Today’s users often face the need to bring multimedia content from a mobile device to the big screen. The owner of a Samsung smartphone and a Xiaomi TV (or Redmi, Poco) has an excellent opportunity to create a single ecosystem for watching movies and games. Android ecosystems allow you to do this in several ways, each of which has its own characteristics depending on the version of the MIUI or HyperOS firmware.
The main challenge in pairing is to ensure a stable data channel, whether it's a wireless Wi-Fi network or a direct connection. It's important to understand that transmission protocols can vary from standard screen mirroring to streaming media files through a streaming channel. DLNA. In this article, we will discuss all the current methods that will help you synchronize devices without using third-party devices. HDMI-cable.
Before you start setting up, you need to make sure that both gadgets work correctly.The software needs to be updated to the latest available version, as older builds may contain errors in wireless modules. Let's look at the step-by-step algorithm of actions for different use cases.
Preparation of equipment and network
The foundation of a successful connection is the right setup of the local network. Both devices must be in the same information space, that is, be connected to the same Wi-Fi hotspot. If your router supports dual-band mode, make sure that both the phone and the TV use the same frequency, preferably 5 GHz, to minimize latency.
Xiaomi TVs need to activate external connection mode, usually with a separate app or feature on the menu, the name of which may vary depending on the regional version of the firmware, often called Wireless Monitor, Miracast or Broadcast.
⚠️ Note: If your router has Client Isolation, the devices won’t see each other. Make sure that this option is disabled in the router settings, otherwise the local network will block the exchange of data between gadgets.
On the Samsung smartphone side, it’s also worth checking the power saving settings. Aggressive battery-saving algorithms can force the background processes needed to maintain a stable video stream.
☑️ Checking before connection
Use of the built-in Smart View function
The easiest and most native way for Samsung appliance owners is to use Smart View technology, which is built into the One UI shell and does not require additional apps from the Google Play store. It is based on the Miracast standard, which is supported by most modern Xiaomi TVs.
To start the function, you need to unlock the smartphone screen and swipe from top to bottom to open the Quick Settings Bar. You need to find the Smart View button among the icons. If it is not on the first page, flip the list to the right or click on three dots to edit the menu. Once activated, the system will start searching for available devices within the network range.
When the name of your Xiaomi TV appears on your phone screen, click on it. The TV screen may have a request for connection permission, which must be confirmed by the remote, from now on, the image from the mobile device will be broadcast to the large screen in real time.
- 📱 High compatibility with the One shell UI Samsung.
- 📺 Support for permission before 4K Provided with a powerful Wi-Fi signal.
- 🎮 The ability to use the phone as a game controller in some applications.
It's worth noting that when you use Smart View, you get a lot more battery consumption, because you're always running the Wi-Fi module in high load mode and the processor encoding the video stream, and if you're planning a long browsing session, you'd better connect your smartphone to the charger.
💡
To reduce latency (input lag) during games, close all background applications on the phone, except for the broadcast content, this will free up RAM and CPU time.
Broadcasting via Google Home and Chromecast
Xiaomi TVs are powered by Android TV, which means built-in support for Google Cast technology, which allows you to stream content not by fully mirroring the screen, but by sending a link to the media file directly to the TV, which reduces the load on the smartphone and provides a more stable picture.
To implement this method, you need to install the Google Home app on your Samsung phone if it is not already integrated into the system. After launching the app and logging into your Google account, click on your TV icon in the list of devices. From the menu that opens, select the option to Translate screen.
The advantage of this method is that you can use the phone for other tasks while the video is played on TV. However, not all applications support direct content submission, and in such cases you have to use the full-screen mirroring mode, as we described in the previous section.
| Parameter | Smart View (Miracast) | Google Cast |
|---|---|---|
| Type of transmission | Screen mirroring | Streaming link |
| Dependence on the phone | High (screen should be on) | Low (you can fold the application) |
| Image quality | Depends on the Wi-Fi signal. | Maximum (up to 4K HDR) |
| Battery consumption | High-pitched | Medium. |
If the Internet channel is narrow, buffering and lowering image quality are possible before the cache loading is completed.
Remote management applications
If your goal is not so much to stream video as to control a TV from your phone, it’s worth considering specialized apps. The official Google TV app (formerly Google Home) lets you use your smartphone as a full-fledged remote control with a keyboard for typing.
There are also third-party solutions, such as Mi Remote (if the phone model supports infrared port, which is rare for Samsung’s flagships of recent years) or universal remotes like the Peel Smart Remote. However, Wi-Fi is best suited to applications developed specifically for the Android TV ecosystem.
One of the most popular solutions is the Android application. TV Google's Remote Control, which allows you not only to switch channels and adjust volume, but also to type text from your phone's keyboard, which is much more convenient than using the on-screen remote on your TV. PIN-code that will appear on the TV screen.
⚠️ Note: When using third-party remote applications, make sure they have the necessary permissions on the Android system. Lack of permissions to access the LAN will lead to a connection error.
Some users prefer to use file transfer applications that also have a media player management feature, such as Send Files to TV, which allows not only to flip a video file, but also to play it on a large screen using the phone as a controller.
The Secret Debugging Function
Connection problems and their solution
Despite standardizing protocols, users may experience situations where a Samsung phone doesn’t see a Xiaomi TV or the connection is constantly interrupted, most often due to router security settings or conflict. IP-address.
The first thing you need to do is reboot both devices, which is a trivial but effective step that allows you to reset the cache of network services and reconfirm DHCP-lease. If that doesn't work, try manually prescribing static ones. IP-addresses for both devices in the router settings, linking them to MAC-address.
Another common reason is to use a guest Wi-Fi network. Many routers by default isolate guests from the main network where the TV may be located. Make sure both devices are connected to the main SSID, not the guest one.
- 🔄 Check if the “plane” mode or Wi-Fi energy saving is enabled.
- 🔒 Make sure that the router does not include filtering by MAC-address.
- 📶 Try switching to 2.4 GHz if 5 GHz is unstable over a long distance.
In rare cases, the problem may be due to antivirus software installed on your smartphone or as part of your TV firmware. Try temporarily turning off the firewall or network screen for diagnosis.
💡
90% of connection problems are solved by restarting the router or switching devices to a single Wi-Fi network (same SSID and frequency).
Alternative wired methods
If the wireless connection doesn’t provide the desired quality or causes delays, you can always resort to a proven wired method. To connect a Samsung phone to a Xiaomi TV through a cable, you will need a USB-C to HDMI adapter.
It’s important to consider that not all Samsung smartphones support USB-C image output. The flagship Galaxy S and Note series usually feature a USB 3.1 port or higher with DisplayPort Alt Mode technology. Budget Galaxy A series models may not have this capability, limited to just charging and data transfer.
There is virtually no delay in signal when using the cable, making it ideal for gaming, and the phone will charge during use if the adapter has an additional power port, which solves the problem of fast battery discharge when broadcasting.
To connect, simply insert the adapter into the phone connector, connect HDMI-cable to the adapter and TV, and then switch the signal source to the TV to the appropriate port (HDMI 1, HDMI 2 etc. The image must appear automatically.
