Modern technologies make it easy to share content between devices from different manufacturers, turning your smartphone into a powerful multimedia control unit. If you're looking for a way to mirror your phone's content to an LG TV via Wi-Fi using a Samsung smartphone, you've come to the right place. Despite the brands belonging to different ecosystems, wireless data transfer standards ensure high compatibility.
The main task is to choose the right transfer protocol that will be supported by both devices. In most cases, transferring photos, videos, or screen mirroring doesn't require additional cables or expensive adapters. A stable wireless network and basic knowledge of your device's settings are sufficient.
In this guide, we'll take a detailed look at native Android and webOS features, as well as explore proven third-party solutions. You'll learn how to set up a DLNA server, use Miracast technology, and which apps are best for streaming heavy 4K content without lag.
Preparing equipment and setting up the network
The first and most critical step is to ensure a unified network space for both devices. Your smartphone Samsung and TV LG must be connected to the same Wi-Fi network. If you have a dual-band router, make sure both devices are on the same frequency band, preferably 5 GHz, to ensure high throughput.
Check that the software on both devices is up to date. On your LG TV, go to the settings menu and find the system update section to ensure the platform is up to date. webOS Works with the latest security patches and protocol support. A similar action must be performed on the smartphone via the menu. Settings → Software Update.
⚠️ Caution: Using a guest Wi-Fi network or enabling client isolation on your router can completely block devices from discovering each other. Ensure your router settings allow local data transfers between connected devices.
Once connected, check if the devices are visible. LG TVs often require you to activate the function for receiving external connections. This may have different names depending on the firmware version, but it's usually an option. Connecting to a mobile device or a similar item in the general network settings menu.
Using the built-in Smart View feature on Samsung
Smartphones from the South Korean brand Samsung are equipped with a powerful tool for wireless content transfer called Smart ViewThis feature is based on the Miracast standard and allows you to broadcast your screen image in real time. To get started, pull down the notification shade and find the icon. Smart View or Broadcast.
Once activated, your smartphone will begin searching for available receivers on the network. Your TV should appear on the list. LGIf the device is not displayed, make sure the app is running on your TV. Screen Share (on older models) or the function for accepting requests in the connection menu is enabled. When selecting a TV, a confirmation request may appear on the smartphone screen, which must be accepted with the remote control.
- 📱 Open the Quick Settings panel on your Samsung phone by swiping down from the top.
- 📡 Click on the icon Smart View to start a network scan.
- 📺 Select your LG TV from the list of available devices that appears.
- ✅ Confirm the connection on the TV screen if prompted.
It's important to understand that when using Smart View, the image is transmitted in high resolution, but a slight delay in cursor or movement may be observed. This is normal for wireless mirroring technology. Image quality directly depends on the strength of the Wi-Fi signal and the distance from the router.
Stream media via DLNA and Smart Share
If your goal is to play specific video files, photos or music, and not to copy the entire screen, then the technology DLNA It'll work perfectly. LG TVs support this protocol out of the box through a feature that may be called Smart Share or simply appear as a signal source. Samsung smartphones also have built-in support for this standard.
To start the broadcast, open the standard application Gallery or My files on your phone. Select the desired photo or video and press the button Share or the casting icon (a rectangle with waves). Select your LG TV from the list of available devices. The image will instantly appear on the big screen, and your phone will act as a remote control.
The advantage of this method is that the TV decodes the video file itself using its processor, reducing the strain on the smartphone's battery and ensuring smoother playback. However, the file format must be supported by the TV. If the file uses an uncommon codec, streaming may not start.
Third-party apps for advanced features
Sometimes, built-in tools aren't enough, especially when you need to transfer files in specific formats or access the TV's file system. In such cases, third-party apps available in the store come to the rescue. Google PlayOne of the most popular and functional solutions is the application TV Cast for LG TV or Smart View & TV Cast.
These programs work similarly: you install an app on your phone and, in some cases, a companion app on your TV (though many work through the TV's built-in browser). After connecting to the same Wi-Fi network, the app finds the TV by IP address and allows you to stream browser tabs or videos from any online cinemas that don't have a built-in Cast button.
Another powerful tool is AirDroidThis app not only allows you to mirror your screen but also manage files, contacts, and messages directly from your computer or other device, using your TV as a monitor. To use it, you need to register an account and install the app on both devices, or use the web interface.

Troubleshooting connection and visibility issues
Users often encounter a situation where their phone simply doesn't see their TV in the list of available devices. First, check whether guest network mode is enabled on the router for one of the devices. It's also worth rebooting the router, as temporary errors in the ARP table can prevent detection.
If the issue persists, try manually entering the TV's IP address in the streaming app. You can find the IP address in the TV's network settings: Settings → Network → Wi-Fi connection → Advanced settingsSome apps have a "Add device manually" feature where you need to enter these numbers.
