Modern users often face the need to display content from their smartphones on a larger screen. Owners of the bundle Xiaomi And Samsung Both companies are well positioned for this, as both companies are actively implementing wireless data transmission standards. Establishing a connection between devices may seem complicated at first glance, but in practice, it takes just minutes with the right setup.
The basis for successful synchronization is a stable local area networkIf your router is working properly and your devices are within a strong reception area, you can enjoy photos, videos, and games in full screen without lag. In this article, we'll cover all available options, from built-in features to specialized software.
There are several transmission protocols such as Miracast And DLNA, each with its own characteristics. Understanding the differences between them will help you choose the optimal method for a specific task, whether it's watching a movie or presenting a presentation.
Preparing equipment and network
Before you begin setting up the streaming service, you need to ensure that both devices have the same connection conditions. This is a fundamental step, and ignoring it causes 90% of all device detection issues. Make sure both your phone and TV are connected to the same network. Wi-Fi networks.
Pay attention to the signal frequency. If your router broadcasts the network on 2.4 GHz and 5 GHz frequencies under different names, both devices should be connected to the same one. Mixing bands can sometimes block devices from being detected on the local network.
- 📡 Check that Wi-Fi is enabled on both devices.
- 🔗 Make sure that the network names (SSID) on your phone and TV are identical.
- ⚡ Disable mobile internet on your smartphone to avoid routing conflicts.
- 🔄 Restart your router if the connection is unstable or drops.
⚠️ Note: If you're using a guest Wi-Fi network with client isolation enabled, devices won't be able to see each other. Use your main home network.
It's also worth updating the software. On TVs Samsung with the operating system Tizen and smartphones Xiaomi with shell MIUI or HyperOS Regular updates often contain fixes to communication protocols.
Using the built-in Smart View feature
The most universal and frequently used method is technology Smart ViewOriginally developed by Samsung, it is now supported by other manufacturers, including Xiaomi, via standard Android protocols. This method allows for real-time image streaming.
To get started, open the notification shade on your smartphone. XiaomiLook for the "Cast," "Wireless Monitor," or "Cast" icon. In newer firmware versions, it may simply be called "Cast."
Once the feature is activated, the phone will begin searching for available displays on the network. When yours appears on the list Samsung TV, tap it to pair. A connection permission prompt may appear on the TV screen, which you'll need to confirm with the remote.
- 📺 The image from the phone is completely duplicated on the TV screen.
- 🎮 Suitable for gaming and navigating smartphone menus.
- 🔋 May drain your mobile device's battery faster.
- 📉 Picture quality depends on the strength of the Wi-Fi signal.
It's important to note that this method doesn't turn off your phone's screen. If you just want to watch videos, it's better to use the built-in features of the video players themselves, which we'll discuss below, to save battery life.
☑️ Check before connection
Broadcast via the Google Home app
If the standard system tools don't find the TV or work unstably, the official application comes to the rescue. Google HomeThis is Google's central smart home control platform that works great with TVs. Samsung, which have built-in Chromecast.
Install the app from the store Google Play and log in to your account. The program will automatically scan the network and find connected devices. Select your TV from the list of available devices.
In the control menu that opens, click the "Cast screen" button. This will start the mirroring process. The advantage of this method is its high stability and support for Google codecs.
⚠️ Note: For Google Home to work on your Samsung TV, Chromecast built-in must be enabled. Older models (pre-2019) may not have this feature.
The app not only allows you to mirror your screen but also control media. You can adjust the volume, pause videos, or launch background slideshows from Google Photos without having to actively use your phone.
What to do if Google Home doesn't see the TV?
Make sure the same Google accounts are used on your phone and TV (although this isn't always necessary for basic streaming). Try clearing the Google Home app cache in Android settings. Also, check if your router's firewall is blocking the ports required for discovery protocols (usually UDP 1900).
Streaming videos from YouTube and online cinemas
The scenario of viewing content from applications deserves special attention. When you launch a video in YouTube, Netflix or Kinopoisk On your phone, using screen mirroring is inefficient. It results in reduced quality and unnecessary resource consumption.
Instead, use the built-in "Broadcast" feature (the rectangle icon with waves). Tap this icon in the app on your phone. Xiaomi. Select your TV Samsung from the list.
In this case, the phone acts only as a remote control. The video is buffered and played directly from the internet by the TV. This ensures maximum picture quality, up to 4K, and allows you to use the phone for other tasks.
| Parameter | Mirroring (Smart View) | Broadcast from the app (Cast) |
|---|---|---|
| Signal source | Phone processor | Internet (directly to TV) |
| Battery consumption | High | Short |
| Multitasking capability | No (screen is busy) | Yes (you can use the phone) |
| Image quality | Depends on Wi-Fi | Maximum (original) |
This method is ideal for long movie viewing sessions. It frees up your smartphone and ensures that an incoming call won't interrupt playback on the big screen, but merely pauses it.
Third-party applications for complex cases
Sometimes built-in tools fail, especially when you need to stream content from apps that block screen recording, or when an older TV model doesn't support modern protocols. In these cases, third-party solutions come to the rescue.
One of the most popular applications is Web Video CasterIt allows you to send videos from websites directly to your TV, bypassing the limitations of mobile browsers. The app is available in the store. Google Play and requires installation of the server part on some TV models, although Samsung often works without it.
Another powerful tool is AllCastThis app specializes in transferring media files (photos, videos, music) from your phone to DLNA-compatible devices. It has a user-friendly interface and supports various file formats.
- 📂 Supports a wide range of video formats, including MKV and AVI.
- 🖼 Possibility to create a slideshow from the gallery.
- 🎵 Stream music in the background.
- ⚙️ Flexible bitrate and resolution settings.
Using third-party software requires careful consideration of permissions. The app must be granted access to the local network and files, otherwise it won't be able to find the TV or play content.
Communication solution and optimization
Even with proper setup, technical difficulties can still arise. Most often, users complain of audio and video desynchronization or intermittent image flickering. These are clear signs of bandwidth issues.
Try moving the router closer to your TV or using a wired connection for the TV, if possible. A stable wired connection for the receiver (TV) significantly improves the quality of wireless transmission from the source (phone).
⚠️ Note: Menu interfaces and function names may vary depending on the Tizen firmware version on your TV and the MIUI/HyperOS version on your phone. If you can't find the option described, use the settings search.
If the image is streaming but there's no sound, check your Android sound settings. Make sure "TV Speaker" or something similar is selected as the output device, not "Phone Speaker."
If the connection keeps dropping, reset the network settings on both devices. On the TV Samsung this is done through Settings → Support → Self-diagnosis → Reset Smart Hub (Be careful, this may reset app passwords). On the phone Xiaomi It is enough to forget the Wi-Fi network and connect again.
Why doesn't the TV detect my Xiaomi phone?
Most often, the problem stems from devices connected to different router frequencies (2.4 GHz and 5 GHz) with different network names. Another possible cause could be an enabled VPN on the smartphone, which hides the device from the local network, or router firewall settings that block discovery protocols.
Is it possible to broadcast a screen without the internet?
Yes, Miracast (Wi-Fi Direct), the technology used for mirroring, doesn't require internet access. The devices create a direct connection between each other. However, internet access is required for streaming from YouTube or online movie theaters.
Does broadcasting affect internet speed?
When using the Cast method (from the app), traffic goes directly from the server to the TV, without loading the phone's bandwidth. When mirroring, the entire video stream goes through the phone and router, which can consume a significant portion of the Wi-Fi channel's bandwidth.
