Just upgraded my Samsung Note 4 to a Samsung Note 8. Could not get Note 8 to connect to the Spark. Was able to get through to DJI tech support and was told the Note 8 is not supported by DJI. Asked when support would be available...response was they didn't know. I'm researching a possible downgrade to an earlier version of Go4 that might be a temporary fix but in the mean time...caveat emptor...
