Integrating Xiaomi smartphones into the smart home ecosystem, where Samsung TVs are often the centerpiece, opens up access to enhanced media functionality. Owners of devices based on the MIUI shell or the new HyperOS can not only display images on the big screen, but also use the phone as a universal remote control, especially for Samsung Smart TV models that support various wireless protocols such as Miracast and AirPlay 2.
Synchronizing devices from different brands can seem complicated due to software differences, but modern standards make it much easier. You don't need to be an expert in networking to establish a stable connection between a gadget and a TV. You just need to follow step-by-step instructions that take into account the specifics of the Android operating system and the Tizen OS platform from Samsung.
In this guide, we will take a look at all the available connectivity methods, from standard system functions to the use of specialized applications. You will learn how to avoid delays when broadcasting video, how to configure voice control and what nuances exist when using wired adapters. The key to wireless connection is to find both devices on the same Wi-Fi network at a frequency of 5 GHz for maximum data transfer speed.
Use of the Translation function in MIUI and HyperOS
The fastest way to display a picture from a Xiaomi smartphone on a Samsung TV is by using a built-in system function. In the MIUI shell, it is called Translation, and in newer versions of HyperOS it can be called Screen Translation or Cast. This technology is based on the Miracast protocol, which is supported by most modern Smart TVs, including the QLED and Neo QLED series models.
To get started, make sure your TV is on and connected to the same Wi-Fi network as your phone. Some Samsung models require you to manually allow external devices to connect through the settings menu if automatic detection fails. Open the control center on your smartphone by swiping down from the top right corner, and find the Translation icon. The system will begin searching for available displays within the network radius.
Once you find your TV on the list, click on the name of the TV, and you may see a connection confirmation request on the TV screen that you need to receive with the remote control, and from that point on, the image from your mobile device will be duplicated on a large screen in real time, which is ideal for viewing a photo gallery or showing presentations.
- 📱 Make sure your TV has Screen Mirroring enabled in the signal source menu.
- 📶 To reduce delays, use a Wi-Fi router with support for Wi-Fi 5 (802.11ac) higher.
- 🔄 If the connection breaks, try restarting the Wi-Fi module on both devices.
⚠️ Note: When using the screen broadcast function, the smartphone can get significantly warmer and the battery will be consumed faster than usual.
Connecting through Samsung SmartThings app
The official Samsung SmartThings app is a powerful tool for managing the Korean brand’s ecosystem and works great with Xiaomi smartphones. To work properly, you need to download the app from the Google Play store and register a Samsung account if you don’t already have one. This software allows you not only to stream content, but also to manage your TV settings, switch channels and launch apps directly from your smartphone screen.
The setup process starts with launching an app and adding a new device. SmartThings automatically scans the network and prompts you to add the TV you find. Once paired, you will access a virtual remote that completely replaces the physical controller. This is especially convenient when the physical remote is lost or its buttons are out of order.
Smart View, which is an in-app feature that allows you to stream videos, music and photos from your phone's gallery. Unlike the system stream, it often offers finer customization of image quality and soundtracks, and it supports the creation of automation scenarios, such as turning on the TV when you come home.
☑️ Check before connecting SmartThings
It’s worth noting that some control features, such as typing text from a phone’s keyboard, may require a stable internet connection, not just a local area network.If the app doesn’t see the TV, check the firewall settings on the router, which can block ports needed for the DLNA protocol to work.
Broadcasting via Google Home and Chromecast
Many modern Samsung TVs have built-in support for Google Chromecast technology, making them fully compatible with Xiaomi smartphones without installing additional software. To use this method, the phone must have the Google Home app, which is the control center of the smart home from Google, which is considered one of the most stable for streaming videos from applications.
Open the Google Home app and find your TV in the device list. Click on the device icon, then select the "Cast my screen" button. The image from your phone will instantly appear on your TV, a feature of which is optimizing video streaming, which often gives a better picture than the native MIUI function.
