If you want to cast videos from your smartphone or tablet to your Samsung TV, you'll need to download the SmartThings app for Android or iOS. Then, open the SmartThings app and search for your Samsung devices. To begin casting, tap the mirror screen button in the upper-right corner of the screen. Select 'Video Cast' and follow the on-screen instructions. In some cases, you'll need to install a third-party application like VidAngel.

To use the SmartThings app, you must have a Samsung smart TV. You can connect your iOS or Android device to your Samsung TV using the SmartThings app. For Android devices, you can use Quick Connect. This screencasting feature works with Android devices running Marshmallow or below. Make sure that you're on the same WiFi network with your Samsung TV. Once you've installed the app, you'll need to pair your smartphone or tablet with the TV.

Stream to Samsung TV gives you full control over your media streaming experience. You can easily adjust the volume, navigate through your content, and create playlists. You can also queue files to watch later. You can also mirror certain applications to your Samsung TV. The best part of this app is that it works with most popular media players. The only difference is that it doesn't support Flash video or HBO. If you want to cast an entire movie to your TV, you should use the Smart View option.
