Technology has turned your smartphone into a powerful remote control and multimedia center for your TV. Xiaomi device owners often wonder how to stream content to Samsung’s big screen efficiently without using extra wires. The answer lies in the capabilities of a wireless Wi-Fi network that provides stable data transfer at high speeds, eliminating the need to buy additional HDMI cables or adapters.
The process of synchronizing gadgets from different brands can seem complicated only at first glance. In fact, the Android and Smart TV ecosystems from Samsung share many common communication protocols, such as Miracast and DLNA. These standards are built into the operating shell of MIUI or HyperOS, making the procedure accessible even to inexperienced users. The main thing is to properly configure both devices and make sure that they are on the same local network.
In this article, we will take a look at all the connections available, from built-in system functions to third-party applications, how to stream high-resolution video, photos and even the desktop of a smartphone, and how to quickly fix them so that your leisure time is not overshadowed by technical failures.
Device preparation and Wi-Fi network verification
The first and most critical step is to ensure the right network infrastructure: Both Xiaomi smartphone and Samsung TV devices must be connected to the same Wi-Fi hotspot. If you have a dual-band router at home, make sure both devices operate on the same frequency, preferably 2.4GHz or 5GHz, although modern routers often combine them into the same network with the same name.
Check signal stability. A weak reception level on one of the devices can lead to permanent connection breaks or low bitrates when streaming. Approach the phone closer to the router if the signal is uncertain, and make sure that the TV also receives a sufficient signal level, especially if it is located far from the access point.
⚠️ Note: Guest Network often blocks the ability to detect devices from each other. To successfully connect, make sure both devices are on the main home network where interaction between LAN clients is allowed (LAN).
It’s also worth updating the software on both devices. On a Samsung TV, this is done via the Support → Software Update menu, and on a Xiaomi smartphone via Settings → About Phone → MIUI version. Outdated wireless module drivers may not work properly with new security protocols.
☑️ Checking before connection
Broadcasting the screen through the built-in “Translation” function
The fastest way to display a picture from a Xiaomi smartphone to a Samsung screen is to use the native feature of the system. In the shell of MIUI and the new HyperOS, this option is called Translation or Cast. It is based on the Miracast protocol, which allows you to stream video streaming in real time without the delays that are characteristic of some streaming services.
To activate the function, drop the swipe notification curtain from top to bottom. Find an icon called Translation (sometimes hidden in the optional menu that you need to swipe to left). If you don't find the shortcut, go to Settings → Connection and Sharing → Broadcast. Here you need to activate the switch and wait for the smartphone to scan the available devices.
Your Samsung TV should appear on the list of detected devices. The name usually matches the TV model or the name you give in the Smart Hub settings. Click on it and the TV screen will see a connection request. Use the Samsung remote to select "Allow" or "Accept."
Once paired successfully, the image from the phone is fully copied to the big screen, which means that all notifications, incoming calls and messages will be visible to everyone in the room, so it is recommended to turn on Do Not Disturb mode before watching movies.
💡
If the TV isn’t on the list, try rebooting the Wi-Fi module on your phone: turn it off and turn it on in the notification curtain. Also make sure the TV is running the Screen Translation app or similar service in the Smart Hub menu.
Use of Samsung Smart View App
Although Samsung has officially stopped supporting a separate Smart View app for Android, its functionality has been integrated into the system and is now available through standard means. However, alternative methods or built-in DLNA can be used for more advanced media library management. Xiaomi owners often find it more convenient to use third-party solutions if the standard broadcast is running a non-stable.
One of the most reliable ways is to use the DLNA protocol through file managers or media libraries. The video player or the Gallery app built into Xiaomi can find playback devices. Open the video or photo, click on the transfer icon (usually looks like a wave rectangle or the DLNA logo), and select your Samsung TV.
