I have a LG HDTV that's is DLNA enable.
The Galaxy S5 and the TV are on the same wifi network (I checked.)

On the S5, when I turn on "Nearby Devices" it sees the TV and I allowed it.
But when in the Gallery app, when I try to cast the photo from the S5 to the TV, the TV is not listed. In fact no devices is list except the S5 itself.

The strange thing is that from the LG TV, it can see the S5 and can play the photos and videos stored on the S5.

So it appears that it is working only one way.

Any idea?
