Modern multimedia systems make it easy to link smartphones to large screens to view content, but sometimes there is a need to break this connection. Users often face situations where the phone continues to automatically connect to a Xiaomi or Mi TV, even when this is not urgently necessary.
Incorrect connection often leads to the fact that notifications from a mobile device begin to duplicate on the TV screen, interrupting the viewing of movies. In addition, the constant search for a device for broadcasting can significantly reduce the battery of a smartphone and create an extra load on the wireless module of the router. In this article, we will discuss in detail all ways of forced and planned disconnection between gadgets.
You will learn how to manage active sessions through the settings menu, how to prevent automatic connection and what to do if standard methods do not work. We will examine the features of the Miracast and DLNA protocols, and also touch on the nuances of working in the Android TV ecosystem.
Analysis of the current type of connection
Before you start taking action to break the connection, you need to determine exactly how your smartphone is connected to the TV. In the ecosystem Xiaomi and Mi use several different technologies of data transmission, and the method of disconnection will depend on the chosen protocol, most often it is wireless mirroring of the screen or transfer multimedia content.
The most common option is Wi-Fi Direct or the built-in Cast, in which the TV acts as a receiver, either by making a direct connection to the smartphone without the router, or by using a shared local area network, and if you see an image of your phone on a large screen, it's likely that this mode is activated.
Another option is Bluetooth connectivity, which is often used to manage presentations, transfer audio files, or use a smartphone as a remote control. Unlike Wi-Fi, a Bluetooth connection may be less visible visually, but it continues to consume resources from both devices.
The third type of communication is through remote applications, such as MI Remote or Google Home. In this case, the physical connection can be severed, but the program communication through a Google account or Mi Account remains active, allowing the phone to control the TV when on the same network.
- 📱 Wireless broadcast: Full mirroring of the smartphone screen on the TV via Wi-Fi.
- 🔵 Bluetooth Communication: Transfer audio, files, or use your phone as a remote.
- 🏠 Local area network: Control via remote applications within a single Wi-Fi network.
- 🌐 Online Accounts: Connecting via Google or Xiaomi Cloud Services.
⚠️ Warning: Before turning off, make sure that the TV does not update the system software, as a break in communication with the server or phone source firmware can lead to a software failure.
Understanding the type of connection is the first step to solving the problem, so if you just turn off the Wi-Fi on your phone, but keep Bluetooth active, the TV can continue trying to connect through a backup channel, so it's important to check the status of all wireless interfaces.
Disconnection through the broadcast menu on a smartphone
The fastest way to break the connection is to use the standard means of the Android operating system installed on your phone. the interface may vary slightly depending on the OS version and the MIUI or HyperOS shell, but the logic of actions remains the same for all devices.
You need to deploy the Quick Settings Panel by swiping from top to bottom across the screen. Find an icon called Translation, Translation, Cast, or Wireless Monitor. If you're connected to a Xiaomi TV, this icon is usually lit up or has a "Connected" label.
Click on the active control. You'll see the list of available devices or the current status of the connection. To turn off, just click on the "Disable" button or select "Stop broadcasting." The system will immediately break the video stream and audio channel.
☑️ Pre-switch check
In some cases, especially when using third-party launchers, the broadcast icon may be hidden, then go to the full settings menu, find the Connections and Sharing or Connected Devices section, and you will need to find the Broadcast or Wireless display item inside.
Once you log in, you'll see a list of previously used devices. Find your Mi TV or Xiaomi TV in the list. Click on the device name and select the "Forget" or "Disable" option. This action will not only interrupt the current session, but also remove the trust profile, preventing automatic reconnection in the future.
If the standard menu is unresponsive or the shutdown button is inactive (painted in gray), try temporarily turning on and off In-Air mode, which will force you to restart all wireless modules and reset the suspended connections.
Device management in Xiaomi TV settings
It is not always convenient to reach for the phone, especially if it is in another room or is discharged. In such cases, the connection can be controlled directly from the remote control of the Xiaomi TV. Android TV or PatchWall interface provides enough tools to control the connected gadgets.
Go to the main menu of the TV and go to the Settings section (cog icon), you need to find the item responsible for network and connections, depending on the model, it can be called Network and Internet, Connected devices or Preferences.
Inside the menu, look for Broadcast or Google Cast, which shows a list of devices that currently have access to a TV screen or are in standby mode, and select your smartphone from the list.
