Connecting a Samsung TV to a Phone via Wi-Fi: 4 Proven Methods

Modern televisions Samsung with support Smart TV allow you to transform the screen into a multimedia center controlled directly from your smartphone. But how do you properly connect these devices? Wi-FiTo stream videos, photos, or even mirror your phone's screen without lag? This article covers all the current connection methods, including Smart View, Miracast And DLNA, taking into account the features of firmware and TV models.

The main problem users face is an unstable connection or sync errors. We'll not only provide step-by-step instructions, but also explain why. Samsung TVs from 2018 to 2023 require a mandatory software update before connecting to an iPhone for the first time. (This rule doesn't apply to Android.) We'll also reveal network optimization secrets that will speed up data transfer by 2-3 times.

If you've previously tried connecting and received messages like "Device not supported" or "Unable to find TV," after reading this article, you can fix the issue in 5 minutes. Let's start with the most reliable method—proprietary technology. Smart View.

1. Connect via Smart View (official Samsung app)

Smart View — proprietary technology Samsung, which ensures maximum compatibility between the brand's TVs and mobile devices. The application is available for Android (version 6.0+) and iOS (iPhone with iOS 12 and later), but there are some nuances: on TVs of the series QLED 2020–2023 And Neo QLED Manual activation of the function is required.

To get started, follow these steps:

• 📱 Install the application SmartThings (replaced old Smart View) from App Store or Google Play. For iPhone You will need to allow access to the local network in the privacy settings.
• 📺 On your TV, go to Settings → General → External devices → Nearby devices and enable the "Discover devices" option.
• 🔗 Launch SmartThings On your phone, select your TV from the list and confirm the connection on both devices (a PIN code will appear on the TV screen).
• 🎬 To mirror your screen, tap the TV icon in the app and select “Duplicate screen” (Screen Mirroring).

Install SmartThings on your phone|Update your TV software to the latest version|Connect both devices to the same Wi-Fi network|Enable device discovery in your TV settings|Disable VPN on your phone (it may block your local connection)

-->

If your TV does not appear in the list, check:

• 🔄 Both devices are connected to one Wi-Fi network (guest networks or repeaters may block the connection).
• 🔒 The "Power Saving" mode is disabled on the TV (Settings → Device Maintenance → Power Saving Mode), which limits background processes.
• 📶 The Wi-Fi signal is stable (at least 70% strength). If the signal is weak, use 5 GHz instead of 2.4 GHz.

2. Screen Mirroring (Miracast) – screen mirroring without applications

Miracast — a universal wireless screen sharing standard that works without any additional software. It's built into most TVs. Samsung starting from 2014 (series H, J, K, M, Q) and is supported by all Android- smartphones with version 4.2+. For iPhone this method does not fit - Apple uses its own protocol AirPlay.

Connection instructions:

1. On TV:
   • Open Settings → Connections → Screen Mirroring (or Screen mirroring).
   • Select the "Connect via Wi-Fi Direct" mode (if available).

On the phone Android:

• Go to Settings → Connections → Screen Casting (or Smart View in the notification bar).
• Select your TV from the list. Confirm the connection on the TV.

TV model	Miracast support	Max. permission	Latency (ms)
Samsung QLED (2020–2023)	Yes (Wi-Fi 5/6)	4K @ 30 Hz	20–40
Samsung TU8000 (2020)	Yes (Wi-Fi 5)	1080p @ 60 Hz	40–60
Samsung MU6100 (2017)	Yes (Wi-Fi 4)	1080p @ 30 Hz	60–100
Samsung J5200 (2015)	Partial (update required)	720p @ 30 Hz	100+

If the picture on your TV is slow or lags behind the sound:

• 📶 Switch to range 5 GHz in the router settings (reduces latency by 30–50%).
• 🔌 Connect your phone to a charger - performance limitations at low battery levels can cause lag.
• 🎮 Turn it off in games Vertical synchronization (V-Sync) in the graphics settings.

Why doesn't Miracast work on some Samsung TVs?

On models 2015–2016 (series J, K) This feature may be disabled by default due to hardware limitations of the Wi-Fi chipset. To enable it, you must:

1. Update your TV software to the latest version.

2. In the engineering menu (access via the remote control: Info → Menu → Mute → Power) enable the parameter Miracast Enable.

3. Restart the TV by holding the power button for 10 seconds.

3. Connect via DLNA to transfer media files

DLNA (Digital Living Network Alliance) is a protocol for streaming photos, videos, and music from your phone to your TV without screen mirroring. Unlike Miracast, it works on all devices including iPhone, but does not support streaming games or apps.

