My first drone ever (Spark) arrived by FedEx yesterday.  I fully charged the battery & controller, and downloaded the Go app into my Samsung Galaxy J7.  So far so good.  Next, the app told me to connect the phone to the Controller's Wifi.  I connected, but message says "INTERNET MAY NOT BE AVAILABLE message.
Has anyone else has same problem with the same phone?

That's not a problem, since you are on the controllers wifi you wont have internet coming from it (the controller), i have the same phone but i use it as my cell, and use an old phone for the spark and use otg with it.

Get a iPhone they have no issues

And cost more than a spark...

Please do not feel worry about it. Since spark use wifi connection, your phone will fail to connect the local wifi. Please inform us if you still have doubt.

That is pretty normal ("INTERNET MAY NOT BE AVAILABLE"), because your RC/Spark is not a Internet-wifi ;-)
Which J7 model is yours? I have tried a 2015 model once, which was not be able to handle the Go4 stuff

it is a model for AT& T that I purchased maybe six months ago (so it probably is a different edition that yours).  I figured the part about "internet may not be available"  But another issue that I am having is that it works with the controller, but I cannot seem to use it without the controller.  If I turn off the controller and just connect the J7 phone with the Spark, my phone cannot find the Spark's wifi.  Go figure
