- 🔄 Update your TV firmware through the system settings menu.
- 🔋 Charge both devices to at least 20% to avoid disconnection during the process.
⚠️ Important: If your router broadcasts two networks (2.4 GHz and 5 GHz) with different names, make sure both devices are connected to the same one. Sometimes, separate frequencies can prevent devices from discovering each other.
It's also worth noting that some antivirus programs or router firewall settings can block local data exchange. If you're using a guest Wi-Fi network, it often has client isolation enabled, making it impossible to connect your phone to the TV. In this case, you'll need to switch to the main network.
Using Smart View on Samsung
The main tool for screen sharing on devices Samsung is a function Smart ViewIt's built into the quick settings panel and allows you to easily find available displays within range. This is the most stable method, optimized specifically for the Exynos and Snapdragon processors used in the brand's smartphones.
To launch, pull down the notification shade by swiping down from the top and find the icon Smart ViewIf the icon isn't visible on the first screen, swipe the panel to the right or tap the three dots to edit the list of buttons.

Setting up Samsung SmartThings for control
Application SmartThings is a central hub for smart home control from Samsung and provides advanced TV control options. Unlike simple mirroring, you can use your phone as a remote, transfer files, and even launch apps directly on the TV. This is especially convenient if the remote's keyboard is difficult to enter text on.
To get started, download the app from Google Play or Galaxy Store, if it is not pre-installed. After logging into your account Samsung Account Click the "Add a device" button. The system will prompt you to scan the QR code on the TV screen or search for one automatically on the network. This method provides deeper integration than standard Miracast.
| Function | Smart View | SmartThings | Google Home |
|---|---|---|---|
| Screen mirroring | Yes | Yes | Yes |
| Remote control | No | Yes | Partially |
| File transfer | No | Yes | No |
| Automation | No | Yes | Yes |
Usage SmartThings It allows you to create scenarios, such as automatically turning on your TV when you launch a specific app on your phone. However, keep in mind that initial setup requires more time and registration with the service. For simple video viewing tasks, this method may seem overkill.
What should I do if SmartThings doesn't detect my TV?
If the automatic search doesn't yield results, try adding the device manually by IP address. To do this, in the app, select "Add Device" -> "All Devices" -> "TV" -> "Samsung." You'll need to enter the TV's IP address, which can be found in the TV's network settings under "Network Status."
Streaming via Google Home and Chromecast
Many modern televisions, not even from Samsung, have built-in support for the technology Chromecast built-inThe app is ideal for working with such devices. Google Home, which comes pre-installed on most Android smartphones. This protocol often performs more reliably than native Miracast, especially when streaming videos from YouTube or Netflix.
Open the app Google Home and find your TV in the list of devices. Click on the TV icon, then select the button Broadcast your screenImage quality in this mode is typically higher, and input lag is minimal, which is important not only for video but also for presentations.
It's important to understand the difference between casting a browser tab and the entire screen. When you select a specific app (for example, YouTube), your phone acts only as a remote control, and the TV downloads the video directly from the internet, saving battery life. When you select "Cast Screen," your phone encodes the video stream and sends it to the TV, which can cause the device to heat up.
⚠️ Please note: When using Google Home to mirror your entire screen, audio may be delayed. To watch movies with synchronized audio and video, it's best to play content directly through the app on your TV, using your phone as a remote.
Connecting to TVs with AirPlay 2
New TV models Samsung (2019 series and newer) support the technology AirPlay 2 from AppleWhile the question was about connecting a Samsung phone, it's worth noting that if you have iOS devices in your household, this protocol provides better compatibility. However, Android smartphones can also take advantage of this ecosystem through third-party solutions.
To activate AirPlay on your Samsung TV, go to Settings → General → Apple AirPlay Settings and enable the feature. Make sure your security settings are set to allow connection on the first attempt or require a code to prevent neighbors from mirroring your screen.
- 🍏 AirPlay provides highly stable connections on Apple networks.
- 🔒 End-to-end encryption support protects transmitted data.
- 📱 On Android, special emulator applications are required to use AirPlay.
- 🎮 Low latency makes the protocol suitable for mobile gaming.
If you're using a Samsung phone, there's no direct AirPlay support natively, but you can stream content that supports this standard through compatible apps. Android users should generally use the standard Cast or Miracast protocols, which perform faster on heterogeneous networks.
Solution and troubleshooting
Even with proper setup, situations may arise where the phone doesn't detect the TV or the connection constantly drops. Most often, the problem lies in energy saving settings or IP address conflicts. Restarting the router and both devices resolves 80% of these issues.
Check if your TV has a time limit or parental controls that block new connections. Also, make sure location access is enabled in the system service permissions on your smartphone, as Android requires this for the Wi-Fi scanner to function.
⚠️ Note: Menu interfaces and item names may differ depending on the Tizen OS version on your TV and the Android/One UI version on your phone. If you don't find an exact match, look for similar sections in the network or connection settings.
If the image is choppy or has low resolution, check the Wi-Fi bandwidth. Simultaneous downloads of large files by other devices can choke the video data stream. In this case, it's recommended to use the 5 GHz band, which is less congested and has higher throughput.
