Samsung issues updates that can break things like this. Time to call it in and ask for when a fix is out if they can't set it up again.
So as of this week my Samsung Galaxy Tab S2 SM-T710 can no longer mirror to my UE48JS8500. It's has worked perfectly for a year up to this point. The tablet is on 6.0.1 and the tv is using the most up to date software. Can anyone help, it's driving me crazy!
I've done a factory reset on the tv and tried different wifi networks..no luck
