Modern Samsung smartphones boast incredible screen quality, but sometimes you want to share the movie-watching experience with your family on the big screen. Luckily, wireless data transfer technologies make this possible in seconds, without the hassle of wires. You don't need complicated HDMI cables or adapters if both devices are on the same network. All you need is the right steps and ensuring your equipment supports the necessary protocols.
There are several ways to implement this task: from a built-in function Smart View Before using third-party apps and DLNA servers, each method has its own characteristics, advantages, and TV software requirements. In this article, we'll detail all the available options so you can choose the most convenient one for your situation.
Before starting the procedure, make sure that your smartphone and TV are connected to the same Wi-Fi network. This critically important condition, without which device detection will be impossible. If the router broadcasts the network on both 2.4 GHz and 5 GHz frequencies, it's best for both devices to be connected to the same band, although modern routers often combine them into a single network.
Using Smart View to cast your screen
The most popular and simple way is to use a native function Smart View, which is built into the One UI shell on Samsung smartphones. This technology is based on the standard Miracast and allows you to fully mirror the image from your mobile device's screen to your TV. You open a movie in the app on your phone, and the image appears on the big screen.
To activate this feature, swipe down from the top of the notification shade. Find the icon with the name Smart View and tap it. If the icon isn't in the quick access panel, tap the "Edit" button (usually a plus sign or pencil) and add the icon to the panel. After turning on, the phone will begin searching for available devices on your Wi-Fi network.
Your TV's name will appear in the list. Click it, and a connection permission request may appear on the TV screen. Use the remote to confirm. Your phone's screen will now be fully mirrored to the TV. You can minimize the video app and even use messaging apps, but the image on the TV will follow your actions.
☑️ Preparing for Smart View
It is worth noting that when broadcasting via Miracast The phone doesn't turn off the screen, which can drain the battery faster. Furthermore, video resolution may be limited by the Wi-Fi network. If the router is located far away or the network is overloaded, lag or image artifacts may occur.
⚠️ Note: When using Smart View, notifications from your phone (messages, calls) will also be displayed on the TV screen. To avoid embarrassing situations, activate "Do Not Disturb" or "Game Mode" in your smartphone settings beforehand.
Broadcasting via built-in Smart TV applications
If you want to watch movies from online cinemas (YouTube, Netflix, IVI, Okko), it is much more efficient to use technology Google Cast or built-in Smart TV clients. In this case, the phone acts only as a remote control, and the TV downloads the video stream directly from the internet. This frees up the smartphone's processor and ensures maximum picture quality.
Open an app, such as YouTube, on your Samsung phone. In the upper-right corner of the video or in the player interface, find the casting icon (a rectangle with Wi-Fi waves in the corner). Tap it and select your TV from the list. The video will play on the big screen, and you can control playback, volume, and rewind from your smartphone.
The process is similar for streaming services like Netflix or IVI. The main requirement is having the client app installed on the TV itself. If your TV doesn't have the IVI app, you won't be able to "cast" videos to it via Cast, but you can use screen mirroring, as described in the previous section.
Why is there a delay in video from my phone?
Lag occurs because the phone encodes the video stream, sends it over Wi-Fi, and the TV receives and decodes it. With Cast technology, the phone only sends the "play video via link" command, and the TV downloads the stream automatically, eliminating lag.
The advantage of this method is that you can turn off your phone's screen or run other demanding games without affecting video quality. Image quality in this case depends solely on your internet connection speed and the capabilities of your TV's display, not on the power of your phone's Wi-Fi module.
Setting up a DLNA server to view your media library
If you have movies downloaded to your Samsung phone's memory or memory card and you want to watch them on your TV without casting the entire screen, use the protocol DLNASamsung has a built-in "Media Casting" feature or allows the use of third-party server applications.
This is done through the application using built-in tools. Gallery or My filesSelect a video file, click the "Share" button or the cast icon, and select your TV. The TV will treat your phone as an external drive and play the file natively. However, the built-in player may have limited formats.
