You won't need any extra cables or complicated adapters if your router and TV support Wi-Fi Direct or Miracast. Wireless connection Provides high-resolution image transmission without noticeable delay, which is especially important when viewing dynamic scenes or using a smartphone as a gaming monitor.
In this article, we'll take a detailed look at all available connection methods, from native system functions to third-party apps. You'll learn how to set up data transfer, which video formats are supported, and how to troubleshoot potential network interference.
Preparatory stage: checking device compatibility
Before you begin the setup, you need to make sure that both devices are in the same information space. Local area network — this is the foundation on which the entire data transmission system is built. Make sure your smartphone and TV Samsung connected to the same router.
A common mistake users make is connecting one device to a guest network or the 2.4 GHz band, and another to the main 5 GHz channel. Although modern routers often combine these frequencies under a single name, for stable video transmission, it's better to use the range. 5 GHz.
⚠️ Note: If your router uses AP Isolation, devices on the same network will not be able to see each other. Disable this feature in your router settings.
It's also worth checking the operating system version on your mobile device. For Android, the recommended version is 7.0 and above, and for iOS - iOS 13 or newer to ensure support for current compression codecs.
Using Smart View for Android

☑️ Smart View Pre-Launch Check
If the image quality is poor or the audio is out of sync, try closing background apps on your phone that may be consuming data. Also, ensure the distance between the router and the signal receiver is minimal.
Streaming via Apple AirPlay 2 to iPhone
Smartphone owners iPhone can use the built-in function AirPlay 2, which is supported by Samsung TVs released after 2018. This allows you to stream content in high quality without the need to install third-party apps.
The process of starting a broadcast is intuitive. Open Control center on your iPhone (swipe down from the top right corner or up from the bottom, depending on the model). Tap the button Screen mirroring (two intersecting rectangles).
The system will offer a list of available devices. Select your TV. SamsungIf you're connecting for the first time, a 4-digit code may appear on the TV screen. Enter it on your smartphone for verification.
| Parameter | Description | Requirements |
|---|---|---|
| Protocol | AirPlay 2 | Wi-Fi 802.11ac |
| Permission | Up to 4K HDR | TV support |

| Delay | Minimum | Stable router |
A unique feature of AirPlay is the ability to use your phone while watching. You can minimize an app, reply to a message, or even lock the screen, and video playback on your TV will continue uninterrupted, as long as the source app supports background playback.
What should I do if AirPlay doesn't detect my TV?
Make sure the "AirPlay Access List" option is enabled on your TV in the "General" -> "External Device Settings" menu. Also, try rebooting your router, as the Bonjour protocol used to find devices sometimes requires a network cache refresh.
Stream from YouTube, Netflix, and other apps
The most energy-efficient way to view content is to use the built-in feature Cast (Broadcasting) directly in apps. Unlike screen mirroring, in this case, the phone acts only as a remote control, and the video is loaded directly from the internet by the TV.
To launch, look for the distinctive rectangle icon with Wi-Fi waves in the corner of the video player. Click on it and select your Samsung TVThis method is critical for viewing 4K content, as smartphones are not always capable of decoding and transmitting such a volume of data without loss of quality.
- 🎬 Open the application (YouTube, Netflix, IVI, Okko).
- 📡 Click on the broadcast icon in the player interface.
- 📺 Select a TV from the list.
- ▶️ Playback control (pause, rewind) is carried out from the phone.
The advantage of this method is its autonomy. You can turn off your smartphone's screen, travel to another city (as long as your TV has internet access), or use your phone for other tasks, and your viewing experience will continue uninterrupted.
⚠️ Note: For the Cast function to work, the accounts in the app on your phone and on your TV (if authorization is required) must be active, but do not have to be the same, with the exception of some subscription services.
Third-party apps for advanced features
If standard tools don't work or you need specific features (for example, transferring files of certain formats that aren't natively supported by the TV), third-party solutions come to the rescue. Popular apps like Web Video Caster or TV Cast for Samsung TV allow you to stream video from your browser or local memory.
They often work by emulating the DLNA protocol or creating a local web server on a smartphone. The TV receives a link to the data stream and plays it. This circumvents restrictions on some websites that block standard streaming.
When using such applications, pay attention to access rights. The program may require access to local network and file system. In modern versions of Android (10 and above), these permissions must be granted manually upon first launch.
Some apps allow you to stream not only videos but also photos and music, creating a full-fledged multimedia party. However, be aware that free versions of these programs often contain ads that may appear on your TV screen.
Troubleshooting connection and latency issues
Despite the advancement of technology, users may still encounter issues such as choppy video, out-of-sync audio, or complete failure to detect devices. Most often, the cause lies in radio channel congestion or outdated software.
The first thing you need to do is check for TV firmware updates. Go to the menu Support → Software UpdateManufacturers regularly release patches that improve Wi-Fi module stability and compatibility with new versions of mobile OS.
If the problem persists, try resetting the network settings on both devices. On your router, try changing the broadcast channel to a less congested one (for example, from 1 to 6 or 11 in the 2.4 GHz band) if automatic channel selection fails.
⚠️ Note: The menu interface and item names may vary depending on your Samsung TV model and year. If you don't find an exact match, look for sections related to "Connection," "Network," or "General Settings."
Frequently Asked Questions (FAQ)
Is it possible to stream video without the Internet, only via WiFi?
