I have a Samsung Galaxy S3 that is on the same wireless network as my Samsung Smart TV. I have already synced my phone and smart TV. I can sign in on my smart TV and see all my media files that are on my Samsung Galaxy S3. On my phone, when I tap on "Settings" "More Settings" "Nearby Devices" "Allowed Devices List" it shows my TV is allowed. But, when I'm on my S3 and want to share a single picture, video, or song to my Smart TV and select "Scan for nearby devices", a small message at the bottom comes up after a few seconds that says "No Devices Found. Scanning for nearby devices will continue in the background". Also when I try to search for my smart TV in "AllShare Cast" it says there are no devices found. Why is it not finding my Smart TV, even though my phone and smart TV are already linked together? Thanks so much for any help!