The good thing about this is that the phone is just a remote control, and the video is transmitted directly from the server or from the phone's memory to the decoder of the TV, which reduces the load on the smartphone's processor and saves battery life, and the picture is often better, because the TV itself processes the video stream.
| Connection method | Type of transmission | Image quality | Impact on the battery |
|---|---|---|---|
| Broadcast (Miracast) | Screen mirroring | Depends on the Wi-Fi signal. | High (screen active) |
| DLNA/push code | Streaming video | Original (without compression) | Low (screen can be extinguished) |
| Applications (YouTube/Netflix) | Cast through server | Maximum (4K HDR) | Minimum |
| USB-C cable to HDMI | Direct connection | No loss. | Charging the phone |
Importantly, when using DLNA, some subtitling formats may not be supported by the TV, so it’s better to use built-in full-screen broadcasting tools that display the picture “as is”.
Broadcasting through YouTube and Netflix apps
The most popular use case is watching videos from online services. YouTube and Netflix apps on Xiaomi smartphones have a built-in casting feature that runs through its own protocol, independent of system mirroring, which ensures the best picture quality and no management delays.
To start playing, open the app on your phone and make sure that the YouTube or Netflix app is running on a Samsung TV (usually already installed in the Smart Hub). In the app on your smartphone, click on the broadcast icon (rectangle with waves in the corner).
The advantage of this method is that the phone doesn't stream a video stream, it just sends a command to the TV: "Put the video on a link like this," so you can easily switch to other apps, respond to messages, or even turn off the phone screen, and playback on the TV will not stop.
⚠️ Note: To work the caste function in apps, Google or Netflix accounts on your phone and TV must be logged in under the same profile, or devices must be on the same subnet. Some Enterprise Wi-Fi Networks Block Ports Required to Detect Chromecast Built-in Devices.
If the broadcast icon doesn't appear, check the app's permissions. In Xiaomi's settings, go to Apps → All Apps → YouTube → App rights and make sure that access to the LAN is allowed. Without that permission, the phone simply won't see the TV on the LAN.
Solving Connection and Buffering Problems
Even when set up correctly, there can be technical difficulties: Often users are faced with a situation where the phone sees the TV, but the connection is reset after a few seconds, and this can be due to MIUI energy saving settings that aggressively kill background processes, including the wireless transmission module.
To fix this, look for Security or Battery mode in your settings, find the application you're streaming through (like Translation or Video) and set the energy saving mode to No Limits. It's also useful to lock the application into memory so that the system doesn't unload it.
Another common problem is desynchronization of audio and video, which often happens when Wi-Fi is overloaded. If you have a 5GHz router, be sure to switch both devices to this frequency, which provides the higher bandwidth required to transmit high-resolution video stream without buffering.
In some cases, network resets can help. On a Samsung TV, you can do this through Settings → General → Network → Network Reset. On a Xiaomi phone, you can simply “Forget Network” in your Wi-Fi settings and reconnect by entering a password.
What if the sound is coming and there is no picture?
Alternative methods and third-party applications
If standard methods don’t work or the functionality isn’t enough, Google Play offers a variety of third-party solutions, and apps like Web Video Caster or Cast to TV allow you to stream content from browsers or file managers that don’t have built-in DLNA or Chromecast support.
These apps often have their own codecs and are better at handling heavy video formats that a native TV player may not recognize: They install a small server application on the TV (via the Samsung app store) that takes stream from the phone and decodes it.
For advanced users who want to maximize performance, there is a possibility of cable connection. Although the request was for Wi-Fi, it is worth mentioning that the USB-C to HDMI adapter (for models with video output support) gives a completely stable picture without compression and delay, turning the phone into a full-fledged media console.
⚠️ Warning: When using third-party free broadcast apps, be prepared for ads that may pop up at critical times, and some may be transmitting your usage data through their servers. Always check the permissions the app requests when installing.
The choice of method depends on your specific tasks. For a quick demonstration of photos, an integrated gallery will suit, for watching online movies - the YouTube app, and for games without lags, a direct mirror display of the screen or a cable connection is best.
💡
Connection stability is directly dependent on router quality and lack of interference in the air. If you plan to broadcast content in 4K often, consider buying a modern Wi-Fi 6 router.
