Modern Smart TV TVs have become powerful multimedia centers capable of playing content in high definition, such as 4K and even 8K. However, built-in browsers or apps on TVs aren't always convenient for finding content, especially when the video is stored on your smartphone or in the cloud. Wireless data transfer technologies allow for instant access. broadcast an image from your mobile device to the big screen, eliminating the need to copy files or connect cables.
In this article, we'll detail all the current methods for watching videos from your phone on a Samsung TV via Wi-Fi, using the built-in features of Android and iOS operating systems, as well as specialized software. You'll learn about protocols. Miracast And AirPlay 2, which are built into most modern models Samsung, and learn how to set up a stable connection for watching videos without delays and artifacts.
For successful wireless data transfer, it is critical that both devices are on the same local network. If your router supports the following ranges: 2.4 GHz And 5 GHz, it is recommended to use the latter for transmitting heavy video streams in high resolution, as it provides higher bandwidth and lower latency.
Preparing equipment and network
Before you begin setting up the broadcast, you need to make sure that your home network is ready to transmit multimedia traffic. Wireless connection is the foundation for all the technologies discussed, and its instability can lead to interruptions in playback or reduced image quality. Make sure your router supports these standards. Wi-Fi Direct or has current firmware.
A common mistake users make is connecting devices to different guest networks or using signal extenders (repeaters), which create isolated network segments. For device discovery to work correctly, the phone and TV must be in the same broadcast domain. If you have a dual-band router, it's best to connect both devices to the network. 5 GHz.
⚠️ Note: If your router is configured to split the bands (different network names for 2.4 and 5 GHz), make sure your phone and TV are connected to the same access point, otherwise they may not “see” each other.
It's also worth checking the software version on your TV itself. Manufacturers regularly update security protocols and add support for new codecs. To check for updates, go to the menu. Settings → Support → Software UpdateHaving the latest firmware version ensures compatibility with the latest mobile OS versions.
Broadcasting via Smart View for Android
Owners of smartphones based on the operating system Android have a built-in screen mirroring tool that is available in devices Samsung it's called Smart ViewThis technology is based on the standard Miracast and allows high-quality image transmission without the need to install additional software. The connection process is as automated as possible.
To get started, pull down the notification shade on your smartphone and find the icon Smart View or BroadcastOnce the feature is activated, the phone will begin searching for available devices on the network. Your TV should appear on the list. SamsungClick on it, and a connection permission request may appear on the TV screen, which you will need to confirm with the remote.

⚠️ Note: The AirPlay 2 protocol is sensitive to network latency. If video is choppy, try closing background apps on your iPhone that are consuming internet traffic.
A unique feature of AirPlay is the ability to stream video not only via mirroring but also directly from supported apps. In this case, the phone acts as a remote control, and the video stream goes directly from the server to the TV, saving battery life and reducing processor load.
What to do if AirPlay isn't working?
Make sure AP Isolation isn't enabled on your router. This setting prevents devices on the same Wi-Fi network from communicating with each other. Also, try rebooting both your router and TV simultaneously.
Broadcast via the SmartThings app
Company Samsung developed a universal application SmartThings, which serves as a central hub for managing all of the brand's smart devices. It not only allows you to control your TV settings but also mirror your smartphone's screen and play media files stored on your phone. This solution is especially useful if standard methods fail for some reason.
Download and install the application SmartThings from Google Play or the App Store. After signing in to your account Samsung Account The app will automatically find your TV on your local network. Select your TV from the list of devices. In the TV control interface, find the "Cast Screen" button or the media file icon to select a specific video from your gallery.
The advantage of using SmartThings is its expanded control functionality. You can use your phone as a full-fledged touchscreen control panel, enter text from your smartphone's keyboard to search YouTube or the TV's browser, and stream files in various formats that the TV's built-in player may not support.
| Function | Smart View (Android) | AirPlay 2 (iOS) | SmartThings |
|---|---|---|---|
| Connection type | Miracast | Apple Protocol | Proprietary |
| Picture quality | High | Very high | Depends on the format |
| Latency | Low | Minimum | Average |
| TV control | Limited | No | Complete |
The app also allows you to create automation scenarios. For example, you can configure it so that when you launch a video player on your phone, the TV automatically turns on and switches to receiving mode. This requires more fine-tuning, but significantly improves user experience.
Playback via DLNA and media servers
If your goal is to watch a movie that is already downloaded to your phone's memory, the most effective way would be to use technology DLNAUnlike mirroring, where the phone encodes the video stream in real time, in DLNA mode, the TV reads the file from the phone itself, acting as a renderer. This reduces the load on the smartphone and often allows for higher bitrate video playback.
On TVs Samsung This function is often called AllShare or simply appears in the signal sources as "Connected device." On your smartphone, you will need a media server app, such as BubbleUPnP, VLC Or use a built-in file manager with DLNA support. In the app, select a video file and set your TV as the playback device.
This method is ideal for watching videos in formats unsupported by streaming services or for browsing personal archives. Image quality is determined by the source file, as no recompression occurs. Audio is also transmitted in its original format, including multichannel tracks.
It's worth noting that Wi-Fi data transfer speeds can vary. If you notice image stuttering when viewing a large file, try moving your phone closer to the router or using a wired connection via a USB-to-Ethernet adapter for your TV if your wireless network is congested.
Third-party apps and browser streaming
In cases where standard tools fail or content needs to be transmitted from a specific source, third-party solutions come to the rescue. Popular streaming services such as YouTube, Netflix, IVi and others have a built-in broadcast button (usually a screen icon with Wi-Fi waves).
