A:AnswerI have the Galaxy S9. But if the Galaxy J7 has wireless charging then it should work. You can always take your phone to best buy and put it down on any of the demo charge plates to make sure.
A:AnswerI imagine so, I have the S9+ and it works just fine. It also works on my mother's S6 so as long as you have the wireless charging compatibility, which I'm sure the note has if the S6 has it, it should work just fine.
