Galaxy s9+ screenshare/mirroring to TV no longer works, now black screen.
Has been working fine for many months now stopped working. Screen goes black on samsung TV. Apps like YouTube will mirror/cast to tv ok.
Was there an update that has broken this?
My TV model is: QE65Q6FNA
That is odd. Do you get any error code or message when you tried to connect them? I can also see that the latest software version available for your TV is: 1270.6. Is your currently running on this one and how long have you been experiencing this issue?
I am on that version on my TV, like I said the phone can connect as I'm getting sound, but black screen for picture, normally I can see my phone screen mirrored to TV straight away.
I've had this issue at least a week.
Have you made any change recently on the phone (downloaded an app, updated the software...)? Is this also happening whilst the phone is running in Safe Mode? Please follow these steps to put your device into Safe mode: Turn off your device > Power on your device normally > As soon as you see the Samsung logo, hold the volume down key > Keep hold of the volume down key until you’re onto the home screen > Safe mode will be indicated in the bottom left corner in a small black bar.
