Modern multimedia capabilities make it possible to transform any TV into a full-fledged home entertainment center, and pairing a Samsung smartphone with a Sony TV is one of the most popular and functional. Wireless connection Wi-Fi frees users from unnecessary wires and gives them the freedom to move around the room while watching a video or presenting. This data transfer technology not only allows for screen mirroring but also streaming content from specific apps, ensuring high-quality image and sound.
For successful synchronization of devices, it is important that both gadgets work in a single local network, which is a fundamental requirement for most media transmission protocols. Equipment owners Samsung And Sony can use several connection methods, each of which has its own characteristics and usage scenarios. The DLNA protocol ensures stable file transfer, while Miracast and AirPlay 2 allow you to mirror your screen in real time.
In this article, we'll take a detailed look at all available connection methods, from built-in Android operating system features to specialized manufacturer apps. You'll learn how to set up Smart ViewHow to use standards Google Cast And what to do if devices don't see each other in the list of available receivers. Proper network configuration and understanding of protocol principles will help avoid delays and audio desynchronization.
Equipment preparation and network requirements
Before you begin setup, you need to make sure your equipment meets the minimum technical requirements for stable operation of wireless protocols. Both devices—and your smartphone— Samsung Galaxy, and TV Sony Bravia — must support the 802.11n WiFi standard or higher, as older protocol versions may not provide sufficient throughput for high-definition video streaming. It is also critical that the router is functioning correctly and does not block data exchange between connected clients.
Make sure the software on both devices is updated to the latest available version. On Sony TVs, you can check this in the Settings → System → About TV → System software updateOn Samsung smartphones the path usually looks like this Settings → Software Update → Download and InstallAvailability of current drivers and system libraries guarantees compatibility with the latest codecs and security protocols.
⚠️ Important: If your router supports splitting frequencies into 2.4 GHz and 5 GHz with different network names (SSIDs), make sure your phone and TV are connected to the same frequency. In some cases, client isolation at the router level can prevent devices from discovering each other.
Check your mobile device's battery or connect it to a power source, as transmitting a video stream over WiFi consumes a significant amount of power. Watching high-definition movies for extended periods can quickly drain the battery, interrupting your session at the most inopportune moment. Mains power stability also impacts WiFi performance, preventing sudden connection interruptions.
Screen Mirroring (Miracast) method for screen duplication
Technology Miracast, known on Samsung devices as Smart View, is the most versatile way to fully mirror your smartphone's screen to your TV. This method creates a direct WiFi connection between devices (WiFi Direct technology), allowing you to stream images even without an active internet connection, as long as both devices are nearby. To start using it, press the button labeled MIRRORING or go to the signal sources menu and select the appropriate item.
On a Samsung smartphone, you need to expand the quick settings panel by swiping down from the top and find the icon Smart ViewOnce activated, the system will begin searching for available displays within range. When your Sony TV appears in the list (the model may be displayed as Bravia (or have a room name if one was previously set), tap its name to initiate the connection. A confirmation prompt may appear on the TV screen, which you'll need to accept with the remote.
☑️ Check before connecting Miracast
Picture quality when using Miracast The image quality directly depends on the WiFi signal strength and the airwaves' congestion. Some cursor or audio lag is possible, which is normal for wireless real-time video streaming. If the image is choppy, try moving your phone closer to the router or TV, or reduce the network load by disabling other active downloads.
Why might screen mirroring not work?
This feature may not be available if an app using protected content (DRM) is running on the TV, or if the Android version on the phone is too old to support a specific Miracast codec. Antivirus software with a network protection feature may also cause the issue.
Using Chromecast Built-in and Google Home
Sony TVs often run on the Android TV or Google TV operating system, meaning they have built-in support for the technology. Google Cast (Chromecast built-in). This is the preferred method for watching videos from internet services like YouTube, Netflix, or online movie theaters, as the phone only acts as a remote control, and the data stream goes directly from the server to the TV via WiFi.
To implement this method, make sure that you have the app installed on your Samsung Google HomeOpen it and find your TV in the list of devices. If you want to cast a Chrome browser tab or the screen of apps that don't have their own Casts button, select the device in the app and click the button. Broadcast your screenThis method often provides a more stable image and puts less strain on the smartphone's battery compared to Miracast.
In video player apps, look for the distinctive rectangle icon with WiFi waves in the corner. Tapping it will display a list of available devices. Select yours. Sony Bravia, and the video will play on the big screen, allowing you to use your phone for other tasks or lock it to save battery.

Stream via DLNA and the Video & TV SideView app
Protocol DLNA (Digital Living Network Alliance) is a classic standard for transmitting media content (photos, videos, music) over a local network. Unlike screen mirroring, the phone scans the internal memory for media files and sends them to the TV for playback. Samsung users can use the standard app for this. Gallery or My files, by selecting the option Broadcast in the menu.
Sony has developed its own application Video & TV SideView, which significantly expands interaction capabilities. It allows you to not only stream content, but also control your TV, receive information about broadcast programs, and even transfer playback from your mobile device to your TV with a single touch. Download the app from Google Play Store and follow the pairing instructions by scanning the QR code on your TV screen or entering the code manually.
⚠️ Note: App interfaces and feature names may vary depending on the Android TV operating system version and the model year of your Sony TV. If you don't see the described options, check the "Apps" section on your TV—some features may be organized into separate modules.
When using DLNA, it's important to consider the file format. Sony TVs support most popular codecs, such as MP4, MKV, AVI, but they may not play videos with non-standard bitrates or rare audio tracks without re-encoding. If you experience playback issues, try using third-party players on your phone, such as VLC for Android, which have built-in DLNA servers and can stream almost any format.
Solution and troubleshooting
Despite the simplicity of setup, users may encounter a situation where the phone doesn't detect the TV or the connection constantly drops. First, check the firewall or antivirus settings on the router, which may be blocking local data exchange between devices from different manufacturers. Sometimes, simply rebooting the router and both connected devices, which clears the network settings cache, helps.
If the image is transmitted, but the sound is missing or out of sync, try changing the audio output settings in the TV menu.
