nemaju svi Smart tv -i screen mirror,u tome je i problem.
ak nađem doma, ez cast(kineski-isto izgleda ko ovaj tvoj),
pa ću probati pa javim za par dana.
ako vrijedi za j5 možda vrijedi i za j3:
My Samsung J5 doesn't have screen mirroring feature how can I add it?
You can enjoy seamless casting from apps like Netflix, Hulu, Google Play Music and Movies, Google Photos, etc. As well as casting video content from your browser, Google Chrome.
You can also use the
Google home app to enjoy straight up screen mirroring. It works really well.
