I've just bought an 40PFK6510/12 smart tv. I have two problems.

1) I cant use spotify on my TV. I searched the google play store but could not find any spotify app. Also i cant use the spotify
connect feature. (iphone 4 iOS 7)

2)Can i pair youtube app in my iphone to tv? (send to TV function) I mean when i am watching a youtube video on my iphone, can i mirror it to tv?
Some other brands can do this. But i cant find a pair option in youtube app on my tv. you can see an example in following link. https://www.youtube.com/watch?v=YJ7cD8sHXF8
