Modern technologies make it possible to completely eliminate unnecessary cables, turning gadgets into a single multimedia center. Wireless connection has become the standard for streaming photos, videos, and games to the big screen. If you own a device from the Korean giant, the syncing process usually takes just a couple of minutes with the right approach.
In this article, we will examine in detail all the available methods, from built-in functions Smart View to third-party apps. You'll learn how to ensure stable high-definition data transmission and what to do if devices stop communicating with each other on your home network.
First of all, you need to make sure that your equipment is ready to work. Wi-Fi router must support 802.11n standards or higher, and both devices must be on the same local network. This is a fundamental requirement for any wireless media transmission technology.
Preparatory stage and network requirements
Connection stability directly depends on signal quality and router settings. To transmit video in 4K resolution It's recommended to use the 5 GHz band, which is less congested and provides higher throughput. However, older TV models can only operate on the 2.4 GHz frequency.
Check if the feature is enabled Wi-Fi Direct in your router settings, although this isn't necessary for most modern methods. The main thing is that your phone and Samsung TV receive IP addresses from the same device.
It's also worth updating the software on both devices. On TVs Samsung This is done through the support menu, and on a smartphone, through the system settings. Outdated Wi-Fi module drivers often cause connection interruptions.
- 📶 Make sure both devices are connected to the same Wi-Fi network (not a guest network).
- 🔄 Update your TV's firmware via the menu
Support → Software Update. - 📱 Check if Bluetooth is enabled on your phone (needed for initial pairing).
- ⚡ Connect the TV directly to the power supply, avoid using cheap extension cords.
Using Smart View on Android

⚠️ Note: When connecting for the first time, a permission request may appear on the TV screen. You must confirm this permission using the remote control within 30 seconds, otherwise the connection will be reset.
Once paired successfully, the image from your phone will appear full-screen. You can minimize the app on your smartphone and continue using it while the video plays on your TV. This is especially convenient for watching content from browsers or streaming services.
The feature supports playback control directly from the lock screen or via a widget. You can also change permission and aspect ratio if the image appears stretched. To do this, click the three dots in the Smart View menu and select the appropriate settings.
Stream from iPhone via AirPlay 2
Apple device owners can use the built-in function AirPlay 2, which is supported by Samsung TVs released after 2018. This ensures high-quality video and audio transmission with minimal latency.
Open the Control Center on your iPhone (swipe down from the upper-right corner or swipe up on older models). Tap the button Screen mirroring and select your TV SamsungIn some cases, you will need to enter the code displayed on the TV screen.
If your TV doesn't appear in the list, check your privacy settings. On your TV, go to Settings → General → Apple AirPlay Settings and make sure the feature is enabled. You can also set up a password requirement for new devices for security.
- 🍏 Make sure your iOS is updated to the latest version.
- 📺 Enable AirPlay support in your TV settings.
- 🔒 When prompted, enter the 4-digit code shown on the TV screen.
- 📶 For 4K video, use a 5GHz network to avoid buffering.
The technology not only mirrors your screen but also streams content from specific apps, such as YouTube or Netflix, in high quality. In this case, the phone acts as a remote control, and the video is loaded directly by the TV, saving battery life.
Samsung SmartThings app for control
The universal tool for the ecosystem is the application SmartThingsIt's available for both Android and iOS and allows you to not only stream images but also fully control your TV from your smartphone.
After installing the app and signing in to your Samsung account, click the "Add Device" button. The system will find the TV on your local network. Once paired, you'll gain access to the virtual remote and file transfer capabilities.
☑️ Setting up SmartThings
In the section Gallery or Media Within the app, you can select photos or videos and send them to the big screen. The interface allows you to create slideshows or play video files, supporting various codec formats.
One of the key features is the ability to use your smartphone as a touchpad. You can move your finger across the phone's screen to move the cursor on the TV, making it convenient for entering text while searching for content.
| Function | Smart View | SmartThings | AirPlay 2 |
|---|---|---|---|
| Screen mirroring | Yes | No (media only) | Yes |
| TV control | Limited | Complete | Minimum |
| Platform | Android | Android / iOS | iOS |
| Sound quality | Standard | Depends on the file | High |
DLNA technology and media playback
If your goal is to view photos or videos stored in your phone's memory, you can use the protocol DLNAThis method does not duplicate the screen, but transmits the media file itself for decoding by the TV.
Many video players on Android, for example, VLC for Android or BubbleUPnP, have built-in DLNA support. Open the file in the player, press the cast button, and select your Samsung TV.
The advantage of this method is that the phone doesn't waste resources rendering images. You can turn off your smartphone's screen or play other demanding games, and the video will play on your TV without any lag.
Why does the sound disappear during broadcasting?
This is often due to content DRM restrictions (for example, Netflix or HBO). In such cases, the app blocks wireless audio or video transmission, requiring the use of official apps on Smart TVs.
DLNA data transfer speed depends on the strength of the Wi-Fi signal. For large uncompressed files (e.g., ISO disk images), a wired connection or a local server is recommended, but Wi-Fi is sufficient for most tasks.
Troubleshooting connection and visibility issues
Sometimes it happens that the TV simply doesn't detect the phone, or the connection constantly drops. Most often, the problem lies in the router's security settings or the network service cache.
Try rebooting your router by completely unplugging it for 10-15 seconds. This will clear the ARP table and assign new IP addresses to devices, which often resolves the "invisibility" issue.
⚠️ Note: Antivirus software and firewalls on smartphones can block local connections. If nothing helps, try temporarily disabling network protection on your phone to check.
Also check if the function is enabled on your router AP Isolation (Access Point Isolation). When enabled, devices on the network are prevented from communicating with each other, making wireless synchronization impossible.
- 🔄 Restart the router and both connected devices.
- 📡 Check if AP Isolation is enabled on your router.
- 📶 Make sure your phone and TV are on the same band (2.4 or 5 GHz) if your router separates the networks.
- 🗑️ Clear the cache of the Smart View or SmartThings app in Android settings.
In rare cases, resetting the network settings on your TV can help. To do this, go to Settings → General → Network → Network ResetAfter this, you will need to re-enter your Wi-Fi password.

Why does the image jerk when streaming video from my phone?
This is a sign of low channel bandwidth or interference. Try moving closer to the router, disabling downloads on other devices, or switching to the 5 GHz band. Reducing the streaming quality in the app settings may also help.
Does the connection work if the mobile Internet is turned off on the phone?
Yes, mobile internet (3G/4G/5G) is not required for Wi-Fi Direct and local data transfer to work. The only requirement is that the Wi-Fi module is working and the devices are connected to the same local network.
How do I mute my phone so it only plays on the TV?
When using Smart View, the sound usually switches automatically to the TV. If this doesn't happen, turn the volume down on your phone. Some Samsung models have a separate media volume slider in the Smart View menu.
