My phone is updated, reset as is the Samsung TV and screen Mirroring just disconnect s as their is a hdcp not ready or compatible error.
Phone finds the TV connects and disconnects due to the above. Tried on 2 different TV same issue. I would prefer a clever tech answer not the first 50 basic it questions you have on your list I'm not computer illiterate. Other phone works a Samsung. It's not anything else other than screen mirroring that has the problem.
Alot of hotels use this as there primary access for peoples entertainment so would be good to get an answer.
