Hello, I have newer Samsung tv, I can see the tv device on my iPhone in screen mirror, but it will not connect. I have updated all iOS and tv software is up to date. I have restarted devices as well.

Hello Markjp2023,

We'd love to look into this with you. We see that you were viewing the resource: If screen mirroring or streaming isn't working on your AirPlay-compatible device.

To clarify, have you completed the following steps:

"After each step, see if you still need help. 

1. Make sure that your AirPlay-compatible devices are turned on and near each other.
2. Check that the devices are updated to the latest software and are on the same Wi-Fi network. 
3. Restart the devices that you want to use with AirPlay or screen mirroring.

If you're prompted to enter a password, you might have restrictions turned on, or you might need to adjust your AirPlay password settings."

If so and the issue persists, we have a few additional steps that may be able to correct this behavior:

"Share media to your TV and Smart Monitor with AirPlay 2

Pictures, videos, and music can be shared from your iOS devices, like iPhones, iPads, and Macs, right on your Samsung TV and Samsung Smart Monitor with AirPlay 2. You’ll need to make sure your TV and Smart Monitor are connected to the internet, and that your iOS device is connected to the same Wi-Fi network.

Note: Most mobile hotspots do not allow communication between devices even when connected to the same network. If you use a mobile hotspot for your internet connection, AirPlay will not work.

1. You may need to enable AirPlay on your TV or Smart Monitor before you can start streaming content. To do this, navigate to Settings (All Settings), select General (on 2023 models and the Freestyle projector select Connection), and then select Apple AirPlay Settings. From here, you can turn on the feature.
2. To share photos or videos, open the Photos app on your phone. Select the photo or video you want to share, and then tap the Share icon in the bottom left. 
3. Tap AirPlay, and then tap the name of the TV or Smart Monitor you want to stream to.
4. You may see a code on the screen. Enter this code into your phone to make the content appear. The image or video will display on your selected device.
5. To stream music, navigate to and open a music player on your phone, such as Spotify. Select a song, and then tap the AirPlay icon at the bottom of the screen. 
6. Next, select the name of the TV or Smart Monitor you want to stream to.
7. You may see a code on the screen. Enter this code into your phone to make the content appear. The audio will begin playing through the device you select.
8. To stop playing music, tap the AirPlay icon again and then deselect your TV or Smart Monitor.
9. Alternatively, if you were already playing audio on your phone, just swipe down on the screen from the upper right to open the control center. Then, tap the AirPlay icon on the audio player to start streaming to your desired device."