When you select the device, you'll see a context menu, and you'll need to select "Disable" or "Stop session." If you want to completely stop this phone from connecting in the future, select "Delete device" or "Forget." MAC-phone address blacklisted or just clear the pairing cache.
| Model TV Xiaomi | The way is on the menu | Name of function | Action. |
|---|---|---|---|
| Mi TV Stick 4K | Settings -> Applications -> Google Cast | Turn on receiver | Turn off the switchboard |
| Mi TV P1 | Settings -> Network and Internet -> Broadcast | Screen broadcasting | Shut down. |
| Xiaomi TV A2 | Settings -> Preferences -> Connected devices | Device management | Forget the device |
| Mi Box S | Settings -> Applications -> All Apps -> Chromecast | Clear the data | Cache dumping |
What if the TV doesn’t see the switch off button?
Also pay attention to Bluetooth settings if the phone is connected as an audio device or remote. Go to Settings -> Remote and Accessories (or Bluetooth). Find your phone in the list of paired devices, click on the gear icon or information icon next to the name and select "Unpair."
Set up a router and Wi-Fi network
If the wireless connection between a Xiaomi phone and TV is via a local Wi-Fi network, the most radical and effective way to break the connection is to change the network parameters, which is especially true if the devices stick to each other and connect automatically without your knowledge.
The first is to split networks, make sure your phone and TV are connected to different frequency bands of the router, if you're configured. Many modern routers connect networks. 2.4 GHz and 5 GHz under one name, divided into Home_2.4G and Home_5G And by connecting devices to different names, you can limit their visibility to each other depending on the isolation settings.
A more advanced method is to use AP Isolation or Client Isolation in router settings, which prevents devices connected to the same Wi-Fi network from communicating with each other, and the phone simply won’t see the TV in the list of available devices for broadcasting.
To access these settings, you will need to log into the router’s web interface, usually via a browser at 192.168.0.1 or 192.168.1.1. The login and password are often listed on a sticker at the bottom of the router.
- 🔒 Guest Network: Connect your TV to your guest Wi-Fi network and leave your phone on the main one. Guest networks are by default isolated from local devices.
- 🚫 Filtration MAC-Addresses: In the router settings, you can prevent a particular device from accessing the network or other devices.
- 📶 Shutdown DLNA: In the router settings (Media Server section) you can disable the transfer of multimedia between clients.
⚠️ Attention: Enabling customer isolation (AP Isolation can disrupt the smart home.Light bulbs, sockets and other IoT devices may stop responding to commands from a smartphone, as they will lose the ability to exchange data packets on the local network.
If you don't want to get into your router's settings, you can just forget the Wi-Fi network on one of your devices. Go to your TV's Wi-Fi settings, select your home network, and click "Delete Network" or "Forget." The TV will stop receiving. IP-The address will become invisible to the phone on the local network.
Resetting settings and removing pairing profiles
In situations where standard disconnection methods don't work, or the connection occurs over and over again due to software errors, deeper cleaning of the pairing profiles is required. This is not a complete reset of the TV to factory settings, but only the removal of accumulated data about trusted devices.
On Xiaomi TVs with Android TV shell, accumulated cache data of the broadcast applications can cause conflicts. Go to Settings -> Apps -> All Apps. Find the Chromecast built-in or Wireless Display system application on the list.
Log in and select Memory (or Storage). Press Clear Cache and, if the problem persists, Clear Data. This action will reset all the settings of the broadcast receiver, and the TV will look like a new device for your phone. All previously saved phones will be "forgotten."
💡
Before clearing system application data, take a photo of a list of important Wi-Fi passwords or network settings if they are stored in the TV’s memory, although they are usually stored in the system partition that is not affected by the application cache cleaning.
If the problem is Bluetooth, the profile list needs cleaning as well. Go to Settings -> Remotes and Accessories. You'll see a list of all devices ever connected. Click on every unwanted device (especially old phones) and select Unpair.
As a last resort, if a software failure does not allow you to turn off the phone in any way, you can reset your network settings. On some Mi TV models, this option is available in the About Device section -> Reset -> Reset network settings. This will return the Wi-Fi and Bluetooth settings to factory values, but will not delete your installed applications and accounts.
Use of third-party applications and commands
For advanced users who aren’t afraid to experiment, there are more subtle connectivity management tools available. If Xiaomi’s built-in menus don’t seem informative enough, you can use third-party software to analyze and break connections.
One effective way is to use network management applications like Fing or Network Analyzer installed on a smartphone, which let you see all the devices on the network. Although they are primarily diagnostic, some have the function of blocking access to certain types of devices. IP-Addresses that will actually turn off the phone from the ability to "knock" on the TV.
You can also take advantage of Android itself through developer mode. If your Xiaomi TV is enabled with developer mode (activated by seven times tapping the build number in the About Device menu), you can access debugging.
However, for the average user, a safer and simpler method is to use remote applications with advanced functionality. For example, the Google Home app allows you to control Chromecast devices. Open the app, find your TV, click on the settings icon (cogs) and select “Stop streaming” or remove the device from the list of “Home devices”.
