I bought a allshare cast for my TV but I don't have the settings or app for allshare like I did on my note 3. Did they do away with it? I can mirror my phone to the screen but that's about it. Any help greatly appreciated.
Use the screen mirroring setting. If you're talking about something else, can you be more specific. Because that's the only option on my Note 3 as well, so I'm not sure what other settings you might be referring to having had on your Note 3.
In case this is what you're looking for, there is the Samsung Link app which you can find in the galaxy app store and possibly on google play.