For advanced features, it is recommended to install a server application on your phone, for example, BubbleUPnP or Web Video CastorThey allow you to stream virtually any video file format that your TV's standard player doesn't support. The app creates a local server to which the TV connects.
| Parameter | Smart View (Miracast) | Google Cast / AirPlay | DLNA (Local File) |
|---|---|---|---|
| Video source | Phone screen | Online service | Phone memory |
| Battery load | High | Low | Average |
| Picture quality | Depends on Wi-Fi | Maximum | Original |
| Multitasking capability | No (screen visible) | Yes | Yes |
Using DLNA is especially useful for owners of older Samsung TVs that don't support modern codecs or don't have access to an app store. In this case, the phone takes over the decoding of complex video formats.
Troubleshooting connection and discovery issues
Users often encounter a situation where their Samsung phone simply doesn't see their TV in the list of available devices. First, check if client isolation is enabled on your router.AP Isolation). This security feature prevents devices within the network from communicating with each other.
The problem may also lie in the TV's settings. On Samsung models, you need to allow the connection of external devices. Go to the menu Settings → General → External Device Manager → Device ListMake sure your phone is not blocked or ignored.
Sometimes a simple restart of the network modules helps. Turn off Wi-Fi on your phone and then turn it back on. If that doesn't help, reboot the router. Older routers may not work correctly with discovery protocols when there are a large number of connected devices.
⚠️ Note: The Samsung TV menu interface may differ depending on the Tizen OS version. If you don't see the "External Device Manager" option, look for the "Device Connection" or "Connection Manager" section in the general settings.
Another common cause is using a guest Wi-Fi network. Guest networks often have software restrictions that prevent local communication between devices. Make sure both devices are connected to the main network.
Alternative streaming apps
If standard methods are unstable or don't support the required format, third-party solutions come to the rescue. SmartThings Samsung's official control center often helps "wake up" the connection if the native function is glitchy.
For advanced users, installing a server would be an excellent solution. Plex or Jellyfin to a computer connected to the same network and use their clients on TV and phone. However, if there is no server, you can use a bundle of apps for direct streaming. For example, LocalCast Allows you to send files from your phone to a TV's DLNA receiver with subtitle support.
Owners of Samsung TVs with support AirPlay 2 (2019 models and newer) can use an iPhone or iPad to cast, but Android devices can also stream content via compatible player apps that support rendering to DLNA/UPnP devices.
Keep in mind that transmission quality is highly dependent on airwave congestion. If you live in an apartment building with dozens of routers operating on the same channel, transmission stability may deteriorate. In this case, switching your router to channel 1, 6, or 11 in the 2.4 GHz band, or using the 5 GHz band, may help.
Features of connecting older TV models
Owners of Samsung TVs from series prior to 2015-2016 (such as the J or H series) may encounter a lack of support for modern wireless transmission standards. These models often lack built-in Wi-Fi Direct or Miracast. In this case, software-based methods may not work.
For such cases, there is a hardware solution - purchasing an external adapter Anycast or Google ChromecastThese devices plug into your TV's HDMI port and create an access point visible to your Samsung. Essentially, they add Smart TV functionality to your old TV.
You can also use the TV's USB port to connect a Wi-Fi adapter, if the model supports it (usually Samsung adapters). However, even in this case, functionality will be limited to the built-in browser or basic media player.
Check for firmware updates for your TV. Samsung sometimes releases patches that add support for new protocols or improve connection stability, even for models released several years ago. You can update the firmware via a USB drive by downloading the file from the official website.
FAQ: Frequently Asked Questions
Why does the picture jerk or have low resolution when watching a movie over Wi-Fi?
Most likely, your Wi-Fi signal is too weak or unstable. Try moving closer to the router, disabling downloads on other devices, or switching to a 5 GHz network, which provides higher throughput for the video stream.
Is it possible to display a Samsung screen on a TV without Wi-Fi?
Without a wireless network, you can only use a wired connection. You'll need a USB-C to HDMI adapter. Simply connect one end to your phone, the other to your TV's HDMI input, and switch the signal source (Source) to the appropriate port.
My Samsung TV isn't detecting my phone, even though we're both on the same network. What should I do?
Check your antivirus or firewall settings on your router, as they may be blocking local data exchange. Also, try temporarily disabling your VPN on your phone, as it changes your virtual address and can hide your device from the local network.
Does my old Samsung support Smart View?
Smart View has been available on Samsung smartphones since the Galaxy S4 series and later. If you have a very old phone or tablet, you may need to install a third-party screen mirroring app.
