However, many users encounter issues—the TV doesn't detect the device, the connection drops, or the picture lags. In this article, we'll look into these issues. all current wireless broadcasting methods (including hidden functions), we will explain why errors may occur, and provide a checklist for fixing them.

It is important to understand that the connection method depends on the phone model (Android or iPhone), firmware versions Samsung TV and even from the router. For example, TVs 2018–2020 often not supported AirPlay, and for Miracast Dual-band Wi-Fi is required. We tested each method on devices of different generations, from Samsung Galaxy S10 to iPhone 14 Pro, And QLED/QN90B TV series to budget models Crystal UHD.

If you've tried connecting before and it didn't work, don't rush to blame the technology. In 80% of cases, the problem lies in incorrect network settings or missed details (for example, disabled developer mode on Android). Let's start with the most reliable method—Samsung's proprietary solution.

1. Smart View: a proprietary solution for Samsung devices

Smart View - This is a proprietary technology from Samsung, which allows you to stream your smartphone's screen to your TV without third-party apps. It works on most Galaxy-devices (starting from Android 8.0) And Samsung TV (series 2016 and newer). The main advantage is minimal delays and support. Full HD (on new models - even 4K).

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

Both devices are connected to the same Wi-Fi network (2.4 GHz or 5 GHz)

The TV is in the "Device Discovery" mode (Settings → General → External devices)

The phone has geolocation enabled (required to search for devices)

Disabled VPNs and firewalls that may be blocking the connection-->

On TVs Samsung 2022–2026 Smart View automatically selects the optimal broadcast resolution, but on older models (before 2019) manual adjustment may be required. Settings → Display → Screen Resolution.

2. Miracast: A Universal Protocol for Android

Miracast — is a wireless broadcasting standard supported by most Android-devices (starting from Android 4.2) And Samsung Smart TV (series 2014 and newer). Unlike Smart View, it is not tied to a brand, so it will fit phones Xiaomi, Google Pixel or HuaweiHowever, Miracast has its nuances:

• ⚡ Needs support Wi-Fi Direct on both devices.
• 📶 Works only on one Wi-Fi network (cannot stream from mobile internet).
• 🔄 Sound delay of up to 200 ms may occur (critical for games).

Connection instructions:

1. On TV: Settings → General → External Devices → Screen Mirroring → Miracast.
2. On the phone: Settings → Connections → Screen Sharing (or Quick Settings → Cast).
3. Select your TV from the list. If prompted for a PIN, enter it on the TV screen.

Why doesn't Miracast work on some Samsung TVs?

On TVs 2016–2017 (series JU, KU, MU) Miracast may be disabled by default. To enable it, go to Service menu (enter on the remote control INFO → MENU → MUTE → POWER), then find the item Miracast Enable and set the value On⚠️ This menu is intended for service centers - change settings at your own risk!

If the connection drops, try:

⚠️ Attention: Some routers (especially with firmware OpenWRT) are blocking Wi-Fi DirectIn this case, temporarily disable network protection or use a hotspot on your phone (but then the broadcast will be via mobile data).

3. AirPlay for iPhone: How to Stream from iOS to Samsung TV

Owners iPhone or iPad can use AirPlay - technology from Apple, which with 2019 supported on most Samsung Smart TV (series QLED, The Frame, Serif, TU8000 and newer). Advantages of AirPlay:

• 🎥 Support 4K HDR And Dolby Atmos (on compatible models).

• 📱 Ability to stream individual apps (eg. YouTube or Apple TV), not the entire screen.

How to connect:

1. Make sure your TV and iPhone are connected to the same Wi-Fi network.
2. On TV: Settings → General → Apple AirPlay → Turn on AirPlay.

If AirPlay isn't working:

⚠️ Attention: On TVs Samsung 2018 (series NU7100, NU8000) AirPlay may not work reliably due to hardware limitations. In this case, use alternative methods (for example, Google Cast through YouTube).

4. Google Cast: Cast via Chromecast and built-in apps

If your Samsung Smart TV supports Google Cast (or you have it connected Chromecast), you can stream content from apps like YouTube, Netflix or Google Photos Without mirroring the entire screen, this saves battery life and reduces network load.

