How to sync your Samsung phone with your Xiaomi TV over Wi-Fi

The modern smart home ecosystem is often built on devices from different manufacturers, and the bundle of Samsung’s smartphone with Xiaomi TV is one of the most popular combinations on the market. Users often wonder whether it is possible to efficiently transfer content from the phone screen to the large display without using wires. Fortunately, wireless data technologies such as Miracast and DLNA allow you to do this natively, without installing complex third-party software. Samsung owners have the advantage of the built-in AllShare Cast (or Smart View) protocol, which works well with the Android TV or PatchWall operating system on Xiaomi TVs.

Synchronization doesn’t require much technical knowledge, but there are some nuances that can affect connection quality. The stability of your video stream depends on the configuration of your local network and the software version of both devices. If you want to enjoy 4K movies or play mobile games on the big screen, it’s important to make sure that both devices are on the same network and use current encryption standards. In this article, we’ll take a closer look at all the available connectivity methods.

It's worth noting that some users confuse simple remote control and full image broadcasting. We'll look at both scenarios because they solve different problems. Control via Mi Remote is convenient for navigating menus, whereas Smart View is necessary for multimedia. Understanding the difference will help you choose the best way to interact with the technology.

Technical requirements and equipment preparation

Before setting up, make sure your hardware meets the minimum requirements for stable wireless interfaces. Xiaomi TVs running on Android TV are usually equipped with a Wi-Fi module with support for 2.4 and 5 GHz. For heavy video streaming in high resolution, it is highly recommended to use the 5 GHz band, as it is less loaded and provides higher bandwidth.

Samsung smartphones must support the Smart View feature, which is built into the One UI shell starting with certain versions of Android. Usually these are Galaxy S, Note and A series devices released in the last 5-6 years. Check if your phone's software is updated to the latest available version, as older Wi-Fi Direct drivers can cause connection errors.

⚠️ Warning: Make sure your router does not activate the function «AP If this option is enabled, devices connected to Wi-Fi will not “see” each other, and synchronization will become impossible.

It is also important to check for free space in the TV’s RAM. The PatchWall or Android TV system can run slowly if the cache is full, which will lead to delays (lags) when displaying the image from the phone. Before the active phase of setting up, it is advisable to reboot both devices to reset temporary network errors.

Use the built-in Smart View feature on Samsung

The easiest and fastest way to stream the screen is to use the native Smart View feature, which is built into the smartphone’s Quick Settings Panel and does not require additional apps to be installed. The technology is based on the Miracast standard, which allows you to create a direct connection between devices without the need for a complex router configuration.

To activate the feature, lower the notification curtain on your Samsung and find the Smart View icon. Once pressed, the phone will start scanning available devices within range. Your Xiaomi TV should appear on the list (often displayed as an Android TV or model, such as Xiaomi TV 4S). Click on the name and a connection permission request may appear on the TV screen, which must be confirmed by the remote control.

The quality of the image in this mode depends on the power of the phone's processor and the speed of the Wi-Fi module. If you notice the desynchronization of sound and video, try to reduce the output resolution in the Smart View settings. Also, it is worth considering that in mirror mode the phone is not recommended for other tasks, as this can cause the interface to slow down.

💡

To reduce the latency of sound in games, use wired headphones connected to the phone or an external Bluetooth headset, as audio transmission over Wi-Fi can have lags of up to 200 ms.

Set up Xiaomi TV to receive the signal

While modern Xiaomi TVs are often ready to connect out of the box, you sometimes need to manually activate the signal reception mode. Depending on the firmware version (Android TV or the Chinese version with PatchWall), the path to settings may differ.

Go to the settings menu of your TV and go to Settings → Network & Internet → Wi-Fi Direct (or similar to Wireless Monitor). Make sure the feature is enabled. Some Xiaomi models require you to run a special application called “Wireless Display” or “Mi Cast” that puts the TV in standby mode.

If the TV doesn't show up on the list of available devices on your phone, try changing the device name in your TV network settings. Sometimes Samsung smartphones don't see devices with names that contain special characters or Cyrillic. By renaming the TV in Latin, you can solve the visibility problem.

Alternative methods: Google Home and Chromecast

Since most Xiaomi TVs are Android TV certified or have a built-in Chromecast built-in, you can use the official Google Home app, which often works more consistently than Miracast, especially when streaming content from apps like YouTube or Netflix, as it uses the DIAL protocol.

Install the Google Home app on your Samsung from the Play Market Store. Once launched, the app will automatically find a Xiaomi TV on the same Wi-Fi network. Select your device and click the "Cast screen" button. Unlike Smart View, the phone can only act as a remote control, and the video is downloaded directly from the TV, saving battery power.

The advantage of this method is that it supports high resolution and adaptive bitrate. If the Internet channel is narrow, the Chromecast will automatically lower the picture quality to avoid buffering, whereas in Miracast, the phone will try to transmit the stream in its original quality, causing jerks.

Controlling TV through Mi Remote app

Special attention should be paid to the scenario where you don’t need to broadcast the screen, but just control the TV from your phone. This is the perfect application Mi Remote (or built-in “Mi Remote” in Xiaomi phones, but for Samsung it is better to download Mi Remote Controller from the Play Market), which turns your smartphone into an advanced touchpad and keyboard.

Once paired with Wi-Fi, you get full access to the TV interface, which is especially useful for typing text when searching for movies or in the browser, because the virtual keyboard on the phone screen is much more convenient than navigating with the remote buttons. The application also allows you to transfer files (photos, videos) to the TV for later playback.

Importantly, Mi Remote doesn’t require the phone and TV to be on the same network if you use an infrared port (which most modern Samsung doesn’t), but Wi-Fi extends the functionality, you can even turn off the TV or run apps with voice through the Google Assistant on the phone.

To make it easier for you to choose the right way, we have systematized the main characteristics of synchronization methods in the table below.

As you can see from the table, the best way to view photos and videos from the gallery is using a local network without constant coding of the stream, but Smart View is indispensable for games or desktop demonstrations.

Troubleshooting and troubleshooting

Despite the ease of setting up, users may encounter problems, one of the most common is that the TV is visible but the connection is reset. IP-Try restarting the router and changing the broadcast channel in its settings to a less loaded one (for example, 1, 6 or 11 for 2.4 GHz).

Another problem is that there is no sound when you successfully broadcast an image, so check the settings in the Settings → Sound menu on your TV. Sometimes the system defaults on the wrong audio output. Also make sure that the phone does not have Do Not Disturb mode, which can block system sounds.

⚠️ Warning: If the image twitches or is low resolution when connected, get closer to the router. wireless protocols are sensitive to physical obstacles such as concrete walls.

In case nothing helps, reset the network settings on both devices. On Samsung, this is done via Settings → General → Reset → Network settings. On Xiaomi TV, you can reset through the Restore Menu or by removing the device from the list of paired devices in the Wi-Fi Direct settings.

💡

90% of connection problems are solved by restarting the router and checking that both devices are on the same subnet (the same range). IP-address).
