Modern multimedia capabilities make it easy to stream content from a mobile device to a big screen, but owners of equipment from different brands often face the nuances of customization. If you have a Samsung smartphone and a Xiaomi TV running Android TV or PatchWall, the process of combining devices may seem unobvious due to the lack of a single ecosystem. However, standard wireless data protocols such as Miracast and DLNA ensure compatibility of most gadgets without the need to buy additional equipment.
The main difficulty is that Samsung uses proprietary Smart View technology, while Xiaomi TVs often focus on standard Google Cast or built-in Mi Remote features. Despite the differences in the software, there are several proven methods to successfully “friend” these devices. In this article, we will detail all the ways of connecting, from simple built-in features to using third-party applications for professional broadcasting.
Before you start setting up, it’s important to understand that connection stability is directly dependent on the quality of your home network: Both devices must be connected to the same 5GHz Wi-Fi network to minimize delays in high-resolution video transmission, and ignoring this requirement can lead to sound and image dissynchronization or permanent connection breaks during viewing.
Device preparation and network verification
The first and most critical step is to set up your network environment correctly. Many users mistakenly believe that it is enough to turn on Wi-Fi on both devices, but the proper operation of the detection protocols (Discovery Protocols) requires compliance with certain conditions. Make sure that your router distributes a network in the 2.4 GHz or 5 GHz band, and both gadgets are in the same network segment.
On Xiaomi TVs with PatchWall shell or pure Android TV, you need to activate the standby mode for external connections. To do this, go to the settings menu, select Settings → Network and Internet and make sure that the connection status is active. Some models require additional activation of the “Wireless Monitor” or “Transaction” function, which is often hidden in the depths of the system menus.
☑️ Checking connection readiness
On a Samsung smartphone, it’s also worth checking your energy saving settings. Aggressive battery optimization algorithms can block the background process of finding devices, making your phone “invisible” to the TV. Go to Settings → Device Maintenance → Battery and make sure that the power saving mode does not limit the operation of network modules.
⚠️ Note: If your router supports the function «AP Isolation, enabling this option will prevent devices on the same network from seeing each other. To connect the phone to the TV, this feature must be disabled in the router settings.
Use the built-in Smart View feature on Samsung
The easiest and most native way to stream an image is to use Smart View technology, which is built into Samsung’s One UI shell.This feature is based on the Miracast standard, which is supported by most modern TVs, including Xiaomi models. To run, lower the notification curtain and find the Smart View icon (sometimes it can be called Translation or Wireless Monitor depending on the Android version).
Once activated, the phone will start scanning available devices in range. Your Xiaomi TV should appear on the list. If the device is found, click on its name. On the TV screen, a request for confirmation of connection may appear, which must be received using the remote control. The connection process can take from 5 to 15 seconds.
It's worth noting that the quality of the image transfer depends on the power of the Wi-Fi module. When using Smart View, the phone creates a direct connection to the TV, which can temporarily reduce the speed of the Internet on the smartphone itself. If you plan to play games or work with text, it's better to turn the phone horizontally and turn off notifications so that they do not overlap the content on the large screen.
If the TV is not automatically located, try to approach the router or TV. Sometimes interference from microwave ovens or neighboring Wi-Fi networks can signal. Also make sure that the Xiaomi TV is open Wireless Monitor app (if it is on the pre-installed list), as some models require manual waiting mode signal.
Broadcasting via Google Home and Chromecast
Because Xiaomi TVs run on Android TV, they have built-in support for Google Cast technology, an alternative and often more stable way to stream content, especially for videos from YouTube, Netflix or other streaming services. To manage this process on the Samsung phone, you will need the Google Home app, which can be downloaded for free from the Google Play Market.
Once you install the app, launch it and log in to your Google account. The program will automatically scan the network and find a connected Xiaomi TV. Select a device from the list. In the control menu that opens, click the Cast my screen button. The system will warn you of possible performance declines and audio notifications - confirm the action.
| Parameter | Smart View (Miracast) | Google Cast (Chromecast) |
|---|---|---|
| Type of connection | Straight (P2P) | Through the router (Cloud/Local) |
| Internet dependency | No requirement (wi-fi module only) | A stable Internet is required |
| Image quality | Depends on the Wi-Fi signal. | High (adaptive) |
| Phone battery consumption | High-pitched | Medium. |
The advantage of the method through Google Home is that the TV itself decodes the video stream if you stream content from supported applications, which reduces the load on the smartphone processor and allows you to use the phone for other tasks without interrupting playback. However, to duplicate the entire screen (screen copy), the phone will still encode the image in real time.
💡
If you are streaming through Google Home, try the Google Home app settings on your phone to enable the “Normal Volume” option or restart the router.
Third-party applications for enhanced capabilities
In situations where standard methods are unstable or require additional features (such as transferring files of a certain format), third-party solutions come to the rescue. One of the most popular and reliable applications is Web Video Caster or Castify, which allows you to stream not only videos from the browser, but also files from the local memory of the phone, bypassing the limitations of embedded players.
To get started, install the selected app on your Samsung phone and, if required, a companion app on your Xiaomi TV (often just find the device online). The interface of such programs is usually intuitive: you select a file or link, and then specify the target device. Third-party compression algorithms often work more efficiently than system ones, reducing latency (lag) when displaying an image.
You should pay special attention to the settings of the codecs. If the video is not played or comes with jerks, go to the settings of the translation application and try to change the coding format from the H.265 on H.264. Xiaomi TV budget segment may not cope with decoding heavy 4K-Real-time files, so reducing bitrate can solve the problem.
⚠️ Warning: Free versions of third-party apps often contain ads that can overlay the image on the TV. It is recommended to use paid versions or versions of "Pro" for comfortable viewing without interruptions.
Wired connection via USB-C to HDMI
If wireless connectivity is not possible due to poor signal or maximum image quality is required without compression, you can use a cable connection. For this you will need a USB-C to HDMI adapter. It is important to check whether your Samsung phone model supports video transmission via a charging port. The flagship Galaxy S and Note series usually support MHL or Alt Mode technology, while budget models (Galaxy A series) may not have this feature.
Connect the adapter to the smartphone, and then connect it HDMI-switch the signal source on the TV to the appropriate port HDMI 1 HDMI 2.The image must appear automatically. Unlike wireless methods, there is almost no latency, making this method ideal for games or presentations.
Why is the cable not working on some Samsungs?
When using the cable, the phone can quickly discharge, as there is an active power consumption. It is recommended to use an adapter with an additional charging port to simultaneously broadcast the image and replenish the battery of the device.
Troubleshooting and troubleshooting
Even if you follow all the instructions, there can be technical failures. If a Samsung phone can't see a Xiaomi TV, try restarting both devices. This trivial action often clears the cache of network services and resets error detection protocols. Also make sure that both devices have LAN permissions enabled.
Image quality issues (artifacts, green screen) are often solved by changing the resolution. In Smart View settings or in the developer settings, you can force the resolution of 1280×720 instead of 1920×1080 or 4K. This will reduce the load on the communication channel and stabilize the flow.
💡
Rebooting the router solves 80% of device detection problems on the local network, as it updates the ARP table and resets the dangling DHCP-leases.
If audio is not available, check the audio output settings in the app itself, which is broadcasting. Sometimes the sound continues to go through the speaker of the phone while the video is displayed on TV. In this case, in the quick settings menu of Samsung, you need to select the output device (media output) and specify the TV.
