Alternative methods: Chromecast and third-party apps
If built-in tools don't work, third-party solutions can help. Install a casting app on your TV (via the store) Samsung Apps) and the corresponding software on the iPhone can create a local network for data transfer. Apps like TV Cast or Web Video Caster They often have a direct connection mode or operate via a local IP address, which can be forwarded even without access to the global network, if the devices can see each other.
Some users use devices Google Chromecast or Android TV Box, connected to the TV's HDMI port. These devices can create their own WiFi Direct access point, to which the iPhone connects to stream content. In this case, the TV acts only as a monitor, and the external set-top box handles all encoding and transmission.
