Owning a modern technology ecosystem opens up a wealth of multimedia opportunities, but sometimes users encounter barriers between different platforms. For example, wanting to share vacation photos or watch a movie from a streaming service on the big screen. Samsung Smart TV, using iPhone, may seem complicated due to the differences in operating systems. However, engineers have long since created bridges between iOS and Tizen, allowing for video signal transmission without unnecessary wires.
There are several proven methods for establishing a connection, each of which has its own advantages depending on your TV model and software version. Wireless broadcasting is the most convenient, since it does not require the purchase of additional accessories if both devices support the standard AirPlay 2In this article, we'll take a detailed look at the action algorithms for various use cases.
It's worth noting that connection quality directly depends on the stability of your home network. If the router is operating in a congested area or is located far from the receiver, the picture may be interrupted. Therefore, before beginning setup, make sure you are in a strong signal area. Wi-Fi.
Technical requirements and preliminary preparation
Before pairing devices, make sure your equipment meets the minimum technical requirements. Older TV models released before 2018 may not have built-in protocol support. AirPlay 2, which will require the use of alternative methods or third-party apps. Check your TV model in the documentation or on the back of the TV.
A critical requirement is that the smartphone and TV are on the same local network. This means they must be connected to the same router. If you have a dual-band router, make sure both devices are connected to the same frequency (either 2.4 GHz or 5 GHz), although modern routers often group them under a single name.

- 📺 TV Samsung series 4, 5, 6, 7, 8 (2018 models and newer) or older Q, S series.
- 📡 Stable network connection Wi-Fi with internet access for initial activation.
- 🔄 Updated software on both devices to the latest versions.
It is also recommended to update the TV firmware via the settings menu, as support for new protocols is often added by the manufacturer post-factum. Go to Settings → Support → Software Update and start checking for updates. If the system prompts you to install a new version, accept it and wait for your device to reboot.
Using the built-in AirPlay 2 feature
The simplest and most native way of transmitting images is implemented through technology AirPlay 2, which Apple has implemented in Samsung TVs since 2018. This method doesn't require installing additional apps on your smartphone and works at the system level. To get started, you need to activate the feature on your TV.
Take your remote control and go to the settings menu. Find the section General → AirPlayMake sure the slider is set to "On." You can also configure security settings here, such as requiring a code each time a new device connects or restricting access to devices on the same network.
⚠️ Note: If you're in a public place or using a guest Wi-Fi network, enable the passcode requirement to prevent unauthorized access to your screen.
After activation on TV, take your iPhoneOpen the Control Center (swipe down from the upper-right corner on models with Face ID or swipe up on models with a home button). Tap the "Screen Mirroring" icon (two rectangles). Select your Samsung TV from the list of available devices.
A permission request may appear on the TV screen. Use your remote to select "Allow." If a code is required, enter it on your smartphone. Your phone's image will then instantly appear on the big screen. To stop streaming, open the control center again and tap "Stop Repeat."
☑️ Checking AirPlay settings
Broadcast via the Samsung SmartThings app
If the built-in AirPlay doesn't work for some reason, or your TV is an earlier model but is "Smart", you can use the proprietary app Samsung SmartThingsThis is a universal remote control that can also stream media files and your smartphone screen.
Download the app SmartThings Download the app from the App Store and install it on your iPhone. Open the app and sign in to your Samsung account (or create one). The app will automatically scan the network and prompt you to add your TV. Follow the on-screen instructions to pair, confirming the PIN displayed on the TV.
After successfully adding the device to the list:
- Select your TV from the list of devices inside the app.
- Click on the "Mirror Screen" button.
- Confirm the request on your phone and TV.
This method is especially useful if you need to control not only the streaming but also other TV settings from your phone. However, keep in mind that latency when using the app may be slightly higher than with native AirPlay, which is noticeable in fast-paced games.
Why might SmartThings not see my TV?
The app may not detect the device if AP Isolation is enabled on the router. This feature prevents devices on the same Wi-Fi network from communicating with each other. Also, make sure VPN services that could change the network gateway are not enabled on your phone or TV.
Streaming videos from apps (YouTube, Netflix, Kinopoisk)
A scenario where you need to stream not the entire smartphone screen, but a specific video from an online cinema deserves special attention. This is achieved using technology Google Cast or streaming services' own protocols, which often work more reliably and efficiently than simple screen mirroring.
Launch an app like YouTube or Netflix on your iPhoneMake sure the app and TV are connected to the same Wi-Fi network. In the video player interface, find the streaming icon (a rectangle with waves in the corner). Tap it.
In the list that opens, select your Samsung TV. The video will start playing directly on the TV using its internet connection, while your phone acts as a remote control. This allows you to pause the video, change the volume, or even close the app on your phone without interrupting your viewing.

Wired connection via Lightning to USB-C adapter
In situations where the wireless network is overloaded, Wi-Fi is unstable, or maximum image quality without compression is required, a cable connection is the only reliable solution. For modern iPhone models with a USB-C port, Lightning or USB-C special adapters will be required.
You will need an original adapter. Apple Digital AV Adapter (for Lightning) or USB-C to HDMI Adapter (for iPhone 15/16 and iPad). Connect the adapter to your smartphone, then connect it to your TV using a standard HDMI cable. The TV will automatically detect the new signal source.
Using the remote control, switch the signal source (button Source or Input) to the corresponding HDMI port. The iPhone's image will appear on the screen instantly. This method ensures the absence of compression artifacts and lag, making it ideal for presentations or gaming.
⚠️ Please note: Using cheap, uncertified adapters often results in audio not being transmitted or intermittent picture loss. For stable operation, we recommend using accessories marked MFi (Made for iPhone).
Solving common connection problems
Even if you follow all the instructions, users may encounter technical issues. Often, the problem lies in the network settings cache or IP address conflicts. If the TV isn't visible in the AirPlay list, try rebooting the router by completely unplugging it for 10-15 seconds.
Another common cause is having Do Not Disturb or Sleep mode enabled on your iPhone, which can block some data transfer features. Also, check if your phone has an active VPN that reroutes traffic through other countries, disrupting the local connection to the TV.
If the issue persists, reset your iPhone's network settings. Go to Settings → General → Transfer or reset iPhone → Reset → Reset Network SettingsThis action will delete saved Wi-Fi passwords, but often resolves issues with device visibility on the local network.
