The situation when the screen broadcast on the Xiaomi TV stops suddenly or does not start at all is familiar to many users of the ecosystem: you try to bring a photo, video or presentation to the big screen, but nothing appears on the list of available devices, or the connection is terminated after a few seconds, which is annoying, especially when you urgently need to show content to guests or launch a movie.
Problems with Mi Drop, built-in Translation, or third-party apps like YouTube are often rooted in trivial network settings or software conflicts. Android on Xiaomi smartphones (MIUI or HyperOS) has its own peculiarities of working with network protocols that can block the detection of external displays.
In this article, we will take a closer look at all possible causes of failure, from differences in Wi-Fi frequencies to hidden power saving settings, learn how to diagnose the problem yourself without resorting to complex engineering menus, and restore seamless communication between gadgets.
Basic requirements and compatibility of Wi-Fi networks
The most common mistake that 90 percent of users face is finding devices on different subnets. To work properly, Miracast or DLNA technology, your Xiaomi smartphone and TV must be connected to the same access point. It would seem simple, but routers often have two frequency bands.
Modern routers broadcast the signal in the ranges 2.4 GHz 5 If your Xiaomi Mi is TV net-connected «Home_5G», And the phone is in range «Home_2.4», They may not see each other despite having the same router password. Some routers isolate these threads, preventing local communication between clients.
It’s also worth checking if the router has Guest Network activated, and devices connected via a guest profile often have a software ban on interacting with other devices on the LAN for security reasons.
⚠️ Note: If you use a mobile hotspot (spreading the Internet from your phone), the built-in screen broadcast function may not work, since the Wi-Fi module is busy transmitting data, not receiving a signal from the TV.
Configure the Translation function and connection protocols
In the MIUI shell and the new HyperOS, the system service is responsible for displaying the image, which can be hidden or disabled by default. To initiate a connection, you need to lower the notification curtain and find the Translation icon (sometimes called Translate or Caste) and if the icon is not present, you can add it through the Quick Settings Editing menu.
Once the search is launched, the phone starts scanning for devices that support Wi-Fi Direct or Chromecast built-in. If the Xiaomi TV is on but is in sleep mode, it may not respond to detection requests, in which case you need to take the remote and wake the screen.
☑️ Device search algorithm
It is important to consider that some TV models require manual permission to connect. When you select your TV in the list, a pop-up window may appear on the TV screen asking: "Allow connection from a Xiaomi device?" If you do not click "Accept" for 15-30 seconds, the connection will be reset.
Owners of Android TVs (PatchWall) sometimes require you to activate reception in the settings of the TV itself.The path may differ, but it is usually in Settings → Network and Internet → Connection settings. Make sure the options "Screen copy" or "Miracast" are enabled.
Problems with Google drivers and system services
Many of the features of Android media are based on Google Play. If your Xiaomi smartphone only has basic services installed or there is a bug update to Google components, the streaming feature may not work properly, especially when streaming from apps like YouTube or Netflix.
Often, the problem is solved by clearing the cache of system services, you need to go to your phone settings, select the "Apps" section, then "All Apps" and find "Google Play Services." Inside the app menu, you need to select "Memory" and click "Clear Cache" This will not delete your data, but update the temporary service files.
| System component | Function | Impact on broadcasting | Failure action |
|---|---|---|---|
| Google Play Services | Basic API Integration | Critical for Chromecast | Update or reinstall |
| Systemic UI | Curtain interface | No start button | Add to Quick Settings |
| Wi-Fi Direct | Direct connection | Basic image transmission | Reset the network settings |
| Bluetooth | Searching for devices | Helps in the primary conjugation | Energize on both devices |
It’s also worth checking for updates for the app itself you’re trying to stream. For example, if YouTube doesn’t work, go to Google Play Market, find the app, and click Update. Outdated versions can use old protocols that modern TVs no longer support.
Impact of energy saving and background processes
The aggressive battery saving policy in MIUI/HyperOS is a frequent enemy of stable connectivity. The system can kill the broadcast process, considering it a background task consuming too much power, which leads to the picture appearing, but after a minute it goes out or begins to slow down.
To rule out this factor, you need to configure exceptions for system services. Go to Settings → Battery and Performance (or simply “Battery”). Find the Translation or System Components app and set the “No Limits” mode, which will prevent the system from turning off communication modules to save energy.
Why is the broadcast interrupted when the screen is turned off?
Another nuance is that Do Not Disturb or Airplane mode is working. While you can manually turn on Wi-Fi in flight mode, some system services responsible for detecting devices on the local network may remain locked, and it is better to turn off flight mode completely before the session begins.
⚠️ Attention: When broadcasting, the phone can get very hot, which is a normal reaction of the processor to encoding the video stream in real time, but it can provoke trottling and image lags.
Software version conflicts and firmware updates
The mismatch between the software versions on your phone and TV is a hidden but serious problem. If your Xiaomi Mi Box or TV runs on an older version of Android TV and your phone is upgraded to the latest HyperOS, the handshake protocols may not match.
Check for updates for your TV. Go to Settings → About TV → System Update. Often, manufacturers will issue patches that fix compatibility issues with new smartphones. It’s also worth checking the About Phone section for available MIUI updates on your phone.
💡
If you don't have automatic updates on your TV, try changing the region in your TV settings to China or India, check for updates, and then return your region, sometimes forcing you to search for servers.
In rare cases, a complete reset of network settings on a smartphone helps, which will bring all the parameters of Wi-Fi, Bluetooth and mobile networks back to factory values. You will have to re-enter passwords from Wi-Fi, but this often “cures” software glitches of the protocol stack.
If the problem arose after a recent firmware update, there may be a bug in the new version, which is why you should look up information on Xiaomi user forums. Often engineers release hotfixes within a couple of weeks of detecting mass complaints.
Use of third-party broadcasting applications
When Xiaomi’s regular funds fail, third-party solutions come to the rescue, and apps like LetsView, ApowerMirror, or Web Video Caster use their own data algorithms and are often more stable than the built-in feature.
Most of these apps require a client to be installed not only on the phone but also on the TV (via the Google Play app store on TV), and they work in a simple way: they create their own communication channel, bypassing the standard system limitations of MIUI. This is especially useful for older TV models that do not support modern codecs.
However, it is worth remembering the delay. Third-party applications can add a lag of 1-3 seconds between the action on the phone and the display on the screen. For viewing photos or videos, this is not critical, but for games or presentations in real time, this delay can be noticeable.
💡
Third-party apps are a great temporary solution if the standard Translation feature is damaged after the update, but they require additional software to be installed on both devices.
