- 📂 Folder structure: The TV reads nested directories, but navigation can be inconvenient.
Wired connection via HDMI and adapters
If you need to transmit images in the highest quality and without lag, a wired HDMI connection is the undisputed leader. To implement this method on a smartphone, you will need a special adapter, since direct connection of the phone to the TV with an HDMI-HDMI cable is impossible without an adapter.
Owners of modern Android smartphones with a USB Type-C port can use adapters that support the technology. MHL or Alt ModeThese adapters allow you to transmit video signals directly to your TV's HDMI input. Apple users will need a Lightning to HDMI adapter or a USB-C to HDMI adapter for new iPhones.

Samsung SmartThings Local Area Network App
Official app SmartThings Samsung's Smart TV is a powerful tool for managing your smart home ecosystem, but it's also great for streaming media files. The key requirement is that both devices must be connected to the same network, but this network can be a local network created by the phone itself (modem mode) or a TV.
If your TV and smartphone support a shared local network without internet access, SmartThings lets you stream photos from your gallery directly to the screen. The app will automatically detect your TV and prompt you to select content to play.
The app's interface is intuitive: select the "Media" tab, specify the source (your phone's gallery) and the target device. The system will automatically select the optimal codec for compression and image transmission to minimize latency.

|---|---|---|
| Photo broadcast | Displaying a slideshow on TV | SmartThings app |
| Control | Remote control on a smartphone | Samsung Connected TV |
| Gallery | Access to cloud and local files | Samsung account |
| Multiroom | Broadcast to several TVs | Several Samsung devices |
Using DLNA and local servers
Technology DLNA (Digital Living Network Alliance) allows you to stream media content between devices on a local network. On Samsung TVs, this feature is often called AllShare or simply "Media Player." The idea is that the smartphone acts as a server and the TV as a client.
To implement this method without an external router, you need to enable the "Mobile Hotspot" feature on your smartphone, but don't connect it to a mobile network; instead, simply create an access point. Then connect your TV to this access point (the password is usually specified in your phone's settings).
Once the connection is established, launch any DLNA server on your phone (for example, BubbleUPnP or the built-in "Cast" feature in the Gallery). The TV will see the phone as an external storage device, and you can access photo folders directly from the TV interface.
This method is advantageous because it doesn't require installing additional apps on the TV; all control is done via the remote control. However, transmission speed may vary depending on the smartphone's Wi-Fi network strength.

Comparison of methods and selection of the optimal option
The choice of image transfer method depends on your priorities: speed, quality, or convenience. If you need to quickly display one or two photos, a USB flash drive is the easiest solution. For presentations or viewing albums in high quality, an HDMI cable is a better choice.
Wireless methods like Wi-Fi Direct and DLNA are convenient for group viewing when cables might get in the way. However, they require more careful setup and can be sensitive to the distance between devices. It's also important to consider your operating system version. gadget.

Frequently Asked Questions (FAQ)
Is it possible to transfer photos to an old Samsung TV without Smart TV?
Yes, for older models that don't support Smart TV, the only wireless option is to use external set-top boxes (such as Chromecast or Miracast adapters) connected via HDMI. Without these, the only options are a USB flash drive or an HDMI cable with an adapter.
Why doesn't the TV see photos on the flash drive?
Most often, the problem lies in the drive's file system (FAT32/exFAT is required) or the image format itself. Try converting the photos to JPEG or checking the flash drive on your computer.
Does AirPlay work on Samsung without a Wi-Fi router?
For AirPlay 2 to work on Samsung TVs, both devices (iPhone and TV) must be on the same network. You can create a hotspot on your iPhone and connect your TV to it, but standard AirPlay may require internet access for initial authentication.
How to improve the quality of the transmitted image?
Use a wired HDMI connection for maximum quality. Among wireless methods, Wi-Fi Direct (5 GHz) provides a better picture than standard DLNA over 2.4 GHz.
Does the TV take internet from the phone when connected?
When using Wi-Fi Direct to mirror your screen, the TV typically doesn't have internet access; only the local channel is used. When connecting via a hotspot, the TV can access the internet if mobile data is enabled on the phone.
