When I launch Smart View, the display just spins and never finds any TVs. I have had this issue in two separate locations with multiple TV types. It worked several weeks ago. I can't say for sure but I think it was prior to the last systems update which my phone says happened on August 3, 2019.
My phone model # is SM-N960U1
Android Version 9
Solved! Go to Solution.
It was a bonehead error on my side. I had two issues
1) I finally checked to see that the Insignia TV I was trying with does not support screen mirroring.
2) I then went to another room and tried with another TV that is outfitted with a current Fire Stick and when I followed the instructions, it connected right away.
So, my mistake.
Apologies for causing unnecessary clutter.
