It is critical that both devices are on the same router subnet, as Wi-Fi Direct connection without a router is not supported by all models and often requires manual activation in the menu.
In this article, we will examine in detail all available synchronization methods and consider built-in functions Smart View And AirPlay 2We'll also discuss third-party solutions for situations where standard protocols don't work. You'll learn how to configure transmission quality, minimize latency, and what to do if your TV stops detecting your mobile device.

Make sure your Samsung TV has the latest software version. Outdated firmware may not support new codecs or security protocols used by modern smartphones. An update often resolves issues with the device not appearing on the list of available screens.
⚠️ Important: If you're using a dual-band router, make sure both your TV and smartphone are connected to the same frequency (either both to 2.4 GHz or both to 5 GHz). Some routers isolate devices on different frequencies, making it impossible for your phone to detect your TV.
It's also worth paying attention to power consumption. High-definition video streaming (Full HD or 4K) significantly drains the battery of your mobile device. It is recommended to keep the phone connected to a charger or have it handy. Power Bank, especially if you plan on watching for a long time.

In such cases, it's recommended to pause background downloads on other devices.
Connecting iPhone and iPad via AirPlay 2
For ecosystem users Apple the process is simplified as much as possible thanks to the support of technology AirPlay 2 In modern Samsung models, this feature is built directly into the operating system. iOS And iPadOS, so there is no need to install any additional applications.

- 🎬 Web Video Caster — ideal for broadcasting video from websites.
- 📂 BubbleUPnP — a powerful tool for working with DLNA servers.
- 📺 TV Cast for Samsung — a specialized solution for browser broadcasting.
When using third-party software, it's important to be aware of advertising. Free versions of apps often contain intrusive banners that can block part of the screen or interrupt playback. Paid versions are free of these drawbacks and typically offer a more stable connection.
Solution and troubleshooting
Even with proper configuration, situations may arise where devices cannot see each other or the connection constantly drops. The most common cause is IP address desynchronization or a temporary failure in the router's network stack. First, try rebooting the router by unplugging it from the power outlet for 30 seconds.
If the problem persists, check your router's firewall settings. Some models have an "AP Isolation" feature that prevents devices within the network from communicating with each other. This feature should be disabled in the Wi-Fi security settings.
It's also worth checking if you have an ad-blocking app or a VPN installed on your phone. Such programs can alter network routes, making the TV unvisible to your smartphone. Try temporarily disabling the VPN and then trying to connect again.
