Share the screen of your Galaxy phone with Smart View

Tap your TV from the list of "Available devices." Depending on the TV, you may need to enter a PIN or allow access to complete the connection. When you are done using Smart View, tap the Smart View icon on your phone, and then tap Disconnect

In the TV's setting page, tap the More options icon (the three vertical dots), and then tap Mirror screen (Smart View). If needed, give your TV permission to access your device. Once that's done, your device's screen will appear on the TV.

On some models, it may start screen mirroring automatically. Other times, you may need to swipe down from the top of your device's screen to open the notification panel. Then, tap on the Samsung DeX notification that says "Tap here to switch to screen mirorring." Now select the correct source on your TV and whatever is displayed on your phone will appear on the TV.

With casting, you can control the video on your phone, but you can also close the app and do other things without interrupting the video. Certain apps like Netflix or YouTube let you cast videos from your device directly to a big screen - there's usually a casting icon you can tap. Even if you don't have a smart TV, you can use third-party casting devices like Chromecast or Amazon Firestick to cast videos or other items.

Besides the Smart View feature that's integrated into Galaxy phones, there's also a Smart View app. However, the app has a different purpose. It's basically like a hub for your entertainment; it lets you cast different apps and streaming services, such as Hulu or Netflix, onto a TV using your phone. You can also search for movies or shows to cast on the TV.

To use this app, first download Smart View from the Play Store. Power on your TV, and then open the Smart View app on your phone. Select your desired TV from the list of available devices. The App menu will appear. Select an app, such as Netflix or YouTube, to launch it on the TV. Remember, you can also search for movies and shows.

• If your phone will not display, it may need permission from the TV. Restart your device and TV, and then try connecting again, making sure you select Allow when it displays on the TV.
  

• On a Samsung TV, you can bypass allowing permission for your device to access your TV. From Settings, on your TV, navigate to General, and then External Device Manager. Navigate to Device Connect Manager, and then select Access Notification. Set this to Off to automatically connect with the device when using Smart View. From the Device Connect Manager screen, you can also select Device List to manage the devices connected to your TV.

• If your screen keeps turning off, change the screen timeout settings. From Settings, search for and select Screen timeout. From there, adjust the settings so your phone stays on for longer.

• If the Smart View menu is minimized, tap the Smart View icon on your phone. The Smart View Control menu is only displayed on your connect device.

• If the device's image looks small on your screen, you can make it a little bigger by changing the aspect ratio. On your phone, tap the Smart View icon, and then tap the More options icon (the three vertical dots). Tap Settings, and then tap Phone aspect ratio. From there, you can choose your desired aspect ratio.
