Android ecosystem owners often face the need to showcase media content on a big screen, especially when a smartphone is Samsung branded and a TV is made by Xiaomi. Despite the differences in software shells, modern technology makes it easy to organize wireless communication between devices, eliminating the need to copy files to a flash drive or use complex cable adapters.
There are several proven methods to accomplish this task: the choice of the specific method depends on the version of the operating system, the model of the TV, and the availability of an active Internet connection. In this article, we will discuss each option in detail, including the built-in features of Mi TV and third-party applications for Galaxy.
Wireless broadcasting through built-in functionality
The easiest and fastest way is to use the built-in Mi Cast or Wireless Projection feature. In Samsung smartphones, this technology is called Smart View. Both devices must be connected to the same Wi-Fi network. If the router is broadcasting at 5 GHz, the data transmission stability will be significantly higher, which will eliminate delays when viewing the gallery.
To get started, lower the notification curtain on your phone and find the Smart View icon. Once activated, the system will start searching for available displays. To properly work the Miracast protocol, both devices must be in the same router subnet, even if you are using a guest Wi-Fi network. Select your Xiaomi TV from the list. On the TV screen, a request for confirmation of the connection may appear, which must be received by the remote control.
Once successfully paired, the smartphone screen will be displayed on the TV, so you can browse through the gallery, and the image will be broadcast in real time. The quality of the picture depends on the Wi-Fi module power and the distance to the router. If the signal is weak, artifacts or desynchronization are possible.
⚠️ Note: When using Screen Mirroring, the smartphone battery drains much faster, and it is recommended to keep the device charged or connect it to a power source during long presentations.
In some cases, the system may suggest that you choose to operate in a mode called “screen Translation” or “Photo Translation”; the second option is more energy efficient, since it does not require constant transmission of the video stream of the interface, but only sends static images as you switch.
Using Google Chromecast technology
Xiaomi TVs are powered by Android TV, which means Chromecast technology is built-in, allowing content to be streamed directly from apps without fully mirroring the screen, a method that often provides better image quality, as the TV downloads the media file from the link itself, and the phone acts only as a remote control.
To implement this method, make sure that the phone has Google Home installed. It will automatically detect your Xiaomi TV. Click on the device icon in the app and select Translate Screen or open the Google Photo Gallery, select a snapshot and click on the broadcast icon. This method is especially convenient if the standard Smart View is unstable.
The advantage of this method is that it supports codecs. The TV can decode formats that the phone doesn't support, or vice versa. In addition, you can control playback, and you can use the phone for other tasks without interrupting the slides on the big screen.
💡
If the TV is not visible in the Google Home app, check if the Guest Mode or New Device feature is enabled in the Chromecast settings on the TV itself.
Importantly, when you stream through Chromecast, your phone and TV use an Internet channel to transmit data, and if you have a tariffed traffic, it can lead to unexpected costs, although when you connect to your home Wi-Fi, this is not relevant. Connectivity stability is critical here: when Internet speed drops, the broadcast can be interrupted.
Applications for DLNA and Local Area Network
If the wireless mirror is latent, DLNA is a great solution, allowing you to transfer media files over the local network without compression and loss of quality. To do this, you need to install a media player app on your Xiaomi TV, such as Video & TV Cast or use the built-in Media Player. Samsung phone will also need an application that supports DLNA, such as BubbleUPnP or LocalCast.
The principle is simple: you pick a file in an app on your phone, and you point to your TV as the playback device, and it's transmitted directly over the Wi-Fi network, and it's ideal for viewing high-resolution 4K photos, because it doesn't put the strain on the smartphone processor that mirrors the screen.
List of popular applications for the organization DLNA-server:
- 📱 BubbleUPnP – a powerful combine for Android with support for cloud storage.
- 📺 Xiaomi Mi Remote – the official application that sometimes allows you to manage media files.
- 🖼️ LocalCast – a simple and understandable solution for fast transfer of photos and videos.
- 📂 ES Conductor – has a built-in function DLNA, If you already have this file manager installed.
⚠️ Note: When using third-party file managers on Android TV (for example, ES Conductor on TV) make sure you give the necessary permissions to access the device's memory. Without this, the TV will not be able to "see" the transmitted files.
DLNA requires both devices to be on the same network. Unlike Miracast, there's no video stream on the screen, so the phone's battery is more economical. However, the phone's interface on the TV won't show up -- you'll only see selected photos or videos.
Preparation of devices for connection
Before you start setting up, you need to make sure that both devices are ready to go, and often connection problems arise from trivial network settings or outdated software, and it will take a couple of minutes to check these parameters, but save time to fix errors in the future.
☑️ Checklist of preparations
First, check the operating system version. On Samsung, go to Settings → About Phone → Software Information. On Xiaomi TV, the path usually looks like: Settings → TV → System Information. If updates are available, they’re better installed, as security patches and new Wi-Fi drivers often improve connection stability.
Sometimes network equipment gets clogged and stops correctly distributing data packets between devices on the local network. Simply turning off the router's power for 10-15 seconds often solves the problem when the TV stops seeing the phone.
The table below will help to compare the main characteristics of the connection methods:
| Parameter | Miracast (Smart View) | Chromecast | DLNA |
|---|---|---|---|
| Image quality | Depends on the Wi-Fi signal. | High (adaptive) | Maximum (no compression) |
| Phone battery consumption | High-pitched | Medium. | Low. |
| The Necessity of the Internet | No requirement (wi-fi only) | Preferably. | Not required |
| Management convenience | A full mirror. | Control panel | Choice of files |
If you plan to use your TV as a digital photo frame often, you should consider DLNA, which provides the best color reproduction and detail, as it does not use video stream compression, which is characteristic of wireless mirroring.
Solving Connection Problems
Despite the standardization of technology, users often face situations where a Samsung phone “does not see” a Xiaomi TV, which can be caused by router firewall settings that isolate devices from each other (AP Isolation), in which case devices see the router, but cannot communicate with each other.
Try to manually prescribe. DNS-Addresses in the Wi-Fi settings on the TV. Use public DNS, For example, from Google (8.8.8.8) or Cloudflare (1.1.1.1), it can improve communication with device discovery servers, and Wi-Fi frequency switching can also help: If the router is dual-band, connect both gadgets to the 2.4 GHz network, as it has a longer range and better breaks through walls, although less speed.
