A:AnswerHello Marilyn,
I understand that you left us this question because you were having doubts about this. Our Universal 2 Device Remote is not smart enabled meaning that it will not control the smart features of your Samsung TV. I would advise to search for Samsung replacement remote that will be completely compatible with your TV.
We are always here to help you in case you need any further support with it and thanks for your interest in this product.

A:AnswerHi, Bob.
Thank you for sharing your inquiry with us. All of our Roku TVs are Smart and have smart functions as a primary source. Even if you pair a universal remote to it, you will not be able to enter numbers in order to change channels.

A:AnswerYou bought the wrong remote. I had the same problem and could not solve it with the best tech help. Bottom line, cheap Chinese crap at Best Buy.
