I am not given the option to mirror on my Samsung Smart TV.
I'm connected to the same network
I can use as remote on my GalaxyS21 but that's about it.
Was working fine before updating my phone
Solved! Go to Solution.
Typically I'd use smart view. Swipe down twice from the notification bar. Select smart view. You may have to add it if it doesn't appear in the list. TV should show up and select it. Press allow on the TV if asked.
