Dear all
im the owner of a systems integration in Portugal and i did a project with Samsung Flip pro WM 65
we an issue with compatibility when we try to share the picture of Samsung with a screen beam 960 ( Miracast receiver) the connection fails.
When we select the "export page " the screen beam apears as a device registed but whe we started the process of pairing the system tryed to pair but after some seconds the connection fails.
Also we tryed with samsung monitors and the problem is the same : they appeared as a registed devices but when we tryed to make the pairing the connection fails
