Modern technology allows you to transform your TV into a full-fledged multimedia center, but the question often arises of how to stream content from a mobile device to the big screen. Samsung Galaxy And LG Smart TV Both manufacturers are in an advantageous position, as they are actively implementing wireless data transmission standards. Wi-Fi connectivity eliminates the need for adapters, HDMI cables, and tangled wires, ensuring high image quality.
There are several proven ways to establish communication between gadgets, and the choice of a specific method depends on the year of manufacture of your device and the version of the operating system. The main protocols include a built-in function Screen Share, technology Miracast, as well as support AirPlay 2 on new LG models. We'll examine each option in detail so you can choose the most stable and convenient one for your situation.
Before setting up, make sure both devices—your smartphone and TV—are connected to the same wireless network. This is a fundamental requirement for most streaming protocols to work, as data transfer occurs through a local router. If you ignore this, the devices simply won't see each other in the list of devices available for connection.
Preparing equipment and updating software
The first step before starting setup is to ensure the software on both devices is up to date. Manufacturers regularly release updates that fix connection issues and add support for new codecs or security standards. On the TV LG This can be done by going to the settings menu and selecting the "About TV" or "Support" section, where the check for updates button is located.
On a smartphone Samsung The procedure is similar: go to system settings and select "Software Update." If new firmware versions are available, be sure to install them. Connection issues are often caused by incompatibility between DLNA or Miracast protocol versions on older software versions.
⚠️ Please note: If your LG TV is more than 10 years old and uses the older NetCast platform, modern wireless streaming methods may not be available. In this case, you will need to use external adapters.
It's also worth rebooting your router if it's been running for a long time without being turned off. A clogged router cache can cause connection interruptions when transmitting heavy, high-definition video streams. Simply turning the power off for 10-15 seconds often resolves connection stability issues.
☑️ Check before connection
Using LG's built-in Screen Share feature
The most native way for LG TVs is to use technology Screen Share, which is based on the Miracast standard. This method allows you to mirror your Samsung smartphone's screen to your LG TV in real time without the delays typical of some third-party apps. To get started, press the button labeled Input or select the icon in the application launcher menu Screen Share.
Once the feature is activated, a message will appear on the TV screen indicating that it's waiting for a connection. At this point, the TV will either create a direct Wi-Fi connection or become visible to other devices on the local network. On a Samsung phone, pull down the notification shade and find the button. Smart ViewIn older models, this feature may be called "Broadcast" or "Screen Mirroring".

It's important to note that when using Screen Share, your phone's screen stays on, and you can control playback directly from the touchscreen. However, this mode drains your smartphone's battery significantly faster due to the Wi-Fi module and processor being active.
AirPlay 2 streaming for new LG models
Owners of modern LG TVs (2019 models and newer) have access to technology AirPlay 2, developed by Apple but now available for Android devices via compatible apps or native Samsung features. This protocol provides a more stable connection and better image quality than classic Miracast.
To activate AirPlay on your LG TV, go to Settings → Connection → AirPlay and make sure the feature is enabled. On a Samsung phone, the process is similar to the previous method: through the Quick Settings panel. Smart View You select your TV. The system will automatically detect the supported protocol and switch to AirPlay if it provides better performance.
The advantage of this method is that you can use your phone for other tasks without interrupting the video stream, if the app supports this mode. AirPlay 2 also handles buffering better, reducing image tearing when watching fast-moving scenes.
| Characteristic | Screen Share (Miracast) | AirPlay 2 | Applications (YouTube) |
|---|---|---|---|
| Image lag | Minimum | Low | Absent |
| Battery consumption | High | Average | Short |
| Video quality | Depends on the signal | Stable HD/4K | Maximum |
| Background mode | No (duplication) | Partially | Yes |
If you plan to use casting frequently, it's a good idea to pin the Smart View widget to your Samsung home screen for quick access. This will save time each time you connect.
The official LG TV Plus app
LG has developed its own app LG TV Plus, which is available in the Google Play Market. This versatile tool allows you to not only stream images but also use your phone as a remote control and transfer files. After installing the app on your Samsung smartphone, you need to launch it and go through the initial setup.
