I was having trouble with it all day today as well. It would turn on but turn off again so after work tonight I sat down and figured out how to get it to work!!! It's working perfect!!
1st.. make sure your phone is up to date
2nd..make sure the phone and roku box is connected to the same network
3rd look for the Smart Things icon ( it is located with all your installed apps. Mine is in the Samsung icon apps. There are several apps in that one icon..all grouped together...just look for the samsung icon and you should see DSmart Things)
4th in the upper right hand corner it will say scan ..click on it and roku should show up. Click on roku and it should cast on your tv in about 15 to 30 seconds! Hope this help