To configure:

1. On TV:
   • Activate DLNA in Settings → General → External devices → Playback devices.
   • Launch the Media app (Media Player) or "Photo/Video/Music".

On the phone:

• For Android: Use the default Gallery app or VLC (in the "Local Network" menu).
• For iPhone: install DLNA application (For example, 8player or AllConnect).

DLNA Features:

• 🎵 Supported formats: MP4, MKV, JPG, MP3, FLAC. For AVI or MOV Conversion may be required.
• 📡 The transfer speed depends on the router: for 4K video Wi-Fi 5 (802.11ac) or wired TV connection required.
• 🔒 On iPhone DLNA only works through third-party applications—the standard Gallery app does not support the protocol.

📊 Which connection method do you use most often?

Smart View (SmartThings)

Screen Mirroring (Miracast)

DLNA for media files

Another option

If the TV doesn't see the phone in DLNA:

⚠️ Attention: On routers with this feature enabled AP Isolation (Client Isolation) devices will not be able to "see" each other. Disable it in the router settings (Wireless Mode → Advanced Settings).

4. Connecting iPhone to Samsung TV (AirPlay and alternatives)

Owners iPhone face limitations: Samsung does not support AirPlay on most models (except QLED 2018+ And Frame TV 2020+). However, there are workarounds:

• 🍎 For TVs with AirPlay 2 (see the list of models on the Samsung website):
  1. Connect TV and iPhone to one Wi-Fi network.
  2. Open Control Center on iPhone → "Cast Screen" → select TV.

🖥️ For older models:

• Use Apple TV as an intermediary (connect it to TV via HDMI).
• Install the app on TV ApowerMirror or LetsView (requires registration).

If AirPlay doesn't work:

• 🔄 Restart your TV and router (sometimes the settings get lost) mDNS, responsible for device detection).
• 🔒 In the settings iPhone Make sure Local Network is turned on for the Home app (Settings → Privacy → Local Network).
• 📶 Make sure your router supports multicast (some budget models block it to save resources).

5. Troubleshooting connection issues

Even with proper setup, errors can still occur. Here are the most common ones and how to fix them:

Error	Cause	Solution
"Device not supported"	Outdated TV or phone firmware	Update software on both devices
"Unable to connect to the network"	Blocking ports with a router	Open the ports TCP 7676, UDP 1900 in the router settings
The screen is broadcast with artifacts	Weak Wi-Fi signal or network congestion	Switch to 5 GHz or connect your TV via cable
There is sound, but no picture.	Codec incompatibility	Use VLC for broadcasting or convert the file to H.264

If the TV Samsung does not see the phone on the local network:

⚠️ Attention: On some routers (for example, TP-Link or ASUS) the filter is on MAC-address, which blocks new devices. Add the MAC addresses of your TV and phone to the "whitelist" in your router settings (Wireless Mode → MAC Filter).

To diagnose the network:

1. Check the IP address on your TV: Settings → General → Network → Network Status.
2. On your phone, run the command in the terminal (for Android):

   ping [TV IP address]

   If the packets don't arrive, the problem is in the router or firewall.

6. Optimize Wi-Fi for stable streaming

Connection quality depends not only on the devices but also on the network settings. The following recommendations will help avoid interruptions and delays:

• 📡 Use Wi-Fi channel with minimal congestionTo do this:
1. Download the app to your phone WiFi Analyzer (Android) or Network Analyzer (iOS).
2. Select a channel in the range 5 GHz with a signal level below –80 dBm.
3. Configure the channel manually in the router admin panel.

🔧 Turn it off QoS (Quality of Service) in the router - this feature can artificially limit the speed for multimedia.

🔄 If the router is dual-band, assign it to the networks 2.4 GHz And 5 GHz different names (SSIDs). This will allow you to manually select the optimal range.

For maximum stability:

• 🛡️ Reserve IP addresses for your TV and phone in your router's DHCP settings. This will prevent address conflicts.
• 📦 If you are broadcasting 4K video, limit network usage by other devices (turn off automatic updates on PCs, phones, etc.).

7. Alternative connection methods (without Wi-Fi)

If a wireless connection is not possible (for example, due to the lack of a router), consider these options:

• 🔌 HDMI adapter:
  • For Android: use USB-C/Micro-USB to HDMI adapter (for example, Samsung DeX).
  • For iPhone: needed Lightning Digital AV Adapter (official from Apple).
