping down from the top. Find the icon Smart View or "Broadcast." The system will begin searching for available displays within range.
☑️ Check before connection
Once your Samsung TV appears in the list, tap it. You may see a connection permission prompt on the TV screen—confirm it with the remote. After that, the image from your phone will be mirrored to the big screen.
The feature supports aspect ratio adjustment and playback controls. You can minimize the app on your phone, and the video will continue playing on your TV, allowing you to answer calls or chat on messengers.
Stream from iPhone via AirPlay 2
Modern Samsung TVs support the technology AirPlay 2, developed by Apple. It allows iPhone and iPad owners to stream content directly through the system's Screen Mirroring menu.
Make sure AirPlay support is enabled on your TV. To do this, go to Settings → General → Apple AirPlay Settings and activate the function. If the option is missing, your TV firmware may need to be updated.
| Parameter | Requirement | Note |
|---|---|---|
| iOS version | 12.3 and above | The latest version is recommended |
| TV model | Samsung 2018+ | Q, N, M series and newer |
| Net | Same Wi-Fi | 5 GHz band is preferred |
| Codec | H.264 / HEVC | Hardware acceleration |
Open Control Center on your iPhone (swipe down from the upper-right corner or up from the bottom on older models). Tap the Mirroring button (two rectangles). Select your TV from the list.
If this is your first time connecting, a four-digit code will appear on the TV screen. Enter it on your iPhone to confirm the pairing. After that, the screens will sync, and you can share photos, videos, or games.
Samsung SmartThings app
For deeper control and customization, the universal solution is the application SmartThingsIt's available for Android and iOS and turns your smartphone into a universal remote control with advanced features.
Download the app from Google Play or App Store and sign in to your Samsung account. The app will automatically find the TV on your local network. Once the device is added, you'll have access to the settings menu and gallery.
What should I do if the app doesn't detect the TV?
Make sure the same Samsung Account is used on both your phone and TV. Also, check that your antivirus or router firewall isn't blocking local discovery protocol ports. Restarting the router can sometimes help.
In the app interface, select your TV and tap the "Screen Casting" button or the three-dot icon to open the menu. This not only allows you to mirror your screen but also upload files from your phone to your TV for playback.
SmartThings also lets you create automation scenarios. For example, when you start a YouTube video, your phone can automatically suggest displaying the video on your TV if you're at home.
Broadcasting from browsers and applications
Many users want to display a specific video from a browser or streaming service, rather than the entire phone screen. This technology is used for this purpose. Cast (formerly Chromecast built-in) or DLNA.
In the browser Google Chrome or Samsung Internet Open the video you want. Click the menu (three dots) and select "Stream" or the rectangle icon with waves. Select the target device.
- 📺 YouTube: Click the broadcast icon in the corner of the video player.
- 🎬 Netflix: Only available if the TV app supports this content.
- 🌐 Browser: Broadcasts the entire tab, including sound.
This method is the most energy-efficient, as the TV itself downloads the data stream, offloading the smartphone's processor. You can lock your phone's screen or use it for other tasks while the video plays on the big screen.
⚠️ Note: Some streaming services (e.g., Netflix, Disney+) block image output via simple screen mirroring due to HDCP copy protection. Use the built-in Cast button within the app.
Troubleshooting connection issues
If your TV doesn't appear in the list of available devices, try rebooting your router. This is often due to a temporary DHCP server outage or an IP address conflict on your local network.
Check your router's firewall settings. Function AP Isolation (Access Point Isolation) prevents devices within the network from seeing each other. It must be disabled in the Wi-Fi router settings.
Make sure the date and time on your TV and phone are synchronized. Time differences can cause security certificate errors when attempting a secure connection.
In rare cases, resetting the network settings on your TV can help. Go to Settings → General → Network → Reset network settingsAfter this, you will need to re-enter your Wi-Fi password.
Frequently Asked Questions (FAQ)
Is it possible to connect a phone to a Samsung TV without the Internet?
Yes, it's possible. Use Wi-Fi Direct to mirror your screen or connect your phone to the TV's own hotspot (if the model supports Mobile Connect). This option eliminates the need for an external internet connection; it creates a local network between the devices.
Why is the video lagging during broadcasting?
Lag is most often caused by a weak Wi-Fi signal or channel congestion. Move closer to the router, disable downloads on other devices, or switch the router to the 5 GHz band, which is less congested and ensures faster data transfer.
Does my old Samsung TV support wireless streaming?
Models released before 2016 may not have built-in AirPlay 2 or modern Smart View support. In this case, external adapters, such as Chromecast or Miracast receivers, connected via HDMI, can be used.
How do I mute my phone when broadcasting on TV?
When using Screen Mirroring, audio is usually mirrored automatically. If audio is only coming from your phone, check the volume settings in the casting menu on your smartphone or select your TV as the audio output device in the Bluetooth/Media Devices settings.
