Why the phone does not see the Xiaomi TV: reasons and solutions

When a smartphone refuses to detect a Smart TV, it often takes you by surprise, especially if you were planning to watch a movie or show photos to guests. The problem when the phone does not see a Xiaomi TV can arise for a variety of reasons, from banal desynchronization of Wi-Fi modules to deep system conflicts of data protocols. Device owners often sin on “curve” firmware, but in 90% of cases it lies in the settings of the router or the security parameters of the local network.

Before you panic and bring the equipment to the service, you need to conduct a basic diagnosis. Mi TV and Android smartphones use standard broadcast protocols such as Miracast, DLNA or Chromecast, which require strict connection conditions. If any of the conditions are violated, the devices simply stop “seeing” each other in the list of available receivers.

In this article, we will take a look at the algorithms that will help you restore the connection, and we will look at not only software settings, but also network nuances that are often overlooked, and understanding how the LAN works will help you quickly fix the malfunction without reinstalling the system.

Basic requirements for Wi-Fi network

The most common reason a phone can't find a TV is because it physically divides devices into different subnets, and for Screen Cast to work properly, both devices must be on the same LAN, which means they must be connected to the same router.

But there's a big nuance that many people forget about, and modern routers often operate in two bands: 2.4 GHz 5 GHz. Despite the fact thatSSID (The network name may be the same, the router may isolate customers of different bands from each other. Home_5G, and phone to Home_2.4, The search may not yield results.

It’s also worth checking the guest network settings, which means that if one of the devices is connected to the guest Wi-Fi, it will be isolated from the main pool of devices for security reasons, in which case client isolation prohibits the sharing of data between gadgets, even if they belong to the same owner.

Make sure both devices have Wi-Fi and Bluetooth enabled. Although video streaming is over Wi-Fi, Bluetooth is often used for initial device detection and pairing.Switching off Bluetooth on a smartphone can prevent the TV from appearing on the list of available devices.

Configure the “Translation” function on the TV

Even with a perfect network, the TV can remain invisible if the signal reception function is turned off on its side. On Xiaomi Mi TVs, this option can be turned off by default or lost after a system update. You need to manually activate the connection standby mode.

Go to the settings of the TV via the remote. Find the partition responsible for connections or network. Depending on the version of the PatchWall shell or Android TV, the path may differ. You usually need to go to the application menu and find the system utility for wireless connectivity.

⚠️ Note: On some Xiaomi TVs, the broadcast function is not automatically activated when the TV is turned on. It must be manually started each time before connecting, unless the settings are auto-start.

Procedure for activation of visibility mode:

• 📺 Click the “Menu” button or go to the main screen.
• 📡 Find the Wireless Display, Miracast or Translation app».
• ✅ Launch the application and wait for the message “Ready to connect” to appear».
• 🔍 Now try to start a search from your phone.

If a countdown timer or device name appears on the TV screen after the app is launched, but the phone is still silent, the problem may be the protocol version. Older phones may not see the new Miracast standards, and vice versa, in which case the use of third-party intermediary apps helps.

Checking the settings of the smartphone

When the TV is ready to receive the signal, but the smartphone stubbornly ignores its presence, you should pay attention to the settings of the phone itself. First of all, check whether the Incognito mode for Wi-Fi is turned on. Android 10 and later has a randomization feature. MAC-addresses that sometimes conflict with router or TV security filters.

Try to forget the Wi-Fi network on your phone and reconnect, which will reset the cached network settings and force the device to shake hands with the router again, and make sure that the phone does not have Traffic Saving or Flight Mode, which can block the background search of devices.

💡

Before searching for a TV, completely close applications that consume a lot of traffic (torrents, downloads), as they can block the ports necessary for discovery protocols.

There's a different nuance for Xiaomi and Redmi users: there are severe back-end limitations in the MIUI or HyperOS shell, and if the system finds it too energy-intensive, it can put it to sleep. Go to the battery settings and let the Translation or Mi Remote app run in the background without restrictions.

There's also a hidden setting in the developer menu that affects visibility. If you've ever turned on developer mode, check the "Enable Wireless Debugging" option, sometimes activating it changes the priorities of network queries.

Use of the Mi Home app and Google Home

If you can't find a TV by standard means, you can use proprietary ecosystems. Mi Home and Google Home have their own devices on the local network, which often work more stable than the tools built into Android.

Mi Home is ideal for PatchWall TVs, and uses its own detection protocol, which is less dependent on standard Android services. Once you add the TV to the app, you can stream content directly from the interface.

For TVs with pure Android TV, Google Home is better. This app lets you control your device like a Chromecast. If Google Home sees a TV, then there is a physical connection, and the problem lies in the specific application from which you are trying to run the video (for example, YouTube or VLC).

It’s important to make sure that both devices (phone and TV) have up-to-date versions of these apps, and older versions may not support the new security protocols Google or Xiaomi have implemented in the latest firmware updates.

Resetting network settings and restarting

Network errors are a common cause of failures, and over time, conflicts can occur in the cache of the router and end devices. IP-addresses or errors DNS, A simple but effective method is to completely reset the network settings.

Not to be confused with a full factory reset, you need to find Reset Network Settings, which will remove stored Wi-Fi passwords, Bluetooth and VPN settings, but will return the network modules to factory status, which often solves the problem.

It is also critical to perform the correct reboot sequence of equipment: not just turn the devices off and on, but do it in a specific order to clean up. ARP-router-table.

⚠️ Warning: Do not pull the router plug out of the socket immediately after switching off. 10-15 seconds, so that the capacitors are discharged and the RAM is completely cleared.

The correct reboot algorithm:

1. Turn off the TV and your smartphone.
2. De-energize the router (pull the power cord).
3. Wait 30 seconds.
4. Turn on the router and wait for the full load (2-3 minutes).
5. Turn on the TV, then your smartphone.

Protocol compatibility and third-party solutions

Sometimes the problem is that software implementations are incompatible, like trying to stream video in a format that doesn't support the TV's built-in decoder, or using a protocol that's locked at the firmware level, and in those cases, third-party solutions come to the rescue.

Installing a mediator app on a TV can make a difference, with popular programs like AirScreen or Receiver for Chromecast emulating native protocols, making the TV visible to any device, even if Xiaomi’s native system is “capricious.”

Below is a table of compatibility of the main connection methods for different scenarios:

If none of the software methods work, you should consider buying a physical adapter, such as a Chromecast or Apple. TV, plug-in HDMI-This completely eliminates the programming conflicts of the TV's internal system.

💡

Using a third-party receiver app on a TV (like AirScreen) is often the only way to make streaming work on older or problematic Xiaomi TV models.
