- 🔒 When connecting for the first time, a permission request may appear on the TV screen, which you will need to confirm with the remote control.
- 📉 Image quality may decrease with a poor Wi-Fi signal due to video stream compression.
Broadcast via the Samsung SmartThings app
For deeper integration and content management, the company Samsung developed an official application SmartThingsThis software is available for platforms Android And iOS and provides advanced capabilities compared to simple screen mirroring.
After installing the app and logging in to your Samsung Account, you need to add a TV. The app will automatically scan the network and offer to connect to the detected TV. Once paired, the smartphone turns into a powerful remote control with media streaming capabilities.
To cast a video, open the app, select your TV, and press the "Cast" button (the screen icon with an arrow). In the menu that opens, you can select "Photos & Videos" to access your gallery or "Videos" to play files directly. This method often provides better stability as it uses optimized transfer protocols.
⚠️ Note: The SmartThings app interface may vary depending on your phone's operating system version and region. Some features may not be available on older TV models.
A unique feature of this method is the ability to use the phone for other tasks while the video is playing on the TV, if the content is downloaded from the cloud or an online service, rather than transmitted directly from the device's memory in real time.
Using DLNA technology and built-in players
Protocol DLNA (Digital Living Network Alliance) is a standard for multimedia transmission over a local network. It allows files to be streamed directly, without burdening the phone's processor with constant video encoding, thereby saving battery life.
Many video players on Android, such as VLC for Android or MX Player, have built-in DLNA support. After opening a video file in the player, click the image output button (usually a screen icon with waves) and select the TV. Samsung from the list of available renders.
You don't need to press anything on the TV if it's on. The TV will receive the playback command and download the file over the network automatically. This is especially convenient for viewing large, high-quality files where smooth playback is essential.
| Parameter | Screen Mirroring | DLNA / Player | SmartThings |
|---|---|---|---|
| Phone CPU usage | High | Low | Average |
| Ability to turn off the phone screen | No (the screen is on) | Yes | Yes (partially) |
| Picture quality | Depends on the signal | Original (no loss) | High |
| Playback controls | From the phone | From the phone | From the phone and remote control |
Why does video lag when using DLNA?
Slowdowns may occur if the router cannot handle the data flow or if the video file has a bit rate that is too high, exceeding the current Wi-Fi channel bandwidth.
Broadcasting from browsers and online services
Popular streaming services such as YouTube, Netflix or IVi, use their own transmission mechanism based on protocols Google Cast or native Smart TV apps. This is the most convenient way to watch online content.
In the YouTube app on your phone, tap the cast icon (the rectangle with Wi-Fi waves) in the corner of the video player. Select your TV from the list of devices. SamsungThe video will start playing on the big screen, and your phone will act as a remote control.

- 🌐 Make sure your phone and TV accounts are synced for quick access to your history.
- 📺 To work, you need the YouTube app (or another service) installed on the TV itself.
- 🔋 This method uses minimal battery power on your smartphone.
Troubleshooting and troubleshooting
Despite the technology's maturity, users may encounter difficulties. If the TV doesn't detect the phone, first check the firewall settings on the router. Sometimes antivirus software or network security settings block the ports required for discovery protocols.
Another common issue is audio/video desynchronization. This can often be resolved by adjusting the sound settings in the TV menu. Try switching the sound mode from "Adaptive" to "Standard" or "Optimized."
⚠️ Note: If you use a VPN on your smartphone, your local network may become unavailable to other devices. Disable your VPN before attempting to connect to your TV.
If you experience frequent connection drops, try statically assigning IP addresses for your TV and phone in your router settings. This will prevent addressing conflicts if your router's DHCP server is unstable.
Frequently Asked Questions (FAQ)
Is it possible to transfer video to a Samsung TV without the Internet, only via Wi-Fi?
Yes, you can. Screen Mirroring and Wi-Fi Direct technologies create a direct connection between devices or use the router's local network without accessing the external network. Internet access is only required to download online content, not to transmit the signal from the phone to the TV.
Why does the sound come from the phone and not the TV when streaming video?
It depends on the method you choose. When using DLNA or YouTube, the audio should come from the TV. If you use simple screen mirroring on some Android models, the audio may remain on the phone. Check the audio output settings in the phone's quick menu.
Do older Samsung TVs support Wi-Fi video streaming?
Smart TV models released before 2015-2016 may not support modern AirPlay 2 protocols or have file format limitations. For these models, the only viable option is often to use DLNA servers or external set-top boxes.
How can I improve image quality if my video is constantly buffering?
Try lowering the playback resolution in the source app settings. Moving the router closer to the TV or switching to the 5 GHz frequency if the router is dual-band may also help. Closing background apps on your phone may also help.