How does this work:

⚠️ Attention: Some applications (eg. TikTok or Instagram) block Cast broadcasting due to copyright restrictions. In this case, you'll have to use screen mirroring (Smart View or Miracast).

5. Third-party apps: when standard methods don't work

If built-in features aren't suitable (for example, if you have an old TV or an incompatible phone), third-party apps can help. We tested the top three solutions and compiled a comparison table:

Instructions for ApowerMirror (one of the most stable options):

1. Install the application on your phone and TV (via Google Play on Android TV or Samsung App Store).
2. Connect both devices to the same Wi-Fi network.
3. Launch it on your phone ApowerMirror → select Mirroring → find your TV in the list.
4. On the TV, confirm the connection.

The advantage of third-party apps is that they often work where Smart View or Miracast refuse. For example, LetsView supports broadcasting even on Samsung TV 2012–2015, if you install it through USB (more on this in the next section).

6. Alternative methods: USB, HDMI and adapters

If Wi-Fi streaming is not possible (for example, due to a weak signal or incompatibility), consider wired and hybrid methods:

• 🔌 USB cable (MHL/Slimport): Suitable for old people Samsung TV with port USB 3.0An adapter is required. USB-C/Micro-USB → HDMI (For example, Samsung EE-HG950). The downside is that the phone's battery drains faster.
• 📡 Wi-Fi adapter (for example, Microsoft Wireless Display Adapter): Connects to HDMI-to the TV port and creates an access point for Miracast. Works even without a router.
• 🖥️ DLNA/UPnP: Allows you to broadcast only media files (photos, videos, music) through applications like BubbleUPnP or Plex.

To connect via USB-C → HDMI:

1. Buy a certified cable with support DisplayPort Alt Mode (For example, Anker 810).
2. Connect your phone to the TV.
3. On your phone, select the mode Image transfer (on Samsung This DeX or Screen mirroring).

⚠️ Attention: On iPhone for a wired connection you need Apple Lightning Digital AV Adapter (official accessory for ~3,000 ₽). Cheap Chinese analogues often do not support 4K and give out artifacts.

7. Solving common problems

Even with the correct settings, streaming may be unstable. We've compiled a list of common errors and troubleshooting steps:

Problem	Cause	Solution
The TV is not in the list of devices	Different Wi-Fi subnets (for example, a phone on 5 GHz, TV on 2.4 GHz)	Connect both devices to the same network and band
Mirroring is lagging	Weak Wi-Fi signal or network congestion	Reboot your router and disconnect other devices from the network.
No sound during broadcast	A different audio output is selected on the phone (for example, Bluetooth headphones)	Turn off all Bluetooth devices, check the sound settings in Notification panels
The app returns a "Not supported" error.	Outdated firmware for your TV or phone	Update software on both devices

If nothing helps, try resetting your network settings:

• On TV: Settings → General → Network → Reset network settings.
• On the phone: Settings → System → Reset → Reset Wi-Fi and Bluetooth.

Last chance: If you need a broadcast urgently and the settings don't help, use Google Meet or Zoom on your TV (via a browser) and join the conference from your phone. This isn't mirroring, but it will allow you to share your screen in real time.

2. Connect via Lightning → HDMI adapter (wired method).

Please note: Smart View And Miracast don't work with iPhone - they only support Android.

Why does the image lag when broadcasting via Smart View?

The reasons may be as follows:

• Weak Wi-Fi signal (check the signal strength in Settings → Wi-Fi on the phone).
• Network congestion (disconnect other devices downloading files).
• Low broadcast resolution (in Smart View you can choose 720p instead of 1080p for stability).
• The TV firmware is outdated (update the software in Settings → Support → Software Update).

If the problem persists, try switching to 5 GHz or use a wired connection.

How to mirror your phone's screen to a Samsung TV without Wi-Fi?

There are three ways:

1. Wi-Fi Direct: Activate Wi-Fi Direct on TV (Settings → Network → Wi-Fi Direct) and connect to it from your phone as an access point.
