Samsung RC-2 Remote Control

No. It is only compatible with select Samsung point & shoot 35mm film cameras. The Samsung Galaxy S7 is not compatible for use with infrared remotes, and does not have an infrared receiver built into the smartphone.

No, it is not. The Samsung RC-2 Remote Control is designed for use with select point & shoot film cameras, not for digital cameras, and is not listed as an accessory for the Samsung NX300. The only remotes that are currently indicated by Samsung for use with the Samsung NX300 Digital Camera is the Samsung SR2NX02 Remote Shutter Release, B&H # SASR2NX02, or by using a smartphone or tablet with the Samsung SMART CAMERA App installed on the device.

No, that remote is not compatible.The camera can work with smart devices and it works with a wired remote.

Unfortunately the Samsung website does not list the RC-2 as a compatible accessory for the Samsung Gear 360.

While Samsung's RC-2 Remote Control for Select Point & Shoot Film Cameras (B&H# SARC2) will work with many Samsung 35mm film point and shoot cameras, it does differ in its appearance from the one shown in the manual for your specific camera model (see p.53): https://bit.ly/3FvYOwH Given that fact, and the fact that a couple of decades have gone by since it was in common use, at this point we are not able to test it nor locate the sort of detailed documentation for the RC-2 that would provide a sufficient listing of model compatibility. Given its low price, however, as well as the fact that the manufacturer does state that it's compatible with most of their 35mm point and shoot cameras, you may feel that it's well worth trying it.
