Hi. I recently bought a samsung tv model code UE49MU6402 and I've been trying to mirror screen my android phone operating android 7.1.1. It shows the TV name at the cast menu at settings but when i try to connect it, it says connected and then unavailable. I have allowed access from the notifications when the tv asked to and i can cast videos from YouTube or from the Smart View app, even use the tv remote from my phone but the screen mirroring doesn't work. I would appreciate some help.
