Modern smartphones Huawei and televisions Samsung They offer a wide range of features that allow you to turn your gadget into a powerful multimedia center. Users often look for a way to display images from a small screen on a larger panel without the need for unnecessary wires. This is especially important when viewing movies, photos, or presentations, where image quality and size are crucial. Wireless connection via Wi-Fi is the most convenient and popular method for implementing such a task.
In this article, we'll take a detailed look at all the available methods for synchronizing devices, from built-in operating system features to specialized apps. You'll learn how to set up Wi-Fi Direct, use the protocol Miracast and what nuances exist between different firmware versions. Proper configuration will ensure stable, high-definition video streaming without lag.
Before setting up, make sure both devices are working properly and have access to a power source. The connection process typically takes no more than a few minutes if all technical requirements are met. We'll cover both built-in tools and third-party solutions for situations where standard methods don't work.
Preparing equipment and network
The first and most important step is ensuring a stable connection. To successfully transmit a high-definition video signal, both devices need to be on the same local network. This means your smartphone Huawei and TV Samsung must be connected to the same router. If you are using a range 5 GHz, the data transfer speed will be significantly higher, which is critical for watching 4K video.
Make sure the software on both devices is up to date. Manufacturers regularly release updates that fix wireless protocol bugs and add support for new codecs. On your TV, you can do this through the menu. Settings → Support → Software UpdateOn a smartphone, the path usually looks like this: Settings → System and updates → Software update.
⚠️ Note: If your router supports splitting the 2.4GHz and 5GHz bands into different SSIDs (network names), make sure both devices are connected to the same frequency, preferably 5GHz for best performance.
It's also worth considering the distance between the gadget and the TV. Although Wi-Fi has a long range, it's best to be in the same room for initial pairing and a stable connection. Obstacles such as walls or household appliances can cause interference, especially in apartment buildings with many neighboring networks.
Using Smart View on Huawei
Smartphones Huawei, working on the shell EMUI or Magic UI, are equipped with a built-in wireless projection function. Depending on the operating system version, it may be called "Wireless Projection" or "Broadcast." This method is based on technology Miracast, which allows the screen image to be transmitted in real time without any compression noticeable to the eye.
To activate the feature, unlock your phone and swipe down to open the control panel. Find the "Wireless Projection" or "Screen Mirroring" icon. If the icon isn't visible, tap the edit button (usually a pencil or three dots) and add the desired widget. Once enabled, the feature will search for available devices within range.
On the TV side Samsung It is also necessary to activate signal reception. On models with the operating system Tizen This often happens automatically, but sometimes you need to manually launch the Screen Casting app or select a signal source. Screen Mirroring in the list of inputs. When the TV appears in the list on your smartphone, simply tap its name to pair it.
☑️ Check before connection
In some cases, the system may ask for permission to connect. A pop-up window with a code or confirmation request will appear on the TV screen. Use the remote control. Samsungto select "Accept" or enter the code if it's displayed on your smartphone. After a successful handshake, the phone's image will be mirrored on the large screen.
Samsung SmartThings app for deep integration
If standard screen projection tools are unstable or you require advanced control functionality, the official app is the best solution. SmartThingsThis ecosystem program from Samsung It allows you to not only stream content but also use your phone as a remote control, transfer files, and even control your smart home. The app is available for download in the store. AppGallery or through Google Play (on older Huawei models).
After installation, launch the application and log in to your account. Samsung AccountClick the "Add Device" button and select the "TV" category. The app will scan the network and find your TV. To confirm the pairing, a code will appear on the TV screen, which you must enter on your smartphone. This ensures a secure connection between the devices.
One of SmartThings' key features is the ability to mirror specific content rather than the entire screen. You can launch a video in your gallery or browser, tap the "Mirror" button (the rectangle icon with waves), and select your TV. This allows you to use your phone for other tasks while the video plays on the TV.
Why is SmartThings better than standard projection?
Standard projection (Miracast) mirrors the entire screen, including notifications and system sounds, and drains battery life. SmartThings allows you to stream only the media file, using the phone's resources for decoding but leaving the TV interface for playback controls, which often results in a smoother picture.
It's important to note that all app features require a stable internet connection, not just a local network, especially during initial setup. Also, make sure mobile device connections are allowed in your TV's privacy settings.
Wi-Fi Direct technology for direct transmission
Protocol Wi-Fi Direct Allows you to create a direct connection between devices without a router. This is ideal if your home network is overloaded or your router doesn't support the required standards. In this mode, the TV Samsung acts as an access point or peering node, receiving the signal directly from Huawei.
To use this method, you need to go to the network settings on your TV and find the item Wi-Fi DirectEnable this feature. The device name and, in some cases, the connection password may appear on the screen. On your smartphone, go to Wi-Fi settings, find the network with your TV's name (often containing [Direct] in the name), and connect to it.
Once the connection is established, you can use compatible apps to transfer files or stream. Gallery Huawei and video players usually support sending content via Wi-Fi Direct. Select a photo or video, tap the Share button or the DLNA/Cast icon, and select the detected device.

Using Wi-Fi Direct is especially useful when you need to quickly share photos with guests or launch a presentation without having to configure complex network settings. Data transfer rates in this mode can reach 250 Mbps, sufficient for Full HD video.
Streaming via built-in browser and DLNA
Another way is to use technology DLNAMost modern televisions Samsung have a built-in media player that supports this standard. On a smartphone Huawei You can use a file manager or gallery to search for rendering devices on the network. This method is advantageous because it doesn't burden the phone's processor with real-time video stream encoding.
First, make sure the "Media" app or a similar app is running on your TV, which scans the network for available content. On your phone, open a video or music file. In the playback menu, find the "Cast" button. If your phone and TV are on the same network, your TV will appear in the list.
The advantage of DLNA is that your phone simply acts as a remote control. You can turn off your smartphone's screen or launch other demanding games, and playback on your TV will continue uninterrupted. This also significantly saves battery life.
⚠️ Important: File formats must be supported by your TV. If the video doesn't play, your TV may not have the required codec (for example, MKV with a specific audio track), and you'll need to convert it or use a third-party player.
In the operating system Android (which Huawei phones run on) DLNA functionality is often built into system components. However, if the standard gallery doesn't recognize your TV, you can install a third-party player, such as VLC for Android or BubbleUPnP, which have more powerful search and decoding tools.
Solution and troubleshooting
Despite the simplicity of the technology, users may encounter connection issues. The most common is that the phone doesn't detect the TV. In this case, first check whether "Guest Network" mode or AP Isolation is enabled on the router. These features prevent devices within the same network from communicating with each other.
Another common issue is audio and video desync or constant buffering. This indicates a weak Wi-Fi signal. Try moving closer to the router or TV. It's also worth closing background apps on your phone that may be consuming bandwidth, such as torrents or cloud syncing.
If nothing helps, reset the network settings on both devices. On the TV, you can do this via Settings → General → Network → Network ResetOn Huawei the path is: Settings → System & updates → Reset → Reset network settingsAfter both devices restart, try pairing again.
In rare cases, the problem may lie with antivirus software or a firewall installed on your router or phone. Temporarily disable the protection to check if it's blocking the local connection. Also, make sure the date and time on both devices are synchronized, as this affects the connection's security certificates.
