I ran npm install -g react-devtools and react-devtools as stated in https://github.com/facebook/react-devtools/tree/master/packages/react-devtools.
Which says "it should connect to your simulator within a few seconds." It works with simulator however I am trying to use a Samsung S4 and nothing shows up besides the Waiting for React to connect… screen. Are the dev-tools compatible with a real device or only a simulator?
