Modern Samsung TVs with Smart TV function are powerful multimedia centers, but controlling built-in applications via the remote control often seems inconvenient. Entering text using the navigation buttons takes a lot of time, especially when you need to find a specific video or enter your username to log into your account. Using a smartphone-based Android as a remote control solves this problem and opens up access to more flexible scenarios for using content.

There are several proven ways to broadcast video from a mobile device to a large screen, each of which has its own characteristics. You can use the built-in function Smart Viewthat works via the Wi-Fi Direct protocol, or use the classic pairing method via a QR code inside the YouTube application itself. Understanding the difference between simple broadcast (cast) and screen mirroring will help you choose the best option for your situation.

In this article we will analyze in detail the technical nuances of each method, consider possible connection errors and ways to eliminate them. Regardless of which version of the operating system is installed on your phone - Android 10, 11 or a more recent Android 13 - you can easily enjoy content on the big screen. The main thing is that both devices are on the same local network or have an active Internet connection for cloud functions to work.

Hardware and network infrastructure requirements

Before you start setting up, you need to make sure that your equipment meets the minimum technical requirements. First of all, we are talking about the TV's support for technology Smart TV. If you have an old model without an intelligent platform, connection is only possible through external set-top boxes, such as Chromecast or Android TV Box, which take on the role of a signal receiver.

A critical condition is the presence of a stable network Wi-Fi. Both devices—the smartphone and the TV—must be connected to the same wireless network. If your router supports dual-band operation (2.4 GHz and 5 GHz), make sure that the gadgets are not spread across different frequency bands with isolation of clients, otherwise they simply will not “see” each other on the local network.

  • 📱 A smartphone or tablet running an operating system Android version 5.0 and above.
  • 📺 TV Samsung with support for Smart TV (J, K, M, N, Q, LS series and newer).
  • 📡 Stable Internet connection with a speed of at least 5 Mbit/s for HD video.
  • 🔋 The smartphone battery charge is above 20% or connected to a power source.

It is worth noting that the playback quality directly depends on the bandwidth of your channel. When broadcasting video in high resolution 4K Ultra HD the load on the network increases many times, so using the 5 GHz band is preferable to minimize buffering and delays.

⚠️ Attention: Some corporate or public Wi-Fi networks may block device discovery protocols (DLNA/UPnP). In such cases, standard connection methods may not work, and you will need to use a mobile hotspot.

Also check that the software is up to date. On a Samsung TV, this can be done through the menu Support → Software update. On your smartphone, make sure that the application YouTube has been updated to the latest version through the store Google Playas older versions may not have the necessary drivers for casting.

Smart View method: native integration of Samsung and Android

The fastest and most convenient way for owners of Samsung equipment and most modern Android smartphones is to use technology Smart View. This function is built into the shell One UI and allows you to mirror the screen or broadcast content without installing additional applications. The operating algorithm is based on searching for available devices on the local network.

To activate the function, lower the notification shade on your smartphone by swiping from top to bottom. Look for the Smart View icon (sometimes it may be called “Cast” or “Screen Sharing” depending on the phone manufacturer). After clicking, the system will begin scanning for available receivers. When your TV appears in the list Samsung, click on it to pair.

After successful connection, the image from the smartphone will be completely displayed on the TV screen. In this mode, the phone acts as a video source, and the TV is just a monitor. This means that you can open any application, browser or gallery, and everything will be visible on the big screen, which expands the usability.

However, this method has its own characteristics. Screen mirroring may cause your smartphone to run out of battery faster, and there may be slight delays in audio and video transmission, especially if the Wi-Fi network is congested. This is an ideal option for viewing photos or presentations, but for games with high dynamics it may not be suitable due to Input Lag.

  • 🔄 Complete mirroring of the smartphone screen on the TV.
  • 🎮 Ability to control content directly from the phone's touchscreen.
  • 🔊 Sound transmission through TV speakers or a connected acoustics.
  • 📉 Possibility of increased smartphone battery consumption.

If you want to display only the video from YouTube, and not the entire screen, launch the video in the application, click on the broadcast icon and select “Smart View”. In this case, the YouTube application on the phone will work as a remote control, allowing you to minimize it and do other things while the video is playing on the TV.

Using the broadcast button inside the YouTube application

The classic and most stable method is to use the built-in cast function in the application itself YouTube. This method does not require mirroring the entire screen, which saves smartphone processor and battery resources. The video is buffered directly by the TV, and the phone only sends control commands.

Open the YouTube application on your Android device. In the upper right corner of the interface you will see a characteristic rectangle icon with Wi-Fi waves in the corner - this is a Broadcastbutton. Click on it. The application will offer a list of available devices. Select your TV Samsung from the list.

After connecting, the player control panel will appear at the top of the smartphone screen. Now you can minimize the YouTube app, reply to instant messages, or even lock the screen without interrupting playback on your TV. This is a key difference between this method and Smart View, where the active application often needs to be kept open.

⚠️ Attention: If the cast button is gray or inactive, check whether Wi-Fi is turned on on your smartphone. The function does not work when using only mobile data (4G/5G), unless the TV and phone are connected via a special Wi-Fi Direct mode.

