Modern multimedia systems allow you to turn any TV into a smart entertainment center, and Xiaomi Mi Box S is one of the leaders in this segment. Often users wonder how to quickly display an image from a smartphone to the big screen to watch a movie, presentation or photos. The process of synchronizing devices has become much easier thanks to the introduction of modern wireless protocols and integration with the Android ecosystem.
To get started, you need to make sure that both your Android smartphone and the console are on the same local Wi-Fi network, a fundamental requirement for most broadcasting methods, as the signal is transmitted through the router, and if you ignore this, finding available devices can take a long time or not work at all.
There are several proven ways to connect, each with its own features: you can use built-in operating system features, specialized applications from Google or third-party streaming programs, the choice of the specific method depends on the version of the OS on your phone and personal preferences in content management.
Preparation of equipment and network
Before you start setting up, make sure that the Xiaomi Mi Box S is connected to the TV via the phone. HDMI-The system must be loaded to the main screen, and the top right corner should show the status of the Internet connection, and the stability of the connection is critical for transmitting high-resolution video stream without delays and artifacts.
Check the software version on the console, as old firmware may not work properly with new data protocols. Go to Settings → TV → System Update and make sure you have the current version installed. Often, it is the system update that solves problems with the visibility of the device on the network.
⚠️ Warning: Make sure your router does not activate customer isolation feature (AP Isolation, which prevents devices on the same network from sharing data with each other.
You should also pay attention to the frequency of the Wi-Fi signal. To transmit heavy 4K content, you prefer to use the 5 GHz bandwidth, which provides higher bandwidth. If your router is dual-band, connect both the phone and the console to this network for maximum performance.
💡
Use the Ethernet cable via USB-adapter for Mi Box S, if the wireless connection is unstable, this will provide the maximum data transfer speed.
Broadcasting through the built-in Chromecast feature
The easiest and most common way to connect your phone to a console is to use Chromecast built-in technology, which is built directly into the Android TV operating system on which the Mi Box S is based, and does not require additional software to be installed.
To get started, open an app on your smartphone that you want to show content from, such as YouTube or Netflix. Find the broadcast icon (a rectangle with waves in the corner) and click on it. In the list that appears, select your Xiaomi Mi Box S.
If you want to stream the entire screen of your smartphone, not just the video from the app, use the system function “Translation”. On many Xiaomi devices and other Android smartphones, this item is in the notification curtain. Once activated, the system will automatically find available devices on the network.
It's important to note that picture quality can depend on the power of the phone's processor and the speed of Wi-Fi. When broadcasting the whole screen, the delay can be anywhere from 1 to 3 seconds, which is normal for this technology.
☑️ Pre-broadcast checks
Use of the Google Home app
If the smartphone’s built-in features don’t work properly or the device isn’t automatically located, the official Google Home app comes to the rescue.This is a universal remote control for the entire smart home ecosystem that also does a great job of duplicating the screen on Android TV.
Download and install the Google Home app from the Play Market store on your phone. Once you log in to a Google account that matches what you're using on the console (or just on the same network), the program will automatically detect the Xiaomi Mi Box S.
In the app interface, find your console card and click on the "Cast my screen" button. The system will request permission to record and broadcast the contents of your display - confirm the action. From now on, everything that happens on the phone screen will be displayed on the TV.
| Parameter | Chromecast in the app | Google Home (screen) | Third-party annexes |
|---|---|---|---|
| Delay. | Minimum | Medium (1-3 sec) | Depends on the software. |
| Quality. | Up to 4K HDR | Up to 1080p/4K | Varying. |
| Battery consumption | Low. | High-pitched | Medium. |
| Sound. | It's on TV. | It's on TV. | Often requires adjustments |
Google Home is especially useful when you want to show a photo gallery or navigation interface, but it is worth remembering that in this mode the phone does not go to sleep, and the energy consumption increases significantly.
Connection via Miracast Protocol
For users whose smartphones do not have Google services or prefer open standards, Miracast protocol is relevant. On Xiaomi consoles, this technology is often implemented through the built-in “Transaction” application (Cast) or requires the installation of additional software from the app store.
Unlike the Chromecast, Miracast creates a direct Wi-Fi connection between your phone and the console (Wi-Fi Direct) bypassing the router. This can be useful if your home network is overloaded or limited. Find the Wireless Display or similar item on the Mi Box S app menu.
On your phone, activate the Wireless Monitor or Wireless Display Connection function in your connection settings. Your phone will start searching for available devices. Once the Xiaomi Mi Box appears, select it to pair.
What if Miracast doesn’t work?
The advantage of this method is independence from the Internet channel, but the stability of the connection depends entirely on the quality of the Wi-Fi modules in the phone and console.
Third-party streaming apps
When standard methods fail, third-party solutions come to the rescue. The Google Play store on Xiaomi Mi Box S offers a variety of live streaming apps, such as AirScreen, LocalCast or Web Video Caster. These programs often support a wider range of codecs and formats.
AirScreen, for example, lets you connect not only Android devices, but also iPhones (via AirPlay) and Windows laptops. Once installed on the console, launch the app and follow the instructions on the screen, and it will create a virtual receiver that will be visible to other devices.
To transfer files from your phone, you can use DLNA-enabled file managers, such as X-plore or the built-in Explorer with DLNA function. In this case, you select a file on your phone and send it to a renderer (set-top box) that will play the media.
⚠️ Note: When using free versions of third-party apps, advertising may be displayed on the TV screen. For complete comfort, consider buying a premium version.
This approach is especially useful for playing video files stored in the phone’s memory that are not supported by standard players or have specific subtitles.
💡
Third-party applications are the best solution for cross-platform work (iOS + Android) and playback of local files of complex formats.
Addressing problems and delays
Users may face various difficulties in setting up, such as desynchronizing audio and video or missing images altogether, most often due to software versions or temporary network services failure.
If the image twitches or is low resolution, try to lower the broadcast quality in the source app settings, rebooting the router and both devices can also help, and sometimes cleaning the cache of the Google Play Services app on the phone helps.
If the phone doesn't see the console, check the firewall settings on the router. Make sure the ports for multicast traffic are open. IP-Address for the console to avoid addressing conflicts.
Keep in mind that live streaming is a huge strain on the processor and battery of your smartphone, and it is recommended to keep your phone connected to a charger or power bank during long browsing sessions.
