Hi, updated my phonew to marshmallow and now I can't mirror z3 screen to my samsung smart tv. It worked before. It was the uplate for sure because all other my marshmallow phones work with the tv. Tv is updated. Although it works on my other LG smart tv. Please advise. Can I go back to lollipop? Manyou thanks