It is important to consider that the video quality will automatically adapt to the speed of your Internet connection. If you're streaming 4K content, make sure your router is close enough. It is also worth remembering that some types of content protected by copyright (DRM) may block screen recording or broadcast through third-party methods, but native casting via YouTube usually bypasses these restrictions correctly.

In situations where automatic device search does not work or the list is empty, you can use manual code entry. This method is especially useful in hotel rooms or offices where the Wi-Fi network has a login page or limits communication between devices. It provides a direct connection between your Google account and your TV.

First, launch the YouTube app on your Samsung TV. Go to the section Settings (gear icon) and select the item Link with TV code (Connect using TV code). A blue digital code and a QR code will appear on the screen. This information is valid for a limited time.

Now take your smartphone. Open YouTube, click on the profile avatar in the corner and select Settings → Watch on TV. Press the button Enter the code and enter the numbers displayed on the TV screen. After confirmation, the devices will instantly connect and you can control playback.

What to do if the code is not accepted?

If the code is not accepted or writes an error, make sure that the correct date and time are set on both devices time. Clock desynchronization can lead to security errors during authorization. Also try rebooting the router.

This method is good because it binds the session specifically to your Google account. You instantly have access to your browsing history, subscriptions and playlists, all synced in real time. After finishing watching, do not forget to unlink the device in the TV settings if you are using someone else's screen.

Using AirPlay 2 technology on Samsung TVs

Although the question concerns Android, it is worth mentioning that modern Samsung TVs support the protocol AirPlay 2. This may seem irrelevant to Android users, but there are third-party AirPlay emulator apps for Android that allow you to use this data channel. This can be a fallback option if Samsung's standard methods fail.

However, for iPhone and iPad owners, this is a native feature. On Android, we more often rely on the Google Castprotocol, which is an analogue of AirPlay in the Google ecosystem. If your Samsung TV supports AirPlay 2, this indicates the presence of a modern Wi-Fi module and up-to-date firmware, which guarantees better compatibility with Android smartphones through standard means.

In the Samsung TV settings, go to the General → AirPlay setupsection. Make sure the feature is enabled. Although we are talking about Android, having active AirPlay support sometimes helps improve the overall network visibility of the device, as it activates additional discovery services in the background.

Features Smart View YouTube Cast Activation code
Type connections Screen mirroring Streaming Account linking
Battery consumption High Low Low
Ease of control Medium (screen required) High (remote control) High (remote control)
Video quality Depends on the phone Up to 4K HDR Up to 4K HDR

As can be seen from the table, for watching video the most optimal is to use the built-in cast or activation code, as they provide the best picture quality and minimal load on the smartphone. Mirroring should only be used to demonstrate content that is not available in online services.

Solving common connection problems and errors

Despite the simplicity of the technology, users often encounter difficulties. The most common problem is that the TV is not visible in the list of available devices. In 90% of cases this is due to the fact that the devices are on different subnets. Check if the “Guest Network” function is enabled on the router for one of the gadgets, as it isolates the devices from each other.

Another reason could be an outdated application YouTube on the TV. Go to the app store Apps on Samsung TV, search for YouTube and check for updates. If the update doesn't happen automatically, try uninstalling the app and installing it again. This will clear the cache and reset possible configuration errors.

If the video slows down or constantly buffers, try lowering the playback quality in the player settings on the TV. Rebooting your network equipment can also help: unplug the router for 10 seconds and plug it back in. This will clear the ARP table and update the IP addresses.

⚠️ Attention: Antivirus apps or firewalls on your smartphone may block outgoing connections for local devices. If all else fails, temporarily disable network protection in Android security settings.

In rare cases, the problem lies in the DNS settings. Try setting public DNS servers in the Wi-Fi settings on your TV or phone, for example, from Google (8.8.8.8) or Cloudflare (1.1.1.1). This can improve the response speed of Google services and speed up the search for devices.

Frequently asked questions (FAQ)

Can I connect YouTube to a Samsung TV without Wi-Fi?

Without a wireless network, connecting using standard methods is impossible. However, you can use an HDMI cable and a USB-C to HDMI adapter to connect your smartphone and TV directly. In this case, the TV will work as a monitor, and Wi-Fi will not be required, although the Internet on the phone is still needed to download video.

Why did the sound disappear when connected via Smart View?

Often the sound remains on the phone due to Bluetooth settings or the choice of output device. Check if your phone is connected to a Bluetooth headset. You can also switch the audio source from “Phone” to “TV” in the Smart View control panel on your phone.

The video slows down when broadcasting, although the Internet is fast. What's wrong?

Delays can be caused by overloading the phone's processor when encoding the video stream in real time. Try closing background applications. If the mirroring method is used, switching to the “Cast” method through the button in the YouTube application will solve the problem, since the TV will take on the load.

How to disconnect the phone from the TV?

The easiest way is to click on the broadcast icon in the YouTube application on your smartphone and select “Stop broadcasting”. Alternatively, you can simply turn off your phone's screen or switch Wi-Fi on another device. On the TV, you can press the “Return” or “Exit” button on the remote control.

💡

For stable operation of Smart View, keep your phone's Wi-Fi module drivers up to date by installing Android system updates.

💡

The optimal scenario for watching videos is to use the Cast button inside the application, rather than completely mirroring the screen, which saves battery and improves picture quality.
