Screen mirroring option not available on samsung j7 2016.However you can cast youtube and smart view photos videos etc.but not screen mirroring.I am not aware that such simple application is not available in this phone with a price tag of 16000 whereas phone with half this price are having this feature.very annoying.i would not have bought this phone had I am aware of this.for example your are using reliance jio application like jio cinema you cannot cast it on a bigger tv screen because of this. sameway samsung smart tv now has no skype option which used to be there earlier.Otherwise it is a good phone at such price , however price could have been even cheaper though I woul suggest buying the htc 10 pro or huawei mate mobiles
