For example, if you're using an Android device, you must go into Settings > Display > Cast menu and enable it from there. On iOS devices, this can usually be found under Control Center > Airplay (or Screen Mirroring). With your phone enabled for screen mirroring, it's time to turn on your smart TV's feature.
Just tap the TV with your phone and it will be mirrored. Check if the TV's Smart View function is turned on (Settings > General > External Device Manager > Device Connect Manager > Access Notification).
Check the distance between your phone and the Samsung TV screen. Don't keep a long distance between your Samsung smart TV and Android device. Keep your phone or laptop within 10 meters (33 feet) of your TV for a stronger connection. The screen mirroring feature may not work when you go beyond a specific distance.
Wirelessly Screen Mirror to a Samsung Smart TV
Smartphones running on Android 4.2 or newer operating systems include a screen mirroring technology. For example, if you're using a Samsung smartphone to screen mirror, it may include something called Smart View, Samsung's version of screen mirroring.
AirDroid Cast is the best screen mirroring app because it is available for all major platforms, including Windows, Mac, Android, iOS, and TV. It allows you to screen mirror anytime and anywhere through web browser without installation. It is the only one app that supports web version.
Samsung TVs can connect to variety of Bluetooth devices, including speakers, soundbars, headphones, keyboards and mice, and gamepads.
At the Google Home app's main screen, tap the name of your device. At the bottom of the screen, tap the option for Cast my screen. A message pops up to explain about mirroring your device. Tap the option for Cast screen and then tap the Start now button.
Make sure that your AirPlay-compatible devices are turned on and near each other. Check that the devices are updated to the latest software and are on the same Wi-Fi network. Restart the devices that you want to use with AirPlay or screen mirroring.
From your TV's Settings, select Sound, and then select Sound Output. If the option Bluetooth Speaker List appears, then your TV supports Bluetooth.
The good news is that Chromecast is available for almost any TV, even older, non-smart models. As long as your Samsung TV has an HDMI (High Definition Multimedia Interface) port, you'll be able to connect this streaming gadget and get more out of your TV.
If you don't have a smart remote or aren't sure if it is, you can still check by going to the TV's settings menu. In settings, you want to select 'Sound' and then 'Sound Output'. You'll know your TV is Bluetooth compatible if you see an option for 'Bluetooth Speaker List.
The main reason why Samsung TV Bluetooth is not working is that the Bluetooth feature needs to be manually enabled. To manually enable Bluetooth on your Samsung TV you will need to open the secret developer menu and enable BT Audio.
Make sure the devices are close enough; otherwise, they will not connect. If possible, restart the Bluetooth device. Then, restart your phone or tablet. This can help fix minor issues and may help the Bluetooth device connect again.
