Universal remote setup with Samsung tv and Roku box

Tivoburkee(our resident remote expert) often recommends the All-For-One universal remote.  I don't have any experience with it myself, but I trust his judgement.  🙂

I know you said "box", but keep in mind that no universal remote can control a stick that plugs directly into an HDMI port without the need for an HDMI cable.

Hi svharrison, thank you for reaching out to us in the Roku Community!

We understand that you're searching for a universal remote for your Samsung TV, and we're here to assist you. It's important to note that you may encounter compatibility issues with a universal remote as Roku devices are specifically designed to work with Roku remotes. This particular issue might lead to complications because of the incompatibility with the device's operating system. Therefore, we highly recommend utilizing a Roku remote or the Roku mobile app for Roku devices and TVs to ensure optimal functionality.

We deeply value your understanding and are fully committed to providing any further assistance you may require.

Thanks,
Jharra
