Samsung often face the need to transfer photos or videos from a mobile device using wireless data transfer protocols.
The main tool for achieving this task is technology AirPlay 2, which is built into the iOS operating system and supported by modern TVs of the Korean brand. Alternative methods also exist, such as an app SmartThings or third-party utilities if standard methods don't work for some reason. Understanding the principles of a local network WiFi will help to avoid delays and desynchronization of sound.
In this article, we'll cover every step of pairing devices in detail, from checking firmware versions to fine-tuning image quality settings. You don't need to be a networking expert to establish a stable connection between your Apple device and TV. The key is to follow the steps consistently and take into account the specifics of your home network.
Checking compatibility and preparing equipment
Before you begin setup, you need to make sure that your equipment is technically ready to work with wireless media transmission protocols. iPhone 12 supports the standard AirPlay 2 "out of the box", but the TV Samsung The TV must be a 2018 model or newer. Older Smart TV models may not have built-in AirPlay, requiring additional adapters or software.
A critical requirement is that both devices are on the same subnet. This means that both the smartphone and TV must be connected to the same router. If you have a dual-band router, make sure both devices are connected to the network. 2.4 GHz, or to the network 5 GHzSeparating devices into different frequency ranges can sometimes prevent them from detecting each other.
⚠️ Attention: Some corporate or guest WiFi networks have client isolation, which prevents devices from seeing each other. Under these conditions, connecting is impossible without changing the router settings.
It's also worth checking for software updates. On your TV, go to the menu Support → Software Update and run the test. For iPhones, keeping your iOS version up-to-date is also important, as Apple regularly improves AirPlay stability in new system versions.

After activating this feature, a four-digit code may appear on the TV screen. This is a security measure to prevent unauthorized access. If you've enabled the code request, you'll need to enter these digits the first time you connect your iPhone.
What should I do if the AirPlay item is not in the menu?
If you can't find AirPlay settings, your TV model may not support this feature natively. Try updating your TV firmware to the latest version. If updating doesn't help, try alternative methods using streaming apps or HDMI adapters.

Using the Samsung SmartThings app
If standard AirPlay is unstable or you need deeper control over your TV, use the official app SmartThingsThis is a universal remote control for the Samsung ecosystem that not only allows you to stream content but also manage your TV settings.
Download the app from App Store and launch it. The program will automatically scan the network and prompt you to add the found TV. Click on the device and confirm the pairing by checking the code on the TV and smartphone screens. Once the device is added, you'll have access to the extended menu.
In the application interface, select the option Screencasting or the "Smart View" icon. This will mirror your iPhone desktop to your TV. The advantage of this method is that it often works more reliably when transferring photos and videos from the gallery, as it uses optimized codecs.

The app also allows you to create automation scenarios. For example, when you launch a video player on your iPhone, the TV can automatically turn on and switch to the desired signal source. This requires more in-depth configuration in the section Automation.
Streaming videos from apps (YouTube, Netflix)
Streaming content from streaming services deserves special attention. In apps like YouTube, Netflix or Kinopoisk technology is used Cast (or similar) that works differently than simple screen mirroring.
Open the video in the iPhone app and look for the rectangle icon with WiFi waves in the corner. Tap it to see a list of devices. Select yours. Samsung TVIn this case, the phone acts only as a remote control, and the video is downloaded by the TV directly from the internet.

The advantage of this method is that it drains your iPhone's battery minimally, allowing you to use your phone for other tasks without interrupting your viewing experience. Furthermore, the image quality is often higher, as the TV decodes the video stream internally using its processor.
Troubleshooting and troubleshooting
Even with proper setup, technical difficulties may arise. The most common issue is that the TV doesn't appear in the list of available devices on the iPhone. In this case, the first step is to reboot the router. Often, the network equipment cache is blocking the discovery of new clients.
The second reason is a mismatch in regions or security settings. Make sure AP Isolation isn't enabled on your router. Also, check if your firewall is blocking the ports required for the protocol. Bonjour, which is used to detect Apple devices.
If you see a picture but no sound, check the audio output settings on your iPhone. Sometimes the system mistakenly continues to output sound through the phone's speaker or connected Bluetooth headphones. Switch the audio output in Control Center.
- 🔄 Reset your TV's network settings using the menu
General → Network → Network Reset. - 📡 Move closer to the router to avoid interference and weak signal.
- 📲 Remove the TV from the list of trusted devices on your iPhone and try connecting again.
In rare cases, the problem lies with the antivirus software on the router or DNS settings. Try temporarily disabling traffic filtering or setting up a static DNS (for example, Google's). 8.8.8.8) in the WiFi settings on the iPhone.
Alternative ways to connect without WiFi
If a wireless connection is not possible or unstable, there is always a wired option. iPhone 12, which has a Lightning port, you will need an adapter Lightning to HDMIThis is an official solution from Apple or certified analogs (MFi).
Connect the adapter to your phone and then connect the HDMI cable to your TV. Switch the TV's signal source to the appropriate port. HDMIThe image will appear instantly, without the delays and compression artifacts typical of WiFi.
This method is ideal for gaming or presentations, where every millisecond of response is crucial. However, it does limit mobility, as the phone is physically tethered to the TV with a cable. It's also worth considering that the adapter takes up the charging port, so for extended use, you'll need an adapter with an additional Lightning connector.
Do I need an original Apple adapter?
For stable operation and high-resolution video streaming (1080p and 4K), we strongly recommend using the original adapter or certified replacements. Cheap Chinese copies often perform poorly, run hot, or lack DRM protection, which can prevent videos from playing.
Why doesn't the TV detect the iPhone after updating iOS?
After major iOS updates, privacy settings are sometimes reset. Check your phone's settings under "Privacy" → "Local Network" and ensure the toggle next to the app you're using to stream (or system AirPlay) is enabled.
Is it possible to connect an iPhone to an old Samsung TV without Smart TV?
Yes, but only via a wired Lightning-to-HDMI adapter. Wireless methods require a WiFi module and a Smart TV operating system on the TV. For older models, you can purchase an external set-top box (such as an Apple TV or Android Box) that will add Smart TV functionality.