It is important to distinguish between broadcasting a browser tab or a specific video from an application (for example, YouTube or Netflix) and full mirroring of the screen. In the first case, the phone acts only as a remote control, and the video is downloaded by the TV directly from the Internet, which saves battery.
| Comparison parameter | Miracast (Translation) | Chromecast Built-in | SmartThings |
|---|---|---|---|
| Delay (Latency) | Medium (notable in games) | Low (for video) | Low. |
| Battery consumption | High-pitched | Low (remote mode) | Medium. |
| Image quality | Depends on the Wi-Fi signal. | Stable HD/4K | High. |
| TV administration | No. | Limited. | Complete. |

Using Xiaomi Smartphone as a Remote (Mi Remote)
Xiaomi smartphones have the unique advantage of having an integrated infrared port (IR Blaster) located on the upper end of the case, which allows the phone to be used as a universal control panel for any household appliances, including Samsung TVs, even without an Internet connection. The Mi Remote app is already pre-installed on most of the brand’s devices.
To set up, open the app and click "Add remote." Select the TV category and search for the Samsung brand in the list. Follow the instructions on the screen: the phone will send test signals, and you need to confirm their performance with the "Yes" or "No" buttons. After successful testing of all the functions, the remote will be saved.
The infrared method has its limitations: it requires a line of sight between the phone and the receiver of the signal on the TV, unlike Wi-Fi methods. However, this makes it indispensable in situations where the router is unavailable or the network is overloaded. You can control the volume, channel switching and signal source (HDMI, TV, AV) with the accuracy of the original remote.
- 🔴 The infrared port works on the principle of direct radiation, so point the upper end of the phone towards the TV.
- 📺 The application supports the creation of multiple profiles of remotes for different rooms or devices.
- ⚙️ Some Smart Functions TV (For example, text input) via the IR port is not available, only basic control.
⚠️ Note: If your Xiaomi does not have an IR port (usually budget models or tablets), the Mi Remote function through infrared radiation will not work.
Wired connection via USB-C to HDMI adapter
For users who require maximum image quality without compression and delays, or for those who do not have access to Wi-Fi, there is a wired way to connect. Xiaomi mid-range and flagship smartphones often support video output via a USB Type-C port using the MHL or DisplayPort Alt Mode standard. You will need a special adapter (hub) with HDMI output.
Connect the adapter to your smartphone, then connect it with an HDMI cable to the corresponding port on your Samsung TV. Switch the TV signal source to the desired connector (for example, HDMI 1). Unlike wireless methods, here the picture is transmitted in the original resolution supported by the phone screen, up to 4K at 60 Hz, if the smartphone model allows it.
Not all Xiaomi models support video output via USB-C. Budget devices can only transfer data and charge. To check support, you can consult the CPU specification (usually you need a level at least lower than the Snapdragon 800 series or similar MediaTek with video support) or simply try to connect an adapter. When successfully connected, the phone will automatically go into screen expansion or mirroring mode.
💡
When using a wired connection via USB-C Hub with a power port, be sure to connect the charger to the hub.This will prevent the smartphone from quickly discharging while watching high-resolution movies.
Solving and optimizing the connection
Even with the right setup, users can face problems: audio and video desynchronization, low resolution or periodic connection breaks. Often the reason lies in MIUI power saving settings, which aggressively close the background processes, you need to add the apps you use (SmartThings, Google Home, YouTube) to the exception list and allow autorun.
Another common problem is using 2.4GHz Wi-Fi, which is heavily congested in apartment buildings. Switching your router and devices to 5GHz dramatically improves the stability of video streaming. Make sure your router distributes both networks and your smartphone is connected to the faster one.
If a Samsung TV can't see a Xiaomi phone, try resetting the network settings on both devices. Sometimes it helps to disable the Private Network feature in your Android Wi-Fi settings, as it hides the device from other gadgets on the network. Also check if the antivirus or firewall on the phone blocks local connections.
💡
The stability of the wireless connection depends on the quality of the router and the absence of physical barriers. 4K-broadcasting HDMI It is the only guaranteed uninterrupted solution.
