Mandatory conditions:

  • 📱 Android smartphone with OS version not lower Android 8.0 (for stable operation Wi-Fi Direct).
  • 📺 Smart TV with support Wi-Fi Direct, Miracast or Google Cast (check the settings section Network → Wireless Networks).
  • 🔌 Phone charger: The process may take 10-30 minutes, and if the smartphone battery runs out, the setup will be interrupted.
  • 📶 Access to the router: you will need the network name (SSID) and password (if the network is protected).

  • 🖥️ Laptop or tablet (if you need to create an access point, but your smartphone does not have this function).
  • 📄 User manual to the TV (to clarify the model and firmware version).

If your TV was manufactured before 2016, you may need firmware update. Obsolete models (eg. Samsung Series 5 or LG LB650V) may not support modern wireless protocols. In this case, the only option is to connect via LAN cable or purchase of external Wi-Fi adapter (For example, TP-Link TL-WN725N).

      The distance between devices is no more than 5 meters|

      Bluetooth is enabled on both the TV and phone (sometimes required for initial synchronization) -->

      3. Method 2: Setting up via manufacturer's applications

      Every major brand offers its own TV control app. It not only replaces the remote control but also allows you to set up Wi-Fi, even if the physical remote is lost.

      Popular apps:

      Brand TV Application name Download link Minimum Android version
      Samsung SmartThings Google Play 6.0
      LG LG ThinQ Google Play 7.0
      Sony TV SideView Google Play 5.0
      Xiaomi Mi Remote Google Play 4.4

    What should I do if the app doesn't find my TV?

    1. Make sure your TV and phone are connected to the same network (even if it's a mobile hotspot).

    2. Restart both devices.

    4. Update your TV firmware and smartphone app to the latest version.

    5. If nothing helps, try another application (for example, Unified Remote for universal control).

    4. Method 3: Connecting via an access point (hotspot)

    If the TV does not support Wi-Fi DirectIf you don't have a remote control, you can temporarily share the Internet from your smartphone and set up the main connection through the router's web interface.
